Flask email

Send Flask email with an API or SMTP

Flask apps usually need a few reliable email flows: verify an account, reset a password, notify support, or send a receipt. zaSend works from Flask through the Python SDK or standard SMTP.

Python SDK example

from zasend import ZaSend

client = ZaSend(app.config["ZASEND_API_KEY"])

def send_welcome_email(user):
    client.send_email(
        from_email="Acme <noreply@yourdomain.com>",
        to=user.email,
        subject="Welcome to Acme",
        text="Thanks for creating an account.",
        html="<p>Thanks for creating an account.</p>",
    )

Do not send from the browser

Keep API keys and SMTP keys on the server. If your Flask app has a frontend, send a request to your own backend first, then let the backend call zaSend.
