If your email stops working, there are several things you can try to fix the problem:

1. Check your internet connection: Make sure your device is connected to the internet and that there are no issues with your wifi or broadband connection.

2. Restart your device: Sometimes, simply restarting your device can resolve any issues with your email.

3. Check your email account settings: Make sure that your email account settings are correct, including the incoming and outgoing server names, port numbers, and any security settings.

4. Check for updates: Make sure you have the latest version of your email client and any relevant software or operating system updates.

5. Check for maintenance or outages: It's possible that your email provider is experiencing maintenance or an outage, which could be causing the issue. Check the provider's website or social media accounts for any announcements.

If these steps don't fix the problem, you may need to contact your email provider or seek technical assistance. It's also a good idea to make sure you have a backup of any important emails or data in case there is a problem with your account.
