Popups can be helpful for growing an affiliate email list when used the right way. They are those small boxes that appear on a website, asking visitors to sign up. To make them work, it helps to offer something useful, like a free download, discount, or helpful tip. The message should be simple and the form should be short, asking only for what’s needed. Some websites show the popup after a few seconds, while others wait until the person scrolls down or tries to leave. This makes sure the visitor isn’t pushed too early. Popups should not block the entire page or be hard to close, or they might annoy people. If used well, they can help turn website visitors into email subscribers. What kind of offer would you consider adding to a popup that can make visitors want to leave their email address before leaving the page?
