M3aawg uses Mailgun as their primary email service provider. They rank #612,252 in the Tranco list of most-popular domains. Email goes out from 3 different subdomains. Their email authentication setup is good (score 72/100).
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 vali.email. Policy
p=quarantine means receivers actively block or quarantine spoofed mail.
SPF alignment: all 19 observed emails use a return-path aligned with m3aawg.org (mailserver.m3aawg.org, test.m3aawg.org). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: all 28 observed emails sign with a domain aligned with m3aawg.org (mailserver.m3aawg.org, lists.m3aawg.org, test.m3aawg.org). DKIM authenticates the visible From — supports DMARC directly.
TLS: 0% TLS 1.3, 100% TLS 1.2 (across 20 sends).
5 of 20 emails in the last 7 days were delayed beyond 5 minutes (25%) — delays stayed within 5–15 minutes. Slow sends averaged 9 min 32 sec, peaked at 14 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).
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 | 14 | 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 % |
|---|---|---|---|---|---|
| Mailgun | 14 | 100.0% | 0.0% | 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.
