What’s the Difference Between Single Opt-In and Confirmed Opt-In?

Single opt-in adds users instantly, while confirmed opt-in requires email verification before adding them to your list. Click to compare both methods and decide which is right for you.

With single opt-in, users are subscribed to your email list as soon as they submit a form. This is fast and simple, but opens the door to fake emails and lower-quality leads.

Confirmed opt-in (also called double opt-in) adds a step: users must click a link in a confirmation email. This ensures the address is real and that the user actively wants your content — boosting engagement and legal compliance.

Gleam integrates with providers that support both flows, so you can choose the method that fits your compliance and marketing goals.
