Email setup 80/100

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.

Solid setup, room to improve
Most authentication signals are present. A couple of pieces would tighten things up.

SPF lookups 3/10

SPF / DKIM / DMARC above reflect the last 3 emails we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to the5ers.com. Policy p=quarantine means receivers actively block or quarantine spoofed mail.

SPF alignment: observed emails use a third-party return-path (mail140.sea51.mcsv.net, mail235.wdc02.mcdlv.net, mail45.atl31.mcdlv.net) — SPF passes there but doesn't align with the5ers.com, so DMARC has to rely on DKIM alignment.

DKIM alignment: all 7 observed emails sign with a domain aligned with the5ers.com (the5ers.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability
🐌 Significant delivery delays observed

2 of 3 emails in the last 7 days were delayed beyond 5 minutes (67%) — peaks past 15 minutes are well outside healthy sender behaviour. Slow sends averaged 16 min, peaked at 19 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.

Other ESPs detected

Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).

None — only the primary ESP(s) shown above

Confirmed senders

ESPs 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.

Other SPF authorizations

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.

Where emails landed (Gmail)

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

Placement by ESP

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.

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