Why do some recipients see placeholder text (e.g., "Header 01", "Button Text") in their emails while others see the correct content?

This issue typically occurs due to incomplete Localization settings in the email configuration.

The Cause

This happens when the Default template is fully configured with the correct content, but a specific Language variant (e.g., Spanish, French) has been added to the configuration and left with default placeholder elements.

• Users falling under the Default locale receive the correct content.
• Users matching the specific Language profile receive the incomplete template containing placeholders like "Header 01" or non-functional buttons.

How to Fix

To resolve this for future sends, open your Email Content editor and choose one of the following options:

1. Remove the extra localization: If your Default template is already written in the desired language, remove the specific language tab (unselect it in the "Choose language" menu). This ensures all users receive the Default content.
2. Complete the localization: Copy the content from the Default tab into the specific language tab to ensure it is fully populated.

How to Fix for Affected Users (Resend)

Emails that have already been delivered cannot be updated remotely. To fix the issue for users who received the placeholders, you must resend the campaign. To avoid resending to the entire audience, follow these steps:

1. Create a new Segment.
2. Use the exact criteria from your original audience.
3. Add an additional condition (AND): Language equals [The specific language code that was incomplete] (e.g., es or Spanish).
4. Send the corrected email to this new segment. This targets only the users who originally received the broken version.
