What your Scorecard measures

Nine signals, weighted toward what actually moves inbox placement.

Authentication carries the most weight, because it's what ISPs check first. Every signal is graded on the evidence we can see, and labeled when an outside-in scan can only infer it.

Authentication · heaviest weight

  • DMARC policy & reporting (none → quarantine → reject)
  • SPF presence & Klaviyo alignment
  • DKIM signing & key strength

Brand & reputation

  • BIMI record + VMC verification
  • Blacklist presence (Spamhaus, SURBL, Barracuda)
  • PTR / reverse-DNS match

Infrastructure & hygiene

  • Dedicated sending subdomain
  • Custom tracking domain
  • Inbound MX TLS support

How we grade

A · 90–100
Top 5%. Deliverability isn't holding you back.
B · 75–89
Top quartile. Known fixes close the gap to A.
C · 60–74
Around category median. Real revenue on the table.
D · 45–59
Below median. Leaking revenue every send.
F · 0–44
Crisis. Every send reinforces the reputation problem.
