Turn Trello card activity into Gmail drafts and notifications, reviewed before they send

Outbound: keep stakeholders informed

Every automation Rills proposes waits for your approval before touching Gmail. You stay in control of every draft, reply, and notification without babysitting the workflow.

02. Overview

Connect Trello to Gmail with an approval before every action

The Trello Gmail integration on Rills turns card activity into ready-to-send Gmail drafts and email notifications without anything leaving your outbox unseen. It is built for solopreneurs and small teams who use Trello to manage work and Gmail to communicate with clients, stakeholders, or collaborators.

When a card event fires on Trello, Rills drafts the corresponding Gmail action and pauses for your review. You approve or reject from your phone with a swipe. Rills learns from your decisions over time, so the suggestions get sharper. Approvals and logic steps are always free; you only pay when a real Gmail action executes.

With trello to gmail automation, you can draft a stakeholder email the moment a card is created, reply to an email thread when a card comment is posted, notify a newly assigned member with card details, or draft a progress update when a checklist item is checked off. Every one of those actions sits in your approval queue first.

03. Use cases

Common questions about connecting Trello to Gmail

How do I connect Trello to Gmail?

Sign up for a free Rills trial, then authorize both your Trello and Gmail accounts from the integrations page. From there, pick a Trello trigger and a Gmail action, and Rills will propose automations as soon as card events start firing. No code required.

How much does the Trello to Gmail integration cost?

You get a free 14-day trial with no credit card required. Approvals and logic steps are always free, no matter how many you use. You only pay when a real Gmail action, such as sending an email or creating a draft, is actually executed.

Can Rills automatically reply to an email thread when a Trello card gets a comment?

Yes. When a comment is posted on a Trello card, Rills can draft a reply to the linked Gmail thread and hold it for your approval. Once you swipe to approve, the reply sends. Nothing goes out without you reviewing it first.

Do I have to approve every single Gmail action, or can it run automatically?

By default, every proposed action waits for your approval. As Rills learns your preferences from past decisions, you can choose to let trusted action types run without a manual review. You stay in control of which actions require a sign-off and which can proceed.

What Trello events can trigger a Gmail action?

The curated pairings cover four triggers: a new card being created, a comment added to a card, a member assigned to a card, and a checklist item marked complete. Each one can fire a corresponding Gmail action such as a draft, a reply, or a direct email send.

Will Rills send emails from my actual Gmail account?

Yes. Rills connects to your Gmail account via secure OAuth and executes approved actions on your behalf. Drafts appear in your Gmail drafts folder, sent emails come from your address, and replies thread correctly. You are always the sender.
