Brands can grow their email lists in a variety of ways. They can use opt-in forms on their website, social media profiles, and other digital channels to encourage visitors to sign up for their email list. These opt-in forms should be prominently displayed and offer an incentive for signing up, such as a discount or exclusive content. You can also use offline tactics, such as collecting email addresses at events or in-store, to add to their email list. Running contests or giveaways that require participants to sign up for their email list to enter offer a great incentive to opt-in. Finally, businesses can leverage their existing email list by encouraging subscribers to forward or share emails with their contacts, thereby growing the list organically. You can also utilize referral marketing and partnerships with other businesses to reach a wider audience and gain new subscribers. That said, it’s essential to grow your list organically and not purchase a mailing list with users that haven’t opted into receiving your emails.
