It's definitely improved since I first tried it ~6 years ago, is almost identical to TypeApp but, has been a bit more reliable. Until today, when it suddenly stopped connecting to all of my email providers. It won't sync or send emails, the "help" section is useless for REAL issues like this. Even restarted my phone, didn't fix it. Internet works fine. I'm getting a couple of errors, they disappear fast so the only 1 I can provide is "Failed to send some messages - SMTP response is 0 length"
