About Email Validator

Email Validator closes a gap most marketing stacks leave open. Verify syntax, domain, MX records and deliverability for an email list. The result is a sortable table you can use immediately.

Because it runs in bulk, you can check an entire site, client portfolio or prospect list in one pass instead of repeating the same lookup by hand. Results come back as a sortable table you can export.

Email Validator is free to use with no account required. Signing in adds saved history, favourites and higher daily limits, and unlocks the other 311 tools on the platform.

How to use Email Validator

1
Enter your list

Paste your list with one entry per line — up to 500 per run.
2
Set your options

Adjust the settings to match your use case. Defaults are chosen to be sensible for most people, so you can usually skip this step.
3
Run the tool

Press Run. Progress is shown while it works, and most runs finish in under two seconds.
4
Review the result

Sort any column by clicking its header to find the rows that matter most.
5
Export or share

Copy to clipboard, download the raw output, export to PDF, CSV or JSON, or share a link to this tool with your team.

Why teams use it

Stop paying for a single-purpose tool

Email Validator is one of 312 tools on the same account. One subscription replaces the handful of point solutions most marketing teams end up stacking.

Get to the decision faster

The output is structured around what you will do next, not around what was easiest to measure. Less interpretation, fewer meetings.

Share results without a screenshot

Export to PDF or CSV, or send a link. Clients and colleagues see the same thing you do, formatted properly.

Works the same on every device

The full workspace — including tables and exports — works on a phone, a tablet and a 4K display without a separate app.

FAQ

Email Validator — frequently asked questions

Yes. Email Validator is free with no account required, subject to a fair-use daily limit. Creating a free account raises that limit and saves your history; paid plans remove it entirely.

Results come from live sources at the moment you run the tool. Where a value is an estimate rather than a measurement — search volume and traffic estimates in particular — it is labelled as such so you can weight it accordingly.

No. Everything runs in the browser. There is nothing to download, no extension to approve and no desktop client to keep updated.

Up to 500 entries per run on paid plans, and 50 on the free tier. For larger lists, split them into batches or use the API on Business and Enterprise.

Yes — copy to clipboard, download the raw output, or export to PDF, CSV or JSON. Business and Enterprise plans can also white-label exports with your own logo and colours.
