Centrodeopinion uses Amazon SES as their primary email service provider. They're the #763,444 most-visited website overall, per Tranco (a web-popularity measure, not an email one). Their email authentication setup is good (score 73/100). Missing: DMARC enforcement.
Amazon SESAuthentication 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 8 emails we've observed. DMARC policy is read live from DNS.
DMARC reports sent to everest.email. Policy
p=none is monitor-only — receivers won't act on spoofing yet.
SPF alignment: all 8 observed emails use a return-path aligned with centrodeopinion.es (mail.centrodeopinion.es). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: all 8 observed emails sign with a domain aligned with centrodeopinion.es (centrodeopinion.es). DKIM authenticates the visible From — supports DMARC directly.
Delivery: fast — 88% of emails in the last 7 days arrive in under 10 seconds (across 8 sends).

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.
