Thisthingofours uses Klaviyo as their primary email service provider. They rank #957,542 in the Tranco list of most-popular domains. Their email authentication setup is good (score 73/100). Missing: DMARC enforcement.
Authentication signals observed in this brand's emails. SPF, DKIM and DMARC are the standard sender-authentication stack — see the DMARC policy below for whether spoofing is actually blocked or just monitored. One-click unsubscribe meets Google & Yahoo's bulk-sender requirements.
DMARC published as p=none with no rua= reporting — monitor-only, and the sender isn't collecting reports either.
SPF alignment: all 1 observed email use a return-path aligned with thisthingofours.co.uk (k3.mail.thisthingofours.co.uk). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: all 1 observed email sign with a domain aligned with thisthingofours.co.uk (mail.thisthingofours.co.uk). DKIM authenticates the visible From — supports DMARC directly.
