Route 01The model

Your email sending service sends the emails.GoodPostal handles the rest.

GoodPostal works with the email service you already use: Amazon SES, SendGrid, Mailgun, Postmark, SMTP2GO, or Mailtrap.

Your emails still send from your own account, so you keep your service’s wholesale rates.

GoodPostal handles everything else: the email editor, the AI, the contacts, the analytics, the tracking.

All of it is $19 a month flat, plus 5 cents per 1,000 emails sent.

Route 02Create

ChatGPT, Claude, Claude Code, Codex, Cursor, Gemini, Gemini CLI, and anywhere MCP is available.

Build with the AI tools you already love.

Draft your next campaign in ChatGPT, Claude, or straight from the command line. GoodPostal plugs into the AI tools you already work in, then hands you a drag and drop editor for the final polish. The result is an email you’d be proud to send.

Route 04Built in

Everything a serious sender needs.

Connect your own service

Your keys, your account, your sending reputation. We never resell delivery or mark it up: you pay Amazon SES, SendGrid, Mailgun, Postmark, SMTP2GO, or Mailtrap directly, at their rates.

All six services, or any SMTP server

AI in every client

Start a campaign from ChatGPT, Claude, Cursor, or your terminal, or any tool over the REST API. Scoped keys, masked contact details, and approval gates mean an AI employee can run your email safely.

Your next campaign starts with a sentence

We protect your reputation

Preflight checks on domains, webhooks, and suppression lists keep your email sending service from suspending you. Your contacts stay encrypted and isolated, and unsubscribes are honored automatically.

Checks run before every campaign sends

Scheduling

Queue a campaign for any date and time. Large sends are paced automatically to your service's send rate.

Teams

Separate workspaces for every brand or client, each with its own senders, contacts, and analytics. Owner, Admin, and Member roles.

API access

Every dashboard action is also an endpoint, with scoped keys per integration.

MCP server

Connect Claude, ChatGPT, Cursor, or any assistant that speaks the Model Context Protocol. AI drafts, humans confirm.

Route 05The per-contact tax

Stop paying for contacts you don’t email.

Most email marketing platforms charge you for every contact on your list, whether you email them or not. GoodPostal is $19 a month plus 5 cents per 1,000 emails sent, and delivery runs through your own email service at their wholesale rates.

Compare it yourself below. Select the platform you’re on now and your contact list size, then see the pricing side by side: them vs us.
