A follower on a marketplace or social platform is one algorithm change away from never seeing you again. An email address in your own list is yours to reach whenever you want.
Checkout is the easiest moment to capture an email — the customer is already engaged, and a simple opt-in costs you nothing.
Once you have a list, a simple automated sequence — a welcome email, a post-purchase check-in — keeps you in front of customers without manual effort.
Every customer who buys from a Buylib store is already added to your own audience list, with no extra setup. From there, you can build automated email sequences, run a campaign, or just export the list to use however you like — it's yours either way.
