how to customize the send mails personalization for each person, code is below , please anyone

[Kurt_Bremser]

Then I have already given you what to do:

Create a macro which sends one email to one person. It should accept the email address as parameter.

Then read yor initial dataset, and for every observation where day(birthday) = day(today()) and month(birthday) = month(today()) call the macro with CALL EXECUTE.
