I recently purchased this deal for mainly transactional mails SMTP/API. As I am familiar with email deliverability, I tested this solution and checked for blacklisted IP-addresses.

The interface is clean and user-friendly. Thumbs up for George (aka Jiří Žižka 🙂) and team for this. Note, this tool is not really built for marketing mails (if email marketing is new for you). It's main focus is serving as a mail server. And I hope it will keep this focus. Keeping IP's clean as an ESP for marketing purposes is not easy (e.g. users 'forget" list validation, ramping up volumes, … and that makes maintaining a good sending reputation difficult). Having the ability to send out straightforward 'marketing mails' is a nice functionality, however.

If you start using this tool (and act as a reliable sender = no cold mails, no bounces, handling volumes correctly, …) you can (if approved for good practice) switch from the onboarding IP's to the clean IP's of Emailit. George takes care of that and my tests proved these IP's are good quality (none blacklisted, fast, …). I also believe/hope this is constantly monitored.

Also note that well-known transactional mail servers also use onboarding IP's (that might be blacklisted due to free accounts that abuse these offerings). This is how it should be done. Therefore, I appreciate this AppSumo offer I purchased. I like to suggest you to do the same if you need an emailing platform and your intentions are good.
