Thank you for reaching out to the community!
I am sorry to hear that you are having trouble with your welcome email. I have taken a look at your account and it appears that you have 2 welcome emails. One of which has edited content and the other is inactive with the default content. We would like to take a closer look and discuss this matter in a private email conversation as to keep your information safe. Would you kindly send an email to social_support(at)constantcontact(dot)com with a reference to this post and the name of the campaign that you are referring to?
We hope to hear from you soon!
