Asking for referrals from end-users
Thought Leader 
For our high-touch customers we onboard and manage our end-users in a tech-touch way.
Does the community have any best-practices or email templates to ask the end-users to increase the impact on themselves and the company (and basically ask for more money).
Either ask for a referral to a friend/colleague, or ask them if they want to expand their opportunities within the product?
