What it is
With double opt-in, a new subscriber first gets an email and confirms that they want to subscribe. Until they do, they don't get your emails.
Your list stays clean: typos and fake addresses never make it on.
It belongs to your email provider, so OptiMonk shows it only for providers that accept it per campaign, like CleverReach, in the integration's Settings step.
Key benefits
Every address is confirmed.
Use the confirmation email to introduce your brand or send an offer.
Statistics show a 7% lower unsubscribe rate than with single opt-in.
How it works

Step-by-step setup lives in the Help Center guide.
Subscribers are added to your list as soon as they sign up.
In the campaign's Integrations tab, when you add the integration.
No. OptiMonk shows it only for providers that accept it per campaign.
