Many Mac users rely on the Mail app for daily communication, but what happens when it suddenly stops sending emails? It’s a frustrating problem that can disrupt your workflow. Fortunately, there are several fixes you can try to get your Mail app back up and running. Here are the seven best fixes for when you can’t send emails using the Mail app on Mac.

1. Check Your Internet Connection

The first thing to do is ensure your internet connection is stable. A simple way to test this is by using a browser to see if you can access websites. If your internet is down, resetting your router or contacting your ISP may be necessary.

2. Verify SMTP Settings

Incorrect SMTP (Simple Mail Transfer Protocol) settings are a common cause of email sending issues. Check these settings in the Mail app under “Preferences” > “Accounts” > “Server Settings” to ensure they match those provided by your email service provider.

3. Update Your Email Password

If you’ve recently changed your email password through the web portal or other means, you’ll also need to update it in the Mail app. Go to “Preferences” > “Accounts” and select the account that’s experiencing issues. Update the password and try sending an email again.

4. Ensure ‘Outgoing Mail Server’ Is Online

Sometimes, the outgoing mail server might be offline or having issues. In the Mail app, check under “Window” > “Connection Doctor” to see if there are any red indicators next to your outgoing mail server (SMTP).

5. Test With Another Email Account

To determine if the problem is with your email account or the Mail app itself, try adding another email account and sending a message. If it works with a different account, there might be an issue with your primary email service provider.

6. Delete and Read Add Account

If none of the above steps work, try deleting and re-adding your email account in the Mail app. This can often resolve persistent issues tied to account configurations or corrupted files.

7. Update macOS

Like all software, ensuring that your system is up-to-date is crucial for smooth operation. Go to “System Preferences” > “Software Update” and install any available updates for macOS, which could include bug fixes for the Mail app.

If these fixes don’t resolve your issue with sending emails from the Mac Mail app, it may be time to contact Apple Support or consult directly with your email service provider for further assistance.
