What is double opt-in?

Double opt-in allows you to require that contacts actively confirm their subscription before they are added to your email database.

You can create a double opt-in database, a double opt-in email or a double opt-in web form.

  1. A customer signs up to receive your emails via a web form.
  2. The customer is added to the double opt-In database in Acoustic Campaign in a pre opt-in state.
  3. A pre opt-in autoresponder is sent to the customer with a link to a double opt-In confirmation form.
  4. The customer's information is added to the double opt-In database and the contact is ready to receive emails.
  5. The welcome e-mail/subscription confirmation is sent to the customer (optional, depending on the set up).
Note: To remain GDPR compliant, contacts that remain in a pre opt-in state for longer than 30 days will be routinely removed from the database. To receive emails, contacts removed must restart and complete the full opt-in process.

Resend confirmation email

Acoustic Campaign has a safety net for contacts who accidentally misplace or delete the confirmation email.

If a contact loses the confirmation email, they can opt-in again and another confirmation email is sent to them.

In order to prevent malicious use of the resend function, limits are placed on the number of times a resend can occur.

The first time a contact attempts to opt into the database, a confirmation email is sent to that contact. The second time a contact attempts to opt in to the database a confirmation email is also sent to that contact. On all subsequent attempts to opt-in, Acoustic Campaign determines if the last attempt to opt-in was in the current calendar day. If it was, then an email is not sent. If the last attempt to opt-in was not in the current calendar day, then a confirmation email is sent.

By default, the resend restriction rules are turned on. However, the owner of the database or the Organization Administrator can switch these rules off at a database level. This is done by accessing the Settings for the database and clearing the Enable Pre Opt-in Confirmation Resend Restrictions check box.
