The Problem

Every new client costs you more.
That's not a business model—it's a trap.

$120K per year

The SaaS Tax

A 10-client agency pays $500-$1,000 per client monthly. That's money leaving your business forever.

100% at risk

Platform Dependency

Your client lists live on someone else's servers. One policy change and you're locked out.

0 differentiation

Commodity Status

No white-labeling. No customization. You're reselling the same platform as everyone else.

There's a different path.

The Solution

Stop renting.
Start owning.

01

Economics

One payment. Forever yours.

Replace $60-120K/year in SaaS fees with a single $20K investment. Scale from 10 to 50+ clients without adding platform costs.

$400K+
5-year savings
02

Ownership

Your server. Your rules.

Self-host on AWS, DigitalOcean, or any cloud. Route through any ESP. No account suspensions. No platform dependency.

100%
control
03

Differentiation

Your brand. Not theirs.

Full white-labeling with your logo, domain, and custom features. Position as a tech company, not a reseller.

Octeth v5.9.3 Released: 258 Fixes, Account Usage APIs, and Why We're Telling You the Number

Octeth v5.9.3 ships today, and it's a hardening release: 258 of its 269 changes are fixes. We spent the cycle auditing our own API surface rather than adding features, and we're publishing the full accounting — because when you host your own platform, you get to see what a maintenance release actually contains. It also brings account usage APIs for agencies who bill on sending volume, spreadsheet-safe CSV exports, and delivery workers that recover on their own.

It also brings campaign reporting APIs for building your own client dashboards, automated bot and proxy activity detection so your engagement numbers reflect real humans, and much faster email search on large lists.
