How do I resubscribe to an email I unsubscribed from in Gmail?

Last reviewed: September 28, 2026 · Markdown version

Sign up again with the sender, usually on their website or in your account settings there, then tell Gmail the mail is wanted by marking the next message "Not spam". Gmail has no resubscribe button, because unsubscribing is a request that went to the sender, and only the sender's list can take you back. Gmail's part is smaller: after an unsubscribe it sends that sender's new mail to Spam, and that is the bit you undo on your side.

What Gmail's Unsubscribe actually did

Gmail's own description of the aftermath, from its Manage subscriptions page: "When you unsubscribe from a sender, any new emails from them go to your spam folder. A banner on these emails explains why the emails are in spam." The same page's fix is one click: "To move emails from the sender back to your inbox, click Report not spam." (Manage your subscriptions in Gmail, read 28 September 2026). Google's spam page names the banner: "You tried to unsubscribe from this sender", and says what to do: "If you don't want these emails sent to Spam, remove their email from Spam" (Report spam in Gmail, read 28 September 2026).

So there are two separate things to put back: your place on the sender's list, and Gmail's routing of that sender. Undoing one does not undo the other.

Is there an undo in Gmail?

Not in the sense of cancelling the request. Google's two unsubscribe pages, Unsubscribe from an email and Manage your subscriptions in Gmail, describe how to unsubscribe and what happens next; neither describes a way to reverse the request once it is sent (Unsubscribe from an email, read 28 September 2026; Manage your subscriptions, same date). When the documentation is silent we say so rather than guess: we found no Gmail control that re-subscribes you.

Two details from those pages make recovery easier than it sounds. Unsubscribing is not instant, "it may take a few days for you to stop receiving emails from the mailing list", so a quick change of mind may never have taken effect. And an unsubscribe from inside one email "might only unsubscribe you from a single mailing list from the sender", so other lists from the same company may still be arriving.

Getting back on the list

Go to the sender, not to Gmail. Use the newsletter sign-up box or the email-preferences page in your account on their site, whichever they have. Signing up again is the resubscribe.
Look for the confirmation. If they send one, check Spam first, because of the routing described above.
Mark it Not spam. On a computer: open Spam, tick the message, click Not spam. Per Google's spam page, after you remove an email from Spam, "future emails from that sender won’t go to Spam".
Optional: add them to Contacts or make a filter. The same page says adding a sender to Google Contacts stops Gmail sending their messages to Spam, and a filter can label a sender's mail as important. How filters work.

Those steps are ours; the sender's own site decides what signing up again looks like.

If you blocked them instead

Blocking is a different switch, and it is stickier. Google: "When you block a sender, even when you remove their emails from Spam, Gmail still automatically identifies their emails as spam" (the Report spam in Gmail page). You have to unblock first: open one of their messages, then More, then Unblock, or use Settings, Filters and Blocked Addresses, then "Unblock selected addresses". After that, "all future emails from them go to your inbox" (Block or unblock an email address in Gmail, read 28 September 2026). Blocking never unsubscribed you, so there may be nothing to resubscribe to.

If you are unsure about a sender, a filter that archives it is easier to reverse than an unsubscribe. The trade-offs between the two are on Is it OK to unsubscribe from emails?, and the unsubscribe routes themselves on How to unsubscribe from emails in Gmail.
