To enrich your email list, one important thing you need to do is multiply the points of collection on your website. In addition to including subscription forms within your website, you can also implement pop-up forms on specific web pages to capture new subscribers. They are a very effective method of building your email marketing list.

But you need to make sure your pop-ups won’t be seen as an obstacle by the users, and that pop-ups won’t disrupt their experience. Be mindful of when to trigger them, and at which frequency. For example, you can display the pop-up after a certain delay, when the visitor scrolls a given percent of the way down the page, or when the user tries to exit the page (this is known as an exit intent pop-up). You can also decide to space out the number of times a pop-up appears. For example, you can show it only once per visitor instead of on every visit.
Note that, even if not mandatory according to the General Data Protection Regulation (GDPR), it’s still recommended to use double opt-in pop-up forms in order to make sure the user’s interested.
