Bulk email

How do I opt out of the Beta Contacts format? I switched to Classic Email, but that did not affect Contacts.?
BUT…I cannnot access my contacts. The first 20 or so load, and then the whirlygigs start whirling and if I let them, they will sit and whirl for 10 plus minutes without loading the next group of contacts. THIS CANNOT BE CONSIDERED WORKING!

And the emails seem to be frozen in outlook email inbox
