Email Auto-Domain
Type your email prefix and "@" — the domain fills in instantly. Catches typos, suggests saved domains, and works on any site.
Add to Chrome — it's free
What it does
Email Auto-Domain speeds up filling in email fields anywhere on the web. Type a prefix you've used before, followed by "@", and it instantly completes the domain — or shows a quick dropdown of your saved domains if there's more than one match, selectable with Alt+1 through Alt+6.
It also catches common typos in popular providers like Gmail, Outlook, and Yahoo before you submit a form, and lets you set up different saved addresses for different websites — handy if you use separate emails for work, personal accounts, or sign-ups.
