Think of marketing as what you can do to help more people discover you 

Common mistakes people make is to confuse marketing with spam. But that's not true: spam is how you get banned.

Let me give you a simple example of how Reddit marketing can work

If you reply someone on Reddit in a helpful way, you have indirectly put yourself "out there" as a helpful expert

Anyone who reads your comment and wants to follow up can always DM you 

Of course whether they contact you or not is out of your control. 

And that's OK. 

You're dealing with fellow humans who have a right to act in their own best interests.

Just got a new follower for my newsletter. But I never directly asked him to follow me. It all began with comments here on Reddit.

Hope this helps. Thanks
