Hi, I was using fluent SMTP, and that was working fine. Actually some good guy form this sub suggested me that to send email using my google workspace mail. But suddently today I saw that the email is not working. Then I checked and got “Token has been expired or revoked.” error message. then I tried to put new gmail api credentials and nothing works. I tried to use WP Mail SMTP, and same problem.
I wasn’t sending mass email, just some form submission mail that’s it. can anyone please tell me what is happening?

I’ve had similar issues trying to send mail via gmail. I would use SendGrid (or some other transactional email service) instead. With a free SendGrid account, you can send 100 emails/day and it should integrate with the FluentSMTP plugin (or WP Mail SMTP).
