Zagomail

This used to be a great software when I first bought it, I actually just upgraded tiers to increase subaccount limits. My clients loved it, I loved it... and then POOF error messages across the board. No emails can be sent from the software (so no campaigns, no test emails, no user signups, etc..). Support is almost entirely unresponsive via chat bot and email. I say "almost" because I actually did get the following email from them (after over a week of radio silence):
"Hi there,
We 're experiencing some outage on sending, our team is working to fix it and we will update you once done. Sorry for any inconvenience.
Michael
Zagomail"

However, I've heard nothing since...
