01. IntegrationCommunicationProject Management

Turn incoming emails into Trello cards before a single task slips through

Inbound: never lose a request

Every proposed card or comment waits for your approval before it touches your board. You stay in control without slowing down.

02. Overview

Connect Gmail to Trello with an approval on every action

The Gmail to Trello automation on Rills watches your inbox and outbox, then proposes the right board action the moment something important happens. It is built for solopreneurs and small teams who live in email but need their project boards to stay current without constant copy-pasting.

When a trigger fires, Rills drafts the Trello action and puts it in your approval queue. You swipe to approve or reject from your phone. The system learns from your decisions over time, so the proposals get sharper. Approvals and workflow logic never cost a credit; you only spend when a real action runs on Trello.

The gmail trello integration covers four practical workflows: turning new emails into cards so nothing falls off your radar, adding sent emails as card comments to keep a full communication trail, parsing email content into card checklists for structured follow-up, and updating card status when you send a confirmation. Together they keep your Gmail inbox and Trello board in sync without manual effort.

03. Use cases

How do I connect Gmail to Trello?

Start a free Rills trial, then authorize both your Gmail and Trello accounts in the integrations panel. Pick a trigger, choose a Trello action, and your first workflow is ready in minutes. No code or technical setup is required.

How much does the Gmail and Trello automation cost?

Rills offers a free 14-day trial with no credit card required. Approvals and workflow logic are always free. You only spend credits when a real action executes in Trello, so exploring and testing workflows costs nothing.

Can it create a checklist on a Trello card from an email?

Yes. When a new Gmail message arrives, Rills can propose a checklist on a chosen Trello card, turning the email's action items into individual checklist entries. You approve the proposal before anything is added to your board.

Do I have to approve every single Trello action?

By default, yes. Every proposed action waits in your queue until you approve or reject it from your phone. Over time the system learns your preferences, and you can adjust automation confidence settings so trusted workflows can run with less friction.

What kinds of Trello actions can Gmail trigger?

The supported actions include creating a new card, adding a comment to an existing card, creating a checklist on a card, and updating card details or status. Each is tied to either a new incoming email or a sent email trigger in Gmail.

Will automation send or post anything without my review?

No. Rills proposes every action and waits for your explicit approval before anything is created or updated in Trello. Nothing posts to your board until you swipe to confirm, so your project data stays accurate and intentional.
