Prerequisites

To get the most out of this guide, you’ll need to:

​
1. Setup your environment

Create and activate your new virtualenv.

virtualenv venv
source venv/bin/activate

Install dependencies.

pip install -r requirements.txt

Set your RESEND_API_KEY environment variable by running.

export RESEND_API_KEY="re_123456789"

​
2. Send email using Django’s SMTP EmailMessage

Set the necessary attributes in your settings.py file.

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
RESEND_SMTP_PORT = 587
RESEND_SMTP_USERNAME = 'resend'
RESEND_SMTP_HOST = 'smtp.resend.com'

Use Django’s get_connection and EmailMessage

import os
from django.conf import settings
from django.http import JsonResponse
from django.core.mail import EmailMessage, get_connection

# Sample Django view
def index(request):

    subject = "Hello from Django SMTP"
    recipient_list = ["delivered@resend.dev"]
    from_email = "onboarding@resend.dev"
    message = "<strong>it works!</strong>"

    with get_connection(
        host=settings.RESEND_SMTP_HOST,
        port=settings.RESEND_SMTP_PORT,
        username=settings.RESEND_SMTP_USERNAME,
        password=os.environ["RESEND_API_KEY"],
        use_tls=True,
        ) as connection:
            r = EmailMessage(
                  subject=subject,
                  body=message,
                  to=recipient_list,
                  from_email=from_email,
                  connection=connection).send()
    return JsonResponse({"status": "ok"})

​
3. Try it yourself
