Flag throwaway emails by the row. Checks a column against 100K+ disposable domains — Sheets or Excel.
It's one of 250+ live sources you reach with a single =VERVE() function — served from APIVerve's production data engine, billed at 6 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.
Run =VERVE("emaildisposablechecker", "field", "isDisposable") down a column of inputs and let each row tell you whether it's real and safe — catch the bad ones before they hit your workflow.
Add a validity column beside your contacts so you can filter, sort, or conditionally format the rows worth keeping.
Wrap =VERVE("emaildisposablechecker", "field", "isDisposable") in an IF and flag anything that fails, turning a raw import into a checked, trustworthy sheet.
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("emaildisposablechecker", "field", "isDisposable")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("emaildisposablechecker", "field", "isDisposable")Tune the result by adding name=value before the field argument — in any order. Leave one out and its default applies.
The email address to check (e.g., support@myspace.com). Send this or domain
=VERVE("emaildisposablechecker", "email", "support@myspace.com")A domain to check instead of a full address (e.g., mailinator.com). Send this or email
=VERVE("emaildisposablechecker", "domain", "mailinator.com")Add a field name as the last argument to land just that value in the cell.
=VERVE("emaildisposablechecker", "field", "isDisposable")=VERVE("emaildisposablechecker", "field", "isRelay")=VERVE("emaildisposablechecker", "field", "relayService")=VERVE("emaildisposablechecker", "field", "isDisposableMx")=VERVE("emaildisposablechecker", "field", "email")=VERVE("emaildisposablechecker", "field", "domain")Premium marks data included on paid plans. 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.
