- Try sorting messages in the message list by Date or another attribute, or searching for messages, to verify if you received them.
- Check whether your account is offline or disabled (inactive).
- If you’re missing emails from a specific person or group, check whether you blocked messages from them.
- Try quitting Mail, then opening it again.
- Choose Window > Connection Doctor, then follow any instructions in the Details column. Check for problems logging in to email accounts or with the incoming mail server, or with firewall software blocking network traffic.Check whether you’re affected by another firewall, such as software installed separately from macOS or built into an internet sharing router, or administered by your email account provider. Contact the appropriate person for information.
- If you’re still having problems, contact your email account provider to verify your user name, password, incoming mail server, and other required information. Then verify the information is entered correctly in Mail account preferences.
If you’re logged in to a network using VPN, also make sure that you entered your VPN password correctly.

If your Mac is connected to the Internet but suddenly stops sending email, you should generally try again later, and if necessary work with your email provider to resolve. If you're using Apple's iCloud Mail, learn how to resolve issues with iCloud Mail.
Check for status messages
You might see a status icon such as a lightning bolt or warning symbol next to your account's inbox in the Mail sidebar, or in the upper-right corner of the Mail window. Click it to learn more.
- If the status is Network Offline, make sure that your Mac is connected to the Internet, then try again.
- If the status is Login Failed, check with your email provider to be sure that your account is set up correctly on your Mac.
- If Mail asks for your password, but entering the password doesn't help, find out why your email provider is rejecting your password.
- If your email service is temporarily unavailable, your email provider might have a status message on their website. For example, Apple's system status page shows the status of iCloud Mail. Status pages are also available for other email services, such as Gmail and Outlook. Some brief service outages might not appear on a system status page, so you might want to wait a few hours and try again.

Webmail is a good way to verify that your account is valid and you can sign in to it from the web, but it doesn't mean that your account is set up correctly in Mail. Your email provider can help you verify your email settings and check for other issues that affect sending or receiving email.
