Email typo checker
Paste your email addresses, one per line. We find the typos that bounce campaigns: gmial.com, outlok.com, .con, double or missing @, commas instead of dots. It runs in your browser, so your list never leaves your computer.
DecodingPro cleans emails, phone numbers, dates and duplicates across an entire Excel or CSV file, re-checks every change against your original and flags anything unclear instead of guessing. You start with 100 free credits.
Clean a whole spreadsheetWhat this checker does and does not do
It fixes mistakes that are almost certainly typos: a known provider spelled wrong (gmial.com becomes gmail.com), a wrong ending (.con, .cmo), a comma where a dot belongs, spaces inside an address, a doubled @, or a missing @ before a well-known provider.
It does not check that a mailbox exists, and it never invents an address. Anything it cannot fix with confidence is marked Check for you to look at. For a bigger problem, see our guides on cleaning messy Excel data, removing duplicates and data entry accuracy.
