Claude connector

Email verification without leaving Claude

Connect mailfloss to Claude to check an email address or a list in the conversation you’re already having. Ask for the result and the reason behind it, or see which email platforms you have connected to mailfloss.

You’ll need a Claude account and a mailfloss account. Verification uses mailfloss credits.

Ask for the answer you need

Check an address before your next step
Ask Claude to verify an email address with mailfloss and explain the result. Read the status and reason together before deciding what to do with that address.
“Verify [email address] with mailfloss and explain the result.”
Work through a list
Ask Claude to start a batch verification, check its progress, and retrieve the results. Use the results to decide which addresses need attention before your next send.
“Verify these email addresses as a batch with mailfloss, then show me the results when the job finishes.”
Check your account in the same conversation
Ask about your remaining credits, usage or existing email-platform connections when you need that context.
“Show my remaining mailfloss credits.” “List the email platforms connected to my mailfloss account.”

These are illustrative requests, not recorded conversations or sample results. Verification does not send an email campaign.

Connect, sign in, then try a question

The directory sign-in flow does not require you to create or paste an API key. For the full setup steps and tool reference, see the mailfloss MCP guide.

01
Open the listing
Open the mailfloss listing in Claude’s connector directory.
02
Connect and sign in
Connect it and sign in to your mailfloss account. Review and approve the requested access.
03
Try a question
Enable mailfloss in your Claude conversation, then start with a question such as “Show my remaining mailfloss credits.”

Choose the right place for the task

Use the Claude connector for a conversational way to verify addresses and lists or inspect your mailfloss account. Connect new email platforms in the mailfloss dashboard; the connector’s tools work with existing connections.

If you’re building email verification into your own product or workflow, start with the mailfloss email verification API. The connector uses that API through MCP; the API remains the developer path for a custom implementation.

Know what each request does

Verification uses your mailfloss credits. Some connector tools can also change settings or disconnect an email-platform connection. Review Claude’s tool permissions before enabling automatic approval; a confirmation prompt depends on those settings.

Asking for verification results is a separate step from deciding how to handle the addresses. Don’t treat a result you haven’t reviewed as an instruction to send a campaign or change your connected platform.
