WP Mail SMTP stopped sending emails

Hi @cakers82,

If it was working previously, you might have changed the password which needs to be updated here as well. Your server might have disabled outgoing SMTP connections. On some mail servers, SSL/TLS support may not be enabled or the existing SSL certificate may have expired. You’ll need to get in touch with your hosting provider to find the specific reason for the failing connection.

I hope this helps!

Same issue here with Gmail. Password and email ok.
Could not authenticate your SMTP account.

Hi @billygunn111,

I’m sorry you’re still seeing issues. I’m not sure from your response here, what all you’ve tried — could you please let us know if you’ve reached out to your site’s hosting provider?

Or if you’d prefer, you could try switching to a different mailer. The Other SMTP mailer relies on your hosting provider correctly setting things up on their server — and will run into errors when that’s not the case. However, many of our other mailer options do not rely so heavily on your server’s configuration details.

Specifically, I’d recommend checking out Pepipost, SendGrid, Mailgun, or Sendinblue. The setups for these will require a bit of time initially, but ultimately will be much more reliable. You can find an overview of all options here (and links to full setup tutorials).

I hope this helps!

Changing the password in Gmail fixed the issue for me. I had to reset it even thought I could still login. I use a gmail noreply generic email for several sites and I might nee to explore these Pepipost, SendGrid, Mailgun, or Sendinblue

As it is proven to be a pain. Any recommendations as to the easiest one to setup and most reliable would be great. thanks

Hi @billygunn111,

I’ve set up each of these mailers, and in my opinion they all require about equal effort. While the interfaces each look different, the general steps are pretty much the same. And because they work in such similar ways, they’re also all equally reliable from my experience.

You will need a site-specific From Email for these services to be most effective (ie, [email protected]). This is important because all of these services use your site’s domain as key part of making sure your emails deliver — and so your From Email should match that domain, too.

If you don’t have any particular preference right now, then what I’d recommend is checking out the free plans on each, as well as the pricing for the next step up in case you need it (either now or later), and using that to guide your choice.

We’ve covered all free plan limits in our Complete Guide to WP Mail SMTP Mailers, so you don’t have to dig around each site for that information.

I hope this helps you out!
