Email send from content builder send flow

Question

I'm trying to send an email using content builder send flow, at the time of selecting the audience, i'm selecting Salesforce campaign and clicking on next to check the checkbox "this information is correct and ready to send" and when the send button is enabled, i clicked on send but after sometime i get a error message saying

There was an error sending this Email

Email doesn't contain any ampscript code.

Any idea what cloud be the issue with the send?

Answer 1

i went to admin settings and checked if the user is integrated with salesforce or not, and i was that my user name was not integrated. I clicked on integrate and then refreshed the page. Went back and followed the same procedure to send an email using content builder send flow and selected salesforce campaign and email was sent.
