GoodPostal

GoodPostal is an email campaign platform that does not send the email itself. The customer connects a sending service it already pays for (Amazon SES, SendGrid, Mailgun, Postmark, SMTP2GO, Mailtrap or any SMTP server) and GoodPostal supplies what those services leave out: the editor, the AI drafting, the contacts, the scheduling, the tracking and the analytics. Its homepage puts the pricing in one line: "$19/mo for GoodPostal, then 5¢ per 1,000 emails sent", with "No contact pricing. No list-size tax." It is aimed at newsletter senders, small teams and agencies who want a campaign tool without paying for every contact on their list.

How the model works

The homepage splits the job in two: "Your email sending service sends the emails. GoodPostal handles the rest." Mail goes out through the customer's own account, so it keeps that service's wholesale rates and its own sending reputation. GoodPostal says it never resells or marks up delivery: the customer pays Amazon SES, SendGrid, Mailgun, Postmark, SMTP2GO or Mailtrap directly, at their rates, and pays GoodPostal only for the software and the metered sends.

The argument behind this is stated plainly on the homepage: "Most email marketing platforms charge you for every contact on your list, whether you email them or not." GoodPostal's cost follows the emails actually sent, and contacts are unlimited at every volume, so a large list that is mailed rarely does not cost more for its size.

Setup is three steps on the homepage: connect the service with your own keys, create a campaign with AI or by hand, then send and track, with opens, clicks and bounces flowing back in real time and unsubscribes handled automatically.

Creating campaigns with AI or by hand

GoodPostal leans hard on AI drafting, but through tools the customer already uses rather than a model of its own. The homepage names ChatGPT, Claude, Claude Code, Codex, Cursor, Gemini, Gemini CLI "and anywhere MCP is available." A user describes the campaign in plain English, for example asking Claude to create the September newsletter, and GoodPostal returns a finished, on-brand email ready to review. Every draft is assembled from a library of professionally designed components, "so the first email already looks finished."

The final polish happens in a drag-and-drop editor, which the Amazon SES page says has 90 components. There is a public Components page and a Try the Editor link to test it before signing up. Campaigns can also be designed entirely by hand.

The AI integration runs on two pieces. An MCP server lets Claude, ChatGPT, Cursor or any assistant that speaks the Model Context Protocol work with the account, with the rule "AI drafts, humans confirm." A REST API exposes every dashboard action as an endpoint, with scoped keys per integration. The homepage adds that "Scoped keys, masked contact details, and approval gates mean an AI employee can run your email safely."

Sending, tracking and list hygiene

Campaigns can be queued for any date and time, and large sends are paced automatically to the connected service's send rate so that a big campaign does not trip throttling. Tracking covers deliveries, opens, clicks, bounces and complaints, and a click map shows where readers clicked. A/B tests are included.

GoodPostal presents reputation protection as a feature. Preflight checks on domains, webhooks and suppression lists run before every campaign, and the homepage says they "keep your email sending service from suspending you." Hard bounces and complaints suppress the contact automatically, unsubscribes are honored automatically, and the homepage states that "Your contacts stay encrypted and isolated." The footer links a DPA alongside the terms, privacy, refund and cookie policies.

Teams and agencies

Teams get separate workspaces for every brand or client, each with its own senders, contacts and analytics, and three roles: Owner, Admin and Member. The Amazon SES page lists team seats among the features. For a freelancer or agency running newsletters for several clients, each client's list and results stay apart while one account holds them all.

Working with Amazon SES

GoodPostal has a dedicated page for Amazon SES, which it calls "the cheapest serious way to send newsletters, at $0.10 per 1,000 emails on à la carte pricing". What SES lacks, the page says, is "any way to design a campaign, manage a list, or read the results", and GoodPostal is the hosted tool that fills that gap. With the customer's consent it sets up SES event notifications through Amazon SNS, so deliveries, opens, clicks, bounces and complaints reach the campaign analytics without the AWS console.

The page walks through the SES setup: new accounts start in a sandbox that only sends to verified addresses, so a newsletter needs production access first. GoodPostal offers a free SES Access Request tool that writes the production access support case "the way AWS wants to read it." The page also records that the SES free tier closed to new customers on July 21, 2026, that new SES accounts start on Amazon's Essentials plan at $0.16 per 1,000, and that one switch on the SES console's Pricing plan page moves an account to the $0.10 à la carte rate.

What it costs

GoodPostal itself is $19 a month plus $0.05 per 1,000 emails sent, with unlimited contacts. Delivery is billed separately by the sending service. The SES page gives two worked examples. One newsletter a month to 5,000 contacts comes to $19 for the software, $0.25 for metered sending and $0.50 for SES delivery, "$19.75 a month all-in", before taxes, attachment data, notification charges and add-ons. At 40,000 emails a month, the calculator shows $21 to GoodPostal ($19 plus $2 in sending) and $4 to Amazon SES, $25 a month in total. The same page puts a weekly newsletter to 10,000 people at about $4 a month in SES delivery.

The homepage and pricing page carry a calculator that compares GoodPostal plus a sending service against per-contact platforms at list sizes from 5k to 250k, with provider pricing it says was verified on 09-27-2026. A 14-day free trial needs no credit card, and the plan can be canceled anytime.

Free tools and other pages

The footer lists free tools, including an Email DNS Checker and an Email Price Index, pages for nonprofits and churches, a changelog, an Alternatives page and documentation. A Contact page sits in the main menu.

Who it suits and who it does not

GoodPostal suits a sender who already has, or is willing to set up, an account with one of the six named services or an SMTP server and wants a proper editor, list and reports on top of it without contact-based pricing: a newsletter writer with a large but lightly mailed list, a small business sending a monthly update, a church or nonprofit, or an agency keeping several clients in separate workspaces. It particularly suits people who already draft in ChatGPT, Claude or Cursor and want those drafts to become sendable campaigns under human approval.

It is a poorer fit for someone who wants a single vendor to handle delivery as well, since the customer must open, verify and look after its own sending account, including SES production access and notification setup.
