Tested Against Real Seed Mailboxes at Top Providers
Add your sending domain and fire off a single test to PowerDMARC’s seed mailboxes. No SMTP or DNS changes needed.
We validate SPF, DKIM, and DMARC while measuring inbox placement across all six providers.
Receive a Domain Security Score, per-provider placement breakdown, and a prioritised list of fixes with DNS examples. Pair it with our email deliverability best practices for long-term wins.
Even with SPF, DKIM, and DMARC in place, messages land in spam, promotions, or get blocked entirely. Placement depends on far more than authentication, and most teams only find out after a campaign goes out.
Gmail, Outlook, and Yahoo each weigh signals differently, so the same message can land in three different places.
A history of complaints, bounces, or spam traps quietly drags placement down even on a clean send.
Missing one-click unsubscribe headers now breaks Google and Yahoo bulk sender rules and hurts placement.
That is the gap an email deliverability tester closes: see exactly where your mail lands, and why, before you hit send.
An email deliverability tester is a diagnostic tool that simulates a real-world send to multiple inbox providers and tells you exactly where your message landed: inbox, spam, promotions, or blocked entirely. Instead of guessing why open rates dropped after a campaign goes out, an inbox placement test gives you that visibility before the send, so you can fix authentication gaps, content triggers, or reputation issues in advance.
PowerDMARC's tester goes a step further by combining inbox placement data with full SPF, DKIM, and DMARC validation in a single workflow, covering the full scope of email deliverability testing without bouncing between standalone tools.
Detect. Decide. Stay in control.
A composite colour-coded 0–100 score rolled up from your SPF, DKIM, and DMARC posture — giving you an instant read on how well your domain is protected.
