Introduction
This guide demonstrates how to send a basic email using the Resend API. You’ll learn how to set up your environment, configure your API key, and send an email.
Setup
Step 1: Install Required Packages
First, install the necessary packages using pip:
pip install python-dotenv resend
Step 2: Create a .env File
Create a .env
file in the project root with your Resend API key and email details:
RESEND_API_KEY=your_resend_api_key
RESEND_EMAIL_FROM=your_email_from_address
RESEND_EMAIL_TO=recipient_email_address
Sending an Email
Step 3: Create the Python Script
Create a Python script named resend-email-example.py
with the following content:
import os
from dotenv import load_dotenv
import resend
# Load environment variables from .env file
load_dotenv()
# Get API key and email details from environment variables
resend.api_key = os.getenv('RESEND_API_KEY')
email_from = os.getenv('RESEND_EMAIL_FROM')
email_to = os.getenv('RESEND_EMAIL_TO')
# Define email content
subject = "Hello World"
email_body = "<strong>It works!</strong>"
try:
# Send the email using Resend API
response = resend.Emails.send({
"from": email_from,
"to": email_to,
"subject": subject,
"html": email_body
})
# Print and return the response
print(f"Email sent to {email_to}. Response: {response}")
response
except Exception as e:
# Print and return the error message
print(f"Failed to send email. Error: {e}")
{"status": "error", "message": str(e)}
Step 4: Run the Script
Ensure you have the .env
file in the same directory as the script. Then, execute the script:
python resend-email-example.py
