WHY THE MCP SERVER?

Verification becomes part of the conversation

No new tool to learn

Verification stops being a separate process with another login, upload and export.

Hand over the whole CSV

The assistant finds the addresses, sends one batch and returns clean results.

The full Bouncer, not a demo

Real-time, bulk, domain and toxicity checks with the same capabilities as the API.

EMAIL LIST WORKFLOW

Your email list goes straight into the chat

Simply paste a list of email addresses or the CSV export from your CRM, newsletter tool or event platform. The assistant finds the addresses, creates one batch in Bouncer, watches it finish and brings back the results.

Then keep talking: ask for only undeliverables, an explanation of a bounce, or a cleaned file ready to import.

See what the results mean

SAME ENGINE, SAME OUTPUT

The same results you already know

No new output format to learn. Every address comes back with one of four statuses, identical to the Bouncer app and API.

deliverable

The mailbox exists and accepts mail. This address is safe to send to.

Keep in your sending list

risky

Sending is possible, but you should focus on what to do (based on your business case).

Review before sending

undeliverable

The address does not exist or its domain will not accept mail. Sending to it will result in a bounce.

Remove from your list

unknown

The receiving server did not answer in time, so Bouncer could not determine the result. No credit is charged.

Retry verification later

quality flags

Your assistant can also explain disposable, role-based, free provider, catch-all and full mailbox signals, along with a toxicity score.

REAL PROMPTS

What people ask it for

Nothing to configure. Type what you want and Bouncer selects the right verification action.

01 Email Marketing

“Here’s our newsletter CSV. Verify it and tell me which contacts to drop before Friday’s campaign, and why.”

02 Sales & prospecting

“Check whether margareth.doe@acme.com exists before I send her the offer.”

03 CRM Hygiene

“Which of these are temporary or role-based? Give me a CSV I can use to clean the database.”

04 Deliverability

“Run this list through the toxicity check. I want to know about breached addresses and spam traps before we send.”

05 Operations

“How many credits do we have left? Is that enough to verify 300,000 addresses?”
