Hi, 

I am trying to create a mass mail adding the HTML signature of each sales person individually.

Unfortunately the HTML is never parsed properly but its always showing HTML code on the received email.

This is the result:

https://drive.google.com/file/d/10i7NMd_MTWCbMcPOA8bI_DGHqzrqd55A/view?usp=sharing

Expected result similar like this (parsed HTML):

https://drive.google.com/file/d/10kucHN3xvaM7QhZniRMotEcL55kSrWEg/view?usp=sharing

I have tried this:

${(object.partner_id.user_id.signature)}

https://drive.google.com/file/d/10kAp6cyu8erJlJCgbA2FKupmiXzrtsIn/view?usp=sharing

Also I tried this but always the same result:

${(object.partner_id.user_id.signature|safe)}
${(object.partner_id.user_id.signature|e)}

I hope you can help me! Thanks a lot!
