You Can’t See Your Own Deliverability
Email yourself a test and it lands in your inbox — everything looks fine. But your recipients are on different providers with different filters. The message that hits your Gmail inbox can sit in Outlook’s spam or Gmail’s Promotions tab. Nothing bounces, there’s no error — the send just quietly underperforms.
Dmarclytics shows the truth. One email in. Every provider’s real folder, authentication, IP reputation and the fix — out.
Reaching the Inbox Is Not Guaranteed

One send, a real mailbox at each. These seven cover the consumer and business inboxes most recipients use — Gmail, Outlook, Yahoo, Apple Mail, Microsoft, Proton and Zoho — so seed coverage goes where your audience actually is, rather than spreading thin across niche hosts. Each is read for the exact folder you landed in.
Every Signal That Decides Where You Land
Placement is the headline — but each report also shows the authentication verdict, the sending-IP reputation and an AI-written fix for every provider. The full picture an enterprise seed tool gives you, in about a minute.
The real folder at every major provider
We deliver your email to a live seed mailbox at each provider and read the exact folder it reached — Inbox, Spam, Promotions, Blocked or Undelivered — side by side, with the authentication verdict on every row.
Why Outlook went to spam:DKIM failed and DMARC isn't aligned. Fix DKIM and placement flips to inbox.
Promotions is not the inbox
Landing in Gmail’s Promotions tab still counts as “delivered.” We flag the Promotions tab separately from the Primary inbox, so a campaign that looks delivered isn’t quietly underperforming.
Delivered — but filed under Promotions, not Primary, where it typically sees far lower engagement.
The exact check that filtered you
Per-provider SPF, DKIM and DMARC verdicts, each translated into plain English — so you see precisely which check failed, on which mailbox, instead of guessing.
Sending IP is authorized in your SPF record.
No valid signature — Outlook can’t verify the message is really from you.
Nothing aligns, so your policy can’t vouch for the message.
198.51.100.24 is listed on SpamCop — request delisting.
The fix: publish a DKIM signature, delist the IP, then re-test.
Reputation checked against the major blocklists
We pull the sending IP from your message headers and check it against Spamhaus, Barracuda, SpamCop and more — so a quiet blocklisting can’t sink your delivery unnoticed.
Not just “you’re in spam” — what to do
Guardian AI reads each failing result and writes the fix in plain English, ranked by impact, with the failing IP, record or alignment issue called out directly.
Your email reached Outlook's spam folderbecause the message isn't fully authenticated. Fix these in order of impact:
No valid DKIM was found. Add the DKIM record from your ESP so Outlook can verify the message.
SPF passes but isn’t aligned with your From domain. Once DKIM signs, DMARC will align and pass.
198.51.100.24 has a SpamCop listing. Reduce volume for 48h and request delisting.
Every fix re-tested and tracked over time
Name each test, group them into folders, and watch the inbox rate climb version over version as you fix authentication — proof the change worked, not a guess.

Send one email
From your normal sending tool, send a single email containing the test ID to all of the seed addresses. That's the only thing you do.
- 03
We read every mailbox
We check each seed inbox, record the exact folder your email reached, and pull the SPF, DKIM, DMARC, sending-IP and blocklist result behind it.
- 04
See placement and the fix
Get a per-provider report showing where you landed and why — with each issue linked to the tool or AI recommendation that resolves it.
Real Inboxes. Real Verdicts. No Black Box.
Most “spam checkers” predict a score by scanning your content. This is different: we measure where a real message actually lands, then show the signals behind it. Here is why the result is trustworthy.
Real seed inboxes, not simulations
We deliver your email to live mailboxes at each provider and read the actual folder it reached. There is no spam-filter emulation and no predictive scoring — you see the same result your recipients would.
Built by a DMARC monitoring platform
Dmarclytics monitors DMARC, SPF and DKIM for domains every day. Inbox placement testing runs on the same authentication signals we already track, applied to a single send.
No account, nothing from your list
The free test needs no signup and is identified by a one-time test ID. You send to our seed addresses — we never touch your real recipient lists or connect to your mailbox.
See it for yourself in about 60 seconds
You do not have to take our word for it. Run a real test now and read the per-provider report the product generates. Proof beats assertion.
A Clear Path Back to the Inbox — and a Way to Hold It

Guessing vs. Knowing
Common Questions
What is an inbox placement test?
An inbox placement test sends your email to a set of real seed mailboxes across the major providers and reports exactly where each copy landed — Primary inbox, Promotions, Spam, Blocked or Undelivered. Unlike a content-only spam checker that predicts a score, a placement test is empirical: it shows what Gmail, Outlook, Yahoo and the rest actually did with your message.
Why does my email land in spam on Gmail but reach the inbox on Outlook?
Each provider runs its own filters, reputation systems and authentication checks, so the same message is judged differently at each one. Outlook leans heavily on its own sender reputation network, while Gmail weighs recipient engagement and its tab system. That is why testing a single mailbox is misleading — an inbox placement test sends to seed mailboxes at every major provider and shows where each copy actually landed.
What is a good inbox placement rate?
A strong sender aims for inbox placement in the low-to-mid 90s percent across major providers. For context, Validity's 2024 Email Deliverability Benchmark put the global average around 84%, meaning roughly one in six emails never reaches the inbox. If your placement sits below the mid-80s, authentication, sending-IP reputation or recipient engagement is usually the cause.
What is the difference between a spam score and inbox placement?
A spam score is a prediction: a tool scans your content and authentication and estimates how spammy the message looks, often against a filter like SpamAssassin. Inbox placement is a measurement: the email is actually sent to seed mailboxes and the real folder it reached is recorded at each provider. A good spam score is encouraging, but only placement testing tells you what mailbox providers really did with the message.
Why do emails go to the Promotions tab instead of Primary in Gmail?
Gmail sorts incoming mail into tabs, and bulk or marketing-style messages are frequently filed under Promotions. It still counts as "delivered," but the Promotions tab typically sees far lower engagement than Primary, so a campaign can look delivered while quietly underperforming. We flag the Promotions tab separately from the Primary inbox so you can see it before you send at scale.
Does passing SPF, DKIM and DMARC guarantee I reach the inbox?
No. Authentication is necessary but not sufficient: it gets you past the gate, but content, sending-IP reputation and recipient engagement decide the rest. Passing SPF, DKIM and DMARC with a clean sending IP is the single biggest lever you control, which is why an inbox placement test shows the authentication verdict alongside the actual folder at every provider.
How do the Google and Yahoo bulk sender requirements affect deliverability?
Since February 2024, senders of more than 5,000 messages a day to Gmail must authenticate with SPF, DKIM and DMARC, offer one-click unsubscribe, and keep their spam-complaint rate in Postmaster Tools below 0.3%. Yahoo enforces equivalent rules. Failing them means throttling or spam placement, so an inbox placement test that shows your per-provider SPF, DKIM and DMARC verdict is a direct way to confirm you meet the requirements before you send.
