🖐 Hey, I work on ⁠— an email service that you should know about.

Suuuuuuuper nervous to see Sidemail here on Betalist after 2 years of pouring my heart, all my focus & energy into building it together with my better half @kvrbova. Let me know what you think!

@Hanseflats Glad you like it! We sent emails through AWS (with our own dedicated IPs) + we have our own custom & lighting-fast mail server as a backup. Ultimately, we try to do as much as we can in-house.

If you mean sending cold emails, then no, that's not allowed. Better to find some tool that was built exactly for that use-case. is designed for sending emails to your users & subscribers who opted in.
@pkrupar Thanks Patrik! Mind if I ask where you set up that mail server? I'm looking into setting up my own.
