Heliumdeploy uses Klaviyo as their primary email service provider. Their email authentication setup is incomplete (score 53/100). Missing: DMARC, 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 1 email we've observed. DMARC policy is read live from DNS.
DMARC reports sent to heliumdeploy.io. Policy
p=none is monitor-only — receivers won't act on spoofing yet.
SPF alignment: all 1 observed email use a return-path aligned with heliumdeploy.com (k3.send.heliumdeploy.com). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: all 1 observed email sign with a domain aligned with heliumdeploy.com (send.heliumdeploy.com). DKIM authenticates the visible From — supports DMARC directly.
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.

Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
