Detailed Review
Boost My Mail manages signatures for Outlook and Gmail users. The legal notice names Boost My Mail, SIREN 835398272, with its registered office at 10 boulevard du Zenith, 44800 Saint-Herblain. The French company register shows it created on 9 February 2018 as an SAS whose president is A5 Groupe.
Against WiseStamp, it offers a plain two-plan structure and a French sovereignty argument, with the site available in French and English.
Plans and features
The Basic plan is described as the essentials to harmonise signatures with unlimited signatures and no banners. The Premium plan adds unlimited banners. Both plans include directory sync for Microsoft, Google and Lucca, dynamic segmentation of staff, a template library, multi-company and multi-signature support, a customisable CTA button, lighter signatures, self-service and disclaimers.
Hosting and security
The vendor says it relies on a French sovereign host meeting the HDS standard, and also benefits from Azure's ISO 27001 and ISO 20000 standards. It says emails are never stored on its servers. The legal notice says the site is hosted on Microsoft Azure.
Pricing
No prices are published. The pricing page offers a demo, a brochure and a free test of each plan.
Limitations to Consider
No public prices. Ownership beyond the French holding that presides the SAS was not checked. Documentation and testimonials are mostly in French.
