I just sent 3 campaigns with the same names as I made slight tweaks to each.
It's be great to include notes sending campaigns to help us differentiate each one. I know we can preview the emails but having a small text field within each would be really helpful.
Welcome to the Forums, eladnova! I can see how that would be beneficial so, I've recorded your vote for notes on sent campaigns. We count all votes and consider them when planning out which new features we will work on, so every vote helps.
In the meantime, if you want us to change the name of those 3 campaigns in order to distinguish them a bit contact us with details and we'd be happy to update them for you. There is a 250 character limit, but that should allow you enough space to identify them.
We'll be in touch if we add in campaign notes in the future. Thanks for letting us know what you'd like to see!
