Find Out If Your Emails Are Going To Spam Using Our Free Tool:
What Is The Inbox Placement Rate?
An inbox placement test sends your email to a set of real seed mailboxes across major providers and reports where each copy landed: primary inbox, spam, or not delivered. Your sending tool only confirms that the receiving server accepted the email. It has no idea where it went after that. An email can show as delivered in your dashboard while sitting in spam right now. This test shows you the part your dashboard hides.
How the Inbox Placement Test Works
1. Copy the seed address: Use the test address shown in the tool above.
2. Send your real email: Use your actual domain, sending tool, and the exact email you plan to run.
3. Check your results: See where your email landed across Gmail, Outlook, Yahoo, and others.
4. Fix what is dragging you down: The results point to what needs fixing before your real send goes out.
Why It Matters
Delivered Does Not Mean Seen
Your sending dashboard shows green the moment a receiving server accepts the email. That tells you nothing about where it went next. It could be sitting in spam right now and you would never know from a delivery report. The Inbox Placement Test shows you the actual result: primary inbox, spam, or not delivered, across every major provider.
Find the Leak Before It Costs You
Low inbox placement is rarely one problem. It is usually a mix of missing authentication, a domain that was not warmed up before scaling, copy that triggers filters, volume that ramped too fast, or low engagement from earlier sends. The test tells you which of those apply to your setup so you fix the actual cause instead of guessing and hoping the next campaign does better.
Test Regularly, Not Just Once
Inbox placement shifts as your domain reputation changes and provider filtering rules update. A test from two months ago is not an accurate picture of where you stand today. Run one before any new campaign, before scaling on an existing domain, and on a regular cadence while actively sending. Catching a decline early is far easier than recovering after your reputation has already taken a hit.

What is inbox placement rate?
It is the percentage of your emails that reach the primary inbox rather than spam or nowhere. A 99% delivery rate means nothing if 40% of those delivered emails land in spam and never get seen. Inbox placement rate is the number that actually tells you whether your outreach is working.
Why are my emails going to spam?
Usually a combination of things: missing or broken SPF, DKIM, or DMARC; a domain that was not warmed up before scaling; spam-trigger words in your subject line or copy; volume that spiked too fast; or low engagement from earlier sends in the same campaign. The test helps narrow down which of these is affecting you.
How do I improve my inbox placement rate?
Authenticate every sending domain with SPF, DKIM, and DMARC. Warm new domains before you scale. Keep volume gradual. Clean your copy of spam-trigger phrases. Maintain list hygiene so bounce rates and complaint rates stay low. Re-test after each change to confirm it worked. Warmforge handles warm-up and reputation monitoring automatically if you want that side covered.
How often should I run an inbox placement test?
Before any new campaign or domain launch. Before scaling volume on an existing domain. And on a regular cadence while actively sending. One test at setup is not enough because placement drifts over time as your reputation and provider rules change.
What is the difference between this and the Email Deliverability Test?
The Inbox Placement Test shows where your emails land across providers. The Email Deliverability Test checks the underlying health of your mailboxes and domains, including authentication setup, blacklisting status, and configuration issues. Use them together. The placement test shows you the symptom, the deliverability test helps find the cause.

The blog post discusses the importance of email warm-up for high volume email senders. Email warm-up is the process of gradually increasing the volume and frequency of your email sends over a period of time, which helps to establish trust with the ESPs and ISPs and reduces the likelihood of your emails being flagged as spam or blocked

The Inbox Placement Rate is a critical metric that measures the percentage of emails that successfully land in the primary rather than the spam folder or getting lost entirely. The answer to why inbox placement tests are necessary is straightforward: understanding deliverability is essential for effective email marketing. Unlike basic email delivery rates, which only confirm whether an email was sent, the inbox placement rate tells you where your emails actually end up - whether they reach the recipient’s inbox, get flagged as spam, or go missing.
By understanding your Inbox Placement Rate, you can optimize your email strategy, detect deliverability issues early, and take action to improve your chances of reaching your audience effectively. Whether you’re running cold email campaigns, newsletters, or transactional emails, knowing where your messages land is essential for maximizing engagement and conversions by ensuring your customers actually see your emails.
