How SMS double opt-in works

SMS double opt-in can be triggered when Ometria receives an SMS opt-in from a contact via:

• Your preference centre
• An Ometria overlay
• API

When the double opt-in SMS is sent, an update displays in the contact's SMS consent log in the single customer view.

This consent log is updated again when the contact clicks the link and confirms their opt-in.

Before you begin

• Contact your Customer Success Representative to make sure your account is set up for double opt-in
• Define your opt-in rules per country

Time limits

Ometria won't trigger a double opt-in SMS if:

• your contact opted-in more than 10 days ago
• your contact received a double opt-in SMS in the last three days

These rules are to prevent spam.
