Automate Gmail + Trello
The inbox most operations still start in. Boards and cards — simple enough to automate deeply. Put an agent between them and the hand-off stops being manual: it reads, decides, acts, and shows its work.
Inbox Triage is a ready-made agent built around Gmail; point its last step at Trello to finish this hand-off.
Automations teams run
Unlike field-mapping automation, the step in the middle is an agent: it can summarise, classify, judge and draft, not merely copy values from Gmail into Trello.
When a new email arrives in Gmail…
…an agent can create and move cards in Trello — after reading the context and deciding it should.
When a label is applied in Gmail…
…an agent can update checklists and labels in Trello — after reading the context and deciding it should.
When a thread goes unanswered in Gmail…
…an agent can summarise a board in Trello — after reading the context and deciding it should.
When a card is created or moved in Trello…
…an agent can send or draft a reply in Gmail — with the reasoning recorded in the run’s receipt.
When a due date approaches in Trello…
…an agent can apply labels and archive in Gmail — with the reasoning recorded in the run’s receipt.
When a checklist completes in Trello…
…an agent can extract attachments and fields in Gmail — with the reasoning recorded in the run’s receipt.
Gmail to Trello, in three nodes
Concretely: the gmail-api node on one side, a custom-api call to api.trello.com on the other, and an agent in between that can decline. Deciding not to write into Trello is a recorded outcome, not a silent one.

}Install Inbox Triage
Inbox Triage is a working agent built around Gmail. Install it, point its last step at Trello, and you have this hand-off without building it from an empty canvas.
Runs on your own machine · See what it does
Build it in AGNT
- Get AGNT Community Core. Free, local, no sign-up needed to run a workflow.
- Add both connections to the vault — Gmail takes one OAuth sign-in, Trello takes an API key pasted into the vault.
- Build the three nodes above, or start from a marketplace workflow and edit it. The agent in the middle is the part worth spending time on.
- Run it once with an approval gate in place. The receipt tells you what it read, what it concluded, and what it changed in Trello.
Gmail and Trello — common questions
Can I connect Gmail to Trello without writing code?
Yes. Gmail connects with one OAuth sign-in and Trello with an API key pasted into the vault, both from the local credential vault. You then describe the job in plain language — “when a new email arrives, create and move cards” — and the agent handles the rest.
How is this different from a field-mapping Gmail to Trello automation?
Mapping tools move data; this reasons about it. Rather than copying a field into Trello, the agent can weigh what arrived from Gmail, classify it against criteria you wrote in prose, draft something new, and act only when it is warranted.
Does my Gmail and Trello data leave my machine?
Your credentials stay in a vault on your own disk rather than in someone else’s cloud. The only calls made are the ones the workflow needs: Gmail, Trello, and your chosen model provider — which can be a local one.
What does a Gmail and Trello run leave behind?
A receipt: what was read in Gmail, which tools ran with which arguments, what the agent concluded, and what it wrote to Trello. Anything consequential can sit behind an approval gate so a person signs off before it happens.
