Pmmalliance uses Postmark as their primary email service provider. 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 1 email we've observed. DMARC policy is read live from DNS.
DMARC reports sent to dmarc-report.com. Policy
p=reject means receivers actively block or quarantine spoofed mail.
SPF alignment: all 11 observed emails use a return-path aligned with pmmalliance.com (outbound.intercom.pmmalliance.com, pm-bounces.pmmalliance.com). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: 70% of observed emails sign with an aligned DKIM key (pmmalliance.com); the rest sign with third-party keys (ab.mtasv.net) where DMARC has to rely on SPF alignment.
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
Intercom 8ESPs 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 | 10 | 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 % |
|---|---|---|---|---|---|
| Intercom | 6 | 100.0% | 0.0% | 0.0% | |
| Postmark | 3 | 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.
