Hi,
It's a late response, but if you have not received an answer yet my response might still be helpfull.
Adding DKIM records for Qualtrics or any other sender that supports/uses DKIM does not mean you have to add DKIM for everything at the same time. A DKIM record is unique for every sending mailserver! You can have multiple DKIM records for every sender in your domain, as long as the selector is unique. The selector is something like:
s1._domainkey.example.com
s2._domainkey.example.com
qualtrics_1234567._domainkey.example.com
qualtrics_2345678._domainkey.example.com
etc...
So, if you implement DKIM on your own mailserver (which is recommended) you just select a new name for a selector.
More information I found very informative can be found here:
How to Implement DMARC/DKIM/SPF to Stop Email Spoofing/Phishing: The Definitive Guide - DMARCLYI have no relation with dmarcly, I just found their information to be useful.
Good luck!
