Unsubscribe & suppression

Suppression is managed by the platform. You don't maintain an unsubscribe list yourself — Elixpo Mails adds the right headers, handles opt-outs, and skips suppressed recipients automatically.

How it works

• Every non-transactional send carries List-Unsubscribe and one-click List-Unsubscribe-Post headers.
• When a recipient unsubscribes, they're added to the suppression list.
• Future non-transactional sends to a suppressed recipient are skipped, the delivery is logged as suppressed, and the trigger returns 200 { ok: false, status: "suppressed" }.
• Transactional sends (receipts, resets) are never suppressed.

In-body unsubscribe link

Use {{unsubscribe_url}} inside a template to render an in-body unsubscribe link, in addition to the header-based one-click option.

Managing the list

View and manage the suppression list on the product page. Suppression is scoped per product.
