Integrations
ChatGPT integration
Ask ChatGPT whether an address can receive mail, or have it sort a short list, through our MCP server. ChatGPT connects to it as an app in developer mode and you sign in on our site, so there is no key to paste.

- ChatGPT users on the web who check addresses as they work: before adding a contact, answering a lead or cleaning a short list.
- You need
- A ChatGPT plan with developer mode (Plus, Pro, Business, Enterprise or Edu, on the web) and an account on our site. In a Business, Enterprise or Edu workspace, an admin has to allow developer mode first.
- Costs
- 1 credit = 1 validated address, as with any API request. Free: unknown results, API errors, malformed addresses and test addresses on sandbox.email-validation.org.

Typical uses.
Check one address
Paste an address into the chat and ask if you can send to it. ChatGPT answers with its status, reason and the recommended action.
Check a list
Paste a few addresses and it checks each one. For a longer list it can start a bulk job and report the counts by status, with a sign-in that allows Bulk; the results file is in your dashboard.
Read your balance
Ask how many credits you have left and when the next ones expire. Reading the balance is free.

Click Create app, enter a name and
https://api.email-validation.org/mcpas the server URL, and choose OAuth as the authentication.Sign in and allow it
ChatGPT sends you to our site: sign in, check the permissions it asks for and allow it.

Open the + menu of the message box, choose Developer mode and turn the app on. Then ask it to validate
accepted@sandbox.email-validation.org.
Good to know.
- ChatGPT asks you to confirm each check and each bulk job before it runs, because they spend credits.
- A signed-in app has no daily credit cap: it can spend up to your whole balance. Disconnect it at any time under API keys, in Connected apps.
- ChatGPT cannot send a fixed API key to an MCP server, so it always uses the sign-in.
- Try it first with
accepted@sandbox.email-validation.organd the other test addresses: each returns the result its name says and costs nothing.
