How to unsubscribe from Seamless emails

Seamless unsubscribe comes down to one control: the unsubscribe link in the footer of the promotional email itself. Seamless runs on the Grubhub platform - the two brands merged back in 2013 and share a single privacy policy - and that policy names the in-email link as the way to stop promotional messages. There is no separate marketing-preferences dashboard to hunt for. Service emails such as order confirmations and account notices are excluded from any opt-out and keep flowing when you order.

Method 1: the in-email unsubscribe link

1. Open a recent Seamless promotional email - a promo code, perks reminder, or restaurant recommendation.
2. Scroll to the footer and click the unsubscribe link.
3. Follow the confirmation step on the page that opens. The link is tokenised, so you do not need to sign in.

Because this is the mechanism Seamless itself documents, start here rather than digging through account screens looking for a toggle that does not exist. Give it a day or two to propagate - a promo already queued when you clicked can still slip through once.

Method 2: your mail client's native button

Seamless marketing mail ships with the List-Unsubscribe header, which means Gmail places an Unsubscribe shortcut right next to the sender name and Apple Mail shows its unsubscribe banner. Clicking it fires the same opt-out as the footer link with less scrolling.

Method 3: texts and push

Order-related and promotional texts stop when you reply STOP to the sending number - the privacy policy calls this out explicitly. App push notifications have their own toggles inside the Seamless app settings and are untouched by any email opt-out, so switch those off separately if needed.

The sibling-brand catch, and verifying it stuck

The most common surprise after a Seamless opt-out is mail from Grubhub: same platform, same parent company, different sender lists. Your Seamless unsubscribe covers Seamless addresses only, so a Grubhub perks blast a week later is expected behaviour, not a failed opt-out. Genuine failures do happen though - reactivation lists in particular. Rather than assuming success, ClearMyInbox revisits the Seamless sender about four weeks after your opt-out and reports whether the mail genuinely dried up or needs another pass.

Mailbox-level fallback

Should promos persist, take it out of Seamless's hands. In Gmail, filter the specific promotional sender to Skip Inbox or Delete while leaving the rest of seamless.com alone so confirmations arrive. In Outlook, Sweep the address or add it to your blocked senders list under Junk email options.

What stays no matter what

Account verification messages, order confirmations, receipts, delivery updates, and security notices are service communications. The privacy policy states you cannot opt out of them - but they are order-triggered, so they only show up when you actually use Seamless.

Zooming out to the whole category

Delivery platforms are serial inbox offenders, and DoorDash is usually sitting a few rows above Seamless in the same inbox. For the complete sweep-them-all approach, read how to stop food delivery emails.
