Reach beyond your direct contacts

Is any of you involved in creating awareness/enablement campaigns for end users that you are not in direct contact with? The challenge is to get your contacts to reshare the posts you send them.

I am involved in such situation and having quite a challenge with these gatekeepers.

Aside from
- promoting the adoption value of these campaigns
- not calling them "campaigns" so they do not get confused with marketing tactics
- making them conveniently available to follow their deployment schedule
- offering the capability to understand the reach and the impact on usage

I am thinking about
- offering.gifts certification when we can see total shares in hundreds or thousands
- providing access more often to goodies like infographics, videos, etc.

What has been your experience? Any good tip or word of advice?
