Compare Kilo with another brand:

Email setup 65/100

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.

Solid setup, room to improve

Most authentication signals are present. A couple of pieces would tighten things up.

Authentication

SPF alignment: observed emails use a third-party return-path (pm.mtasv.net) — SPF passes there but doesn't align with kilo.live, so DMARC has to rely on DKIM alignment.

Other ESPs detected

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

None — only the primary ESP(s) shown above

Confirmed senders

ESPs we've seen sending email for this brand. Green = confirmed by SPF, sender IP rDNS, or known infra pairing (label shows the source). Grey = observed but not yet confirmed by SPF or PTR.

SPF authorizations

No SPF record published on the apex kilo.live. Emails from this brand still pass SPF — most ESPs handle SPF on a sending subdomain (Return-Path) rather than the apex. Adding an apex SPF (even v=spf1 -all) would block direct spoofing of unused From: addresses.

Where emails landed (Gmail)

Folder distribution across all emails from this brand observed in Gmail inboxes. High inbox % = good deliverability; spam appearances are the headline signal.
