Merge fields not working in Lightning Email Template

Apsona has not yet been updated to fully support Lightning Email Templates. While many customers do use LEX email templates in Apsona without issue, we see occasional issues pop up. If classic email templates are an option, consider using them as you should see more consistently correct behavior from Apsona.

Here are some things to try while using Lightning Email Templates:

• Our documentation ​​​​​​​ describes creating email template merge fields with double curly brackets, rather than triple, which come from Salesforce when you insert them through Salesforce's UI. Try replacing all triple brackets with double to see if performance improves. We've seen Salesforce-style merge fields work in Lightning Templates in Apsona, but this is just something to try based on our documentation.
• Since Apsona doesn't need merge fields to be in the form of API names, try simplifying them to smaller one word labels with no special characters (many special characters get inserted when using the Salesforce-style merge fields). 
• Ensure the same merge field is not referenced in the subject and body of the template. We've seen the tool only merge values into the body when the field is displayed in both place.
• Custom templates with a lot of custom HTML will have more issues in Apsona than simpler templates. Complex HTML is the reason that Apsona is not yet fully compatible with Lightning Templates. Since so much can be customized with custom HTML it's difficult to solve for all use cases that include complex HTML.
