đź“§ Problems Sending Emails

If you're experiencing issues sending emails, you may notice one or more of the following behaviors:

  • Emails fail to send entirely

  • Emails stay stuck in your Drafts folder
  • An error message appears when attempting to send an email

You may also experience other unwanted behavior, but these are the most common issues that he hear about. However, before you reach out to our support team, we recommend following some of the quick fixes below.

🛠️ Suggested Fixes

This issue is most commonly caused by incorrect SMTP server settings, or interference by your firewall or antivirus software. Follow these steps to try and troubleshoot the issue:

  1. Check Webmail Access

    • Log into your email via your provider’s webmail portal (e.g., gmail.com).

    • Try sending an email from there.

    • If you cannot send emails, the issue likely lies with your email provider — please contact them directly.

    • If you are able to send emails, continue with the steps below.

  2. Temporarily Disable Security Software

    • Try sending an email after disabling your firewall, antivirus, or proxy (if applicable).

    • Be sure to whitelist Mailbird in any security software you're  to prevent future conflicts.

  3. Test Your Connection in Mailbird

    • Click the Mailbird menu in the top-left corner (three horizontal lines).

    • Go to Settings > Identities.

    • Double-click the affected email account and select Test Connection.

    • Review any error message that appears, as it can help identify the issue.

  4. Verify Outgoing Server (SMTP) Settings

    • Search Google for your provider’s recommended SMTP settings (e.g., "Yahoo SMTP server settings").

    • In Mailbird, navigate to the Identities tab as described above.

    • Compare the settings in Mailbird with the recommended ones.

    • If there's a mismatch, update your settings accordingly.
