What is Inbox Tracker?

Your email's journey doesn't end at "sent"

Inbox Tracker is an advanced Mailercloud add-on that monitors your email delivery performance and inbox placement across major email providers. It tells you exactly what happened to your email after it left your server.

Built for Deliverability Excellence

Total visibility into every email's journey

Four powerful capabilities that give you the insight to protect your sender reputation and improve campaign performance — campaign after campaign.

Inbox Placement Tracking

Know the exact fate of every email you send

Every email you send goes one of three places — and only one of them means your campaign was seen. Stop relying on open rates alone. The Inbox Tracker shows you the full picture in real time, so you can act before a deliverability problem becomes a performance crisis.

Inbox percentage: emails that successfully reached recipients' inboxes
Spam percentage: emails marked or filtered as spam by providers
Missed percentage: emails that were never delivered at all

Provider-Level Insights

Not just inbox or spam — know the exact tab

For Gmail and Yahoo — which together account for the majority of your subscriber base — the inbox has multiple folders. Landing in Promotions is a very different outcome from landing in Primary. Inbox Tracker shows you which tab your email ended up in so you know exactly what your subscribers are actually seeing.

Track placement across Primary, Promotions, Social, Updates and Forums tabs
Separate breakdowns for Gmail and Yahoo side by side in the same report
Spot if you're being deprioritised to Promotions before it hurts your open rate
Use tab-level data to adjust subject lines, sender name, and content strategy

Client Panel Dashboard

Spot delivery problems before they cost you

The Inbox Tracker dashboard gives you a bird's-eye view of placement performance across all your campaigns. Filter by provider, sort by spam rate, and instantly see which campaigns have a problem — so you can fix it before your next send, not after.

Filter and sort inbox placement data across all campaigns in one view
Identify which campaigns are triggering spam filters — and exactly why
Use placement trends to optimise future campaigns before you press send
All your placement data in one central place — no switching between tools
