| AMPscript a Basic Summary |
AMPScript is processed on the server by the Marketing Cloud system, a document is any Marketing Could HTML/text email, landing page or SMS message.
AMPScript is processed on the server by the Marketing Cloud system. What this means is that by the time a document is sent to the client it has already had any AMPScript rendered. For this discussion a document is any Marketing Could HTML/text email, landing page or SMS message.
AMPScript functions allows documents to:
- use relational data stored in data extensions
- have logic to control rendering
- apply formatting to variables
- How to use AMPScript
For the AMPscript script function block wrap AMPScript function with opening %%[ and closing]%%`` delimiters, for example %%[script]%%`.
For inline AMPscript (or function calls outside or the AMPscript script function block) wrap the AMPScript function with opening %%=and closing=%%`` delimiters, for example %%=function=%%`.
An example of an inline AMPscript function is returning a value, for example %%[ LOWERCASE(Name)]%%.
%%[
var @FirstName
set @FirstName=[field name in data extension or list]
]%%
Open and closing statements: AMPscript always opens and closes with %%[ and]%%, respectively.
- Declaring your variable(s): Next, use “var” to declare the variables you will be calling upon. You can have as many variables as you’d like, but we’ll just keep one for this example.
- Setting your variable(s): Next, you’ll “set” your variable by telling the AMPscript what information to bring in for the variable you declared above.
- If you wanted to pull in the variable you just created above, it would look like the code below. When outputting a variable, we’ll always open and close with %%=and=%%, respectively. Additionally, the “v” indicates the function, and tells the code to output the variable.
%%=v(@FirstName)=%%
If you wanted to use this in a subject line, it could look like this:
%%[var @FirstName set @FirstName=[field name in data extension or list]]%% %%=v(@FirstName)=%%, check out this offer
Now that you understand the basics, here are two ways you can use simple AMPscript to improve and personalize your subject lines.
Propercase function
However, depending on the cleanliness of your data, you may find yourself in situations where some subscribers’ data is uppercase, lowercase, or a combination.
The Propercase AMPscript function can help clean up the presentation of this data. For example, instead of all caps “KELLY” or all lowercase “kelly,” you can easily use the Propercase function to transform the data into “Kelly.”
%%[var @FirstName set @FirstName=[field name in data extension or list]]%%
%%=Propercase(@FirstName)=%%, check out this offer
As you can see from the example above, we replaced the “v” with “Propercase” when calling upon the variable.
Depending on your brand voice and subject line intention, there are also AMPscript formatting functions that can be used to make your text all uppercase or all lowercase.
If Not Empty
Let’s continue with our example of personalizing subject lines using first name, but what if you have subscribers who do not have a first name within your data? In this case, you can utilize the If Not Empty function to provide personalized subject lines for subscribers with first name data and a default subject line without personalization for those who do not.
The Not Empty function provides both personalized subject lines and a default subject line if there is no data.
%%[var @FirstName set @FirstName=[field name in data extension or list]]%%
%%[If Not Empty(@FirstName) Then]%%
%%=Propercase(@FirstName)=%%, check out this offer
%%[Else]%%
Valued Customer, check out this offer
%%[EndIf]%%
While we discussed the examples above in regard to subject lines, the code could be used to personalize other parts of your email, as well.
Below is an example from an email sent by Hallmark. Hallmark used the method above to personalize the body text for subscribers who had first name data, while showing different body text for subscribers without first name data.
Parse First Name from Full with AMPScript
%%[
var @full_name, @first_name
set @full_name=AttributeValue("full_name")
if indexOf(@full_name, " ") > 0 then
set @first_name=substring(@full_name,1,subtract(indexOf(@full_name," "),1))
endif
]%%
Hello, %%=v(@first_name)=%%.
Format date/time via AmpScript
—————————-
Today’s Date Substitution String (Short Date Format):
%%xtshortdate%%
8/14/2011
—————————-
Today’s Date Substitution String (Long Date Format):
%%xtlongdate%%
Sunday, August 14, 2009
—————————-
Today’s Date MM/dd/yyyy:
%%=Format(Now(),"MM/dd/yyyy")=%%
08/14/2011
—————————-
Today’s Date plus 7 days (no formatting):
%%=DateAdd(Now(), "7","D")=%%
8/21/2011 10:05:55 PM
—————————-
Today’s Date plus 7 days (with formatting – no time):
%%=Format(DateAdd(Now(), "7","D"), "MM/dd/yyyy")=%%
8/21/2011 10:05:55 PM
—————————-
Today’s Date plus 7 days (with formatting – no time):
%%=Format(DateAdd(Now(), "7","D"), "MM/dd/yyyy")=%%
08/21/2011
—————————-
FYI – Today’s Date plus 7 days (Format first; Date add second; Time stamp removed; Defaults to midnight)
%%=DateAdd(Format(Now(),"MM/dd/yyyy"), "7","D")=%%
Constants
Constants are fixed numeric, string or boolean values.
Attributes and Data Extensions
Attributes and data extensions are values referenced from functions and objects. Values are enclosed in square brackets, for example [Data Extension Attribute Name].
Keywords
- Keywords are variables declared, initialized, and modified within a script.
- Keywords are prefixed with the @ symbol, for example @Name.
- Keywords are declared using the [VAR] and [SET] syntax, for example:
%%[
VAR @Name
SET @Name="Sam Sample"
]%%
@Name
Conditional logic
Conditional logic is used to control to flow of the script.
Conditional logic consists of:
IF syntax which is used to evaluate a condition, keywords include [IF], [ELSEIF], [ELSE] and [ENDIF].
FOR syntax which is used to process through a loop, keywords include [FOR] and [NEXT].
Output
Output renders code inside a code block, for example %%[Output(Now())]%%.
Comments
Comments are ignored by AMPScript and contain a readable annotations that can help to make code easier to understand, for example %%[ /* Insert Comment Here */]%%.
Functions
Data Modification Functions
There are 2 types of data modification functions. These are used for send time support and landing page support. These functions allow insert, update, upsert (update/insert), and delete actions to be performed at the subscriber level. Data modification functionality include:
Send time support data modification function includes only the InsertDE function.
Landing page support data modification function includes the InsertData, UpdateData, UpsertData and DeleteData functions.Constants
Constants are fixed numeric, string or boolean values.
Attributes and Data Extensions
Attributes and data extensions are values referenced from functions and objects. Values are enclosed in square brackets, for example [Data Extension Attribute Name].

API AMPscript functions
API AMPscript functions allow AMPscript to work with objects in the Marketing Cloud API. The Marketing Cloud API objects allow various functionallity of the Marketing Cloud to be controlled programmaticly. Example use cases include sending emails and creating data extensions.
Refer to API AMPscript functions for complete list of API AMPscript functions. These functions do not work in emails at the time of send. In these function map to method and properties used with objects. In summary functions include:
- AddObjectArrayItem used to add item to array.
- CreateObject used to service API object.
- Field use to return field from object
- InvokeCreate used to invoke the create method on the API object.
- InvokeDelete used to invoke the delete method on the API object.
- InvokeExecute used to invoke the execute method on the API object.
- InvokePerform used to invoke the perform method on the API object.
- InvokeRetrieve used to invoke the retrieve method on the API object.
- InvokeUpdate used to invoke the update method on the API object.
- RaiseError use to handle errors.
- SetObjectProperty used to set a value in the API object.
- Example showing API AMPscript function to insert a record into a data extension.
Following is example showing how to insert a record into a data extension using an API AMPscript function. In example values will be inserted into the nameofEvent and timeofEvent fields of TargetDE data extension. Note that AMPScript also provides InsertData and InsertDE for inserting data into a data extension.
%%[
/* Create data extension object */
Set @de=CreateObject("DataExtensionObject")
SetObjectProperty(@de,"CustomerKey","TargetDE")
/* Create first field to insert into record */
Set @deProperty_1=CreateObject("APIProperty")
SetObjectProperty(@deProperty_1,"Name","nameofEvent")
