Email setup 73/100

SPF / DKIM / DMARC above reflect the last 10 emails we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to zulily.com. Policy p=none is monitor-only — receivers won't act on spoofing yet.

SPF alignment: all 10 observed emails use a return-path aligned with zulily.com (mail.zulily.com, mailer1x9.zulily.com). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 62 observed emails sign with a domain aligned with zulily.com (deals.zulily.com, vip.zulily.com, zulily.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

TLS: 26% TLS 1.3, 74% TLS 1.2 (across 34 sends).

Delivery: fast — 80% of emails in the last 7 days arrive in under 10 seconds (across 10 sends).

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.

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.
