Where Email Breaks for Companies That Send on Behalf of Others

One Bad Sender, Everyone’s Problem

A compromised customer, tenant, or agent can damage your sending reputation and put every other sender’s mail at risk.

Support Tickets You Can’t Afford

Blocklisted IPs, missing transactional emails, and delivery questions consume engineering and support hours that should go to product.

Abuse Operations You Don’t Want to Build

Detecting compromised accounts, tuning rate limits, and handling complaints is a full-time function — and a hard one to staff.

Battle-Tested Where Email Abuse Is Hardest

We learned email abuse in the hardest environment on the internet — web hosting — and we bring those operations to the platforms, SaaS apps, and AI-agent companies that need them now.
Prevent Email Blacklisting

Spam, Virus, and Phishing Protection

Identify spam bursts, phishing attempts, and malware before they leave your network — protecting your sending reputation in real time.
Email Domains On Preferred Ips

Per-Sender Reputation Controls

Track behavior at the individual sender level — not just per account — and isolate problems before they spread across your platform.
Detect Compromised Accounts

Automated Abuse Response

Detect compromised accounts and trigger webhook-driven rate limits, suspensions, or alerts — without manual intervention.
