The one you get asked about. Or the one you are least sure of. Send the name, nothing else.
01
What happens
Would rather just email? Write to melissa.ms@melimethods.com with the compound name.
02
If you would rather talk
Bring the ingredient to the call instead.
Same rules. One compound name, and no obligation at the end of it.
03
If the story is already written
Send the story and the evidence behind it instead.
Some companies already have the story. What they want is someone to check it before it goes out, and then say it on camera. That is its own thing, and it is priced on the home page as your story, checked, and a video. If the evidence does not hold, you are told what did not hold and why, at no charge, and no video gets made.
04
Before you write
You already know which ingredient it would be.
It is the one that comes up on every call, or the one your customers keep asking about. Either is the right place to start.
