Currently there is no ability to upload a custom email template for a daily log.
For every other module where you have the ability to email from, you can do a custom email template to match your company's desired font, signature, logo etc but with no ability to upload a custom one, you are stuck with using the SageCM default one.
These daily logs do get emailed out externally so not being able to have them appear like your other emails isn't a great look.

Thank you for pointing this out. I am surprised we missed this before. I sent in a request to add a new help topic. I sent in a request to add the Reports & Templates > Email Templates > Daily Logs to the features available to upload.
I suspect this was just an oversight. I attached a few screen shots to document our research.
