For hosting providers, agencies & MSPs

You already run their mail.
Now sell them signatures.

Your customers are on cPanel, Plesk, DirectAdmin or Roundcube. The signature vendors they find online stop at Microsoft 365 — so those customers have no option at all. Badex Signature plugs into the SMTP you already operate, white-labelled, for one flat fee.

The part that matters

Your cost is €2.63 per client. Their price is whatever you choose.

The Reseller plan is €79/month flat for 30 client domains, with unlimited SMTP accounts and unlimited templates inside it. There is no per-mailbox meter to reconcile and no surprise invoice when a client hires five people.

30 client domains You retail at €5 You retail at €9 You retail at €15
Your revenue€150 / mo€270 / mo€450 / mo
Your cost€79 / mo€79 / mo€79 / mo
Your margin€71 / mo€191 / mo€371 / mo

Illustrative arithmetic on the published Reseller plan. You set your own retail price — we do not set it and we do not take a cut of it. Need more than 30 domains? Extra domains are available; tell us your volume.

Why this gap exists

Nobody built this for the panels you actually run

Centralised signature management grew up around Exchange and Microsoft 365. If your customer's mail lives on a shared-hosting control panel, the mainstream tools simply do not reach it. That is not a small gap — it is most of the small-business web.

How it works for you

Nothing to install on a single client device

STEP 1
Point outbound mail at us
Add Badex as the smarthost or outgoing relay on the mail server you already operate. One change, at the server, once.
STEP 2
Add client domains in bulk
Multi-tenant dashboard with bulk CSV import. Each client is isolated, with its own templates and policies.
STEP 3
Signatures are injected server-side
DKIM signed on the way out, with SPF and DMARC intact. No add-ins, no plugins, no end-user instructions, no support tickets from grandmothers.
STEP 4
Put your own brand on it
White label is available on the Reseller plan. Your customers see your product, in your hosting plan, on your invoice.

BEFORE YOU ASK

What we do not have yet

  • No WHMCS provisioning module yet. You can add and remove client domains through the dashboard and by bulk CSV import, but automated provisioning from WHMCS is not built. If that is what you need to resell at scale, say so — it moves up the list based on who asks.
  • No Plesk or cPanel extension in their catalogues yet. Setup is a documented server-side relay change, not a one-click install.
  • The Reseller plan covers 30 client domains. Beyond that, talk to us rather than guessing from the pricing page.

We would rather you find this out here than three weeks into a migration.

Try it on one client domain first

14 days, no credit card. Point one domain at us, see the signature land DKIM-signed, then decide whether it belongs in your hosting plans.
