Zapier vs Make vs n8n: Intake → CRM → Slack → Sheets Automation for Small Teams (Step by Step)

Por

Automation is the closest thing to a superpower a small team can buy. Done right, it removes manual retyping, pings the right people automatically, and creates a reliable system of record without building an app. Three platforms dominate this space for SMBs and creators: Zapier, Make (formerly Integromat), and n8n. In this deep guide, you’ll learn when to use each one and you’ll build an end-to-end flow: a lead comes in from a form, gets enriched, lands in the CRM, alerts Slack with context, and logs to Google Sheets for analytics—complete with error handling, branching, and maintenance practices.

What each platform does best

Zapier

  • Strengths: fastest to start, huge app catalog, friendly no-code UI, good for linear flows, powerful “Formatter/Paths/Code by Zapier” for light transforms.
  • Watchouts: priced per task, complex branching can get expensive and harder to visualize, limits on heavy data throughput.

Make

  • Strengths: visual canvas with routers for branching, iterators/aggregators for arrays, granular scheduling and error handling, affordable for high-volume scenarios.
  • Watchouts: slightly steeper learning curve; you’ll think in “bundles,” mapping, and operations.

n8n

  • Strengths: open-source, self-host or cloud, JavaScript everywhere, fine-grained control, excellent for privacy-sensitive or custom APIs.
  • Watchouts: you manage hosting/updates if self-hosted; fewer one-click connectors than Zapier/Make; more technical.

Rule of thumb: start with Zapier for simple, time-sensitive flows; pick Make when you need branching, arrays, or cost efficiency; choose n8n for custom logic, on-prem data, or when you want to own the infrastructure.

The reference automation you’ll build

Goal: Intake → Enrich → De-dupe → Create/Update CRM → Notify Slack → Log to Google Sheets → Handle errors.

Inputs and tools (swap with your stack as needed):

  • Form: Typeform or Google Forms
  • Enrichment: Clearbit-like HTTP API (or your internal endpoint)
  • CRM: HubSpot or Pipedrive
  • Alerting: Slack
  • Analytics log: Google Sheets
  • Optional: Cloud storage (Drive) for attachments

Key requirements:

  • Idempotency (avoid duplicate contacts/deals)
  • Branching (new lead vs existing)
  • PII hygiene (don’t spray emails into public logs)
  • Observability (know when runs fail)

We’ll outline the build on each platform so you can mirror it in your tool of choice.

Core concepts you’ll use (applies to all three)

  • Triggers start the flow (form submission, webhook, schedule).
  • Actions call apps/APIs (create contact, post message, append row).
  • Filters/IF decide whether to continue based on conditions.
  • Paths/Routers/Switch create branches.
  • Mappers map fields between steps with transforms (lowercase emails, parse names).
  • Error handlers catch failures and route them to an alert queue.
  • Secrets store API keys safely; never hard-code them in text fields.
  • Idempotency keys prevent duplicates: use the email as a unique key or the form’s submission ID.

Build it in Zapier (linear + paths)

  1. Trigger: Typeform “New Entry” (or Google Forms via Google Sheets trigger). Turn on “Send test” to pull sample data.
  2. Formatter:
    • Text → Lowercase email.
    • Utilities → Split Name into first/last if needed.
    • Date/Time → Normalize timestamps to ISO 8601.
  3. Lookup (De-dupe): HubSpot “Find Contact by Email” (create if not found = false). Save contactId if found.
  4. Paths:
    • Path A (New contact):
      • HubSpot “Create Contact” with mapped fields.
      • HubSpot “Create Deal” with pipeline/stage; relate to contact.
    • Path B (Existing contact):
      • HubSpot “Update Contact” (append sourcing fields).
      • Optional: “Find Deal” by contact; if none, create one.
  5. Enrichment (optional): “Webhooks by Zapier” → GET to your enrichment API with email domain; use returned industry/employee count to tag lead score.
  6. Slack Alert: “Send Channel Message” to #new-leads with a compact template: New lead: {{company}} — {{first_name}} {{last_name}} ({{email}}) Source: {{source}} | Score: {{score}} Link: {{crm_deal_url}} Turn on “Include a link to this Zap run” for debugging.
  7. Google Sheets Log: Append row with submissionID, email (masked), company, created_at, path_taken, status. Mask PII: store em***@***.com or a hash.
  8. Error handling:
    • Add a Catch Hook Zap (separate Zap) receiving errors from “Send Catch Hook” steps in your main Zap; forward to a private Slack #automation-alerts.
    • In critical steps (CRM calls), enable “Zapier Transfer retries” and set Time out sensibly.
  9. Testing & naming: Prefix your Zap “LEAD-INTAKE//Zapier//v1”. Use Zapier’s Versions; keep v1 stable after launch.
  10. Turn on and watch the Zap runs. Bookmark the Zap Task History filtered by “Errors”.

Pros: fastest build, easy Slack formatting, great for teams without ops engineers.
Cons: Paths can multiply tasks; complex branches may be costly.

Build it in Make (branching + arrays)

  1. Trigger module: Typeform “Watch Responses” (or Webhook module for a custom form).
  2. Tools → Text aggregator to normalize names; Set variable for email_lower.
  3. HubSpot:
    • “Search Contacts” by email. Make returns bundles (arrays).
  4. Router:
    • Route 1 (Found) → Update contact → Find/Create deal.
    • Route 2 (Not found) → Create contact → Create deal.
  5. HTTP module for enrichment: a GET request to your API. Use Error handling → “Resume” if 404, “Throw” otherwise. Map industry, employees to CRM properties.
  6. Slack: “Create a Message” with a JSON template; you can @mention a user ID dynamically based on territory.
  7. Google Sheets: “Add a Row” with masked email and run metadata (scenario ID, execution ID).
  8. Attachments (optional): If the form can include files, use Iterator on an array of file URLs → HTTP Get a File → Google Drive Upload a File; collect returned Drive links via Array aggregator and store them in the CRM notes field.
  9. Error handling and retries: Right-click a module → On error → “Break” to a custom Slack alert path with run data; enable Auto retries for transient 429/5xx responses; set Rate limit per connection if your CRM enforces quotas.
  10. Scheduling & ops: Turn on the scenario with Immediate scheduling for webhooks and Every 1 minute fallback for polling triggers. Name your scenario “LEAD-INTAKE//Make//v1”, add a Notes section summarizing inputs/outputs and owners.

Pros: superb visual branching, cheaper at volume, strong file/array handling.
Cons: the mental model (bundles, iterators) takes a day to click.

Build it in n8n (full control + self-host)

  1. Trigger: Webhook node. Point your form to POST /lead-intake. Save a secret token header and verify it in a Function node to block spoofed calls.
  2. Set node: normalize fields; email = $json.email.toLowerCase().
  3. HTTP Request (CRM): “Search contacts by email”.
  4. If node: condition items[0].json.total > 0.
    • True branch (exists): HTTP Request to update contact; HTTP Request to find/create deal.
    • False branch (new): create contact then deal.
  5. HTTP Request for enrichment; in a Function node, map missing fields safely: const e = $json || {}; return [{ json: { industry: e.industry || 'unknown', size: e.employees || 0 } }];
  6. Slack: Slack node with a Markdown message. Manage secrets with Credentials; never hard-code tokens.
  7. Google Sheets: Google Sheets node append row; compute email_hash = $json.email.sha256() to avoid storing PII.
  8. Error path: Wrap critical nodes in Try/Catch workflow: on catch, send a Slack alert and write to a separate “errors” sheet with requestId, node name, error message.
  9. Idempotency: Insert a Postgres/SQLite node (or n8n Data store) to store submissionId. Check before running; if present, Exit quietly (use a NoOp node).
  10. Deploy: If self-hosted, run behind HTTPS with a reverse proxy (Traefik/Nginx), enable n8n queue mode (Redis) for concurrency, and set environment variables for rate limit/backoff. If on n8n Cloud, configure Execution data pruning to keep storage lean.

Pros: owns your data, flexible, great for custom APIs and on-prem.
Cons: more setup/admin; you need someone comfortable with JS and hosting.

Data hygiene, idempotency, and privacy

  • Unique keys: Use a deterministic key like form_submission_id or email+timestamp. Before creating contacts, search first.
  • Idempotent writes: Prefer upsert endpoints (create or update) when available.
  • Mask PII in logs; store only hashes where possible.
  • Secrets management: Use each platform’s credential vault; rotate keys quarterly.
  • Attachments: Scan file MIME types and size; store in a governed drive, not in Sheets or Slack.
  • Rate limits: Add delaying/queues (Make’s “Sleep”, n8n “Wait”, Zapier’s “Delay After Queue”) to avoid 429s during import bursts.

Monitoring and observability

  • Slack #automation-alerts with three message types: failures, throttling, and schema mismatches (e.g., a form question was renamed).
  • Heartbeat: a scheduled run posts “Automation OK” once per day; absence signals downtime.
  • Sampling: log 1 in every 50 successes in detail to a sheet or database for spot checks.
  • Dashboards: a simple Looker/Databox/GDS pulling from Sheets can chart daily lead count, new vs existing, average enrichment score, and failure rate by step.

Pricing and limits (practical take)

  • Zapier: priced per task; brilliant for <10k tasks/month and teams that value speed. Heavy branching multiplies tasks; budget accordingly.
  • Make: priced per operations; generally cheaper for complex flows and attachments. Watch operation counts on iterators.
  • n8n: open-source; cloud plan or your infrastructure cost. Best when you want to own data/compliance or need custom logic at scale.

If your lead volume is spiky or large with arrays/files, Make typically wins on cost. If the flow is linear and time-critical, Zapier wins on simplicity. If data residency/compliance matters or you need deep logic, go n8n.

Maintenance playbook

  • Versioning: clone scenarios/Zaps/Workflows per change; suffix with //v2, keep v1 active until v2 soaks.
  • Naming: [DOMAIN]–[FLOW]–[PLATFORM]–vX (e.g., LEAD–INTAKE–MAKE–v2).
  • Docs: one Notion page per flow: trigger, steps, fields, owners, rate limits, rollback plan.
  • Test fixtures: keep JSON samples from your form for replay in dev.
  • Guardrails:
    • Max retries = 3 with exponential backoff.
    • Circuit breaker: if error rate > 10% in 15 minutes, pause the scenario and alert.
    • Quarantine queue: send bad payloads to a review sheet.
  • Change control: when marketing edits the form, require a test submission to staging before production.

Troubleshooting checklist

  • 400/422 errors: field mapping changed—compare payload to API docs; validate required fields.
  • 401/403: expired tokens or missing scopes—reconnect the app; check permissions.
  • 404 on enrichment: handle as non-fatal; default values.
  • Duplicates: ensure you search first; add a unique key property in the CRM if possible.
  • Slack not notifying: bot lacks channel permission—invite it to the channel and retry.
  • Sheets quota exceeded: batch rows (Make aggregator or n8n Google Sheets “Append in bulk”), or write to BigQuery/DB instead.

Choosing the right tool for you (decision matrix)

  • I want the quickest win and a clear UI → Zapier.
  • I need branching, arrays, and cost-efficient scale → Make.
  • I need custom code, privacy, or on-prem → n8n.

Start with one flow, reach steady state for two weeks, then layer new automations. The goal is fewer handoffs, fewer reminders, and a clean audit trail—without hiring a developer team.
