Hi Joel,
700 Notifications receive the following error
You’re probably hitting the Google limits, which are 500 emails in a day. See this guide: https://support.google.com/mail/answer/22839?hl=en#zippy=%2Cyou-have-reached-a-limit-for-sending-mail
I’d suggest switching to another email provider which has higher limits. And if you’re sensing these 700 emails at once, SMTP is not a good solution, because each email has to open a separate connection. If that’s the case I’d suggest switching to SendGrid or Mailgun and user their API instead of SMTP.
I have checked with Google support, and they confirmed that I am not hitting any limits. I have workspace account access to support. I also checked the metrics on google and I did not receive the warning email google says I should receive. I am using the API access built in WP Mail SMTP
I know there are many commercial services that would make this easier, but I am trying to stay as light as possible on services. PHP and WordPress versions are both in line with stated compatibility.
Please consider other possible issues.
I see, thanks for coming back to me with more details!
Our plugin only uses the wp_mail() function, we’re not establishing any connection on our own. So whatever is in control of the email submission is handling all the traffic.
I think you should reach out to WP Mail SMTP support in this case.
