Out of 100,000 emails the average online store sends, only 60,000 to 70,000 actually land in someone's inbox. The remaining 30,000–40,000 end up in Spam, in Promotions, or just silently disappear.

The worst part: your sending platform shows "Delivered: 99%" in both cases. So you assume everything's fine. And half your email budget burns in the dark.

Here's why this happens — and how to check your campaigns for free in five minutes.

Why "Delivered" doesn't mean "in the Inbox"

When your sending platform (Mailchimp, SendGrid, Brevo, Klaviyo — any of them) reports "Delivered: 99%," it's saying one technical thing: the recipient's mail server replied with "OK, accepted your message."

What happened next, the platform doesn't know. And four very different things can happen:

• Inbox — what you actually want
• Spam / Junk — formally delivered, but no one will see it
• Promotions tab (Gmail) — they'll see it, but open rates drop 3–5x
• Silently dropped — the recipient's anti-spam decided it's junk and quietly deleted it. No trace anywhere.

All four scenarios look identical in your dashboard: 250 OK, delivered, green checkmark.

What a real check showed

One of our clients — an ecommerce store — was sending monthly campaigns to 100,000 subscribers. The sending platform reported "Delivered: 99.2%." Open rate: 18%. Looked perfectly fine.

When we ran a real inbox-placement test, here's what came back:

• Gmail: 88% in the inbox
• Outlook: 76%
• Yahoo: 71%
• AOL: 64%

So the real audience actually seeing the campaign was around 70,000 people — not 99,200. A third of subscribers, month after month, were getting filtered into Spam without anyone knowing.

After fixing authentication and simplifying the email layout, the average inbox rate went from ~75% to ~89%. Open rate climbed from 18% to 27%. All from one 5-minute test before pressing send.

How to check your own campaigns — free

We built a free service that does this:

check.live-direct-marketing.online

It tests your email across 9 major mailbox providers in one go: Gmail, Outlook (Microsoft 365 / Hotmail / Live), Yahoo, iCloud, AOL, GMX, T-Online, Mail.ru, Yandex. No signup, no card, no trial.

Three steps:

1. Open check.live-direct-marketing.online and enter your sender address (the one you send from).
2. The service generates unique test addresses on each provider. Paste them as recipients in your sending platform and send your real campaign email — one normal send.
3. Within 30 seconds to 5 minutes, the report shows up live: where each provider placed the email, what spam filters saw, and whether your authentication (SPF, DKIM, DMARC) passed. Downloadable as PDF.

If your inbox placement is 85% or higher across the board — green light, send the campaign. If lower — you'll see exactly what to fix before burning the budget.

Bonus: free domain monitoring

You can also enable continuous monitoring of your sender domain — also free. Every 6 hours the system checks SPF, DMARC, MX records, TLS certificate validity, and major blocklists. If anything breaks, you get an email alert within hours instead of finding out a week later from dropped open rates. Up to 3 domains per account, no card required.

Try it before your next send

If you've got a campaign going out this week — spend 5 minutes on this before pressing send. You might find that a third of your subscribers haven't been seeing your emails for months. Better to know now than after.
