Turn Trello card activity into Gmail emails — automatically

Project ManagementCommunicationReview from your phone

Most automations run blind. Rills lets AI propose each action — you review from your phone before anything executes.

What you can automate

Notify Clients When a Card Moves to 'Done'

When you update a Trello card's status to mark it as complete, automatically send a polished email to your client letting them know the deliverable is ready. No more manually drafting 'Hey, it's done!' messages — Trello triggers the update and Gmail fires off the email instantly.

Email Your Team When a New Task Card is Created

Every time a new card is created on a shared Trello board, automatically send an email to your team with the card details. Keep everyone in the loop without needing a separate Slack message or manual email — perfect for micro-teams where not everyone lives in Trello.

Draft Client Update Emails from Card Comments

When a new comment is added to a Trello card — such as a progress note or blocker — automatically create a Gmail draft summarizing the update. You get to review and personalize before sending, striking the perfect balance between automation and a human touch.

Label Incoming Emails Based on Trello Board Activity

Use Trello's board and list structure to trigger Gmail label creation and organization. When cards are listed on a specific board, create matching Gmail labels so incoming client emails are automatically sorted to mirror your Trello project structure.

Forward Project Updates to Stakeholders via Webhook

Set up a Trello webhook to watch for specific card or board changes, then automatically forward a formatted project summary email to key stakeholders. Great for solopreneurs managing client projects who need to send regular status updates without writing the same email repeatedly.

Create a Gmail Filter for Every New Trello Board

Whenever you spin up a new Trello board for a project or client, automatically create a corresponding Gmail filter so emails related to that project are tagged and organized from day one. Your inbox stays as structured as your Trello workspace.
