**Your software** My Mautic version is:3.3 My PHP version is: 7.4.22 **Your problem** My problem is: i have a site which has 50 courses which we have set up as custom fields. Our use case is that when a user enrolls in a specific course we want to start a drip to motivate him to complete a course. In the email we want to say Hi XYZ, Welcome to ABC Course on LearnVern where the abc course name would be 1 of 50 that he has enrolled for How do I call out the course name without changing the email template with hard coded course name for each course. I am able to use custom first name. But as each user might have multiple courses for which they have enrolled. How do I send a welcome email with Fname and Custom Field Course Name. Thanks in advance ---

Hi, the course name is random from the list? > abc course name would be 1 of 50 that he has enrolled for Can you save a custom field in Json where you save all active courses? This would make your life a lot easier and enable automation. Format: ```auto {% set courses = formresult.json | json_decode %} {% for course in courses %} {{course.name}} {% endfor %} (edited) ``` If yes, you can use the Twig plugin to show randomised content. Format: `{{ random(['apple', 'orange', 'citrus']) }}` ---

Hi Joey, i have a short question about saving json data in a contact: How can I define a custom field to save json? Is it just a custom field with type “text”? Because when I try to save data in this field (via ui/form) I got the validation error that max 191 chars can be saved. But 191 is to less for our json data. Is there a way to save longer text (or explicit json) to a custom field? Best regards, Timo ---

Hi, you can use Text area field type, that is longer: ![image](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/6/6ea1da61ad3ed37d94dba79489e5ebbcf7a05de8.png) ---

Hi Joey, thanks for your quick reply! Sorry I didn’t see the “allow html” switch in custom field configuration. Is this a new feature in mautic? We currently use version 4.3.1. Best regards, Timo ---

Hi Joey, I have one more question about this: Do you ever handled links in twig templates? It seems that utm tracking parameter from the email are not added to the links inside a twig template. Do you have experiences with this? Best regards, Timo ---
