Yes — Claude can verify email addresses and turn the clean ones into a campaign in WarmySender, all in plain language, through the same 78-tool connection Claude, ChatGPT, Cursor, Codex, OpenClaw, and Hermes Agent share. You ask in Claude’s chat, on the web or in the desktop app. It never sends a message itself and can never raise a limit: it writes the campaign and hands it to WarmySender’s scheduler, which paces every email, LinkedIn, Instagram and WhatsApp action inside safe limits no matter who is driving. Connecting and disconnecting accounts stays in the app.
You talk to Claude in an ordinary chat window — on the web or in the desktop app — so there is nothing to install on your machine and it works from any computer you sign in to. It connects as a custom connector: open Customize → Connectors, add a custom connector, paste the server address and approve the WarmySender sign-in that opens. Verification is the kind of task you hand over and come back to: describe or paste the list in Claude’s chat, ask it to verify and tell you when it is done, then have it build the clean list into a campaign in the same conversation.
Every "can" below stands on a real tool in the WarmySender connection. Every "cannot" is not a setting — there is simply nothing an agent can call that does it.
| Can / cannot | What that means for email verification |
|---|---|
| Can | Check a single address on the spot — safe to send to, risky, or not deliverable. |
| Can | Submit a whole list and follow the results as they come in. |
| Can | Check how much of your allowance is left before committing a big list. |
| Can | Stop a batch that is still running. |
| Can | Turn the confirmed addresses into a prospect list, ready to enroll. |
| Can | Build and start the campaign around the clean list in the same conversation. |
| Cannot | Send to anyone — building the campaign only hands it to WarmySender’s scheduler. |
| Cannot | Verify faster than the app or raise your allowance — it shares the same monthly allowance and pacing. |
| Cannot | Buy credits — anything touching billing stays with you in the app. |
| Cannot | Find an address you do not have — verification confirms addresses, it does not discover them. |
| Cannot | Connect or disconnect a mailbox. |
Claude on the web and in the desktop app connects to WarmySender as a custom connector — paste one address, sign in, and every tool is available in the chat.
In Claude open Customize → Connectors, choose + then Add custom connector, paste this address and click Add. Claude then opens a WarmySender sign-in — approve it and you are connected.

Prefer a key? Create one under Settings › API Keys and choose exactly which permissions it carries, including read-only. With a key, the Claude route is: Paste into your claude_desktop_config.json and restart Claude Desktop.
Both routes reach the same workspace and stay inside the same safe limits. Every agent's steps live on the AI Agents hub.
How much verification allowance do I have left this month?
Verify this list of 800 addresses and tell me when it is done.
Make a list of the addresses that came back safe to send, then build a campaign around them.
Stop the batch I started an hour ago.
Verify the addresses I pasted, tell me how many came back safe, and build a campaign around only those.
Claude never sends a message itself and can never raise a limit. Creating or launching a campaign only writes it and hands it to WarmySender's scheduler, which paces every email, LinkedIn, Instagram and WhatsApp action inside safe limits and a gradual ramp — the same protections that apply when a human clicks the buttons. Connecting and disconnecting accounts stays in the app. Account safety always wins.
Yes. Connect Claude to WarmySender and ask in plain language, in Claude’s chat, on the web or in the desktop app — it can verify email addresses and turn the clean ones into a campaign. It never sends a message itself and can never raise a limit: it writes the campaign and hands it to WarmySender’s scheduler, which paces every email, LinkedIn, Instagram and WhatsApp action inside safe limits no matter who is driving. Connecting and disconnecting accounts stays in the app.
Claude on the web and in the desktop app connects to WarmySender as a custom connector — paste one address, sign in, and every tool is available in the chat. In Claude open Customize → Connectors, choose + then Add custom connector, paste this address and click Add. Claude then opens a WarmySender sign-in — approve it and you are connected. The address to paste is https://warmysender.com/mcp. The steps are on this page under "Connect Claude", and the full install hub for every agent is at /ai-agents.
No. Nothing an agent can call moves a limit — not your monthly verification allowance or the pace at which a batch is checked. Claude can read where you are against a limit and tell you when a pause lifts; WarmySender’s scheduler decides what actually goes out.
No. Connecting and disconnecting accounts stays in the app on purpose — a credential should never pass through an agent or a chat log. Connect the mailbox once in WarmySender; after that Claude can use it.
Exactly as in the app: the agent shares the same monthly allowance and credits and cannot verify any faster. You are only charged for answers — one credit per confirmed result, nothing for one that cannot be confirmed either way — and credits never expire.
Both work. Add WarmySender once as a custom connector under Customize → Connectors — paste the address https://warmysender.com/mcp, click Add and approve the sign-in — and ask in whichever Claude chat you use.
Yes. Claude Code registers the same server with one terminal command and signs in the same way; its steps are on the AI Agents hub. This page covers Claude in the web and desktop apps, where no terminal is involved.
No. Adding the connector opens a WarmySender sign-in in your browser; you approve it there, and Claude holds only permission to call the tools — which you can remove at any time from Claude’s connector settings.
