SPF / DKIM / DMARC above reflect the last 7 emails we've observed. DMARC policy is read live from DNS.
DMARC reports sent to dmarc-bloomberg.com. Policy
p=reject means receivers actively block or quarantine spoofed mail.

| Folder | Count | Share |
|---|---|---|
| inbox | 17 | 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 % |
|---|---|---|---|---|---|
| Iterable | 15 | 100.0% | 0.0% | 0.0% | |
| SparkPost | 1 | 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.
