Luma Mail uses Amazon SES as their primary email service provider. Email goes out from 3 different subdomains. Their email authentication setup is solid (score 85/100).
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 luma.com. Policy
p=reject means receivers actively block or quarantine spoofed mail.
SPF alignment: 99% of observed emails use an aligned return-path (amazonses.user.luma-mail.com, amazonses.calendar.luma-mail.com, amazonses.luma-mail.com); the rest use third-party paths (customer.io) where DMARC has to rely on DKIM alignment.
DKIM alignment: all 167 observed emails sign with a domain aligned with luma-mail.com (user.luma-mail.com, calendar.luma-mail.com, luma-mail.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: modern — 100% TLS 1.3 (across 73 sends).
Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 31 sends).
Gmail's own filter showed these warnings to real subscribers in their inbox — independent of SPF/DKIM/DMARC pass/fail status. A consistent pattern often signals reputation issues or brand-impersonation concerns.
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.

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 | 191 | 94.1% |
| promotions | 12 | 5.9% |
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 % |
|---|---|---|---|---|---|
| Amazon SES | 178 | 93.3% | 6.7% | 0.0% |
Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
