Messages Not Sending on Mac

When you rely heavily on your inbox to get work done, you can’t afford to get emails stuck in the outbox on your Mac.

Before you start troubleshooting, check if your internet connection is stable or if you’re accidentally on airplane mode (yes, that happens). If after you’ve done that and you still can’t send a message from your Mail app, then try the solution below:

Solution 1: Check the Mail Server

Taking a look at your Mail server can be a helpful solution if you’re having issues sending messages on mail.

Sometimes when your Mail server is affecting your Mail app it will send you an alert and sometimes it won’t. So you’ll have to see if the Mail server is configured correctly.

1. Make sure the one you have on your Mac is the same that your email provider gave you.

2. Go to Mail > Preferences.

3. Pick your account, press Server Settings, then Edit SMTP Server List.

4. See if the server info corresponds to the one expected. If it does not, you might need to contact your email provider.

Solution 2: Check Your Mail Connections

Cyber security is essential, but your laptop’s firewall software can sometimes cause issues with your Mail app connection and email provider configuration.

If you’re unsure if your firewall might be the culprit follow these steps to find out if this is the reason you can send out emails:

1. Go to Connection Doctor and check if there are any firewall problems, especially on ports 25, 465, or 587.

2. If there are, again you should contact your email provider and probably reconfigure the server settings.

Last Fix:

Don’t forget to do some basic troubleshooting that might help to prevent this issue from happening:

  • Making sure that your Mac is connect to the interest
  • Try to load a page in Safari or another browser to see if the issue is the app
  • Check that the date and time is set correctly on your Mac.

Lastly, make sure that you enter the correct phone number or email address for the contact, if the email address is missing a number or letter it’ll either end up going to the wrong person or not be sent at all.

Mac Mail Not Receiving Emails

Nothing is more suspicious than an empty inbox.

If your inbox is usually buzzing you should be worried that your Mac Mail app isn’t receiving your daily dose of emails.
We’ve found a solution that can help. But before you start be sure to check your Connection Doctor to see what problems might be preventing your Mail app from receiving emails.

  • Or choose View > Filter > Enable Message Filter.

If your filters aren’t the issue, you’ll need to check if you’ve blocked senders on your Mail app and unblock them with the two easy steps:

2. Move the pointer next to their name in the message header, click the arrow, then choose Unblock Contact.
