Traditional mail merge emails your whole list. Conditional sending emails only the rows that deserve an email today — here is why that changes everything.
Classic mail merge has one setting: send to everyone in the list. That works for a newsletter and fails for almost every operational email a business actually sends.
Describe a state, not a list
Conditional sending flips the model. Instead of preparing a list, you describe the state that deserves an email:
Payment = PendingStatus = ApprovedScore > 80
Mailvern reads your sheet, finds the rows in that state and emails only those.
Your spreadsheet becomes the campaign
The practical effect is that your spreadsheet becomes the campaign. You stop maintaining a second copy of the truth in an email tool, and you stop worrying about who got what.
