I do greatly appreciate that you made it possible to write a custom subject line for our videos 🙌🙌 However; sales agents are lazy and don't bother so we still end up with 100's of "RE: I just recorded a video for you" videos being send.
What would be more beneficial would be to remove that default subject line entirely and force the sales agent to input their own. Make the subject and the message section required fields before sending.
I believe this would help increase engagement.
