currently you can only use the category title as a variable in the subject line.
I’d like to have the option of using {topic_title} in the subject line like you can do with most of the other system emails related to topics.
Benefits of using just category (current state): Email systems will thread emails with the same subject (“New post in {category_title}”). Many communities may prefer this to cut down of email volume.
Benefits of using {topic_title}:
- I’m more likely to click into an email for a subject that interests me / fits my expertise
- I’m less likely to bulk delete X messages rolled up into a group thread in gmail
I think there are good reasons for each approach, I’d like to have the option for either.
