Why someone will buy from you? When you will directly reach to customers through DM's why they will reply you? They don't reply because you didn't build relationship instead starting sending sales DMs
But before building realationship build initial ICS (Ideal Client Avatar).
if you will not deeply know about your target market like what problems they are facing in their businesses, what CRMS they use, on which social platform they are active etc.
Now question is that how will you get to know that what problems or challenges they are facing and without not knowing their problems how will you find their solutions and how will you convert them into long term clients. you will only get insights when you will build relationship with them . Without relationship they will treat you like a sales reps. By building relationship They will tell you about their problems that they never gonna tell to a cold caller
Now with time to time refine ICA and refine your outreach strategies
