Mailtastic is an email signature marketing tool, that aims to turn employees email signatures into a strong, measurable marketing effort. Mailtastic is a Cognism brand.
I would recommend it for anyone who bases their initial setup on Microsoft 365 environment as it is the easiest way to manage licences and users. It is intuitive to set up and use, signatures appear instantly, campaign updates are live, and metrics can be nicely reported. There are not so many points that one can complain about in regards to Mailtastic, maybe some OS or platforms have lack of support, but that is it.
Great tool to use in every aspect. There are apps for PC and Mac OS, extensions for Outlook, online versions support. There are tons of materials and FAQs on how to Mailtastic setup for a platform or environment. It takes off a lot of time from administrator of the product as users can connect themselves to this system.
