Instead of using the same message template for everyone, MailMoo allows you to dynamically insert entire custom messages per lead, including multi-line text at scale.
This is ideal when every prospect needs a slightly (or completely) different message or don't want to use one word variables for perosnalising messages.
The Key Concept: One Message Per Lead
MailMoo doesn’t limit personalization to single words like first name or company.
You can:
Write a complete custom message per lead
Store that message in your CSV or spreadsheet
Send it automatically using a single variable
This works because MailMoo fully supports newline characters and long text inside variables.
Prepare Your Lead Sheet
In your CSV or Google Sheet:
Create a column called something like
MessageWrite a fully personalized LinkedIn message for each lead
