How It Works

Gmail Reputation Visibility in Three Steps

Connect once, monitor forever. No complex setup, no manual report checking.

Step 1 Connected

Connect Google Postmaster Tools

Authorize your domain in Google Postmaster Tools and link it to InboxEagle. Your reputation data starts flowing in under 60 seconds.

Step 2 Monitoring

Monitor domain & IP reputation

Track your Gmail domain reputation (High / Medium / Low / Bad) and IP reputation side by side — with historical trends and alert thresholds.

Step 3 Protected

Act before reputation drops

Get alerted the instant your Gmail reputation dips, with AI-generated diagnostics pointing to the exact cause — spam complaints, authentication failures, or volume spikes.

Features

Visual reputation gauge showing your current Gmail domain score — High, Medium, Low, or Bad — with animated trend sparkline over the last 90 days.

FAQ

Frequently Asked Questions

What is Google Postmaster Tools and what data does it provide?
Google Postmaster Tools is a free service by Google that gives high-volume senders insight into how Gmail treats their emails. It provides domain reputation (High/Medium/Low/Bad), IP reputation, spam rate, authentication pass rates, delivery errors, and encryption rates. InboxEagle connects to this API and surfaces the data in a more actionable, real-time dashboard with alerting.
What Gmail spam rate threshold should I be worried about?
Google's Email Sender Guidelines recommend keeping your spam rate below 0.10% (1 complaint per 1,000 emails). At 0.30%, Gmail may begin throttling or blocking your mail. InboxEagle monitors your spam rate continuously and warns you before you approach these thresholds.
How is Gmail domain reputation different from IP reputation?
Domain reputation reflects Gmail's long-term assessment of your sending domain — built up over months of sending history. IP reputation reflects the specific server IP sending on your behalf. You can have a High domain reputation but a Low IP reputation if you recently switched ESPs or sending infrastructure. InboxEagle tracks both independently.
How quickly do InboxEagle alerts fire when my Gmail reputation drops?
InboxEagle checks your Google Postmaster data every minute and fires alerts within 1 minute of any configured threshold being breached. Alerts include the specific metric that changed, the before/after values, and AI-generated diagnostic context.
Do I need a Google Postmaster Tools account already set up?
Yes — you need an active Google Postmaster Tools account with your domain already verified. InboxEagle then connects to Postmaster via OAuth and imports your data automatically. Setup takes under 60 seconds once your Google account is authorized.
