Your marketing email archive. In the AI tools you already use.

MCP is a standard way for supported AI tools to access external information. In PromoStash, it lets your connected client search your private marketing email archive and retrieve saved messages. You do not need to copy an entire email thread into a chat every time you want to reference it.

ChatGPT, Claude, Cursor, and other tools offer different ways to connect external services. Availability, authentication methods, and subscription requirements depend on your client. Use the instructions on your account’s MCP setup screen and check your client’s current documentation. A client with remote MCP support and a compatible authentication method is required; not every client or plan works identically.

Ask your client to find Black Friday emails from a named brand, retrieve launch emails from a collection, or compare subject lines in a selected date range. These are questions for your external AI tool—not automated analyses running inside PromoStash. If your archive has only a few messages, the answer can only draw on those messages.

The connection provides six read-only tools: search_emails, get_email, list_brands, get_brand_emails, list_collections, and get_collection_emails. Searches can narrow by brand and date. Results are paginated, with up to 50 items per page, so a client can retrieve relevant references without requesting the entire library at once.

Email retrieval returns the subject, sender, date, brand, text, and links instead of a giant HTML document. Text responses are capped at 20,000 characters per chunk; the client can request the next chunk of a longer email. Images are not converted into searchable text, so image-only emails may provide little material for your client to analyze.

Connections are authenticated and scoped to your account. Use the supported authorization flow or an access key from your MCP setup screen. Keys default to read-only; collection writes require opting in. Never share a key publicly or paste it into a prompt. With explicit collection write permission, five additional tools can create, update, and delete collections and add or remove their emails. Deleting a collection keeps its emails. The tools cannot send emails or delete archived emails. Collections help organize a request, but do not limit authorization to one collection.

When a client retrieves an email, its contents become available to that client. Review the external provider’s data handling and account settings before connecting. Incoming emails are untrusted material: instructions inside them are content to inspect, not commands the AI should follow. Verify important conclusions against the saved source email, especially when an answer goes beyond what the archive contains.
