Email setup 73/100

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.

Solid setup, room to improve

SPF lookups 4/10

SPF / DKIM / DMARC above reflect the last 3 emails we've observed. DMARC policy is read live from DNS.

Authentication

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

SPF alignment: all 9 observed emails use a return-path aligned with 21-draw.com (mailer.21-draw.com). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 8 observed emails sign with a domain aligned with 21-draw.com (21-draw.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 3 sends).

Other ESPs detected

Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).

None — only the primary ESP(s) shown above

Confirmed senders

ESPs 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.

Brevo ✓ confirmed

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. Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.
