Opt-In

What is the meaning of Opt-In?

Subscribers may be asked to fill out a certain signup form before joining an email list. This is called opting-in. Opt-ins are express consent from recipients that allow senders to email them. It is best to use a “double opt-in,” i.e., the potential recipient fills out the form first and then confirm the subscription to your list.
