It's extremely short and probably impossible, even with no hold luggage. Easyjet has no interline agreement with other airlines, which means not only that they would not take care of any hold luggage for you but also that they don't offer any facilities for transfer whatsoever and that the answers to earlier questions about transfer in Amsterdam do not apply. They will simply treat you as if you came from outside the airport and expect you to be there well in advance for security and boarding formalities.
Easyjet flights depart from the low-cost pier, which is a bit off the way, has long corridors and frequently long lines for security. Delta flights mostly dock at D-gates, in departure hall 2, so you will have to walk to departure hall 3 and then some more to the low-cost pier (but contrary to what I wrote in an earlier version of my answer, you should be able to do that airside and avoid waiting for a passport check).
Because Easyjet only operates point-to-point flights, they also won't help you in any way if you miss your plane. If you have any delay and fail to show up at the gate in time, you will be treated as a no-show and simply forgo the benefit of your ticket. At most, they might allow you to change to a later flight (I had to do this one time that security was particularly bad, and the fee was €50).
On the other hand, boarding passes can be printed 30 days in advance (the default is automatic online check-in, not airport check-in, I am not sure whether the latter is still possible at all) so at least you don't need to worry about that. Otherwise, you would need to queue again at Easyjet departure desks, with all the passengers starting in Amsterdam (no transfer desk either). Because I always check-in online, I don't know how long this typically takes but I have seen long lines there as well.
