Zapier Integration

Zapier is the leading workflow automation platform. You can integrate Reloop with Zapier in two ways to send emails when triggers happen in other apps (like CRM updates, new form responses, or database inserts):

1. SMTP Integration (using Zapier's built-in SMTP by Zapier action)
2. API Integration (using Zapier's built-in Webhooks by Zapier action)

Method 1: SMTP by Zapier

This is the easiest way to send plain text or HTML emails from any app trigger without writing API payloads.

Step 1: Add a Trigger

Create a new Zap and configure the trigger app (e.g., Google Sheets, Typeform, Stripe).

Step 2: Add the "SMTP by Zapier" Action

1. Search for and select SMTP by Zapier as your action step.
2. Select Send Email as the Event and click Continue.

Step 3: Connect Reloop SMTP

In the Choose Account tab, set up the SMTP server configuration:

Step 4: Configure Email Fields

Set up the message template by mapping dynamic fields from your trigger step:

• From Email: Enter a verified email address from your Reloop sending domain (e.g., notification@yourdomain.com).
• To: Select the recipient's email address from your trigger.
• Subject: Enter the subject line (you can mix static text and dynamic fields).
• Body (HTML or Text): Enter the body of the email. Set Format to html if you want to send styled content.

Method 2: Webhooks by Zapier (REST API)

Use this method if you need advanced features like email tagging, custom headers, scheduling emails to send later, or attachments.

Step 1: Add a Trigger

Set up your Zap's trigger step.

Step 2: Add Webhooks by Zapier

1. Add a new action step and select Webhooks by Zapier.
2. Select Custom Request or POST as the Event and click Continue.

Step 3: Configure the API Request

Fill out the API endpoint details exactly as follows:

• Method: POST
• URL: https://reloop.sh/api/mail/v1/send
• Data (Payload): Define your email parameters in JSON format. For example:

{
  "from": "Your Company <hello@yourdomain.com>",
  "to": "recipient@example.com",
  "subject": "Hello from Zapier Webhook!",
  "html": "<p>Hi {{first_name}}, this email was sent automatically.</p>",
  "tags": [
    {
      "name": "source",
      "value": "zapier"
    }
  ]
}

Note: Replace {{first_name}} and recipient@example.com with dynamic values from your Zap trigger.

• Headers: Add the following headers for authorization:
