When it comes to building an audience that builds your freelance or consulting business, email remains the undisputed heavyweight champion.

Email was the original “killer app” — everyone uses it, and that’s why it’s been the absolute best channel for digital marketing and audience building. And yes, that’s still true in 2018.

The stats don’t lie. Every $1 spent on email marketing produces $44 in return, probably because 58% of adults wake up and immediately check their email (mostly on smartphones). And email remains 40 times better at converting people than Facebook and Twitter.

But that doesn’t mean that email marketing is the same as it’s ever been in years past. In fact, this is the one area where technology gives strategic content marketers an undeniable edge.

In other words, the money is still in your email list. But things have changed.
