Integrate n8n with Email Tools

Prerequisites

• n8n instance running
• Email tool account (Instantly, Smartlead, or Loops) with API access

Steps

1. Set up email tool credentials. In n8n, create a new credential for your email tool. For Instantly: use API key from Settings > Integrations. For Loops: use the API key from Settings > API. Store credentials securely in n8n's credential manager.

2. Automate lead-to-campaign flow. Build a workflow: Trigger (new enriched lead from Clay or CRM) > IF node (filter by lead score > 60) > HTTP Request node (add lead to Instantly campaign via API). This automatically enrolls qualified leads in your outbound sequence.

3. Route replies to CRM. Build a workflow: Trigger (Instantly webhook on reply received) > Code node (classify reply as positive/negative using keywords or AI) > IF node (branch on classification) > Attio node (create deal for positive replies). This ensures no interested reply falls through the cracks.

4. Trigger lifecycle emails from events. Build a workflow: Trigger (product event webhook) > Set node (map user data to Loops contact properties) > HTTP Request (update Loops contact or trigger transactional email). Use this for onboarding events, feature adoption signals, and usage milestones.

5. Sync unsubscribes across tools. Build a workflow: Trigger (unsubscribe event from any email tool) > HTTP Request (add to suppression list in all other email tools) > Attio node (update contact property "email_opt_out" = true). This keeps you compliant across all platforms.

6. Monitor email health. Build a scheduled workflow that runs daily, pulls campaign metrics from your email tool via API, and posts a summary to Slack: emails sent, replies received, bounces, and any accounts with deliverability issues.
