The solution in Odoo 15 is to switch to code view first (enable debug mode, then click the code view option in the top-right of the email template editor).

Adapt and place the following Qweb style tag where you need it:

<t t-out="object.name"></t>

Hi István,

I found this video and after checking a bunch of forums it seems that the dynamic values don't work in Odoo 15. The email marketing is frankly not at all up to par with other softwares in the market and is not very user-friendly at all. 

Here is a video that you might find useful. The only way to make it work apparently is to edit the email templates directly:https://www.youtube.com/watch?v=VQJodqSE5DM

Until we decide to do some more customisation work and fix the interface, we have decided to look at alternative softwares for email marketing. 

Best of luck!

I tried some variables, all of them are failed. Did you figure out since august, how to do it?

I tried these, all of them are failed:

${object.display_name}
{{ object.display_name }}
{{ object.partner_id.id }}
${object.name}
{{ object.name }}

Thanks, István
