About the Email Typo Checker

Mistyped domains are a large share of the invalid addresses on any list built from a signup form, and unlike most bad addresses they are worth saving rather than deleting: the person meant to give you a real one and missed by a letter.

This finds them three ways. Named misspellings are matched outright, so gmial.com, gmai.com, hotnail.com and yahooo.com are caught with certainty. Top-level domain slips are checked separately, which is how anything ending .con, .cmo or .ner gets picked up whatever the domain is. Anything else is measured by edit distance against the common providers, with the threshold scaled to the length so short real domains are left alone.

Each hit comes with the corrected address in full, ready to copy back into your list or into a "did you mean" prompt on your own signup form.

Key features of the Email Typo Checker

Three detection passes

Certain matches first, edit distance only as a fallback.

TLD slips caught

Anything ending .con, .cmo or .ner, whatever the domain is.

Guards against false hits

Known providers are never "corrected", and short domains need an exact-ish match.

Full corrected address

Not just the domain — the whole address, ready to use.

Bulk capable

Run a whole list and copy only the rows that changed.

How to use the Email Typo Checker

  1. 1

    Paste your addresses

    One or a whole list — every line is checked.

  2. 2

    Read the suggestions

    Each likely typo is shown with the domain it was meant to be.

  3. 3

    Check the confidence

    A named misspelling is certain; an edit-distance match is a guess.

  4. 4

    Copy the corrected list

    Take the fixed addresses, or just the ones that changed.

Frequently asked questions

Two ways. Common misspellings are held in a list and matched exactly, which is certain. Anything else is measured by Levenshtein edit distance against the popular providers, with the threshold scaled to the domain length so a short real domain is not "corrected" into something else.
