Turn Important Emails into Trello Cards Without Lifting a Finger
Connect Gmail and Trello to stop copying tasks by hand and keep your project boards in sync with your inbox.
Gmail + Trello integration
Gmail and Trello are two of the most widely used productivity tools out there, yet most teams still move information between them manually. When an important email arrives — a client request, a bug report, a sales lead — someone has to stop what they're doing, open Trello, and create a card by hand. Integrate Gmail with Trello through tray.ai and that whole process runs itself, so nothing gets buried in the inbox and your boards actually reflect what's going on.
Email is still where external requests, approvals, and action items show up first. Trello is where your team does something about them. Keeping those two systems in sync by hand is slow, error-prone, and gets harder as volume grows. A Gmail–Trello integration automatically routes the right emails into the right boards, lists, and cards — complete with labels, due dates, attachments, and assignees. Your team gets full visibility into incoming work without toggling between inbox and project board all day, and managers can trust that every committed action item is actually being tracked.
Automate & integrate Gmail + Trello
Automating Gmail and Trello business processes or integrating data is made easy with Tray.ai.
Use case
Convert Client Request Emails into Trello Cards Instantly
When a client emails a request to a shared inbox or a specific address, tray.ai parses the email, pulls out the sender, subject, and body, and creates a fully populated Trello card in the right client project board. The card gets assigned to the relevant team member and dropped into the correct list based on request type or priority. No more client requests quietly dying in a crowded inbox.
- Every client request becomes a trackable Trello card within seconds of arrival
- Cards are automatically assigned and labeled, cutting triage time
- Teams get a clear audit trail linking email conversations to project tasks
Use case
Create Support Tickets on Trello from Inbound Support Emails
Customer-facing teams managing support through Gmail can automatically generate a Trello card for each new support email, routing it to a dedicated board with severity labels and due date rules already applied. Reply threads get appended as card comments, so the full conversation history lives right alongside the task. It's a lightweight ticketing experience without paying for a dedicated helpdesk tool.
- Support requests are never lost in individual inboxes
- Severity and priority labels are applied automatically based on email keywords
- Full email thread history is preserved directly on the Trello card
Use case
Add Trello Cards for Sales Leads from Gmail
When a new inbound lead emails your sales address, tray.ai creates a Trello card in your sales pipeline board, populated with the prospect's name, company, and message. The card lands in a 'New Leads' list and gets assigned to the next available sales rep using round-robin logic. Your pipeline board stays current without anyone having to babysit it.
- Leads are captured in the pipeline board the moment they arrive
- No manual data entry required from the sales team
- Round-robin assignment keeps lead distribution fair
Use case
Notify Gmail When a Trello Card Status Changes
When a Trello card moves from one list to another — say, from 'In Progress' to 'Ready for Review' or 'Done' — tray.ai can automatically send a Gmail notification to the relevant stakeholder or client. External parties stay informed without needing Trello access. You can customize which list transitions trigger emails and what the message says.
- Clients and stakeholders get timely progress updates automatically
- Teams spend less time writing manual status update emails
- Updates go out consistently across all project milestones
Use case
Attach Gmail Email Threads to Existing Trello Cards
When a reply comes in on a thread already tied to an open Trello card, tray.ai appends the new message as a comment on that card, keeping all relevant communication in one place. This works especially well for teams that run conversations through Gmail but treat Trello as the source of truth for project status. Context stops falling through the gap between inbox and board.
- All email context lives on the Trello card where the work is happening
- Team members can review full communication history without leaving Trello
- No more manually copying email content into cards
Use case
Create Recurring Task Cards from Scheduled Gmail Digests
Operations and project management teams can use tray.ai to parse scheduled digest or report emails in Gmail and automatically generate recurring Trello cards for the action items they contain. A weekly metrics email, for example, can trigger review task cards assigned to the right team leads. Recurring operational tasks get tracked consistently without anyone having to remember to set them up.
- Recurring tasks are created reliably without depending on human memory
- Digest email content gets translated into structured, assignable Trello cards
- Teams save real time on weekly and monthly operational setup
Challenges Tray.ai solves
Common obstacles when integrating Gmail and Trello — and how Tray.ai handles them.
Challenge
Filtering Signal from Noise in a Busy Inbox
Gmail inboxes can take in dozens or hundreds of emails a day. Triggering a Trello card for every one of them would bury your boards fast, and it's genuinely hard to tell which emails should become tasks and which should just be read.
How Tray.ai helps
tray.ai's workflow builder lets teams define precise trigger conditions for Gmail — sender domain, subject line keywords, label presence, recipient address — so only the emails that actually matter generate Trello cards. Conditional logic within the workflow can then route those emails to different boards, lists, or assignees based on content, so every card created has a reason to exist.
Challenge
Mapping Unstructured Email Content to Structured Trello Fields
Emails are free-form text. Trello cards have specific fields: titles, descriptions, labels, due dates, assignees. Translating one into the other by hand is tedious, and basic automation that dumps a raw email body into a card description usually produces something nobody wants to read or act on.
How Tray.ai helps
tray.ai's data transformation and text parsing tools let teams pull specific information out of email bodies — deadlines mentioned in the text, project names, priority indicators — and map them to the right Trello card fields. Teams can also set up templates for common email formats, so the resulting cards come out clean, consistent, and ready to work from.
Challenge
Keeping Bidirectional Sync Consistent Without Duplication
When both Gmail and Trello are updating at the same time, bidirectional integrations can create feedback loops: a card update triggers an email that triggers another card update. The result is duplicate cards, redundant notifications, and a team that stops trusting the integration.
How Tray.ai helps
tray.ai includes workflow controls that break feedback loops through conditional checks, deduplication logic, and state tracking. Workflows can verify whether a card already exists for a given email thread before creating a new one, and notification workflows can be scoped to specific list transitions that exclude automated movements, keeping everything clean.
New Gmail Email to Trello Card
Gmail 
Trello Automatically creates a new Trello card whenever a matching email arrives in Gmail, using the email subject as the card title, the body as the description, and the sender's address as a label or custom field.
Gmail Label Applied to Trello Card Creator
Gmail Trello When a specific label is applied to a Gmail email — such as 'Action Required' or 'Client Request' — tray.ai automatically creates a corresponding Trello card in the right board. Labeling an email in Gmail doubles as task creation in Trello.
Trello Card Due Date Reminder via Gmail
Trello Gmail Automatically sends a personalized Gmail reminder to the card assignee when a Trello card's due date is approaching, so deadlines don't get missed and you're not chasing people down manually.
Trello Card Completion Notification to Gmail
Trello Gmail Sends an automatic Gmail notification to a client or stakeholder when a Trello card moves to the 'Done' list — a professional, timely project update with no manual outreach required.
Gmail Attachment Saver to Trello Card
Gmail Trello When an email with an attachment arrives in Gmail matching defined criteria, tray.ai saves the attachment to cloud storage and adds the link to the relevant Trello card, so project files don't end up scattered across inboxes.
Daily Trello Board Digest Email via Gmail
Trello Gmail Compiles a daily summary of Trello activity across selected boards — cards created, updated, completed, and overdue — and emails it to designated recipients via Gmail each morning.
