Hi @Martin1232

Thank you for posting in the Community!

Usually a syntax error refers to an error in the content - so in this case I’d recommend you to look at your dynamic variables and personalization for example your {{ first_name|default:'' }} or other variables. If these contain errors - maybe in the subject line or preview text - it will skip due to syntax error.

Let me know if you figure it out!

Hello @annasophiefc

You were right. The issue was that when my customers signed up for the newsletter on Shopify, they weren’t required to enter their names. In the email template, the { first_name|default:'' }} wasn’t required, but in the preview (the one sent to customers), it was required. Now it works, and I hope someone else can learn from my mistake.

Thank you very much for your help!
