Three traps your ESP set for you
The Success Tax
Your costs rise as your database grows. Even for contacts you never email. The more successful you are, the more you pay.
The Bad Neighbor Risk
Shared IPs mean your reputation pays for other senders' mistakes. One bad actor on your shared infrastructure can tank your inbox placement.
The Black Box
Vanity metrics. No real visibility into inbox placement by provider. You see open rates. You don't see that 30% of your emails never reach the inbox.
Your emails have a brain behind them
Sendability doesn't just send. It acts. Each agent handles a critical layer of your email infrastructure autonomously.
Each layer works independently. Use the full platform, or deploy just the layers you need.
Deliverability Agent
Gmail reputation drops to Low. Sendability automatically reduces volume 75%, switches to engaged-only segments, monitors recovery, and alerts you after stabilization.
You notice open rates dropped. You open a ticket. You wait.
The agent handled it before you checked your dashboard.
Data Quality Agent
A spam trap enters your database. Caught at point of capture. Your sender reputation stays clean. No manual list cleaning. No monthly "hygiene" ritual.
You send to bad addresses until your bounce rate spikes.
Invalid contacts never enter your database.
Infrastructure Agent
Multi-MTA routing decisions happen per-tenant, per-mailbox-provider, in real-time. KumoMTA primary. SparkPost, SES, qMail as overflow.
One shared pool. No routing intelligence.
Intelligent routing optimizes delivery per mailbox provider.
Content Agent
BrandExpand generates SEO-optimized articles in your brand voice, on schedule, across languages. Your content pipeline runs without manual intervention.
You write everything. Or you stop publishing.
Consistent, brand-aligned content at scale.
The math your ESP doesn't show you
Sendability includes managed infrastructure, deliverability management, analytics, and human operator support.
