Yes — OpenClaw 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 OpenClaw’s chat, on your own machine or server. 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.
OpenClaw is a self-hosted agent: it runs on a machine you control, and you talk to it from its own chat rather than a vendor’s window. It connects with two commands — one registers the server with sign-in enabled, the second opens a WarmySender sign-in in your browser. OpenClaw ignores static headers while sign-in is on, so no key is ever stored. Verification via OpenClaw suits lists that stay on your own machine until the moment they are submitted: OpenClaw submits the batch, follows it, and turns the safe addresses into a prospect list. Allowance and pacing are exactly the app’s.
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. |
OpenClaw registers WarmySender from its command line and signs in through your browser — after that it can call every tool from its chat.
Run both lines; the second opens a WarmySender sign-in in your browser. OpenClaw ignores static headers while sign-in is on, so no key is ever stored.

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.
Submit this list for verification, follow the batch until it finishes, and make a prospect list from the safe results.
OpenClaw 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 OpenClaw to WarmySender and ask in plain language, in OpenClaw’s chat, on your own machine or server — 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.
OpenClaw registers WarmySender from its command line and signs in through your browser — after that it can call every tool from its chat. Run both lines; the second opens a WarmySender sign-in in your browser. OpenClaw ignores static headers while sign-in is on, so no key is ever stored. The command text is: openclaw mcp add warmysender --url https://warmysender.com/mcp --transport streamable-http --auth oauth openclaw mcp login warmysender — the server address is https://warmysender.com/mcp. The steps are on this page under "Connect OpenClaw", 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. OpenClaw 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 OpenClaw 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.
OpenClaw keeps the sign-in it obtains from the browser flow that the login command opens. No API key is written to its configuration, because OpenClaw ignores static headers while sign-in is on.
Yes, as long as the one-time sign-in can be completed in a browser. WarmySender is a hosted server at https://warmysender.com/mcp, reachable from any machine, and the mailbox stays connected in WarmySender — never on the agent host.
Yes — create a key under Settings › API Keys and use the key form on the AI Agents hub, which registers the server without the sign-in flag. With sign-in on, OpenClaw ignores static headers, so pick one route or the other.
