Check frequency
The percentage of people who willingly subscribe or opt in to receive emails from a particular sender or marketing campaign.
Why it is important
This percentage is crucial for building a responsive and engaged subscriber base. Tracking opt-ins guides marketers in evaluating the appeal of campaigns and refining strategies to attract quality subscribers.

It contributes to list health, deliverability, and overall campaign success, ensuring that communication reaches an interested audience.
(Opt-Ins / Number of visitors or impressions) * 100
Calculation example
If your website had 1,000 visitors, and 200 of them subscribed to your newsletter, the Opt-in Rate would be (200 / 1,000) * 100 = 20%
