Yes — ChatGPT can build, launch and manage your cold email campaigns in WarmySender, all in plain language, through the same 78-tool connection Claude, ChatGPT, Cursor, Codex, OpenClaw, and Hermes Agent share. You ask in Codex, signed in with your ChatGPT plan, in your terminal. 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.
ChatGPT reaches WarmySender through Codex, which is included with ChatGPT Plus and every plan above it — so you talk to it in the Codex terminal rather than the ChatGPT website. It connects with two terminal lines: one registers the server, the second opens a WarmySender sign-in in your browser. This path suits people who already keep a terminal open and want cold email wired into the rest of their work: pull a list out of a file, ask Codex to create the campaign from it, then start it. Setup takes a minute and there is no key to paste.
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 cold email |
|---|---|
| Can | Create a multi-step campaign, edit it, and set the sending window and daily limits. |
| Can | Start, pause and resume a campaign — starting only hands it to the scheduler. |
| Can | Add prospects one at a time or in bulk, update their details, and enroll or unenroll them. |
| Can | Work from your saved email templates instead of writing every email from scratch. |
| Can | Read and add to your suppression list so the wrong people are never contacted. |
| Can | Report on every campaign and explain why nothing went out today. |
| Can | Add a branded tracking domain and check that it is set up correctly. |
| Can | Set the postal address and opt-out wording used in your email footer. |
| Cannot | Send an email itself — it writes the campaign and WarmySender’s scheduler sends at your safe pace. |
| Cannot | Raise a daily cap, a warmup stage or a domain ceiling — nothing it can call moves a limit. |
| Cannot | Connect or disconnect a mailbox — credentials never pass through an agent. |
| Cannot | Switch off the opt-out in your footer — it can change the style, never remove it. |
| Cannot | Read or reply to responses — replies stay in WarmySender’s inbox, with you. |

Create a three-step campaign called "Agency founders" for this list, weekdays only, from my two warmed mailboxes, then start it.
Pause every campaign that uses the sales@ mailbox until Monday.
Why did the "Q4 partners" campaign send nothing yesterday?
Add these 40 people to the suppression list and take them out of any running campaign.
Read prospects.csv in this folder, create a two-step campaign from it called "Q4 partners" on my warmed mailboxes, and start it.
ChatGPT 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.

No. Nothing an agent can call moves a limit — not a mailbox’s daily cap, your domain’s ceiling or the pace across the sending window. ChatGPT 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 ChatGPT can use it.
Nothing goes out in a burst. Starting a campaign only queues it, and WarmySender’s scheduler drains that queue at your normal daily pace across your sending window, inside each mailbox’s limit and your domain’s ceiling. Pausing is one sentence and is never blocked, and everything the agent built is a normal campaign you can open, edit or delete.
