Not Sending Emails!

@mannuforall,

I presume your blog is creating new content each hour so there is something to send.

Have you tried the things suggested here:
https://subscribe2.wordpress.com/2013/09/17/troubleshooting-emails-in-subscribe2/

Yes, I’m continuously posting new contents and there’s no issue few days back with same settings.
It stopped suddenly.

@mannuforall,

Okay, so that answered the new content question. Have you worked through the trouble shooting tips?

These things always stop working suddenly – usually because something changes on the server – a new plugin, an update, a lot of new subscribers or your hosting provider changing something.

Yes, all looking fine.
But now suddenly Resend Digest option start to work!

@mannuforall,

I think you should install the email logging plugin suggested on that page and keep and eye on what gets logged. If emails are logged but never arrive then they are being blocked on the server. If they don’t get logged then they are not being generated so it may be a configuration issue with Subscribe2.
