The list is the recipients, the accounts are the workers. How the list divides between them affects both the result and how long the accounts last.
The main rule: no overlap
One recipient, one account. Give two accounts the same list and some people get two similar messages from two different strangers. That looks worse than two from one: the system becomes obvious.
How to divide
- Evenly by account count, adjusted for age: less for fresh ones — daily volume.
- By segment, if the list is split by topic: then each account owns an audience and a phrasing.
- Not alphabetically. Sorting by name often groups people by country or language, and one account gets the whole segment.
When an account drops out
If one picks up a restriction, its share should not move to another the same day. Otherwise that account takes double load and follows it. Better to pause that part and return to it later.
Records
A log of «who was messaged from which account» is needed not only against repeats but for diagnosis: if complaints cluster on one account, the cause is usually its segment rather than the account — on logs.
How Neurogram does this
Everything above is manual work that runs into the number of hours in a day. Neurogram does it on your own accounts and without you: it collects channels and audiences, writes comments and replies with a language model, and keeps limits and quiet hours so the accounts survive.
