It would be helpful to have this feature, which appears to be available under legacy accounts but not newer ones.
Thank you for reaching out to the community! That's a great question. Though the forward to a friend feature is only available in the legacy editor, you can still use the forward to a friend feature to send your emails to friends whether they use the newer editor or not.
Please let us know if you have any further questions!
What I was hoping to do was have the forward feature lead to a sign up list here on Constant Contact.
ETA, A friend who had it on her Legacy account, said everything has changed, and not for the better. I guess she was forced to upgrade to the newer system.
