Claude and ChatGPT

Clay
Early accessEnrich a list in Clay, write the personal first line there, and send each row to a mailing with an HTTP call.
Instantly
Early accessWhen a lead replies, or goes quiet after a sequence, a webhook triggers a handwritten follow-up.
Your CRM
Early accessGoHighLevel, HubSpot, or anything that talks to Zapier or n8n. A new client, a closed deal or a stage change can trigger a piece.
REST API
Early accessCreate jobs, add recipients, preview every piece as an image and approve the sample. Comes with an OpenAPI spec.
How it works
Three steps. A spreadsheet is the only prep.
Send a CSV
Name, address, and a short message field for each recipient. That is the whole spec.
We write each one
Every envelope is addressed by a machine holding a real pen.
We stamp it and mail it
Your printed insert goes inside, a real First-Class stamp goes on, and we mail it. Postage is included.
CSV works today. The API and AI connections are in early access.
