Hey @TheCarpoolKing,
Welcome to Klaviyo!
This sort of behavior isn’t uncommon, especially if you’re recently migrated platforms. Chances are you’re sending domain was previously authenticated when you were on Sendgrid, also known as using a dedicated sending domain.
Since moving platforms, you’ll want to realign your domain by using a dedicated sending domain on Klaviyo as well and warm the new domain.
Similarly, you’ll want to ensure your DKIM records are realigned too as that could be another cause for emails being indicated as potential spam.
I hope this helps!

Great response @David To - domain alignment is an important aspect in the world of deliverability. Make sure your SPF, DKIM and DMARC are properly signed and aligned with the sending domain.
As a hygiene practice, also make sure migrating the blacklisted data from Sendgrid (historical bounce records, unsubs, blocks, unsubs, spam complaints, etc.) and suppress on Klaviyo. And, with regards to building reputation, target only most recent engaged subscribers with your best performing content to establish a strong sender reputation.

Mohsin
