It has stopped sending newsletters as well.
I am now at about 500 subscribers and deleted the rest.
I have tried various options under Send With..
In the past I used smtp.sendgrid.net I just sent a Test Mail and it did not send a test mail.
Then I tried PHP Mail. Test via Send Test mail. Nothing.
I think I may have found the problem. It has possibly to do with https://en.wikipedia.org/wiki/DMARC
Did you manage to resolve? I have a similar issue
I spoke to my host.
He suggested I delete the DMARC until I have exhausted all other possibilities.
This is some of what he said:
You could switch back to PHP Mail, but that won’t help – we don’t support DKIM for mail sent from our servers, you’ll be just using SPF as you are with Sendgrid right now. My guess is that may be fine, typically once the more aggressive SPF record is in place spoofing issues largely go away.
We have set the SPF record more aggressive.
As you can see I am using sendgrid. That was not part of my SPF.
He also suggested SPF be changed to -all instead of ~all
Now…if this is greek to you then we are in the same greek boat.
I did what he said and now I can send.
The other obvious issue was I had more than 8000 subscribers.
Mailpoet will not send if you have more than 2000 subs.
I deleted the pro – part of MailPoet.
I deleted them as I only send emails to about 300.
Ok thanks, I will start with my host

I have fixed my issue
Downloaded WP Rollback addin and rolled back mailpoet to v2.7.6. Everything works just as it was.
NOTE rolling back to 2.7.7 didn’t work!
Hope this helps other people 🙂
When you roll back to version 2.7.6 you are using the MailPoet version that still came with our implementation of the PHPMailer library. Newer versions use the PHPMailer that comes with WordPress.
ok, I don’t know if that is a good thing or not, but something has gone wrong in the latest release and this was the simplest way to resolve. I don’t know enough coding to start editing single files
