Best Practices For Using AMPScript

There are a few best practices that one can follow while using AMPScript.

1. Handle Inaccurate Data

During any campaign, there are always chances of getting bad data that both developers and marketers cannot control. The following steps can be used to handle inaccurate data.

Step 1: Check if a value is empty or null and assign default values for variables

%%[ IF Empty(@Firstname) OR @Firstname == "Unknown" THEN 
set @defaultValue = "Customer" 
set @defaultValue = @Firstname

Step 2: Validate Lookup calls with RowCount and check isEmpty() or isNull() functions.

For example:

IF RowCount(@rows) > 0 then

 /*code here*/

2. Specify Default Content

In dynamic content, specify content in the Default Content field that is shown to a subscriber who doesn’t meet a personalization rule.

3. Cancel A Sent Email

Use the RaiseError function to suppress or cancel an email sent. If an unexpected result occurs, it is also useful for handling exceptions in the code.

if Empty(@couponRow) then
   RaiseError(“No coupons available”, false) 
   SET @Code = Field(@couponRow, “CouponCode”)

4. Set A Specific Date Format

Use FormatDate() to display dates in the preferred format.

For example:

%%=FormatDate(‘2023-09-01 09:00′,’ddddd dd MMMM yyyy’,’HH:MM’,’en-US’)=%%

5. Save A Default Time Format

By default, Salesforce Marketing Cloud uses CST format for dates. To set any other default format, use SystemDateToLocalDate().

For example:

%%=SystemDateToLocalDate(‘2014-11-06 05:00’)=%%

6. Secure Subscriber Information

Use MicrositeURL or CloudPagesURL to secure subscriber information. This function returns the landing page URL appended with an encrypted query string with the subscriber data.

7. Replace Variable Values

Use the Replace() function to replace one variable value with another. This function can be used to replace special characters in the email text.

8. Prevent Validation Errors

Functions like AttributeValue prevent validation errors that terminate emails sent in case of unavailable fields in a data extension.

For example:

%%[ var @myname 
set @myname = AttributeValue('FirstNameColumnName')

9. Unify Different Formats In Databases

Data might be in different formats within different databases. This can be resolved by using the ProperCase() function for properly capitalizing text or a variable.

For example:

Dear %%=propercase(‘john)=%%

10. Ensure Proper Code Maintenance

Debugging AMPScript in the Salesforce Marketing Cloud is not easy due to a lack of built-in features for showing script errors. But there are a few Trailblazer community ideas that developers can explore.

  • Try to wrap your code with Server-side JavaScript try/catch block.

<script runat="server">
%%[ your AMPscript block goes here  ]%%
<script runat="server">

  • Align the code with proper opening and closing script block tags.
  • Align ifelse and endif elements.            
  • Wherever possible, use the variable names that match the send context variable. This helps in ensuring readability in complex scripting scenarios.
  • Add comments wherever required to make the code more understandable.

11. Maintain Code Performance

Salesforce Marketing Cloud follows a multitenant-based architecture. This means that any increase in the database usage can affect all users. Because of this, it is crucial to maintain the performance of the overall code.

  • Reuse the code by writing it in separate blocks.
  • Limit the number of lookup functions to ensure better performance in case of large data extensions.
  • Merge data extensions into one to improve send performance.
  • Avoid overusing functions that impact the send speed like:
    • HTTPGet (Or use cache option)
    • CreateSalesforceObject
    • RetrieveSalesforceObjects
    • UpdateSingleSalesforceObject
    • EncryptSymetric
    • Lookup[Rows]
    • Update/Insert/UpsertDE
    • TreatAsContent


AMPscript unlocks the ability to craft intricate and highly responsive messages that aren't limited by pre-designed templates or user interface guides. By implementing AMPscript, you can enhance the capabilities of Salesforce Marketing Cloud and create personalized communications that appeal to your target audience.
