SEO is a team game, successful SEO campaign should have a great content player to write creative content, an outstanding killer outreach person to build relationship with the targeted audience and perfect social media strategist to deal with the social challenges.
The job of an outreach person is very important because if he is a lose end in the team, all the efforts of the team can go waste. An ideal outreach person should know how to craft an email to get a better rate of response.
I have been a consultant for multiple teams in the past two years and worked with different people. As far as outreaching is concerned, there was a very unique problem I witnessed and that was low response rate of some campaigns even after the email was perfectly written.
