How Peeker Helps Marketers
Convert Better
01
Inbox Placement Tracking
See exactly where your emails land across every connected inbox so you can diagnose deliverability issues with proof, not guesses. When placement shifts, you'll know what changed and where to focus.
02
Catch Dips Early
Monitor inbox performance trends and early warning signals that typically affect campaign results. Catch underperforming senders early, so you fix the actual bottleneck before it hits your campaigns.
03
Scale Safely
As volume increases, a few weak inboxes can drag down everything. Peeker helps you isolate low performers and automatically rotate them out, keeping your sending pool healthy while you scale.

Frequently Asked Questions
Everything you need to know before getting started with Peeker.
Campaign analytics focuses on campaign performance (opens, replies, conversions) while Peeker focuses on inbox performance, why emails might not be landing, and what’s putting your sending at risk.
You see metrics like inbox placement rate, spam placement rate, inbox health rate, and domain health.
Yes, Peeker flags inboxes with declining health or unusual drops in engagement(reply rate)
No, it won’t. If a risky inbox is swapped, there may be a brief pause, but the goal is to keep overall volume steady while keeping deliverability high.
Immediately, once your inboxes are connected, you get visibility into deliverability + health, and the automations start preventing issues (disconnects, burn signals) before they impact results.
