Lenovo uses Bluecore for marketing email and SendGrid for transactional/notifications. They rank #819 in the Tranco list of most-popular domains. We've also observed sends via Amazon SES. Email goes out from 2 different subdomains. 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 dmarcian. Policy
p=reject means receivers actively block or quarantine spoofed mail.
SPF alignment: 86% of observed emails use an aligned return-path (em.ecomm.lenovo.com); the rest use third-party paths (amazonses.com) where DMARC has to rely on DKIM alignment.
DKIM alignment: all 4 observed emails sign with a domain aligned with lenovo.com (ecomm.lenovo.com, idmail.lenovo.com). DKIM authenticates the visible From — supports DMARC directly.
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
Amazon SES 1ESPs 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.

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 % |
|---|---|---|---|---|---|
| Bluecore | 6 | 16.7% | 83.3% | 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.
