Anyone got ideas on a WP plugin or some code that will insert a pre-designed opt-in box/graphic at certain points in all posts? Or even at random. 🤔

I have over 3000 posts now. While back I designed graphics that open as a popup for getting on my list (then selling my courses)

However, I didn’t think it through and now have to change multiple opt-ins in over 3000 posts! 😮

Be great to have something that I can set in a dashboard and then change whenever I want (graphics, links) etc. change at central source and that changes all the opt-ins across site.

It’s weird that no major opt-in/popup plug-in offers this functionality. Will most likely have to custom code?
