EmailQo's free Email Infrastructure Grader checks SPF, DKIM, DMARC, and MX records in seconds, scoring deliverability out of 100 with no signup required.
The Email Infrastructure Grader is a free diagnostic tool published by EmailQo, a company that otherwise sells cold email outreach software. Enter a domain and the tool checks four core deliverability signals: SPF, DKIM, DMARC, and MX records, each worth up to 25 points, for a combined score out of 100. No account or signup is required to run the scan.
EmailQo positions the grader as a first step before using its paid product. The underlying business is a cold email platform built around a customer's own sending infrastructure (AWS SES, Gmail, or Outlook) rather than shared IPs, on the argument that shared-IP tools are more prone to spam-folder placement. The grader exists to surface the authentication problems that its paid monitoring and warmup features are designed to fix.
The grader itself is narrow by design: it checks SPF alignment, DKIM signing, DMARC policy strength, and MX record validity, then translates the result into a plain-language score band (above 80 is solid, 50-79 has gaps, below 50 means mail is likely landing in spam). This makes it useful as a quick health check even for people who never buy EmailQo's paid product.
Behind the free tool sits EmailQo's paid cold email platform, which adds inbox warmup, blacklist monitoring, spam scoring on every send, A/B testing, IMAP reply detection, and AI-based reply classification, plus hands-on setup help for connecting AWS SES on its higher tier.
The Email Infrastructure Grader itself is completely free with no signup and no usage limit disclosed. It functions as a lead-generation and content-marketing tool rather than a standalone paid product.
EmailQo's underlying cold email platform is a separate paid product with three tiers: Starter at 19 dollars per month (5 sender accounts, 10,000 contacts, 200 verifications), Growth at 39 dollars per month (20 senders, 50,000 contacts, unlimited verifications and campaigns), and Scale at 89 dollars per month (unlimited senders, contacts, and campaigns, plus hands-on AWS SES setup help). All paid plans include a 7-day free trial and a 7-day money-back guarantee, with discounts for quarterly or annual billing. Sending costs through AWS SES are billed separately and are not part of the EmailQo subscription.

Yes, EmailQo sells a separate cold email outreach platform with paid plans starting at 19 dollars per month, built around a customer's own AWS SES, Gmail, or Outlook sending accounts.
No, the grader works standalone and free; the paid platform is only needed if you want ongoing monitoring, warmup, or campaign sending features.
EmailQo charges a flat monthly subscription plus your own AWS SES sending costs, instead of the per-email or per-contact pricing common with other cold email tools.
