I apologize for any confusion this sending delay may cause! We have put a 10 minute sending delay in place as a proactive measure to ensure you are getting the best deliverability rates possible. This is done to help establish your sending reputation with Constant Contact. However users with more than 10,000 contacts may experience a delay longer than 10 minutes. The earliest time the campaign will start sending is shown on the page displayed after scheduling.
Since enabling this feature, it has caused many issues for my organization as we have used constant contact to send URGENT messages including system outages. This feature should be able to be turned on/off at the account owners discretion. Unfortunately changes CC is making is causing us to have to evaluate other communication tools for a better fit. (it says "new member" because I just have just started a new account with a new team as our organization has been a CC user for many years)
