Sending domain says its active then disappears

Question

We have setup a sending domain as “send” and used “dynamic” configuration. Our DNS provider is Amazon which does accept NS records.  The process properly created 3 NS records and one TXT record.  Once complete it said it was active.  But if I navigate away from Settings/Domains and then back, its gone.  But the Klaviyo DNS entries are all still there in our DNS.  I tried sending emails but they get stuck in spam and are using the Klaviyo shared sending domain.  Why is this happening?

Hey ​@AndrewTX,Just to rule out the obvious, the names and valuesrecords in Amazon match the records that Klaviyo provides, correct? If so, we can rule that out as the issue. Whenever I see an issue like this, I like to take a look at 3rd party sites like MXToolboxor DNSchecker.org, and entering the NS and TXT record details in there. That helps determine whether the issue is Klaviyo-specific, or if other parties are failing to recognize the records as well.Additionally, if setting up records using dynamic routing (NS records) doesn’t work, you might see success with static routing (CNAME records). Finally, if you’ve reached a dead end, and CNAME records aren’t being recognized either, I’d recommend reaching out to Amazon, and letting them know that records that are entered onto AWS aren’t propagating as expected. Let me know if I can answer any additional questions regarding this.

As it turned out, what finally fixed the issue was using to a ‘Static’ sending sub-domain setup and manually adding the CNAME records and the TXT record. Important to note that the Klaviyo value in the TXT record MUST go before the SPF/include statement.

Makes no sense why Amazon wouldnt propagate the Dynamic/NS records - they were recognized in several countries like Italy and Mexico, but not at any reporting location in the US.
