Hi,
we use Mailpoet for newsletter. Today, in the middle of the sending process, Mailpoet stopped and showed an error message.
the PHP version has already been upgraded and the message that there are too many subscribers cannot be correct. There are currently 118 and 1000 are free.
An account has now been created at mailpoet, but it didn’t help. So we don’t know exactly why Mailpoet stopped sending.
what are we overlooking and what have we done wrong?
