# Popups
Spark has two types of **Popups**: Promo popup (with optional newsletter sign-up) and Age Verification. Customize your popups with custom colors, images, and promotional text.
## Promo (Sign Up)
The regular **Popup** can be used for promotions as well as a newsletter signup.
> Newsletter subscribers are added to your "accepts marketing" [Customers](https://shopify.com/admin/customers?query=\&accepts_marketing=1) list.
