🚫 Problems Sending Emails in Mailbird Next

If you're unable to send emails in Mailbird Next, you might notice one or more of the following symptoms:

• Emails fail to send entirely.

• Emails stay stuck in your Drafts folder.

• You receive an error message when trying to send.

Other variations of this issue can also occur. Before contacting our team, we strongly recommend trying the following quick and easy fixes.

✅ First confirm whether the message was actually sent

Occasionally, a sending issue can look misleading. For example, an email may appear in Sent but still show a Draft label, remain visible in Drafts, or look like it has both a sent copy and a draft copy.

Before deleting or sending the email again, please check the following:

1. Sign in to your email provider’s webmail and check the Sent folder there.
2. If the email is present in webmail Sent, or the recipient has confirmed receiving it, avoid resending it. The remaining Draft label or duplicate draft is usually a local draft/sync state that did not clear correctly.
3. Restart Mailbird Next, then re-check the affected Sent and Drafts folders.
4. If the sent copy is correct but a duplicate draft remains, remove only that duplicate draft after copying its contents somewhere safe if needed.
5. If the email is only in Drafts and does not appear in webmail Sent, treat it as not sent and continue with the SMTP troubleshooting steps below.

🔧 How to Fix Email Sending Issues

These problems are most often caused by firewall or antivirus interference, or incorrect SMTP settings. Follow these steps to troubleshoot:

🛡️ 1. Check Firewall, Antivirus, or Proxy Settings

• Temporarily disable your firewall, antivirus, or proxy (if applicable) and try sending an email again.

• Add Mailbird Next to the whitelist of any security software you're using on your computer.

💡 If you're not sure how to whitelist an app in your security software, then please contact your provider directly to receive the correct instructions.

🌐 2. Test Your Email via Webmail

• Log into your email account using your web browser (e.g., gmail.com, outlook.com).

• Try sending an email from there and see what happens.

There can be two outcomes:

1. If you can’t send an email while sending it through webmail, then the issue lies with your email provider. Please contact them directly.
2. If you can send emails successfully via webmail, please continue with the steps below.

📤 3. Verify SMTP (Outgoing Server) Settings

1. Search for your provider’s SMTP settings using our Mail Settings page.

2. In Mailbird Next, click the Settings icon (⚙️) in the left-hand panel.

3. Click on the Accounts tab at the top.

4. Select the account experiencing the issue from the left-side list.

5. Click Settings in the middle panel.

6. Under Outgoing server settings, check that the:

   • Server name matches the one listed on our Mail Settings page.

   • Port number matches the one listed on  our Mail Settings page.

   • Encryption type matches the one listed on our Mail Settings page.

If anything doesn't match, update the settings manually and enter the correct information.
