While search might take care of some of the bottom of the funnel traffic that number is capped by limited monthly volume.
So it’s vital to also have a strong top of the funnel game.
What Buttondown needs to do is push much harder on the growth loop pedal. A product like this is lucky enough to have the opportunity to leverage that.
Imagine this. You follow someone you like and trust. You subscribe to their newsletter. When you receive an issue you see they’re using Buttondown. The fact that someone you admire is using it not only introduces you to a new tool but also carries a lot of social proof. If they’re using it it must be good. Some of their subscribers might start using it too gradually exposing more and more people to the same growth loop.
So the number one goal for Buttondown should be growing that number as much as possible.
Not with just anyone but with authors whose audiences match their ideal customer profile.
The most efficient way to scale this is to manually find those authors and offer them some kind of partnership deal like letting them use the product for free.
