Every European email deliverability tool reviewed
Poznan, Poland
Free STARTUP up to 9,000 emails a month (300 a day) / Essential 30 at €23 a month for 100,000 / PRO 100 at €69 a month with a dedicated IP and €1.02 CPM overage / Enterprise above 1M
Free STARTUP plan, plus a trial with no card details (100 test messages a day)
Best for: Senders who need a certificate, a cheap tier and an unambiguous answer on where the data sits
EmailLabs is the tidiest answer in this category to the question a compliance officer actually asks.
It states that all data is processed in the EEA on servers in Central and Eastern Europe, holds ISO 27001 for information security and ISO 27018 for personal data in public clouds, and is run by Vercom S.A., a publicly listed Polish company rather than a startup with a landing page. For a bank, an insurer or a public body, that combination is the whole argument.
The product is a straightforward SMTP and email API service with per-message analytics, webhook events and dedicated IPs. The free STARTUP plan carries 9,000 emails a month at 300 a day on a shared IP, which is enough to run a small SaaS.
Essential 30 is €23 a month for 100,000 emails and adds Certified Senders Alliance certification, which is what buys preferential handling at GMX and Web.de. PRO 100 at €69 removes daily limits and includes a dedicated IP, with overage at €1.02 per thousand.
The limits are scope and reach. EmailLabs is a sending relay, not a marketing platform, so there are no campaigns, no landing pages and no CRM. Documentation and support lean Polish-first, and the brand carries little recognition outside Central Europe, which matters when you are the person who has to defend the choice internally.
What EmailLabs does well
- ISO 27001 and ISO 27018, the only tool here with both
- States plainly that all processing happens in the EEA
- Free tier of 9,000 emails a month on a shared IP
- €23 a month for 100,000 emails, cheaper than Scaleway above ~92,000
- Certified Senders Alliance certification from the Essential plan up
- Operated by Vercom S.A., a listed company with published accounts
Where EmailLabs falls short
- A sending relay only — no campaign tooling of any kind
- Documentation and support are strongest in Polish
- The free plan caps at 300 emails a day, which a burst will hit
- Little brand recognition outside Central and Eastern Europe
Standout feature. ISO 27018 alongside ISO 27001. It is the certification that is actually about personal data in someone else's cloud, and EmailLabs is the only provider in this category that holds it.
Paris, France
Essential: 300 emails included, then €0.25 per 1,000 / Scale: €80 a month with 100,000 included, then €0.20 per 1,000
300 emails a month included on the Essential plan
Best for: Teams already on European cloud infrastructure who want the lowest published price per email
Scaleway Transactional Email is the cheapest published rate in this category and the most disciplined product in it. Pay-as-you-go is €0.25 per 1,000 emails after 300 free; the €80 Scale plan includes 100,000 and charges €0.20 per 1,000 beyond that, with a managed dedicated IP, a 99.9% SLA and unlimited domains. Sending is over REST or SMTP, with SPF, DKIM and DMARC configured per domain and a domain reputation score in the console.
Scaleway is SCALEWAY SAS of 8 rue de la Ville-l'Évêque in Paris, registered at RCS Paris under 433 115 904, and it runs its own data centres rather than reselling a hyperscaler. For an organisation already using Scaleway for compute or object storage, transactional email arrives on the same invoice, in the same console, inside the same jurisdiction, which removes a vendor assessment rather than adding one.
The discipline cuts both ways. Marketing email is prohibited on the product, not merely discouraged. There is no inbound email at all. The Essential plan caps at five domains and one webhook per domain, and attachments are limited to a named list of formats — PDF, HTML, text, ICS, CSV, JPEG, PNG and GIF. Each recipient counts as a separate email for billing, so a message to three people is three emails.
What Scaleway Transactional Email does well
- €0.25 per 1,000 emails, the lowest published rate here
- Runs on Scaleway's own European infrastructure, not a resold hyperscaler
- Same console, same invoice and same jurisdiction as the rest of the stack
- Managed dedicated IP and a 99.9% SLA on the €80 Scale plan
- Domain reputation scoring and per-domain SPF, DKIM and DMARC
Where Scaleway Transactional Email falls short
- Transactional only — sending marketing email breaks the terms
- No inbound email, so replies need a separate service
- Essential caps at five domains and one webhook per domain
- Attachments restricted to a fixed list of file types
- Each recipient is billed as a separate email
Standout feature. It is the only transactional service here that refuses marketing mail outright, which is why its shared IP reputation is not hostage to somebody else's campaign.
Lille, France
Free 100 emails a day / Individual €10 a month (€8 annual) for 20,000-50,000 / Startup €79 (€63) for 100,000-200,000 / Scaleup €270 (€216) for 500,000-1,000,000 / Unicorn on quote. SMS is a separate credit system from about €0.04 a message
Free plan: 100 emails a day over API and SMTP, 7-day log retention
Best for: French and European teams who want email and SMS behind one API with hosting in France
Sweego is the most modern developer experience in this category: REST and SMTP sending, inbound routing, a drag-and-drop template builder, observability dashboards and SMS on the same API, with a free plan of 100 emails a day to start on. Paid tiers run €10 a month for 20,000 to 50,000, €79 for 100,000 to 200,000 and €270 for half a million to a million, with roughly a 20% discount on annual billing and a dedicated IP included from Scaleup.
The company behind it is MINDBAZ, a French simplified joint-stock company at 19 rue d'Amiens in Lille, registered as 893 278 382, with its site hosted by OVH in Roubaix. Mindbaz has been working on deliverability since 2013 for senders including Reworld Media, M6 and Prisma, which is where the routing expertise comes from. Sweego states its data centres are in France and argues on that basis that customer data is outside the reach of the CLOUD Act.
What it does not have is a paper trail. There is no ISO 27001 certificate, no SOC 2 report and no published subprocessor list, so the sovereignty claim rests on the vendor's own statement rather than an external audit. Log retention on the free plan is seven days, which is short for debugging, and the product is young enough that the ecosystem around it — libraries, integrations, Stack Overflow answers — is thin.
What Sweego does well
- Email, SMS and inbound routing behind a single API
- Data centres in France, with OVH named as the host of the site
- Free plan of 100 emails a day over both API and SMTP
- €10 a month for up to 50,000 emails, the cheapest paid entry point here
- Dedicated IP available from Startup and included on Scaleup
- Built by Mindbaz, working on deliverability since 2013
Where Sweego falls short
- No ISO 27001, SOC 2 or published subprocessor list
- Log retention is seven days on the free plan
- A young product with a small integration ecosystem
- Documentation and support are oriented to the French market
Standout feature. Email and SMS on one API from a French host: for a team that would otherwise buy Twilio for the second channel, that is one vendor and one DPA instead of two.
United Kingdom
$10 a month for the first 10,000 emails, then usage-based; every feature is on every plan
An unadvertised free plan of 100 emails a month, available on request
Best for: Teams that will not accept an American company anywhere in the chain
MailPace is the only provider in this category that answers the subprocessor question without being asked.
Its privacy policy names every one: Freethought, a UK hosting company, and Clever Cloud in the EU for servers; Hetzner in Germany for seven days of backups in two locations; AppSignal in Amsterdam for monitoring; Paddle in the UK as merchant of record; Tutanota in Germany for support email. There is no American company on that list, which is a claim almost nothing else in European software can make.
The entity is OhMySMTP Ltd, incorporated in England and Wales under company number 13200428, and the service is governed by UK law.
Sending is REST or SMTP, the API is idempotent so retries are safe, inbound email arrives as JSON webhooks, and the company publishes its median delivery time — around 1.19 seconds overall, with per-provider figures including Gmail at 0.94 seconds and Yahoo at 12.46 seconds. Pricing is $10 a month for the first 10,000 emails and usage-based above, with every feature on every plan and no add-ons.
The trade-offs are deliberate. There is no open or click tracking at all, because there are no tracking pixels — you lose engagement metrics and gain a shorter privacy policy. There is no certification to show procurement. And the company is small and independent, which is a continuity question a large buyer is entitled to ask, however good the product is.
What MailPace does well
- Complete published subprocessor list with no American company on it
- UK company, EU and UK hosting, German backups at Hetzner
- Idempotent API, inbound webhooks and published delivery-time statistics
- One price, every feature — no plan gating and no add-ons
- $10 a month for the first 10,000 emails
Where MailPace falls short
- No open or click tracking, by design
- No ISO 27001 or SOC 2 for procurement to point at
- A small independent company, which is a continuity question
- The free plan exists but is unadvertised and must be requested
- UK rather than EU establishment, which matters for some tenders
Standout feature. It publishes every subprocessor and none of them are American. Most vendors ask you to trust the summary; MailPace hands you the list.
Amsterdam, Netherlands
€55 a month for 25,000 messages on one IP and one domain, then €0.23 per 1,000, falling to €0.22, €0.17, €0.06 and €0.05 as volume rises; optional support contract €89 a month
Best for: High-volume senders who want a vendor that owns the hardware the mail leaves from
SMTPeter is Copernica's transactional relay, and Copernica B.V. sits at De Ruijterkade 112 in Amsterdam and states plainly that it runs its own servers in the Netherlands with its own technology. In a category where "EU hosted" usually means a rented region inside somebody else's cloud, owning the hardware is a materially different answer, and it is the reason to look at SMTPeter over a cheaper API.
Messages arrive over REST or SMTP. The pricing is a volume curve rather than a ladder: €55 a month covers up to 25,000 messages from one IP address and one domain, the next 25,000 cost €0.23 per thousand, then €0.22 for the following 950,000, €0.17 for the next five million, €0.06 for the next 45 million and €0.05 beyond that.
A technical support contract is €89 a month on top. At ten million messages that curve beats everything else in this category; at ten thousand it is the most expensive option on the page.
The entry price is the problem for everyone else. There is no free tier, and the €55 minimum buys one IP and one domain — a second domain means a conversation. The wider Copernica suite is a marketing automation platform with its own language and its own learning curve, and SMTPeter's documentation assumes you are already somewhere in that world. It publishes no security certification.
What SMTPeter does well
- Copernica owns and runs its servers in the Netherlands
- Volume pricing falls to €0.05 per 1,000, the cheapest here at scale
- REST and SMTP, with the delivery engine behind a large European ESP
- Dutch company, Dutch hardware, Dutch jurisdiction with no subcontracted cloud
Where SMTPeter falls short
- No free tier, and €55 a month is the floor
- The base price covers one IP and one domain only
- No published ISO 27001 or SOC 2 certification
- Documentation assumes familiarity with the Copernica platform
- Expensive for anyone sending under about 100,000 messages a month
Standout feature. Own servers, own technology, one country. At very high volume it is also the cheapest per thousand in this category, which is an unusual pairing.
Freiburg im Breisgau, Germany
Founded 1999
No public price list; quote only
Best for: German organisations that want order and system mail on the same platform as the campaigns
Inxmail GmbH has been in Freiburg im Breisgau since 1999, is registered at the Freiburg district court under HRB 5870, and employs around 150 people. That longevity is the point: procurement departments that will not sign with a two-year-old startup will sign with a company that has been sending email since before most of this category existed.
The relevant product is the SMTP mail relay alongside Inxmail's campaign platform, which means order confirmations, system notifications and CRM mail run through the same system as the newsletters, with one sender reputation and one set of templates.
Inxmail states server locations exclusively in the European Union with hosting, service and support in Germany, holds ISO/IEC 27001:2022 certified by TÜV Rheinland, and is a Certified Senders Alliance member, which is the combination German public-sector and regulated buyers ask for by name.
It is not a self-serve product. There is no published price list, no free tier and no sign-up-and-send path — pricing is a quote and deployment is a project. The orientation is German-speaking and the interface and documentation show it. For a developer who wants an API key in ten minutes, this is the wrong end of the category.
What Inxmail does well
- In business since 1999, with 150 staff and a registered German entity
- ISO/IEC 27001:2022 certified by TÜV Rheinland
- Server locations exclusively in the EU, hosting and support in Germany
- Certified Senders Alliance member, which helps at GMX and Web.de
- Transactional relay and campaign platform on one sender reputation
Where Inxmail falls short
- No public pricing — quote only, with a sales process attached
- No free tier and no self-serve sign-up
- Strongest in German; documentation and support are German-first
- Far heavier than a transactional API for a team that only needs sending
Standout feature. Server locations exclusively in the EU, stated by a company that has been German-registered for 26 years. That is a sentence procurement can put in a file and stop worrying about.
Munich, Germany
No public price list; quote only
Best for: Enterprises that need guaranteed throughput and their own choice of processing location
Retarus is the enterprise end of this category. retarus GmbH sits at Aschauer Straße 30 in Munich, registered as HRB München 101134, and has been in business for over 33 years by its own account. Its transactional email service sells guaranteed throughput rates and inbox placement to organisations sending at volumes where a queue backing up is an incident with a cost attached.
The infrastructure argument is the strongest here. Retarus operates five data centres across fifteen locations on three continents, self-sufficient and redundant, explicitly not built on hyperscalers — so processing location is a contractual choice rather than a region dropdown, and the company controls the hardware end to end. It is Certified Senders Alliance certified, and documents its infrastructure against GDPR, HIPAA, Sarbanes-Oxley, PCI DSS and TISAX, which covers most regulated industries in one sweep.
Two honest caveats. The data centre estate includes the United States and APAC, so "Retarus is German" describes the company, not automatically the processing — the location is something you specify in the contract and should verify in writing. And there is no published price, no free tier and no trial: this is a sales conversation, an onboarding project and an annual commitment, which for a startup sending 50,000 emails a month is simply the wrong product.
What Retarus does well
- Own self-operated data centres rather than a hyperscaler underneath
- Processing location selectable per customer and written into the contract
- Certified Senders Alliance, plus documentation against HIPAA, SOX, PCI DSS and TISAX
- Guaranteed throughput rates, which matters when a queue costs money
- German company, 33 years in business, with an enterprise support organisation
Where Retarus falls short
- Data centres include the United States and APAC — European processing must be specified
- No published pricing, no free tier and no trial
- Sales-led onboarding rather than an API key and a card
- Overkill for anyone sending under a few million messages a month
Standout feature. It owns its data centres. In a category where almost everyone rents, Retarus lets you name the country your mail is processed in and holds the hardware that does it.
Amsterdam, Netherlands
Free 1,000 emails a month / Startup from $15 a month (50,000-100,000) at $0.30 per 1,000 / Growth from $80 a month up to 2.5M / Enterprise above that; dedicated IP $24.95 a month
Free 1,000 emails a month, no card, no time limit
Best for: Teams that want email, SMS and WhatsApp from one Amsterdam vendor and can live with a vague residency answer
Bird B.V. is at Keizersgracht 268 in Amsterdam, and its terms make that the contracting entity for every customer outside the United States, governed by Dutch law with jurisdiction in the Amsterdam courts.
The email API is generous at the entry point — 1,000 emails a month free with no card and no time limit — then $15 a month from the Startup tier at $0.30 per 1,000, $80 a month on Growth up to 2.5 million, and $24.95 a month for a dedicated IP.
The reason to choose it over a pure email service is the other channels. Email, SMS, WhatsApp and push sit on one platform with one contract, which for a product sending order updates across three channels removes a real amount of vendor management. The documentation exposes regional hosts, us1.platform.bird.com and eu1.platform.bird.com, so an EU endpoint demonstrably exists.
The residency answer is where it falls short of the top of this list.
Bird's privacy policy acknowledges that services may involve transferring personal data outside the EEA, does not name the hosting provider for email, and says only that all hosting providers meet ISO 27001 and SOC 2 Type II. Pricing is in US dollars, and US customers of the email product contract with Bird.com Inc. in Delaware rather than the Dutch entity — which tells you the email business has an American leg, even if yours does not touch it.
What Bird does well
- Bird B.V. in Amsterdam is the contracting party for all customers outside the US
- Free 1,000 emails a month with no card and no expiry
- Email, SMS, WhatsApp and push on one platform and one contract
- An EU regional endpoint is published in the documentation
- Dedicated IPs available at $24.95 a month
Where Bird falls short
- Does not state where email data is stored, and permits transfers outside the EEA
- The hosting provider for email is not named anywhere public
- Priced in US dollars, with a Delaware entity for US email customers
- A large platform with correspondingly heavy onboarding for a simple sending need
Standout feature. Three channels, one Dutch contract. The catch is that Bird is the only provider on this page that will not tell you where the mail is processed.
Torrelodones, Madrid, Spain
Free for 80,000 emails a month to 20,000 contacts; transactional email is an add-on at €14.95 a month after a 30-day trial; paid plans are priced from a volume slider rather than a published table
Free plan, plus a 30-day trial of the transactional module
Best for: Small senders who need a large free allowance more than they need a residency statement
Mailrelay gives away more email than anything else in this category: 80,000 messages a month to 20,000 contacts, on a free plan that includes the editor, automation, landing pages, segmentation, A/B testing, reporting and API access. For a small shop or a side project that number is not a trial, it is the whole requirement, and no other provider here comes close.
The operator is CPC Servicios Informáticos Aplicados a Nuevas Tecnologías SL, CIF B83964601, at C/ Nardo 12 in Torrelodones near Madrid. Transactional sending is available over SMTP or API and the vendor describes connecting a site, shop or app and letting Mailrelay handle delivery — the same infrastructure as the campaign side, which is why the free volume is so high.
Two things to know before counting on it. Transactional email is a paid add-on at €14.95 a month after a 30-day trial, so the headline free tier is a marketing allowance, not a transactional one; the same goes for WhatsApp campaigns at €9.95.
And Mailrelay does not publish where it hosts — the legal notice, the homepage and the pricing page name no data centre, no country and no subprocessor, which is why the residency field for this tool is empty rather than filled in with a guess.
What Mailrelay does well
- Free tier of 80,000 emails a month to 20,000 contacts, the largest here
- Spanish company with a published CIF and registered address near Madrid
- SMTP and API sending on the same platform as the campaigns
- Full feature set on the free plan, including automation and API access
Where Mailrelay falls short
- Does not publish a hosting location or a subprocessor list anywhere
- Transactional email is a €14.95 a month add-on, not part of the free tier
- Paid plans are priced from a slider rather than a published table
- No security certification stated
- A marketing platform first, with transactional sending attached
Standout feature. 80,000 free emails a month. Nothing else here is within an order of magnitude — but the transactional module is the part you have to pay for.
Gothenburg, Sweden
Founded 2010
Quote only, based on the number of users, domains and outgoing volume
None published
Best for: Large senders and operators who would rather run the sending platform than rent one
Halon Security AB, at Lilla Bommen 3 in Gothenburg, sells email infrastructure rather than email delivery. Halon Engage is a programmable MTA for senders: the queueing, routing and policy layer that a SaaS provider would keep for itself, handed to you with a scripting language so delivery decisions — per-destination throttling, retry logic, signing, routing rules — are code you write rather than settings you request.
That inverts the residency question instead of answering it. There is no processing location to assess because you choose the machines and the country; there is no subprocessor list because there is no subprocessor.
For an operator already running its own IP space and abuse desk, or a telco or ESP building a product on top, that is the correct shape, and the Swedish company behind it has been at it since 2010 with offices in Gothenburg, Berlin and San Francisco.
It is also the most demanding option on this page by a wide margin. Pricing is a quote based on users, domains and outgoing volume, with no free version and no trial published. You supply the IPs, the warm-up, the feedback loop registrations, the monitoring and the person who reads bounce logs. For a team that wants to send a password reset from an application, this is not the product.
What Halon does well
- A programmable MTA: delivery policy is code, not a support ticket
- Runs wherever you deploy it, so residency is entirely your decision
- No subprocessors, because there is no hosted service in the path
- Swedish company operating since 2010, with a European support presence
Where Halon falls short
- Not a sending service — you still need IPs, warm-up and an abuse desk
- Quote-only pricing with no free version or published trial
- Requires in-house email operations expertise to be worth anything
- Wildly oversized for anyone sending under a few million messages a month
Standout feature. It removes the provider from the question rather than replacing it. At large volume that is the only version of sovereignty nobody can revise in a pricing update.
Offenbach am Main, Germany
No public price list; pricing on request through a form
30-day free trial
Best for: German-speaking marketing teams that want campaigns and an SMTP API from one vendor
Maileon is operated by XQueue GmbH at Christian-Pleß-Straße 11-13 in Offenbach am Main, registered as HRB 12442, with a second office in Freiburg. The platform pairs campaign management with an SMTP and email API, so transactional mail and marketing mail share one system, one template library and one sender reputation — the same logic as Inxmail, at a smaller scale and with a lighter footprint.
The certification story is reasonable: XQueue publishes an ISO 27001 certificate in its own name, and the company states Certified Senders Alliance, eco and ISPA credentials, which is the German trio that matters for inbox placement at GMX and Web.de. A 30-day free trial is offered without a sales call.
What keeps it at the bottom of this list is what is missing from the public record. Maileon publishes no price list — pricing comes from a form — and states no hosting location anywhere on its site.
It markets itself as a European platform, and the company is unambiguously German, but the country the servers are in is not something a buyer can establish without asking. For a directory that treats hosting location as the point, that omission costs it places.
What Maileon does well
- German company with a public register entry and an ISO 27001 certificate
- Certified Senders Alliance, eco and ISPA credentials for German inbox placement
- SMTP and email API alongside full campaign management
- 30-day free trial with no sales call required
Where Maileon falls short
- States no hosting location anywhere on its own site
- No published price list — every price comes from a form
- Marketing platform first, with transactional sending as a component
- Oriented to German-speaking markets in interface and support
Standout feature. A German entity with a named ISO 27001 certificate — and no published answer to where it hosts, which is the one question this category exists to ask.
