In very short, here's the most common way to go about prospecting:
Scrape potential clients/opportunities from Linkedin with DuxSoup into a .csv file.
Obtain the contact email addresses of these potential clients straight from DuxSoup, or alternatively from Voila Norbert, Findthatlead, etc.
Send them emails via Salesflare's email workflows feature.
As soon as you receive a reply, create a new Account in Salesflare. This can be done quickly from the Salesflare sidebar when opening in Gmail or Outlook.
Create an opportunity and follow it up through the pipeline. Suggested tasks can be helpful for this.
Close them... and celebrate with a glass of champagne (...or coffee).
