Incomeinvestinginsider uses Iterable for marketing email and Amazon SES for transactional/notifications. Their email authentication setup is incomplete (score 50/100). Missing: DMARC enforcement.
Amazon SESAuthentication 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.
Multiple DMARC records published — receivers apply no DMARC at all (RFC 7489). The domain is effectively unprotected until the duplicate record is removed.
SPF alignment: observed emails use a third-party return-path (amazonses.com) — SPF passes there but doesn't align with incomeinvestinginsider.com, so DMARC has to rely on DKIM alignment.
DKIM alignment: all 21 observed emails sign with a domain aligned with incomeinvestinginsider.com (b.incomeinvestinginsider.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: modern — 100% TLS 1.3 (across 15 sends).
Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 14 sends).
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 | 27 | 87.1% |
| promotions | 2 | 6.5% |
| spam | 2 | 6.5% |
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 | 1 | 0.0% | 0.0% | 100.0% | |
| Iterable | 29 | 93.1% | 6.9% | 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.
