RFC 7208 DNS Lookup Cost1 of 10 Lookups

1 direct ActiveCampaign relay include query. ActiveCampaign configures a custom CNAME mail server to align SPF with your sending domain.

Lookup Budget1/10
RECORD 1: SPFHost: @ (or apex domain)Type: TXT
v=spf1 include:emsd1.com ~all

⚠️ Important: If your domain already publishes an existing SPF record, merge include:emsd1.com into that record. Never publish two separate SPF records.

RECORD 2: DMARCHost: _dmarc (or _dmarc.example.com)Type: TXT
v=DMARC1; p=quarantine; rua=mailto:dmarc-reports@example.com; pct=100; adkim=r; aspf=r

This policy enforces p=quarantine (suspicious emails routed to spam) and directs daily XML compliance reports to dmarc-reports@example.com.
