We use Sendgrid to send out emails directly from our website. the record is
s1._domainkey.xxx.com s1.domainkey.uxxxxx.wxxx.sendgrid.net.
s2._domainkey.xxx.com sx.domainkey.uxxxxx.wxxx.sendgrid.net.
We also use Klaviyo which also uses sendgrid. They want their records to be...
s1._domainkey.xxx.com s1.domainkey.u161779.wxxx.sendgrid.net
s2._domainkey.xxx.com s2.domainkey.u161779.wxxx.sendgrid.net
How do I add both records? Thank you for looking at this.
UPDATED WITH ANSWER
For the Klaviyo CNAME records
change CNAME send to CNAME send.k (any letter will work)
change CNAME s1._domainkey to s1._domainkey.k
change CNAME s2._domainkey to s2._domainkey.k
There is an unlimited combination of ways you could do the above. This was just the approach that I used.
