    Hey,

    Can anyone help identify what is causing this issue:

    cURL error 18: transfer closed with 76 bytes remaining to read
    Please review your WP Mail SMTP settings in plugin admin area. Consider running an email test after fixing it.

    We seem to be getting it quite often and causing emails to not be sent out.

    Thanks

    Hi @damiansmith86,

    The error indicates it’s an issue with the curl in your server and nothing specific to the plugin. You might need to consult your hosting provider about this curl error.

    Alternatively, if your host is unable to fix this issue for you, you might consider switching to a different mailer option, preferably API based. In some cases, we find that only a specific mailer will run into issues on a site, whereas other options will work just fine. In case it helps, here’s our tutorial on setting up every available mailer.

    I hope this helps!

    Hi @damiansmith86 – We haven’t heard from you in about a week, so I’m going to go ahead and mark this ticket resolved. If you still have questions, though, please feel welcome to continue the conversation.
