One of the easiest ways to stay consistent with email marketing is to stop treating it as a separate task.
Create a video.
Use AI to summarize the key points.
Turn that summary into an email.
Now your content feeds your email marketing, and your email marketing drives people back to your content.
If you're already creating videos, you already have the raw material for your emails. At that point, it's not a content problem. It's just a process problem.
