I’ve looked at pretty much everything that exists out there for LinkedIn. MP could do it but not at the pace they are moving, at this speed the gap keeps increasing. MP fills in a gap that other tools have at the moment, so there’s a use for it alongside the other tools. I remain hopeful though as I also like using MP and am familiar with it and the community.
There is progress being made in MP on core functionality, Ciras mentioned all the great progress so far, but what the future holds in this field is email-marketing like automation (if/then workflows, good campaign management functionality), smart inboxes that help manage leads and deals (how does sentiment analysis sound?), and integration with Webhooks and Zapier - this last one is a must as it allows you to access a whole world of additional functionality. Have not seen any indication that MP will add such functionality but if they do add it, faster than the competition manages to pull ahead, then they have a fighting chance.
Where MP can win out as things stand is to be the most cost-effective and manager-friendly for managing large amounts of accounts at the best price, offering the main functions of connection + follow up messages and some extras without the advanced stuff I mentioned in the previous paragraph. The main drawback to other LI solutions is the use of browser profiles or the expense that comes with cloud hosted services. So MP is definitely still in the game, but it’s not the be-all and end-all tool for LI.
BTW I had a feature request thread for LinkedIn features with a ton of stuff that was being worked on and the the thread seems to have disappeared from the forum. Does anyone know what happened to it?
