An email deliverability test checks whether your sender domain, campaign list, reputation metrics, and email content are ready for the inbox. Enter your sending domain and pre-send metrics to get a 100-point readiness score with prioritized fixes.
The technical checks use live DNS lookups through MailParse's email authentication scorecard. Campaign inputs run in your browser so you can test launch emails, newsletters, and lifecycle campaigns without storing the plan.
SPF, DKIM, DMARC, MX, BIMI, and TLS-RPT DNS readiness
Bounce rate, complaint rate, and recent open-rate risk
Opt-in quality, list age, unsubscribe path, and send volume
Spam-trigger testing and branded tracking-domain alignment
An email deliverability test checks whether a campaign has the technical, reputation, content, and list-health signals needed to reach the inbox instead of spam. It does not guarantee inbox placement, but it shows the biggest issues to fix before sending.
The score combines domain authentication, list quality, sender reputation, and content readiness. SPF, DKIM, DMARC, MX, BIMI, and TLS-RPT come from live DNS checks, while bounce rate, complaint rate, unsubscribe handling, permission source, list age, and content risk come from the campaign inputs.
A score of 85 or higher is a strong pre-send signal. Scores from 70 to 84 are workable but need cleanup. Anything below 70 means you should fix authentication, list quality, or spam-risk issues before sending to a large audience.
No. Actual inbox placement depends on mailbox-provider reputation and recipient engagement history. This test is a pre-send readiness check that catches the most common problems before they hurt Gmail, Outlook, Yahoo, and corporate inbox placement.
No. The campaign inputs are evaluated in your browser. Domain DNS checks call MailParse's lookup endpoint, but email content, list metrics, and campaign notes are not stored.
Get an A+ to F grade for SPF, DKIM, DMARC, BIMI, MX, and TLS-RPT.
Scan subject lines and email copy for spam triggers and risky formatting.
Check whether your domain or sending IP appears on common blocklists.
Validate SPF syntax, lookup count, and weak mechanisms.
Look up your DMARC policy and reporting configuration.
Plan a safer volume ramp for new domains, IPs, or sender identities.
MailParse receives inbound messages, parses MIME, and returns authentication results as structured JSON so your app can monitor email quality automatically.
