Before you send

A 10-minute setup that takes you from “free signup” to “first production send” with your own domain. Skip this if you only want a 30-second test — see Path A instead.

The free plan unlocks the full Brixus365 product: raw HTML, batch send, SMTP, your own domain, and the Spark campaign dashboard. But because it sends from your own brand (not ours), there’s a small setup checklist before your first email goes out.

This page walks through it. Total time: about 10 minutes, mostly waiting on DNS.

1. Sign up free

Go to app.brixus365.com/signup and create an account.

You’ll need:

• A real email address (we send a 6-digit verification code)
• A name and company name (used to label your tenant)
• A password (8+ chars)

After signup you’ll be sent a verification email with a one-time code. Enter it on the next screen and your account is active.

2. Create an API key

In the dashboard, go to Settings → API Keys → Create new.

You’ll see four presets. Pick the one that matches what you’re doing:

Give the key a descriptive name (e.g. production-backend, staging-worker) and click Create Key.

The full key value (bx_live_…) is shown once, immediately after creation. Copy it now and store it securely — there’s no way to retrieve it later. If you lose it, revoke and create a new one.

export BRIXUS_API_KEY=bx_live_your_key_here

3. Verify your domain

Brixus365 needs proof that you’re authorised to send from a domain before it’ll dispatch email under it. This is a one-time DNS setup.

In the dashboard, go to Settings → Email Setup → Custom Email Domains and click Add Domain.

1. Enter your sending domain (e.g. mail.yourbrand.com or yourbrand.com)
2. The dashboard shows a list of DNS records to add — typically two TXT records (SPF + DKIM)
3. Add those records at your DNS provider (Cloudflare, Route 53, Namecheap, etc.)
4. Click Verify Domain in the dashboard

Verification usually completes within a few minutes once DNS has propagated. Larger providers can take up to an hour. The dashboard shows a green Verified badge when it’s done.

4. Set a default sender

This is the step everyone forgets. Verifying a domain isn’t enough — you need at least one sender address marked as your default before the API will accept sends.

In Settings → Email Setup → Sender Addresses:

1. Click Add Sender
2. Enter the address you want to send from (e.g. hello@yourbrand.com) and a display name
3. Click the verification link in the email that gets sent to that address
4. Once verified, click Set as Default

That’s it — you’re ready to send.

Verify the setup works

Run the same starter-template send as in the Quickstart — but with your bx_live_… key:

1curl -X POST https://app.brixus365.com/api/v1/emails \
2-H "X-API-Key: $BRIXUS_API_KEY" \
3-H "Content-Type: application/json" \
4-d '{
5  "to": "you@example.com",
6  "starterTemplate": "welcome",
7  "variables": { "name": "You", "app_name": "Your Brand" }
8}'

A successful response:

{
  "messageId": "dceaaa96-a806-43d2-ac2d-8396bbd3188a",
  "status": "queued",
  "from": "hello@yourbrand.com"
}

The from field reflects whichever sender address you marked as Default in step 4.

Common errors

If something didn’t work, the response will tell you exactly which step is incomplete:
