Checks each email address in a column and tells you whether it's usable: is the syntax valid, does the domain have a working mail server, is it a throwaway (disposable) address, a free provider like Gmail, or a role account like info@. Run it before you import a list, send a campaign or hand leads to sales.
It's one of 250+ live sources you reach with a single =VERVE() function — served from APIVerve's production data engine, billed at 20 credits per resolved cell, and refreshed on whatever cadence you set. No API keys to wrangle, no scripts, no exports.
A real example — the input you type, and the values you can pull from it. Click any cell to see the formula behind it.
Add a validity column to a mailing or signup list and filter out the addresses that would bounce before they cost you deliverability.
Flag free-provider and disposable addresses beside a lead sheet so sales sees the business emails first.
Run new form submissions through "hasTypo" and follow up on gmial.com-style mistakes while the contact is still warm.
The same function works in both apps — install once, sign in with your key, and type it into any cell.
Install from the Workspace Marketplace, then drop the formula into a cell. Autocomplete suggests the source and its fields.
=VERVE("emailvalidator", "[email protected]", "field", "domain")Same source, same arguments, same key — in Excel on desktop, the web, or mobile. Excel namespaces it as VERVE.CALL. Drag to fill a whole column.
=VERVE.CALL("emailvalidator", "[email protected]", "field", "domain")Add a field name as the last argument to land just that value in the cell.

On the Free plan a marked field is withheld and a marked input is ignored — either way the cell reads #PREMIUM(name) instead of a value, so a gated answer can never be mistaken for a real one.
