If the existing domain which is configured in Sendgrid and we wish to change the "From Email Address" which can be configured under "Punchh Platform > Whitelabel > Services > Email". If the email address which needs to be updated is from the same domain which is configured already then there will be no impact on email deliverability.
For example: Current "From Email Address" configured was "Abd@punchh.com" and the new one which needs to be updated is "xyz@punchh.com" then there will not impact as new email address also falls in the same domain.
