If everyone can basically tell when you use AI generated graphics, they can with your captions and copy.
Again, while it might feel like it saves time and money, AI captions can come across as wordy, over-complicated...you are better off spending your time creating your own voice, your own style. People will notice the difference.
With any major promotion or campaign, along with the usual channels, I like to have one experiment running. It might be a different type of content, an A/B EDM (where different audiences have different email campaigns), different audience types in your paid Meta adverts, or connecting with a different content creator to tap into their audience.
Add one element of experimentation might open a new path or new way to promote your brand.
