Your question is very general.

I'd suggest you locate people in Clarify which seem to provide useful advice + book calls with several of them.

How you approach Marketing depends on many factors.

Whether you're an introvert or extrovert, to me, is the most important starting point, because if you're an introvert + try to do extrovert-esque marketing, you'll fail.

Extroverts trying to do introvert-esque marketing will also fail.

Also targeting results, to me, is next on the list.

For example, I'm an introvert, able to masquerade as an extrovert for short periods.

So I bootstrap all my new projects using platform speaking at Meetup groups + conferences.

I target acquiring my first 100+ clients for a project via nose-to-nose selling... well... very soft selling...

Having these core users, I then train them... again, so softly, they never notice... to send me referrals.

100 clients will to pay anything, to me, is worth far more than 1,000,000 of random people on email lists.

I'll take profit over numbers of people, any day.
