We build your company's own HTML email tool on your server.
The CodingDoGG™ engine, customized for you.
Customer lists never leave your company — multiple staff can use it together.
Installed on your server / Shared by staff (with roles) / All data stays on your server
Who it's for
For companies that need a dedicated tool aligned with their operations, brand, and security — not a generic SaaS.
Law firms, consultants, associations — anyone who sends polished HTML email to a defined audience on a schedule.
Installed on your server; each person uses it in the browser. Role-based access splits create, edit, and send permissions.
You don't want customer data on external SaaS. Everything stays on your server; sending uses your own accounts.
Why custom-built
Sending runs from your server and accounts. No shared infrastructure — independent reputation, no collateral damage from other senders.
Source files and lists stay on your server. No external SaaS — you keep data sovereignty while staff share the tool.
We reuse the existing production engine that outputs break-resistant HTML — faster delivery and lower cost than building from scratch.
What we build
Multi-user features (shared by staff)
Add & remove staff accounts (admins only)
Only administrators can create or delete accounts.
Edit, save & manage newsletters (all staff)
Each person creates and manages newsletters in their own account.
Share finished newsletters with colleagues
Recipients get an independent copy in their account — they can save, manage, and send it themselves.
Standard (engine + server install)
Option (full delivery tool)

We don't guarantee "always delivered." Results depend on your sending setup and authentication — we can advise, but you configure it.
The "Standard" package supports it; ongoing deliverability is your responsibility. Smaller direct sends can use a leaner build.
