Best Practices
Don’t use more than 2 input fields in a pop-up

Pop-ups with two input fields convert (3.31%) more than 3x better than pop-ups with three input fields (1.08%).

Avoid displaying the pop-up in full-screen format

This annoys customers and reduces conversions. Small pop-ups convert 23,8% better than full screen ones.

Add images to collect email addresses

Pop-ups with images convert 4.3% of visitors. At the same time, they only convert 2.63% when no images are present.

Add an opt-out button

Pop-ups with two action buttons (where the second one is an opt-out button) convert 14.34% higher.

Use a countdown timer

Pop-ups with a countdown timer convert better than forms without it by 112%.

Use multiple step pop-ups

Pop-ups with two steps get 76% more subscribers willing to share mail.

Use the sniper link soon

Adding the sniper link allows you to guide them to exactly the right email so that they return to your website immediately
