Gmail Username Checker — Bulk Availability Lookup

What does Gmail Username Checker do?

Gmail Username Checker tells you whether Gmail addresses are still free to register, in bulk, without creating any account. Give it a list of usernames or full addresses (joe or joe@gmail.com both work) and you get one row each with available: true or false.

It runs on Apify, so you can call it from the API, schedule it, or send the results to Google Sheets, Make, Zapier or n8n.

What people use it for

• Brand protection: check whether your brand or product names are still free on Gmail before someone else takes them.
• Picking a username: test a list of ideas at once instead of trying them one by one in the sign-up form.
• Account and lead hygiene: see which addresses in a list exist as Gmail accounts at all (a taken name is a registered account).
• Name research: check one handle across services, together with the other username checkers below.

How to use it

1. Click Try for free.
2. Paste your usernames or Gmail addresses into emails or/and usernames, one per line.
3. Click Start. Results appear in the Output tab as they're checked.
4. Download as JSON, CSV or Excel, or use the API.

Input

{
  "emails": ["mybrand2026", "jane@gmail.com", "joe"]
}

Field	Type	Description	Default
emails	array	Usernames or Gmail addresses to check, up to 1,000 per run. You can also pass one comma- or newline-separated string	required

Output

One row per checked name:

{
  "email": "mybrand2026",
  "available": true,
  "quota": "Paid plan: unlimited usage."
}

Field	Type	Description
email	string	The username or address you gave
available	boolean	true if it can still be registered, false if it's taken
quota	string	Your plan's usage note (see below)

If Gmail doesn't answer for a name after several tries, that name isn't saved or charged. It's listed in the run's status message so you can run it again.

Free plan limit

On Apify's free plan you can check 20 names every 30 days. Paid Apify plans have no limit. When the free limit is used up, the run ends with a message saying so, and nothing is charged.

How many results will I get?

One row per name, up to 1,000 per run. You pay per result; your plan's rates are on the Pricing tab.

FAQ

Does it create accounts or send anything to the person? No. It asks Gmail's sign-up form whether a name is free, like typing it in yourself, and stops there.

Can I check other email providers? No, Gmail only. The related tools below cover other sites.

Is it maintained? Yes, I keep it running. If something breaks, open an issue in the Issues tab and I'll look at it.
