Simple IF ELSE Statement in AMPScript.

If else statements are the basic when writing logic in any programming language.

You can define an outcome when a condition is true or false.

Below is a simple example of an IF Else Statement using AMPScript to define the subject line for an email based on gender.

In our scenario, we have two gender values, M and F.

Simple IF ELSE Statement in AMPScript

The code snippet below defines two variables which will be used to store information. (@gender and @subjectline).

When the gender from the table equals “M“, the text “The boys have arrived.” will be stored in the @subjectline variable.

If the above case is false, the text “The girls are here.” is stored in the @subjectline variable.

Finally, there is an output function that writes the output value of the variable @subjectline

AMPScript Code

%%[
var @gender, @subjectline
set @gender = gender_flag /* field in DE */

if @gender == "M" then
    set @subjectline = “The boys have arrived.”
else
    set @subjectline = “The girls are here.”

output(v(@subjectline))

endif
]%%

Results

Gender_Flag	Output
M	The boys have arrived.
F	The girls are here.

You can use multiple If else conditions in your code if required by using the “elseif” function.

AMPScript Code

if @gender == "M" then
    set @subjectline = “The boys have arrived.”

    set @subjectline = “The boys have here.”

else
    set @subjectline = “The girls are here.”

output(v(@subjectline))

endif
]%%
