What is a preference center?

A preference center is a web page where recipients manage which emails they receive from a sender, instead of choosing only between staying subscribed and leaving entirely. It typically lists subscription categories, such as product updates or a weekly digest, and may offer a temporary pause next to a full unsubscribe. The unsubscribe link in a marketing email usually leads to it.

How a preference center works

Each recipient reaches the page through a link unique to them, so the page can show their current choices without a login. The recipient ticks or unticks categories and saves, and the sender's system updates the subscriptions that every later send reads. A campaign for a category then goes only to recipients who still hold it.

A full unsubscribe stays on the same page. Regulations require that a recipient can opt out of all commercial email, not only individual categories, so a page offering only topic choices is not enough on its own.

Many preference centers also ask for a reason when someone leaves, and some list recent emails so the recipient can recognise what they are subscribed to. Both give the sender information that an unsubscribe count lacks.

Preference center vs full unsubscribe

A preference center turns some unsubscribes into partial ones. A recipient tired of promotions but interested in product news can drop the first and keep the second, and a pause keeps a subscriber who is only busy for a while. Fewer full unsubscribes and fewer spam complaints are the main reasons senders build one.

The page only helps while leaving stays easy. A preference center that hides the unsubscribe option, asks for a login or takes several steps pushes recipients toward the spam button. Mail client buttons skip the page entirely: a list unsubscribe made from the inbox, and in particular a one-click unsubscribe, removes the recipient without opening it.

Best practices for preference centers

• Categories that match real sends: each option corresponds to a stream of mail the sender actually produces, named the way a recipient would recognise it.
• Current state shown: the page opens with the recipient's existing choices already set.
• One step to save: a single button applies the selection, and a full unsubscribe needs nothing more than an optional reason.
• Choices applied everywhere: every system that sends mail reads the same subscription data, so a topic dropped on the page is not re-added by a CRM sync.

A preference center works alongside a sunset policy. Recipients who state their interests keep getting the mail they want, while the sunset policy removes those who stopped engaging without ever visiting the page.

Preference center in Lettr

Lettr hosts a preference center, the Manage email preferences page, which every {{unsubscribe_link}} in a campaign opens through a signed per-recipient URL. It applies to marketing campaigns only, and transactional emails sent through the API or SMTP are not affected by anything a recipient does there. The page shows the contact's status, one checkbox per public topic plus any private topic the contact already holds, a pause for 30, 60 or 90 days, and up to the ten most recent campaigns the contact received.

Unticking a topic changes only that subscription, and consent is re-checked when a campaign's recipients are resolved and again for every batch. Unticking every box unsubscribes the contact from all marketing email after an optional reason, sets the status to unsubscribed and fires the unsubscribe.link_unsubscribe webhook event. A pause keeps the contact subscribed with a paused_until date, and campaigns skip them until that date passes.

The {{unsubscribe_link:redirect=...}} form sends the recipient to the sender's own URL after a full unsubscribe, and a campaign without the tag gets a minimal fallback footer before the closing </body> tag. The one-click unsubscribe triggered through the List-Unsubscribe header bypasses the page and unsubscribes immediately. The Subscription Topics page explains how public and private topics decide what the page shows.
