All carefully curated!

There are also other unmentioned ongoing administrative and curative costs.

Because remember...you are sending these out to a list you or someone else has curated. 

For us, we came from a marketing, branding, investor relations background and developed a Marketing Plan and Investor Relations Guidebook that we curated for individuals with $100m+ in assets.
