Email setup 73/100

Authentication

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

SPF alignment: all 11 observed emails use a return-path aligned with mirlux.nl (noreply.mirlux.nl). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 8 observed emails sign with a domain aligned with mirlux.nl (mirlux.nl). DKIM authenticates the visible From — supports DMARC directly.

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.

Klaviyo ✓ 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.

Where emails landed (Gmail)

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
inbox	13	92.9%
promotions	1	7.1%

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.
