Detailed Review
Syvel is a trade name of RCQD Labs, a French sole trader (micro-entreprise) with SIRET 10225373900019. The terms and the general sales terms are governed by French law, and French courts are competent. The sales terms list Scaleway SAS in France for application servers and the database.
The service is aimed at developers. It analyses domains through live DNS data such as MX records, SPF, DMARC and domain age, and returns a risk score between 0 and 100.
What the API checks
The home page lists typo detection, role addresses and disposable domains in one API call, and claims response times under 50 ms and 99.9% uptime. The service describes itself as a detection of fraudulent domains, with 100,000 domains indexed. It uses a Domain check and a privacy mode that hashes the address.
Plans in euros
The free plan has 100 requests a month and 24 hours of log retention. Starter costs EUR 9 for 1,000 requests, Pro EUR 49 for 10,000 and Business EUR 199 for 100,000, with log retention of 30, 60 and 90 days. Prices are excluding VAT.
Compared with ZeroBounce
Syvel is a sign-up filter, not a bulk list cleaner. The pages we read describe domain-level analysis, and we found no mailbox-level SMTP check or bulk upload. ZeroBounce covers both, so Syvel replaces only the real-time part.
Limitations to Consider
The operator is a sole trader, so continuity and liability differ from a limited company. The pages read describe domain analysis and do not show a mailbox-level SMTP check or bulk list upload. The site uses Google Analytics, and statements such as CLOUD Act-proof are the vendor's own marketing claims.
Who Should Use Syvel
Developers and SaaS teams that need to stop disposable sign-ups with data kept in France. For bulk list cleaning use Bouncer.
