You can reach your targetted audience by making phone calls, sending emails, targetting on LinkedIn, Twitter, and other social media platforms.
Out of all these options, emails are known to be best suited for generating leads.
Emails provide an opportunity for a potential lead to think before they respond. While making calls, there is more of a pressure to respond in the moment, which might pressure your caller to respond without being convinced.
While if you are getting responses to your emails, then people are responding after getting convinced.
So, the chances of having quality meetings are better in the latter case, in turn, have higher chances of ending up in closed deals.
