A simple UI for transactional email
Easily assemble a UI on top of Sendgrid, Mailgun, or whatever ESP you're using to reach your customers fast
Native SendGrid integration
Retool integrates natively with SendGrid – you can send transactional email with personalizations, look at your contacts and lists, and work with marketing templates. And if you're using another ESP, Retool easily connects to any REST or GraphQL compatible endpoints.
Simple custom UIs
Retool ships with all of the building blocks you need to assemble a useful UI on top of your ESP APIs – pull your users into a table, adjust email details via a rich text editor, and connect your `POST` request to a button.
Integrate with your user data
Retool connects to 40+ data sources, so you can bring in your user data wherever it is – Postgres, MongoDB, Firebase, Snowflake, you name it.
From startups to Fortune 500s, the world's most effective teams use Retool to build custom business software. Our customers↗
