Notes on Capabilities
DMARC: Arlo runs on SendGrid and supports full DMARC compliance.
DKIM: Contact Arlo for DKIM setup.
SPF: There is an include ('include:_spf.arlo.co'), but it uses 2 DNS lookups. Instead, try adding the individual IPs to your SPF ('ip4:184.108.40.206', 'ip4:220.127.116.11', 'ip4:18.104.22.168', 'ip4:22.214.171.124', 'ip4:126.96.36.199', 'ip4:188.8.131.52') and be sure to double check with Arlo if something has changed on their end.
When deploying DMARC, domain owners often find new sources of email.
Domain owners then wonder if the source is capable of sending DMARC compliant email.
