Have you received an email saying that your email account is almost full? (See image below as reference)
You will have 3 options:
- Change your Email Quota (if not already selected as unlimited). See Instructions
- Upgrade your Hosting package to increase your storage limit. See Instructions
- Sign into your Webmail account and delete emails to clear up storage space. See Instructions
Please note that if you are running IMAP settings, then deleting emails from the server, will delete emails from all your devices too. If you are running POP, then deleting emails from the server will have no effect on your devices.
