Is the email redactor free?
Yes. This email redactor is free to use, with no account or sign-up.
Is my text uploaded to a server?
No. The redactor runs entirely in your browser, so your text and email lists stay on your device and are never uploaded.
Can I keep the email domain visible?
Yes. The mask-local mode keeps the domain visible and masks only the local part of each address.
Does it work on plain text and lists?
Yes. You can paste normal text or an email list, and the tool redacts the addresses it finds in either case.
Is this meant for bulk uploaded files?
No. This tool is paste-first text cleanup and does not process uploaded files in bulk.
Is the text uploaded to redact it?
No. The substitution happens in the page with a regular expression, so the text never leaves your browser. This matters more here than in most tools, because the input is by definition a list of real people's addresses.
Should I use the placeholder or the mask?
Use the placeholder when the address has no further use, for example in a bug report or a public paste. Use the mask when a colleague still needs to know which company or which mailbox domain the message came from. The mask keeps the domain intact, so treat it as partial redaction rather than removal.
What does the mask actually keep?
The first character of the local part, the last character of the local part, and the full domain. Everything between the first and last character becomes stars, with at least two stars used so that a two-letter mailbox does not reveal its own length. So support@acme.com becomes s*****t@acme.com.
Why was an address in my text not redacted?
The pattern needs a normal-looking address: some characters, an at-sign, a domain with a dot, and a top-level domain of two or more letters. Anything written to defeat scrapers, such as jane (at) acme (dot) com, does not match that shape and survives. So do addresses split across a line break.
Can I paste a whole CSV or an email list?
Yes. The tool treats the input as one block of text and replaces every match it finds, so a column of addresses pasted from a spreadsheet is redacted line by line and the rows stay aligned. The other columns are left exactly as they were.
Does redacting the address make my data anonymous?
Rarely. An email address is one identifier, and the surrounding text usually carries others: a name in a signature, an account ID, a phone number, or a domain that names the company. Use this when the address is the specific thing you need gone, and use the text anonymizer when you want the other common identifiers removed too.
