# flask-mailjet

A lightweight, secure, and production-ready Flask extension for sending
emails through the **Mailjet API**, built on top of the official
`mailjet-rest` library.

------------------------------------------------------------------------

## 🚀 Features

-   Simple configuration via `MAILJET_API_KEY` and `MAILJET_API_SECRET`
-   Straightforward email sending (HTML, multiple recipients)
-   Built‑in support for file attachments
-   Templating helper for rendering email templates
-   Works with both eager app initialization and the Flask Factory
    pattern
-   Clean API fully aligned with Mailjet's expectations

------------------------------------------------------------------------

## 📦 Installation

``` bash
pip install flask-mailjet
```

------------------------------------------------------------------------

## 🛠️ Configuration

Add the following to your Flask application configuration:

``` python
app.config["MAILJET_API_KEY"] = "YOUR_API_KEY"
app.config["MAILJET_API_SECRET"] = "YOUR_API_SECRET"
```

  Variable               Description
  ---------------------- -----------------------------
  `MAILJET_API_KEY`      Your Mailjet API Public Key
  `MAILJET_API_SECRET`   Your Mailjet API Secret Key

------------------------------------------------------------------------

## 🔧 Initialization

### **Option 1: Eager Initialization**

``` python
from flask import Flask
from flask_mailjet import Mailjet

app = Flask(__name__)
app.config["MAILJET_API_KEY"] = "YOUR_API_KEY"
app.config["MAILJET_API_SECRET"] = "YOUR_API_SECRET"

mailjet = Mailjet(app)
```

### **Option 2: Factory Pattern**

``` python
from flask_mailjet import Mailjet

mailjet = Mailjet()

def create_app():
    app = Flask(__name__)
    app.config.from_mapping(
        MAILJET_API_KEY="YOUR_API_KEY",
        MAILJET_API_SECRET="YOUR_API_SECRET",
    )

    mailjet.init_app(app)
    return app
```

------------------------------------------------------------------------

## ✉️ Sending Emails

All mail‑sending methods expect the **sender** field as:

``` python
{"Email": "sender@example.com", "Name": "Sender Name"}
```

------------------------------------------------------------------------

### **1. send_email --- Basic HTML Email**

``` python
from_user = {"Email": "alerts@app.com", "Name": "App Alerts"}
to_user = ["user1@mail.com", "user2@mail.com"]

mailjet.send_email(
    sender=from_user,
    recipients=to_user,
    subject="Your Account Is Active",
    html="<h1>Welcome!</h1><p>Your subscription is confirmed.</p>"
)
```

------------------------------------------------------------------------

### **2. send_email_with_attachment --- Email + File Attachment**

``` python
import os

pdf_path = os.path.join(app.root_path, "static", "invoice.pdf")
with open(pdf_path, "rb") as f:
    pdf_bytes = f.read()

mailjet.send_email_with_attachment(
    sender={"Email": "billing@app.com"},
    recipients="client@corp.com",
    subject="Q4 Financial Report",
    html="<p>Attached is the report.</p>",
    filename="Q4_Report.pdf",
    file_bytes=pdf_bytes,
    content_type="application/pdf",
)
```

------------------------------------------------------------------------

## 🎨 Template Rendering (loader.py)

You can render email templates stored in:

    flask_mailjet/templates/mailjet/

### **Example**

``` python
from flask_mailjet.loader import render_email_template

email_html = render_email_template(
    "welcome.html",
    user_name="Tim",
    link="https://app.example.com"
)

mailjet.send_email(
    sender={"Email": "system@app.com"},
    recipients="user@app.com",
    subject="Welcome!",
    html=email_html,
)
```

------------------------------------------------------------------------

## 📁 Project Structure Example

    yourapp/
    ├── app.py
    ├── templates/
    │   └── mailjet/
    │       └── welcome.html
    └── extensions/
        └── mailjet.py

------------------------------------------------------------------------

## 🧪 Testing

You can mock Mailjet easily using Python's builtin tools:

``` python
from unittest.mock import patch

@patch("flask_mailjet.Mailjet.send_email")
def test_send(mock_send):
    mock_send.return_value = {"Status": "success"}
```
