Hi there @3000month2021,
Thanks for posting to the Community with your question! Hope I can advise on what you are trying to accomplish.
Are you looking to find a way to use an email template multiple times for various flows? If this is the case then I would recommend saving an email template!
Saving email templates is an easy way to cut down time building your campaigns or flow emails. Saved templates can be used as a starting point for future emails. From the Email Templates tab, you can build out a template directly or edit saved email templates.
I am unsure what you mean by copy and pasting emails from flow 1 to 2 but i think that means creating an email template of emails used in flow 1 to be used in flow 2?
In the meantime, I also recommend checking out our academy guide on getting started with email design! It provides a general overveiew of making emails and I find it very resourceful!
Let me know if that helped!
