Support » Plugin: WP Mail SMTP by WPForms » Multisite not sending emails

    My website is not sending mails recently. I installed the Newsletter plugin and send over 3000 mails to subscribers. i believe the issue started after that. I have uninstalled the plugin but when i test mail with Wp Mail SMTP, i get the error message;

    There was a problem while sending the test email.

    Error due to unsolicited and/or bulk e-mail.

    This means the connection to your SMTP host was made successfully, but the host rejected the email.

    Typically this error is returned when you are sending too many e-mails or e-mails that have been identified as spam.

    Can you help me fix this please?

    Hi Coach,

    It seems you are using “Other SMTP” mailer and SMTP host is either Gmail or Outlook (or similar email provider that have an inbox). Those providers do not like a ton of emails sent through them in a short period of time.

    When you want to send emails in bulk, as you did with 3000 subscribers, I strongly encourage you to start using specialized transactional services, like Mailgun or Sendgrid.

    Read our Mailgun or SendGrid documentation for more details.

    I hope this helps!
