Prevent Blank Fields: Set Default Fallback Values for Custom Values!
Go HighLevel now allows you to set default fallback values for custom fields, ensuring your emails never show blank spaces when contact data is missing.

What changed
Go HighLevel has introduced the ability to set default fallback values for custom values used in emails. This feature applies to both the email builder and manual syntax, and extends to subject lines and preview text.
Why it matters
This update is crucial for maintaining professional communication. Missing contact data, such as a first name, previously resulted in awkward blank spaces in emails. Fallback values ensure your messages always look complete and personalized, even when specific contact information isn't available.
How to use it
You can configure fallbacks directly within the email builder when inserting a custom value, or manually add the fallback syntax to your custom value (e.g., {{contact.first_name|"Valued Customer"}}). Each custom value can have one default fallback. This helps your marketing look more polished and improves the reader experience.
