Rewardengine uses Amazon SES as their primary email service provider. They're the #856,639 most-visited website overall, per Tranco (a web-popularity measure, not an email one). Their email authentication setup is good (score 70/100). Missing: DMARC enforcement, one-click unsubscribe.
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 4 emails we've observed. DMARC policy is read live from DNS.
No DMARC record published. Domain is not protected against spoofing.
SPF alignment: observed emails use a third-party return-path (eu-west-2.amazonses.com) — SPF passes there but doesn't align with rewardengine.com, so DMARC has to rely on DKIM alignment.
DKIM alignment: all 4 observed emails sign with a domain aligned with rewardengine.com (rewardengine.com). DKIM authenticates the visible From — supports DMARC directly.
Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 4 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.
No additional ESPs authorized in the brand's SPF beyond the confirmed senders above.

Folder distribution across all emails from this brand observed in Gmail inboxes. High inbox % = good deliverability; spam appearances are the headline signal.
| Folder | Count | Share |
|---|---|---|
| inbox | 4 | 100.0% |
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 % |

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