Validate Emails

Data Validation20 credits/cellSheets · Excel
=VERVE("emailvalidator", "[email protected]", "field", "domain")

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.

Clean a list before you send

Add a validity column to a mailing or signup list and filter out the addresses that would bounce before they cost you deliverability.

Keep company leads only

Flag free-provider and disposable addresses beside a lead sheet so sales sees the business emails first.

Catch typos at the source

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.

Google SheetsAdd-on

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")
Microsoft ExcelAdd-in

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.

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. Everything unmarked works on every plan. Compare plans

Validate Emails, answered

Everything you need to wire it into a sheet.

How do I validate a list of emails in Google Sheets?
With the address in A2, type =VERVE("emailvalidator", A2, "field", "isValid") in B2 and drag it down. Each row reads TRUE or FALSE, so you can filter the list down to the good ones. In Excel it's =VERVE.CALL("emailvalidator", A2, "field", "isValid").
What does "valid" actually check?
That the address is well-formed and that its domain has a mail server set up to receive email (MX records). It doesn't send a message or log into the mailbox, so it can't promise a specific inbox exists — it catches the typos, dead domains and junk that make up most bad addresses.
How do I find disposable or role-based emails?
Use the "isDisposable" field for throwaway services and "isRoleAccount" for addresses like info@, sales@ or support@. "isFreeEmail" flags Gmail, Yahoo and similar — useful when you only want company addresses.
How much does it cost to validate a list?
Each address costs 20 credits, so a 1,000-row list is 20,000 credits. Validate once and paste the results as values if the list won't change — that way a refresh doesn't re-check it.
How do I pull Validate Emails into Google Sheets?
Install the VerveSheets add-on, sign in once with your key, and type =VERVE("emailvalidator", "[email protected]", "field", "username") into any cell. The "field" argument names the value you want back, so the cell resolves to a single number or string you can chart, sort, or feed into another formula.
What data can I pull from Validate Emails?
Validate Emails returns username, domain, isValid, isRegexValid and isMxValid, plus 5 more — name any one of them as the "field" argument and that value lands in the cell. Leave the field out and the whole record spills into a two-column table instead.
Which Validate Emails fields need a paid plan?
suggestedCorrection and riskScore are included from the Starter plan up. On the Free plan the cell returns #PREMIUM(field) rather than a wrong or empty value, so it's always obvious which one to upgrade for. Every other field works on Free.
Can I fill a whole column of Validate Emails at once?
Yes. Put your email values down a column and point the formula at the range — A2:A50 instead of A2 — and one call returns a value for every row. Dragging the formula down works too, but the range form is a single billed call per column rather than one per cell.
How many credits does each Validate Emails cell cost?
Each resolved cell costs 20 credits. A cell only re-bills when it actually refreshes, so a sheet you aren't touching doesn't keep charging.
Does Validate Emails work in Excel as well as Google Sheets?
Yes — same arguments, same key, same fields. Excel namespaces custom functions, so the call is =VERVE.CALL() there and =VERVE() in Google Sheets; nothing else about it changes.

Put Validate Emails in your next spreadsheet. Add the extension, paste the formula, and the cell keeps itself current.
