Ask before you fix an email typo

Someone types [email protected]. Your form suggests gmail.com. Good.

Your form silently changes it and sends an account link there. That's a different decision, and you don't know enough to make it.

A near-match might be a typo, an unfamiliar business domain or an address belonging to somebody else. Even a domain that looks misspelled may receive mail. Don't assume it is dead.

Show a suggestion the person can accept or ignore:

Did you mean [email protected]?

Use suggestion · Keep my address

Keep the original text until they choose. Never replace an unfamiliar company domain just because it resembles a popular provider.

Basic format checks can catch missing pieces and obvious mistakes. A verification check can find additional problems, but it won't reliably catch a typo that happens to form another working address.

After submission, show the address you used and provide an edit option. “We sent a confirmation to sara@…” is more useful than “Check your inbox” when someone is wondering why nothing arrived.

For an account that depends on email ownership, complete confirmation before granting the access tied to that address. Keep verification and confirmation as separate steps.

The person filling in the form is the best source for the address they intended. Give them a chance to correct it while they're still there.
