📘 Frequently Asked Questions
Even legitimate emails get flagged when SPF, DKIM, or DMARC records are missing or misconfigured. Inbox providers cannot verify your identity — pushing messages to spam automatically.
Use our SPF Checker, DKIM Checker, and DMARC Checker tools to find missing or incorrect records. Then update them in your DNS and re-test.
No. MailTested provides a technical risk score based on authentication, reputation, reverse DNS, and SpamAssassin. It does not log in to provider inboxes or guarantee placement.
Authentication (SPF/DKIM/DMARC), IP reputation, content spam triggers, and blacklist status all affect your score.
WHAT THE TEST MEASURES
One email, six practical deliverability checks
DMARC alignment
See whether the authenticated identities align with the visible From domain.
IP reputation
Check the connecting IP against major DNS-based blocklists.
Reverse DNS
Validate PTR, forward lookup, and HELO hostname consistency.
SpamAssassin
Review the spam score, threshold, and individual rules triggered by the message.
Action plan
Get focused explanations for failed checks and what to correct before sending again.
📨 Why Email Deliverability Matters
Email providers like Gmail, Outlook, and Yahoo filter aggressively. Missing SPF, DKIM, or DMARC records make your domain look suspicious — even if your messages are legitimate.
MailTested helps identify technical gaps, improve authentication, and boost trust so your business emails reach inboxes consistently.
