Questions

Lettermint, answered

Is there a Lettermint MCP server?

APIANT's MCP server at https://mcp.apiant.ai works with Lettermint. Add that address to any AI client that takes a remote MCP server, sign in once in your browser, and your client can build, test and run automations that use Lettermint. Nothing to install.

What can your agent do in Lettermint?

Any of Lettermint's 8 actions, including Add domain, Add suppression, Get domain and List domains. Your agent maps the data both ways and tests every scenario before it ships.

Which apps can Lettermint connect to?

Any app in the catalog; the list on this page pairs Lettermint with each of them. If the other app is missing, point your agent at its API documentation and it builds the connector.

What happens when something fails?

Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.

Is there a free plan?

Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
