Question 1

How do I send bulk emails with fastapi-mail?

Accepted Answer

Pass a list of recipient emails to the MessageSchema recipients field; the library handles individual sends, but you must manage batching and rate limits externally, as shown in the bulk examples in the documentation.

Question 2

Fastapi-mail vs SendGrid – which is better for FastAPI?

Accepted Answer

Fastapi-mail is ideal for self-hosted SMTP sending with full control and no third-party costs, while SendGrid offers more features like analytics and deliverability tools but requires API integration and potential fees. Choose based on your need for control versus convenience.

Question 3

Can I attach files from a user upload form using fastapi-mail?

Accepted Answer

Yes, extract files from form-data in your endpoint and pass them to the MessageSchema; the library handles MIME types, but ensure your FastAPI setup correctly processes multipart form data.

Question 4

Does fastapi-mail support SSL/TLS for secure email sending?

Accepted Answer

Yes, configure MAIL_SSL_TLS or MAIL_STARTTLS in ConnectionConfig to enable encryption; it uses standard Python SMTP libraries, supporting common security protocols like TLS for secure transmissions.

Question 5

How to use Jinja2 templates with variables in fastapi-mail?

Accepted Answer

Load a Jinja2 template file, render it with context variables, and pass the HTML string to the MessageSchema body; the examples in the documentation show basic usage, but complex templates may require additional Jinja2 setup.

Question 6

Is fastapi-mail suitable for high-traffic production apps?

Accepted Answer

It's lightweight and async, making it scalable, but for very high volumes, you'll need to implement additional queuing or rate limiting; the background task integration helps, but performance should be monitored under load.
