How do I mark a Gmail message as read?

Short answer: You can mark as read in Gmail by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Gmail Mark as Read action to a workflow, map its 1 input from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Mark as Read.

What does the Mark as Read action do in Gmail?

Marks an email message as read by removing the UNREAD label. Used in auto-triage to clear inbox noise after handling.

What inputs does Mark as Read require?

Required: Message ID. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Gmail returns an error?

The run history shows the failed step with its input and the error message Gmail returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Mark as Read support batch operations?

Run Mark as Read inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Gmail's rate limits.
