What are the advantages of email over social media?

With email, you own the channel. On social media, you rent it.

A follower list on a platform is like renting a crowd in a city owned by Mark Zuckerberg. The algorithm decides who sees your message. Your email list is your own private ship's log. You can export it to any ESP and know your cargo will reach its destinations.

The reason this matters is that there is no algorithm filtering your reach. When you send an email to one thousand subscribers, it lands in one thousand inboxes. A social post might only reach fifty.
