# Unsubscribe links & staying compliant

> Why every email needs an unsubscribe link and how to add one.

---

Every marketing email you send must let the recipient opt out with one click. It's a legal requirement in most countries and it protects your deliverability.

## Add the unsubscribe link

In the template editor, add a link and set its target to the unsubscribe merge tag (often shown as `{{unsubscribe_link}}`). HexaFloww turns it into a working per-recipient link at send time.

Most templates put it in the footer along with your business name and address.

> [!WARNING]
> The campaign wizard warns you when a selected template has no unsubscribe link, but it won't stop you sending. Add the link — an email without one is far more likely to be marked as spam.

## What happens on unsubscribe

When someone clicks it, they're added to the email [suppression list](https://hexafloww.com/docs/contacts/consent-suppression.md) for that project immediately, and excluded from every future email send. You don't need to do anything.

## Good practice

- Include your real business name and a postal address in the footer.
- Don't make people log in or fill a form to unsubscribe — one click is the standard.
- Honour opt-outs that arrive by other means (reply, phone) by adding them to the suppression list by hand.
