Just think of the number of times you’ve signed up for a newsletter or free trial and given permission to be marketed to.
We all complain about spam and cluttered inboxes, but have a think about those emails that you do notice and open. And the ones you delete? Even with zero engagement those brands will have reminded you about them.
Email is old school but you know what? It works.
And remember this too: when you’re growing an email list you’re building up a database that has a real, tangible value.
