Output:

{
  "recipientEmail": "contact@example.com",
  "subject": "Email Subject",
  "body": "<div>Email content</div>",
  "gmailBodyHtml": "<div>Email content</div><br><img tracking />",
  "trackingId": "uuid"
}

2. Start Sequence

Records the sent email in InboxPlus and starts automated follow-up sequence.

Parameters:

• Sender Email
• Recipient Email
• Subject (from Prepare Email)
• Thread ID (from Gmail)
• Message ID (from Gmail)
• Tracking ID (from Prepare Email)
• Sequence (dropdown - loads from your InboxPlus account)

Workflow Example

[Trigger]
    ↓
[InboxPlus: Prepare Email]
  - Recipient: contact@example.com
  - Template: "Welcome Email"
    ↓
[Gmail: Send Message]
  - To: {{ $json.recipientEmail }}
  - Subject: {{ $json.subject }}
  - Body HTML: {{ $json.gmailBodyHtml }}
    ↓
[InboxPlus: Start Sequence]
  - Sender: you@example.com
  - Recipient: {{ $("InboxPlus").item.json.recipientEmail }}
  - Subject: {{ $("InboxPlus").item.json.subject }}
  - Thread ID: {{ $("Gmail").item.json.threadId }}
  - Message ID: {{ $("Gmail").item.json.id }}
  - Tracking ID: {{ $("InboxPlus").item.json.trackingId }}
  - Sequence: "Onboarding Sequence"

How It Works

1. Prepare Email - Fetches template from InboxPlus and generates tracking pixel
2. Gmail - Sends the email (Day 0) with template content and tracking
3. Start Sequence - Records email in InboxPlus and starts automated follow-ups

InboxPlus then:

• Monitors the email thread for replies
• Sends Day 1, Day 2, etc. follow-ups automatically
• Stops sequence if recipient replies
• Tracks opens and clicks

Field Mapping

From Prepare Email to Gmail:

• recipientEmail → Gmail "To"
• subject → Gmail "Subject"
• gmailBodyHtml → Gmail "Body HTML"

From Prepare Email to Start Sequence:

• recipientEmail → "Recipient Email"
• subject → "Subject"
• trackingId → "Tracking ID"

From Gmail to Start Sequence:

• threadId → "Thread ID"
• id → "Message ID"

Important Notes

• Gmail is required - InboxPlus works WITH Gmail, not as a replacement
• Day 0 sent by Gmail - The first email is sent via Gmail node
• Follow-ups by InboxPlus - Automated follow-ups are sent by InboxPlus
• Tracking included - Tracking pixel is automatically added to emails
• Reply detection - InboxPlus monitors for replies and stops sequences

API Endpoints Used

• POST /user-emails/n8n/get-email-templates - Load templates
• POST /user-emails/n8n/get-sequences - Load sequences
• POST /user-emails/n8n/tracking-id - Generate tracking
• POST /user-emails/n8n - Record email and start sequence

Troubleshooting

Templates not loading

• Check API key is correct
• Verify templates exist in InboxPlus dashboard

Sequence not starting

• Ensure all fields are mapped correctly
• Check API response in node output
• Verify sequence exists and is active

Follow-ups not sending

• Wait for the configured delay (e.g., 24 hours for Day 1)
• Check sequence is active in InboxPlus dashboard
• Verify Gmail is connected in InboxPlus settings
