You just might not know how to talk about it.
But if you can learn to write better emails, you can:
Keep up a consistent email newsletter
Post on social super quickly
And hyper consistently
Be a better podcast guest
Be a better speaker
The best email subject lines solve problems
Which naturally lend themselves to great
And sometimes even entire website
TL;DR— if you can write an email fast, you can script and execute all of the above faster than you ever thought possible.
