Who it's for

"We want our own tool —
built properly."

For companies that need a dedicated tool aligned with their operations, brand, and security — not a generic SaaS.

1

Regular email to clients & members

Law firms, consultants, associations — anyone who sends polished HTML email to a defined audience on a schedule.

2

Teams that share one tool

Installed on your server; each person uses it in the browser. Role-based access splits create, edit, and send permissions.

3

Data must stay in-house

You don't want customer data on external SaaS. Everything stays on your server; sending uses your own accounts.

Why custom-built

Dedicated means safer and cleaner

Your own sending environment

Sending runs from your server and accounts. No shared infrastructure — independent reputation, no collateral damage from other senders.

All data on your server

Source files and lists stay on your server. No external SaaS — you keep data sovereignty while staff share the tool.

Proven engine, reused

We reuse the existing production engine that outputs break-resistant HTML — faster delivery and lower cost than building from scratch.

What we build

What goes into your custom tool

Only administrators can create or delete accounts.

2

Edit, save & manage newsletters (all staff)

Scope & responsibility

Scope & responsibility (important)

We are the tool builder and provider. Sending, infrastructure, and legal compliance of content remain your company's responsibility.

  • Sending infrastructure, server, and accounts — provided by you.
  • SPF / DKIM / DMARC / PTR and deliverability setup — your side.
  • Consent, sender disclosure, unsubscribe — your operations.
  • We do not guarantee delivery — it depends on your sending environment and reputation.

This scope keeps the engagement clear and safe. Details are documented in your quote and contract.

FAQ

Common questions

Q. Do you guarantee deliverability?

We don't guarantee "always delivered." Results depend on your sending setup and authentication — we can advise, but you configure it.

Q. Can we send bulk mail?

The "Standard" package supports it; ongoing deliverability is your responsibility. Smaller direct sends can use a leaner build.

Q. Where are customer lists stored?

On your server. Data is designed to stay in your infrastructure — not on external SaaS.

Q. How many users? Can roles differ?

Multiple staff can share the tool. We issue logins and set create / edit / send roles per your org (designed to your headcount).

Q. Can we use our existing mail setup?

Yes. We connect to your SMTP / sending stack — no need to buy a separate sending server.

Q. Server requirements?

Typical shared hosting works (PHP 7.4–8.x, mbstring, GD, cURL, HTTPS). We can review and help with installation.
