Prerequisites

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

​
1. Install

Get the Resend Python SDK.

pip install resend

​
2. Send email using HTML

The easiest way to send an email is by using the html parameter.

index.py
import resend
import os
from flask import Flask, jsonify

resend.api_key = os.environ["RESEND_API_KEY"]

app = Flask(__name__)


@app.route("/")
def index():
    params = {
        "from": "Acme <onboarding@resend.dev>",
        "to": ["delivered@resend.dev"],
        "subject": "hello world",
        "html": "<strong>it works!</strong>",
    }

    r = resend.Emails.send(params)
    return jsonify(r)


if __name__ == "__main__":
    app.run()

​
3. Try it yourself
