If your MailPoet subscription form isn’t sending confirmation emails, it’s often due to configuration issues or server-related restrictions. MailPoet relies on proper email setup to deliver those emails, especially for double opt-in (confirmation) processes.

✅ Common Reasons & Solutions:

🔹 1. Double Opt-In Not Enabled or Misconfigured

Problem: The form might not be set to send a confirmation email.
Solution:

• Go to MailPoet → Forms

• Edit your form and check if “Send a confirmation email” is enabled

• Also ensure you’ve selected a confirmation email template

🔹 2. Wrong Sending Method Configuration

Problem: If MailPoet is not properly set up to send emails, confirmation mails will fail.
Solution:

• Go to MailPoet → Settings → Send With

• Choose MailPoet Sending Service (recommended) or set up a reliable SMTP

• Test email sending from MailPoet → Emails → Send Test Email

🔹 3. Domain Not Verified with MailPoet Sending Service

Problem: If you’re using MailPoet’s own sending service, your domain may need verification.
Solution:

• Go to MailPoet Account Dashboard and follow domain verification instructions

• This ensures better deliverability and avoids spam filters

🔹 4. Plugin Conflict or JavaScript Errors

Problem: Another plugin or theme may be conflicting with form submission.
Solution:

• Use browser developer tools to check for JavaScript errors

• Disable other plugins temporarily and switch to a default theme (like Twenty Twenty-Four) to test

If you’re still facing issues, MailPoet has excellent support and documentation to help you troubleshoot further.
