Pros / Cons
  • Simple UI - The dashboard and interface are straightforward to navigate, making it easy for developers.
  • You can connect your email flow either through their API... or the old school SMTP, which enables you to send through any software on the market that supports an external integration.

  • An excellent service that despite the somewhat difficult initial curve in understanding all the functions and how to get the most out of it then really becomes a well-structured service with all the necessary functions to control and manage the sending of e-mails.
  • I wasn't able to completely refactor the integration before the cutoff, so now I have no automation and they deleted all my contacts and my templates, so I get to rebuild ALL of that from scratch.
