Emails getting missed

Hi Barry,

Please could you share your Post SMTP diagnostics log with us? Just paste it in your reply here. That will be a big help in helping us to pin down a possible issue.

Kind Regards,
Tim

Hi Barry,

Thanks for the log. That all looks fairly normal. Please could you have a look in the email log and see what error is being recorded for failed emails?

Kind Regards,
Tim

Hi Barry,

That is very unusual – if an email send has been attempted in any way, Post SMTP almost always records this. I can’t see any plugins that are likely to cause a conflict, but it’s a possbility.

I presume you can’t think of any changes you made to the site around the same time as this issue cropped up?

If you send a test mail from Post SMTP, is it always logged and sent? It’s worth trying that too.

Kind Regards,
Tim

Hi @zimmo,

Yep, totally understand that – frustrating! It’s interesting that it’s only happening in WooCommerce too. I presume things like contact forms are all working fine?

I agree that it is unlikely to be Gmail at fault, it should indeed still appear in the email log as you said.

All other plugins and WP core up-to-date?

Kind Regards,
Tim

Just to let you know:

i just had the same problem today. But not with WooCommerce emails but from https://ww.wp.xz.cn/plugins/ameliabooking/ – paid Version.

The booking is saved in the Database / Event from WP Amelia, but no Mail was send to the customer and also not the copy we get… Even the Conversion in Google Analytics was triggered correct.

BUT no error / mention of the Booking in Post SMTP Log.

Yesterday the Mails got send for 2 Bookings and also when i just tested a booking the Mails got send also the Post SMTP Test is successfull and mail from Elementor Contatc Forms.

Strange.
