## Get help

Tell us what is happening. The form emails [support@trysincerely.com](mailto:support@trysincerely.com), and replies go to the address you give.

The [support page](https://trysincerely.com/support) asks for your name, work email, company or workspace, and what is happening. A sentence is enough.

## Email

Skip the form if email is easier. Write to [support@trysincerely.com](mailto:support@trysincerely.com).

## Documentation

The support page also carries the full documentation directory, so a question you can answer yourself does not need a reply. The pages are grouped as getting started, how the product works, how MCP works, and the API reference. Between them they cover audiences and address verification, writing and design approval, campaigns and the frequency cap, sending and vendor routing, landing pages, measurement and holdouts, suppression, billing and credits, team roles, the MCP tool catalog and its confirmation gate, and the workspace REST API.

[The documentation hub](https://trysincerely.com/docs) is the complete map, with every page named, described, and linked.
