succesfully connected with G Suite, but email is not sending

@nera13

Unfortunately, that message means, that you are connected, but doesn’t mean that email will be sent successfully ??

Please upgrade to 1.2.0 and re-run the Email Test. You will see the much more useful output. If that text doesn’t help you to identify the problem – please post it back here in this topic.

I’ve updated, here is the output:

@nera13

You have created a project, but have not enabled the Gmail API usage for it.

If it is recently created, enable Gmail API by visiting https://console.developers.google.com/apis/api/gmail.googleapis.com/overview?project=336025175257 then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.

Thanks, it worked, but I still can’t send messages from contact form 7. I’m using the same email, email is in inotechas.com domain, it can be the problem?

@nera13

What is the From email address in CF7 plugin? Try make them the same: From Email in WP Mail SMTP settings and From Email in Contact Form 7 form.

email is the same in both places

Email Test works correctly, right? Are emails sending while testing and coming to your inbox?

You can check whether the email has come through Google servers:
in Console for Gmail API – there will be a number of requests done in the last 1 hour. You should check the number before and after the order (that generates emails). Here is a screenshot of highlighted areas: https://cloud.supportally.com/oXiZ
Note: it may take several minutes before data will appear there on a graph.

If you see before – 0, and after – 2 (or how many emails your site is sending on a form submission). That means that Google received emails and actually sent them. That will mean the problem is in your inbox (full, rejecting, spam, filters, forwarding, archiving etc).

If the number is not increased after 5-10 minutes – Google is not even receiving anything. That will be harder to debug.
