Email setup 65/100

SPF lookups 10/10

SPF / DKIM / DMARC above reflect the last 5 emails we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to DMARC Analyzer (Mimecast). Policy p=quarantine means receivers actively block or quarantine spoofed mail.

DKIM alignment: all 17 observed emails sign with a domain aligned with quidco.com (info.quidco.com, cashout.quidco.com, hello.quidco.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

TLS: 0% TLS 1.3, 100% TLS 1.2 (across 7 sends).

Other ESPs detected

Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).

Other SPF authorizations

ESPs this brand has authorized in their SPF record. We confirm them with a green ✓ only after seeing recurring use (3+ emails across 2+ days). Until then they stay here — either we haven't observed any email yet, or we've seen a handful but not enough to call them a regular sender for the brand.
