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 gmail.com. Policy
p=none is monitor-only — receivers won't act on spoofing yet.
SPF alignment: 79% of observed emails use an aligned return-path (cioeu110647.really.reallygoodemails.com); the rest use third-party paths (flowium.com, emailmarketingnyc.com) where DMARC has to rely on DKIM alignment.
DKIM alignment: all 100 observed emails sign with a domain aligned with reallygoodemails.com (really.reallygoodemails.com, cioeu110647.really.reallygoodemails.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: 79% TLS 1.3, 21% TLS 1.2 (across 70 sends).
7 of 33 emails in the last 7 days were delayed beyond 5 minutes (21%) — peaks past 15 minutes are well outside healthy sender behaviour. Slow sends averaged 19 min, peaked at 26 min. Healthy senders deliver in under 30 seconds. Consistent delays usually mean greylisting, reputation-based throttling, or receiver-side filter scrutiny — worth investigating sender reputation and authentication setup.
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
Customer.io 17 Zendesk 3 Mailgun 1ESPs 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.

Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.

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