Domain Change - will Emails will still be around if I intend to keep users same?

Hi zoho staff! I have been using a registered domain with Zoho, but i am changing my domain due to rebranding. Will my emails still be around when i delete my previous domain and validate new domain under control panel?

i will be keeping the same users: 
xxx@(new domain).com instead of xxx@(old domain).com.

Hope to hear from you soon.

Thanks!
