Email marketing is still relevant in 2021, and it will likely continue to be in the years to come. Why? Because you can monetize your list of contacts.
With email marketing, in contrast to Facebook Custom Audiences or Google Ads targeting, you don’t have to build your business on rented land. Maybe Facebook will turn off the Custom Audiences feature tomorrow, or Google will restrict targeting options. If you build your business exclusively on third-party systems, you run the risk of losing revenue sources.
That’s why your email list is a treasure. The contacts are your contacts, and you can contact them whenever you want (until they unsubscribe) — for free.
Drawing on my own experience with email marketing, here's my advice on who it is for, what tools you can use and how to get started.
