What social media information are you wanting to automatically pull?
In terms of automation, if you are trying to find a contacts social media accounts based on their email, this will be difficult, as most social media services don't have this publically listed.
But if you provide a link to their social media accounts, what information do you want exactly? Followers, Likes, Status Updates, Posts, and what is your reasoning for this?
I simply wanted to pull their social media profile links. Other CRM programs do this, basing it, I guess, on a combination of their name and organization. (Some give you a couple of options and you can choose which is the right profile.)
What are the names of the other CRM's that you are refering too?
