Connect Sendzovo to the Tools You Already Use

Add transactional email to your application through APIs, SMTP, webhooks and email verification without rebuilding your existing application architecture.

One Email Platform, Multiple Ways to Integrate

Choose the integration method that best matches your application's architecture and existing email workflow.

Email API

Send email directly from your backend using HTTPS requests and the Sendzovo Email API.

Webhooks

Where supported, send email events back to your application so your systems can react to delivery activity.

Sendzovo → Event → Your Application

Email Verification

Verify addresses before sending and integrate email quality checks into your existing application workflows.

Integrate With Your Application Stack

Sendzovo uses standard HTTP and SMTP technologies, making it suitable for applications built with the languages and frameworks your team already knows.

PHP & Laravel

Connect Laravel applications using SMTP or direct HTTP requests to the Sendzovo API.

Node.js

Add transactional email to Node.js applications, APIs and backend services.

Python & Django

Integrate email into Python and Django applications using API or SMTP workflows.

.NET

Connect ASP.NET and other .NET applications using standard HTTP or SMTP capabilities.

Java

Integrate Java applications and backend services through the Sendzovo API or SMTP.

Any HTTP-Compatible Application

If your application can make HTTPS requests, it can integrate directly with the Sendzovo API.

Build Directly With the Email API

Use the Sendzovo API when you want your application to control email sending programmatically.

POST https://api.sendzovo.com/v1/emails

Authorization: Bearer em_live_xxxxxxxxx
Content-Type: application/json

{
  "from": "hello@example.com",
  "to": "customer@example.com",
  "subject": "Your order has shipped",
  "html": "<p>Your order is on its way.</p>"
}

HTTPS Requests

Use standard HTTPS requests to integrate email into your backend services.

JSON-Based Integration

Work with a familiar JSON request format from the language or framework of your choice.

Backend Integration

Keep API credentials and email operations inside your server-side application.

Application-Controlled Sending

Trigger transactional messages directly from application events and business logic.

Use SMTP With Existing Applications

If your application already uses SMTP, you can connect Sendzovo without redesigning your entire email architecture.

Standard SMTP Connection

Configure your existing mail system to connect to Sendzovo's SMTP service.

SMTP Host: smtp.sendzovo.com
Port: 587
Encryption: TLS

Existing Mail Libraries

Continue using the mail libraries and framework integrations already present in your application.

Application → SMTP → Sendzovo

Secure Your Integration

Keep your email infrastructure secure by protecting application credentials and authenticating the domain used for sending.

API Credentials

Keep API credentials on your backend and avoid exposing sensitive credentials in client-side code.

SMTP Credentials

Configure SMTP credentials in your application's secure environment configuration.

Domain Authentication

Configure the appropriate DNS authentication records for your sending domain.

HTTPS

API integrations use HTTPS to protect communication between your application and Sendzovo.

Combine Integrations With Email Templates

Keep your application logic separate from recurring transactional email content by using reusable templates where supported.

Add Verification Where Email Quality Matters

Email verification can become part of the same application workflow that collects, stores and sends to email addresses.

Signup

Evaluate an email address before accepting it during account registration.

Signup → Verify → Account

Lead Collection

Check addresses collected through forms and lead generation workflows.

Lead → Verify → Store

List Cleaning

Evaluate existing recipient lists before they enter an email sending workflow.

List → Verify → Clean

Pre-Send Verification

Add verification to workflows where recipient address quality needs to be evaluated before sending.

Verify → Evaluate → Send

Connect Email Events Back to Your Application

Where webhook functionality is enabled, connect supported Sendzovo email events to the systems that already manage your application data and workflows.

Delivery Updates

Receive supported delivery events and update application state when message status changes.

Automated Workflows

Connect email events to internal processes, notifications and application workflows.

Common Integration Patterns

Choose an architecture based on how your application currently handles email.

API-First

Best for applications where your backend directly controls transactional email.

App → API → Sendzovo

SMTP-Based

Best for applications that already use SMTP-compatible mail libraries and frameworks.

App → SMTP → Sendzovo

Verified Sending

Add email verification before sending important application messages.

Verify → Send → Deliver

Event-Driven

Connect supported email events back into your application's workflows.

Send → Event → Webhook → App

Moving an Existing Application to Sendzovo?

You don't necessarily need to redesign your application. Choose the integration path that matches your current email infrastructure.

Already Using SMTP?

Update your SMTP host, port, credentials and security settings to connect your existing mail workflow to Sendzovo.

Building a New Application?

Use the Email API to build email sending directly into your application's backend.

Cleaning an Existing List?

Add email verification before moving recipient data into your sending workflow.

Need Event-Based Workflows?

Where supported, connect email events to your application's webhook endpoints.
