What's keeping glancefoundry.com from an A

Mail servers without IPv6
mx01.mail.icloud.com, mx02.mail.icloud.com have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.

glancefoundry.com Has IPv6

A (IPv4)	172.67.139.193 104.21.26.252
AAAA (IPv6)	2606:4700:3037::6815:1afc 2606:4700:3033::ac43:8bc1

Browsers on dual-stack networks will usually pick IPv6 here (the "Happy Eyeballs" algorithm races both and prefers v6).
