The structure is:
[Workbook]
[T1] Account List IN > Different people searches
For each Persona table, looking up the account in salesforce, enriching email, looking up contact/lead objects in salesforce, verifying the email, etc etc > creating recrods>adding to email and ads campaigns + to salesforce campaign.
It all depends on the account list table pulling through correctly in the linked tables.
This is currently holding up a campaign for a client so hope you can help.
