Frequently Asked Questions
- How many emails can I check at once?
- Thousands. Paste one email per line and the tool validates them all in the browser with no upload or rate limit.
- How do typo suggestions work?
- The tool measures Levenshtein distance between the input domain and a list of popular domains (gmail.com, yahoo.com, hotmail.com, outlook.com, icloud.com, protonmail.com, aol.com). A distance of 1–2 triggers a suggestion.
- Does it verify the mailbox exists?
- No. The tool only checks syntax and suggests domain corrections. SMTP verification is not performed because all processing is client-side.
