This auto email itself stated the following points (to summarize):
-Its a 'a new web interface designed to make campaign management faster and easier.'
-'You'll have at least 30 days from the date of this email before you'll be required to use the new interface'
-'We're working to ensure that the new interface contains all of the reports and controls you need to manage your campaigns effectively'
Therefore there are two major points I will summarize with:
1. This is happening to everyone
2. You don't have a choice (so you might as well switch and get used to it asap)
If you have already familiarized yourself with the new platform, please pass along any help or feedback you may have.
