Changing sender email domain, but not CNAME/Branding Domain

Hi,

Anyone know if there are implications to sender reputation or deliverability if you change your sender email domain but don't immediately update your CNAME and branding domain?

 

Example

CNAME = myoldcompany.com

Branding Domain = info.myoldcompany.com

Sender/reply-to email domain = @mynewcompany.com

 

Note, we do not have SPF/DKIM setup...yet.

 

Thanks,

Sean
