Validify’s Email Health Check gives you a thorough diagnostic of your sending environment—so you can catch misconfigurations, improve deliverability, and prevent issues before they start.
Hidden issues in your setup — from domain records to server settings — can cause emails to bounce, land in spam, or erode your sender reputation over time. A routine health check helps catch these problems early, before they impact deliverability or security.
The Validify Email Health Check includes comprehensive diagnostics across all critical layers of your email infrastructure—domain setup, server configuration, authentication protocols, and blacklist presence.
We verify that your domain’s MX (Mail Exchange) records are correctly configured, ensuring your email server is reachable and your messages can be delivered as expected.
We track how your SPF and DKIM records are performing across all email sources. You’ll be alerted to any misalignment issues that could cause legitimate messages to fail authentication or land in spam.
We validate your domain’s SPF and DKIM records to ensure that your messages can be authenticated by receiving mail servers. We also verify DMARC alignment and offer guidance on proper DMARC policy setup.
We scan over 100 trusted blacklists to check whether your sending domain or IP is currently included, arming you with information critical to protecting your sender reputation and fixing deliverability issues.
Validify’s Email Health Check is a diagnostic audit of your sending environment designed to catch misconfigurations (domain records, server settings, authentication) that can cause bounces, spam placement, or gradual reputation damage—before they create a visible deliverability problem.
It audits the critical layers called out on the page: MX record verification, SMTP record validation with open relay tests, SPF/DKIM validation plus DMARC alignment verification and policy guidance, and a blacklist scan across 100+ trusted lists for your domain or IP.
An open relay is an improperly configured SMTP server that allows unauthenticated third parties to relay mail through it—often abused for spam/phishing, which can quickly lead to blacklisting and reputation damage. Validify includes open relay tests to catch this high-impact security/deliverability risk early.
MX records are DNS records that direct email to the correct mail server for a domain. If MX is missing or misconfigured, inbound routing and verification behaviors can break, and you can see failures that look like deliverability issues. Validify explicitly verifies MX records to ensure your server is reachable and routing behaves as expected.
Validify validates SPF/DKIM so receiving systems can authenticate your mail, and it verifies DMARC alignment and provides guidance on DMARC policy setup—reducing authentication failures that commonly correlate with spam placement and blocking. This also maps directly to bulk-sender expectations from major providers (Google and Microsoft both require SPF/DKIM/DMARC compliance for high-volume sending).
Run it any time you make changes that can quietly break deliverability—switching ESPs, changing DNS/authentication, adding new sending domains/subdomains, moving to new infrastructure, or after a sudden performance drop. The page positions health checks as preventative diagnostics to catch hidden issues early, so making it part of your routine (monthly/quarterly, plus after major changes) is a practical best practice.
