Hey

Did you know personalization is one of the most powerful tools in marketing? Companies that excel at it generate 40% more revenue compared to average players.1

Netflix reorders its homepage around what you watch,2 Spotify builds you a new playlist every Monday,3 Amazon recommends products based on what you've already bought,4 and your TikTok For You feed is unlike anyone else's.5 All of these companies are using information they already have about each customer to personalize their experience.

You have the same kind of information about your subscribers. A first-time visitor, a longtime free subscriber, and a founding member each want something different from you, and when each one gets it, your publication grows.

For a long time, Substack didn’t support personalization. You could set a post to free or paid, and that was about it. One post and one email for everyone. But over the last year, Substack has shipped a ton of new features that have really leveled up personalization.

Today I'll go over all the personalization features Substack offers publishers. One of these features has never been documented anywhere by Substack, and it may have already greeted you by name at the top of this post. 🤫
