email URL forwarding with office365/AWS

I have 2 domains names that I have acquired through namecheap. ABC.com and ILOVEMYABCS.com

I am using @ABC.com for my emails but I want ABC.com(the webpage) to forward to ILOVEMYABCS.com just in case anyone ever types it in the web browser.

any suggestions on how to do this? I have office365 and currently setting up amazon web services.
