Knowledge Base & Operational DocumentationWhy Does Email From a Website Form Land in Spam After a Domain Change?
11/10/2026
After a domain change, website-generated mail may use an unaligned sender or missing authentication records. Delivery can vary by recipient provider.
What to check
Inspect message headers, envelope sender, From domain, SPF and DKIM alignment, DMARC policy, and the site’s SMTP configuration. Check whether the new domain is authorized.
Recommended next step
Use authenticated sending with aligned identities and test across recipient providers. Informatix Systems can troubleshoot domain, DNS, and email delivery.
