    Greetings!

    I’m getting an email delivery error from WP Mail SMTP and I was hoping you could point me in the right direction.

    Mailer: Gmail
{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "invalidArgument",
    "message": "Invalid To header"
   }
  ],
  "code": 400,
  "message": "Invalid To header"
 }
}

    This is being generated after attempting to send an email using a volunteer management app. Please let me know what additional information I can provide or troubleshooting I can do.

    Thank you!

  • Hi @andreainblue,

    The error indicates you’re sending emails with an improperly formatted header. The plugin might have added additional To header to send the email and is not correctly formatted. To troubleshoot, please provide the header of the email your volunteer management app is sending.

    Thanks!

    Thanks very much for your response!

    I think we figured out the issue. The volunteer management app had a setting that we tweaked an all is well.
