GoodPostal in ChatGPT

GoodPostal is in ChatGPT's plugin directory. Install it once, sign in with your GoodPostal account, and build branded emails, manage contacts, and prepare campaigns by chatting. There are no keys to copy.

What the plugin includes

The plugin gives ChatGPT a curated set of 64 tools chosen for conversational use. Setup and delete actions stay in the GoodPostal dashboard, so a chat can build and prepare, but the riskier account changes remain in your hands.

Install GoodPostal

1. 1

   Open the GoodPostal plugin

   Go to the GoodPostal plugin page in ChatGPT, or open Plugins in the ChatGPT sidebar and search for GoodPostal.
2. 2

   Install it

   Click Install plugin.
3. 3

   Sign in and authorize

   ChatGPT sends you to GoodPostal. Sign in, pick the workspace you want on the Authorize Application screen, and click Authorize. There are no keys to manage.
4. 4

   Start chatting

   Open a new chat, type @GoodPostal, and ask for what you need.

What the chat can do

Once installed, type @GoodPostal in any chat and ask in plain language. ChatGPT calls the right tools for you. For example:

• "Design a spring fundraising email in our brand colors."
• "Add everyone in Oregon to a group called Portland Donors."
• "Send a test of my latest template to me."
• "Show me how last month's newsletter performed."

Some replies render as interactive cards inside ChatGPT, such as a template preview or a campaign review summary, so you can see the result without leaving the chat.

Two safeguards worth knowing

Sends always need your approval

ChatGPT can draft a campaign, choose the audience, and check that everything is ready, but it cannot send, schedule, or queue it. When a campaign is ready, GoodPostal returns a review link. You open that link in the GoodPostal dashboard and approve the send yourself. Nothing goes out from a chat.

Contact details stay masked

When ChatGPT looks up contacts, GoodPostal returns a privacy-safe display name and a masked email, for example "Chris D." and "da******47@gm**l.com". Full last names, full email addresses, phone numbers, and street addresses are never sent to the chat. Filtering still runs against the complete record, so you can target by state, city, or subscription status without exposing anyone's personal information. This masking is a deliberate feature, not a limitation.

Troubleshooting

• Cannot find GoodPostal. Use the GoodPostal plugin page directly. On a ChatGPT Business, Enterprise, or Edu workspace, ask your admin to make the plugin available.
• No workspace to choose. The connection needs an active GoodPostal workspace (trial or paid, including Nonprofit); a frozen or expired workspace will not appear. Open Billing in the GoodPostal sidebar, then reconnect.
• A tool says you cannot make changes. Reading is always allowed, but creating or editing needs write access, which ChatGPT requests on your behalf. Disconnect GoodPostal in ChatGPT's Plugins settings and connect it again so it asks for write access afresh. If it still fails, check that your seat in that workspace is not a viewer, since viewers cannot make changes however the plugin is authorized.
• Asked to sign in again. Your authorization expired. Disconnect GoodPostal in ChatGPT's Plugins settings, connect it again, and approve.
