Namecheap uses Iterable for marketing email and SendGrid for transactional/notifications. They rank #3,017 in the Tranco list of most-popular domains. Their email authentication setup is solid (score 100/100).
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 8 emails we've observed. DMARC policy is read live from DNS.
DMARC reports sent to DMARC Analyzer (Mimecast). Policy
p=reject means receivers actively block or quarantine spoofed mail.
SPF alignment: 91% of observed emails use an aligned return-path (mailserviceemailout1.namecheap.com); the rest use third-party paths (experte.com) where DMARC has to rely on DKIM alignment.
DKIM alignment: all 28 observed emails sign with a domain aligned with namecheap.com (namecheap.com). DKIM authenticates the visible From — supports DMARC directly.
VMC issued by: digicert.
TLS: modern — 100% TLS 1.3 (across 12 sends).
Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 6 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.
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 |

| promotions | 1 | 2.3% |
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 | 5 | 100.0% | 0.0% | 0.0% | |
| SendGrid | 32 | 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.
