What the Unsubscribe Link Generator does

An unsubscribe link is a one-click opt-out URL or mailto address carrying a subscriber identifier, which is what CAN-SPAM, GDPR and the List-Unsubscribe header expect.

Methodology and formula

The tool appends the subscriber email or token to your unsubscribe endpoint as an encoded query parameter, or builds a mailto address with an unsubscribe subject line.

Worked example

Inputs: Endpoint https://example.com/unsubscribe, subscriber jane@example.com
Result: https://example.com/unsubscribe?email=jane%40example.com

A footer link that removes the subscriber in one click with no sign-in.

When to use this tool

Pair the unsubscribe link generator with the short link generator for a tidy shareable address, or the QR code generator when the link has to work on print.

How the link is built

Things to watch out for

An unsubscribe link must work without a login and process the request within ten business days to stay compliant.

Frequently asked questions

Is an unsubscribe link legally required?

For commercial marketing email in most jurisdictions, yes — including CAN-SPAM and GDPR-covered mail.

Should I use a token instead of an email?

A signed token is safer because it prevents anyone from unsubscribing another person by guessing addresses.

Is this link generator free?

Yes. Every generator on BusinessTools.Online is free, needs no signup, and builds the link in your browser.

Do you store the links I create?

No. The link is assembled locally in your browser and never sent to or saved on our servers.
