    1

    Check your internet connection first

    ~16s
    Open a web browser and try to load any website (try google.com). If the page doesn't load, your internet is down and that is why email isn't working. Restart your router (unplug it for 60 seconds, then plug it back in) and try again in 2 minutes.
    2

    Try opening email in a web browser

    ~24s
    If you normally use an email app (the Mail app on iPhone, the Gmail app, Outlook app), try opening your email in a web browser instead. On a computer, go to gmail.com, yahoo.com, or outlook.com. If email works in the browser but not in the app, the problem is the app — not your account.

    Quick Tip

    This is a quick way to determine whether the problem is your app or your account.

    3

    Sign out and sign back in

    ~18s
    In your email app or on the website, sign out of your account. Then sign back in with your email address and password. If you have forgotten your password, most email services have a 'Forgot password' link on the sign-in page that will send a reset code to your phone number.
    4

    Check your storage

    ~28s
    Gmail accounts have 15 GB of free storage shared across Gmail, Google Drive, and Google Photos. If it is full, new emails will bounce back. To check: open Gmail in a browser, scroll to the very bottom of the page, and look for the storage indicator. If it shows something like '14.8 of 15 GB used,' you need to delete some old emails or attachments.

    Quick Tip

    Emails with large photo or video attachments take up the most space. Search for emails with attachments to find the big ones quickly.

    5

    Check if the email service is having an outage

    ~18s
    Sometimes Gmail, Yahoo, or Outlook experiences a temporary service disruption. Visit downdetector.com and search for 'Gmail,' 'Yahoo Mail,' or 'Outlook' to see if other people are reporting the same problem right now. If there is an outage, you need to wait. It usually resolves within a few hours.
    6

    Update or reinstall the email app

    ~18s
    An outdated app can stop working after the email service updates its systems. On an iPhone, open the App Store and tap your profile icon to see available updates. On Android, open the Google Play Store and do the same. Install any updates for your email app and try again.

    Email problems tend to fall into a few categories: your internet connection is down, your account password has changed, the email service itself has a temporary outage, or your storage is full. Each has a clear fix.

    The most common scenario is that nothing is actually wrong with email itself — the internet connection is the real problem. Before doing anything else, try opening a website in your browser. If it doesn't load, fix your internet connection first (restart your router) and then check email again.

    Another very common cause: your email account got signed out automatically. This happens after password changes, security updates, and app updates. Sign back in.

    This guide works for the major free email services — Gmail (Google), Yahoo Mail, and Outlook (Microsoft) — whether you are using them in a web browser or in a phone's mail app.
