This product worked well in the beginning. Then all of the sudden it stopped working and support disappeared. The software is supposed to send 40 emails per day to warm my address, but the data is showing that it sends about 5 or so. I also get littered with junk emails now.

The interface looks pretty clean and easy to get started. The SMTP and Gmail set-up is quite easy almost no learning curve is needed. The support doc is short but clear.

Mailwarm has the simplest UX. Just connect your email address and it does the rest. I like to keep my list warmed up in between large sends and mailwarm makes sure all my emails land in the inbox
