-All personalization strings are case-insensitive.
-Include the two sets of double percent symbols (two percent symbols on both sides of the personalization string).
-If you're inserting a personalization string into a line with other data, include a space before and after the personalization string.
-If you insert a personalization string, and the subscriber attribute isn't populated, the string will appear blank in the email. --Define a default value for every attribute you intend to use with a personalization string. For example, use this string to include default attributes for First_Name: %%[IF Empty(First_Name) == "False" THEN SET @FN = First_Name ELSE SET @FN = "Customer" ENDIF]%%Hi %%=v(@FN)=%%
