The iPhone mail app is a convenient service for sending and receiving your mail. You can have multiple accounts on the app, and it supports a range of email domains. But Mail is one of the annoying iPhone apps that won’t update automatically, which can be very frustrating.

In order to send and receive mail using the app, you must have a working internet connection. Check that your internet is working. Try using something that requires the internet – e.g. a YouTube video. If it doesn’t work, then there’s probably something wrong with your internet connection.

Try disconnecting and reconnecting to your network on your device, and try using the internet again.

If it still doesn’t work, try turning your router on and off again.

If it the issue persists, then you can check if there are any problems with your internet provider by going on https://downdetector.co.uk/ and searching for your broadband. Click on your broadband to see their recent outage reports in the last 24 hours. If there’s a high amount of reports, then there your internet broadband is having problems.
