Raw form submissions bury your best leads without lead scoring automation. Day 9 of 30 Days of n8n & Automation reveals Alfaz Mahmud Rizve’s production workflow at whoisalfaz.me – instantly tagging Brevo contacts by intent (“demo” vs “newsletter”), source (LinkedIn vs organic), and language (EN/ES/FR).

Alfaz Mahmud Rizve deploys this across agency clients, handling 300+ daily leads. Get the exact n8n JSON import, Brevo API setup, and checklists – no manual tagging, just 35% higher campaign opens.

Building on Day 8: Capture n8n lead data from WordPress/Elementor, this adds smart segmentation.

The Lead Scoring Problem Agencies Face Daily

SaaS founders and agencies drown in untagged Brevo lists. Lead scoring automation fixes this: “Enterprise demo” requests get “hot-lead” tags for immediate sales calls; casual signups enter nurture sequences.

At whoisalfaz.me, Alfaz Mahmud Rizve saw sales teams waste 3 hours daily sorting leads. n8n + Brevo API reads form JSON on submission, applying multi-tags like [“hot-lead-demo”, “linkedin-paid”, “spanish”].

Result? Spanish leads flow to localized campaigns; LinkedIn sources trigger B2B sequences. Ties perfectly to Day 7: n8n Debugging & Error Handling for bulletproof execution.

Prerequisites: 7-Minute Setup Checklist

Verify these before starting:

n8n instance (cloud/self-hosted) with Brevo credentials.
Brevo API key: Account > SMTP & API.
Form with fields: email, intent (demo/trial/newsletter), source (linkedin/website), language (en/es/fr).
Test webhook endpoint ready.

Alfaz Mahmud Rizve tip: Use Day 6: Essential n8n Core Nodes IF nodes for branching

n8n Brevo setup for lead scoring automation by Alfaz Mahmud Rizve, prerequisites checklist visual for SaaS/agencies at whoisalfaz.me.

Step 1: Webhook Trigger – Your Form’s Smart Gatekeeper

n8n Webhook node catches every submission instantly.

Add Webhook node > Production URL mode.
Paste URL into form: Elementor > Day 8 workflow, Google Forms script, or Typeform webhook.
Expected payload: {"email":"lead@ex.com","intent":"demo","source":"linkedin","language":"en"}.

Test with one submission. Data flows to next nodes.

Step 2: Multi-Dimensional IF Nodes for Tags

Lead scoring automation uses parallel IF branches – no single-point failure.

IF Node 1 – Intent Scoring:

{{ $json.intent }} = “demo” → tags: ["hot-lead-demo"]
= “trial” → ["warm-lead-trial"]
else → ["cold-nurture"]

IF Node 2 – Source Tracking:

“linkedin” → ["paid-social"]
“website” → ["organic"]

IF Node 3 – Language:

“es” → ["spanish-lead"]

Merge outputs with Set node: {{ $json.tags.concat($node["IF Source"].json.tags) }}.

Step 3: Code Node – Dynamic Tag Builder

JavaScript merges tags into Brevo-ready array.

Copy-paste Code Node:

javascriptconst input = $input.all();
const tags = [];

input.forEach(item => {
  if (item.json.intent === 'demo') tags.push('hot-lead-demo');
  if (item.json.source === 'linkedin') tags.push('paid-social');
  if (item.json.language === 'es') tags.push('spanish-lead');
});

return [{ json: { 
  email: $json.email, 
  attributes: $json, 
  final_tags: tags.filter(Boolean) 
}}];

Output: ["hot-lead-demo", "paid-social", "spanish-lead"]. Scalable for 10+ criteria

Step 4: Brevo Create/Update – Apply Tags Instantly

Brevo Node configuration:

Resource: Contact
Operation: Create or Update
Email: {{ $json.email }}
Attributes: {{ $json.attributes }}
Tags: {{ $json.final_tags }} (array)

Brevo API auto-merges tags on existing contacts. Verify in Brevo > Contacts > Tags.

Sample Payload:

json{
  "email": "lead@ex.com",
  "attributes": {"INTENT": "demo", "SOURCE": "linkedin"},
  "tags": ["hot-lead-demo", "paid-social", "spanish-lead"]
}

Fix: Pre-create tags in Brevo UI to avoid “invalid tag” errors.

Production Error Handling (From Day 7)

Alfaz Mahmud Rizve adds retry logic post-Brevo:

IF Node: {{ $node["Brevo"].json.id }} exists?
Success → NoOp
Fail → HTTP Request (Brevo retry) + Slack alert

Code for retry:

javascript// Retry Brevo API directly
const response = await $http.request({
  method: 'POST',
  url: 'https://api.brevo.com/v3/contacts',
  headers: { 'api-key': $secrets.brevo_api_key },
  body: $json
});

Implementation Checklist – Deploy Today

Import JSON workflow from whoisalfaz.me/day9-json
Add form webhook (Day 8)
Create Brevo tags: hot-lead-demo, paid-social, spanish-lead Brevo docs
Test 5 scenarios (each intent/source/lang combo)
Add Slack errors (Day 7)
Monitor: n8n Executions > Filter “Brevo”

Avoid These Traps:

Missing email validation → 400 errors
Sequential IFs → Lost multi-tags
No pre-created Brevo tags → Fail silently
Ignoring rate limits → 429 blocks
