Sharkninja uses Bloomreach for marketing email and Mailgun for transactional/notifications. They rank #21,992 in the Tranco list of most-popular domains. Email goes out from 3 different subdomains. 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.
SPF / DKIM / DMARC above reflect the last 4 emails we've observed. DMARC policy is read live from DNS.
DMARC reports sent to cloudflare.net. Policy
p=none is monitor-only — receivers won't act on spoofing yet.
DKIM alignment: all 26 observed emails sign with a domain aligned with sharkninja.com (fr.email.sharkninja.com, pl.email.sharkninja.com, es.email.sharkninja.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: 0% TLS 1.3, 100% TLS 1.2 (across 13 sends).
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
None — only the primary ESP(s) shown aboveESPs 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.
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.

Which ESP's emails are landing where. Sorted by spam % so problem senders surface first.

Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.
