Trivago uses Salesforce MC as their primary email service provider. They rank #12,000 in the Tranco list of most-popular domains. Email goes out from 3 different subdomains. Their email authentication setup is good (score 83/100). 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 10 emails we've observed. DMARC policy is read live from DNS.
DMARC reports sent to trivago.com. Policy
p=none is monitor-only — receivers won't act on spoofing yet.
SPF alignment: all 70 observed emails use a return-path aligned with trivago.com (bounce.email.trivago.com, bounce.business.trivago.com, bounce.e.trivago.com). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: 90% of observed emails sign with an aligned DKIM key (email.trivago.com); the rest sign with third-party keys (s6.y.mc.salesforce.com) where DMARC has to rely on SPF alignment.
TLS: modern — 100% TLS 1.3 (across 25 sends).
Delivery: fast — 90% of emails in the last 7 days arrive in under 10 seconds (across 10 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. Brands using one ESP for marketing and another for transactional often see very different placement profiles per ESP. Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.
| ESP | Emails | Placement | Inbox % | Tabs % | Spam % |
|---|---|---|---|---|---|
| Salesforce MC | 61 | 14.8% | 83.6% | 1.6% |
Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
