Sending paused

Hi, i sent my first newsletter to approx. 200 subscribers (imported from previous plugin) and I received Sending paused e-mail due to an unusually high delivery issue rate. I only had 2 bounces. In my mailpoet account I saw that only 157 e-mails were sent.

I don’t use any automated e-mails. In my wp plugin I received an error message in the top bar and I clicked “Resume sending”, but new user can’t subscribe nor I can’t maunally resent confirmation e-mail due to “There was a problem with your sending method. Please check if your sending method is properly configured.”.
