How to unsubscribe from Trello emails
Working out how to unsubscribe from Trello emails means turning two different dials. The quickest win: set email notification frequency to Never on your account page at trello.com/u/my/account, which kills the card-by-card activity mail. Marketing and tips email is a separate machine - it belongs to your Atlassian account, not to Trello, and switches off in the Atlassian Email preferences center. Miss either dial and some portion of the mail keeps flowing.

Dial 1: board activity emails
- Sign in and open trello.com/u/my/account.
- Find the email notification frequency control and pick Never, Periodically (an hourly digest), or Instantly.
- Below the frequency, deselect entire categories if you prefer surgical cuts: comments, due dates, removal from cards, attachments added, cards created, moved, or archived.
Two caveats from Atlassian's own documentation. First, these preferences apply only to activity on boards, lists, and cards you watch - so unwatching a hyperactive board is often the better fix than muting your whole account. Second, a core set of emails ignores the setting entirely: invitations, direct @mentions, being added to a card, and being made an admin will always reach you.
Dial 2: marketing mail via your Atlassian account
Trello product news, tips, and promotional email is sent under Atlassian's roof. Click your avatar, choose Account settings → Email → Email preferences center, and deselect the categories you are done with. Because that one screen covers Jira and Confluence too, we keep a dedicated walkthrough of it - including the trap in the Unsubscribe all button - in the Atlassian unsubscribe guide. The footer link in any Trello marketing email reaches the same consent record if you would rather start from the message in front of you.
What no setting will silence
Beyond the always-on invitations and mentions above, account-level mail - password resets, billing for paid Workspaces, security notices - is transactional and untouched by both dials. That is the correct behaviour: you want the board chatter gone, not the email telling you someone signed into your account.

Clean up the whole project-tool shelf
Teams that evaluated Trello usually evaluated its rivals in the same week, which is how Asana and Airtable onboarding sequences end up sharing your inbox years later. A single ClearMyInbox scan surfaces every one of them for a bulk opt-out - the pragmatic answer to tool-sprawl email overwhelm.
Still hearing from Trello?
Diagnose by sender and subject. An email describing card movement means a watched board slipped through - unwatch it or revisit the frequency setting. A tips-and-tricks newsletter means the Atlassian preference center still has a category ticked. An invitation or @mention is working as designed and has no off switch. Because misdiagnosis here is so common, ClearMyInbox circles back about a month after each unsubscribe and reports whether the sender genuinely stopped, so a half-turned dial shows up as evidence rather than a vague feeling that Trello never listens.

The mailbox-side backstop
If a residual stream annoys you faster than you can find its dial, route it away at the mailbox: a Gmail filter on the exact Trello notification address set to Skip Inbox, or Outlook's Sweep on the same sender. Filter narrowly rather than blocking the domain - invitations and security mail ride the same infrastructure.
Frequently asked questions
How do I stop Trello emailing me about every card?▾
Open your account settings at trello.com/u/my/account and set the email notification frequency to Never. Periodically batches activity into an hourly summary if you want fewer emails rather than none.
What do Never, Periodically, and Instantly actually mean?▾
Never sends no activity emails at all. Periodically sends an hourly digest of accumulated notifications. Instantly emails you shortly after each notification lands in Trello.
Why do I still get Trello emails after choosing Never?▾
A handful of notifications always send by design: board and Workspace invitations, direct @mentions in comments, being added to a card, and being made a board or Workspace admin. The frequency setting cannot suppress these.
Where do Trello marketing and tips emails switch off?▾
Not in Trello. They are governed by your Atlassian account: click your avatar, open Account settings, choose Email, then Email preferences center, and deselect the categories you no longer want.
Can I silence one noisy board without going quiet everywhere?▾
Yes - stop watching it. The email frequency setting is account-wide, but activity emails only cover boards, lists, and cards you watch, so unwatching the loud board cuts its email at the source.
Does closing my Trello account stop the emails?▾
It stops board activity, but marketing consent lives on the Atlassian account layer, so visit the Email preferences center too - or use the unsubscribe link in the next marketing email that arrives.
