Land in the inbox.Every single send.
SendGauge watches every signal that decides where your email lands — and warns you weeks before you ever touch the spam folder.
One number that actually means something.
Spam rate, reputation, placement, authentication, and blocklists — read continuously and reduced to a grade and a to-do list.
Connect your domain
Add a domain, link Google Postmaster and your ESP. No DNS surgery, no engineering ticket — about five minutes.
We watch every signal
Spam rate, reputation, SPF/DKIM/DMARC, blocklists, and seed placement across Gmail and Outlook — continuously.
You hear it first
A clear score, the exact issue, and the fix — pushed to you weeks before a single subscriber notices.
Not raw metrics. Interpreted intelligence.
Reputation Dashboard
Real-time spam rates, domain reputation, and authentication health from Google Postmaster — read for you, weeks before your subscribers feel the difference.
Inbox Placement Testing
Early warning, not post-mortem. Test across Gmail and Outlook to see exactly where you land — inbox, promotions, or spam — before it costs you.
DNS & Blocklist Health
Continuous, automated, always on. SPF, DKIM, DMARC, and 90+ major blocklists — so you're never the last operator to know.
Real-time alerts
Get notified the instant a blocklist appears or open rates drop — by email or Slack — so you can fix it before the damage spreads.
Smart Segmentation
Auto-segment your list by engagement to find the right email frequency for every subscriber — protecting your reputation and boosting deliverability.
Plugs into the stack you already send from.
Simple, transparent pricing.
