Connect Claude & ChatGPT to Bulk Email Checker
Ask your AI whether an email address is safe to send to before you add it to a list or reply to a lead. It checks the address in real time with Bulk Email Checker and tells you if it is deliverable, if the domain is disposable, and if the address looks like a typo of a common one.
Free plan, no credit card. Takes about a minute.
Try asking
“Is [email protected] a real, deliverable address?”
The AI checks the address in real time and reports whether it passed, failed or came back unknown.
“This signup used [email protected]. Is that a typo?”
It verifies the address and points out a likely typo if Bulk Email Checker suggests a correction.
“Check if the address on this new lead is a throwaway inbox.”
It verifies the address and tells you whether the domain is a disposable email provider.
What your AI can do
Real-time checks
Verify one email address at a time and get a pass, fail or unknown result straight away.
Disposable and typo detection
See whether an address uses a disposable domain and whether it looks like a typo of a common address.
Labels for failed addresses
Add a label to a check so failed addresses are tagged in your Bulk Email Checker account.
“Verify these five addresses before I send the invite.”
It checks each address one by one and gives you a short list of which ones passed and which failed.
“Verify [email protected] and label it 'webinar-import' if it fails.”
It runs the check with your label, so a failed address is tagged in Bulk Email Checker.
“Why did this address fail?”
It reads the check result back to you, including the reason Bulk Email Checker gives for the failure.

Questions
What can the AI do in Bulk Email Checker?
The AI can verify a single email address in real time. It gets back whether the address is deliverable, whether the domain is disposable and whether it looks like a typo. You can also pass a label to tag failed addresses.
Does the AI see my Bulk Email Checker API key?
No. Your Bulk Email Checker API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.
Can I control what the AI is allowed to do?
Yes. You choose which tools are switched on, and the verification tool can require your approval before it runs if you want to watch your credits. Every tool call is logged.
Does it work with ChatGPT?
Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.
What does it cost?
PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Bulk Email Checker account.
Does each check use a credit?
Yes, a passed or failed check uses one Bulk Email Checker credit. Checks that come back unknown are free. The AI checks one address per call, so a list of ten addresses uses up to ten credits.
