Email setup 70/100

SPF / DKIM / DMARC above reflect the last 1 email we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to dmarcly.com. Policy p=reject means receivers actively block or quarantine spoofed mail.

SPF alignment: all 6 observed emails use a return-path aligned with holaluz.com (mandrill.holaluz.com, bounce.holaluz.com). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 4 observed emails sign with a domain aligned with holaluz.com (holaluz.com). DKIM authenticates the visible From — supports DMARC directly.

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.
