django-anymail VS flanker

I would strongly suggest that you take a look at the django-anymail package. Using it will allow you to be able to swap between ESPs (if you are no longer please by their services) without having to refactor your code (switching packages/sdk). It has been a big time saver in a project of mine and the maintainer of the package responds quickly to any issues or questions you might have.

Once you switch to a transactional email service provider like mailgun, sendgrid or SES (as others have suggested), also take a look at the django anymail project: https://anymail.dev/ for a super seamless integration.

Popular answers include DRF, django-extensions, anymail, allauth and the DJDT.

I use django-anymail as the email backend. It hooks into Django and allows you to easily swap in and swap out different email providers. That way you're provider agnostic and can avoid vendor lock-in. Did Sendgrid hike their prices? Change three lines of code and use Amazon SES.

So, it's time to switch to the Mail Service provider. In our case it will be Mailgun. To do this, you just need to register and attach the card to your Mailgun account. After activating your account with the card attached, you can set up a domain for your email.

This guide will describe how to set up Uptime Kuma on Koyeb to monitor your services and send notifications. Uptime Kuma uses a local SQLite database to store user data, configuration for services, and more. We will deploy it alongside Litestream to automatically replicate the data to an S3-compatible bucket hosted on Backblaze's B2 service. We'll use a Mailgun account to set up SMTP details for notifications.

Sendgrid, Mailgun, or Postmark are great solutions if you have a need for transactional emails that are technical. I still prefer using Customer.io for this need. If you’re unsure what transactional emails are, check out this guide.

Anyway, in answer to your question, you most likely can’t. You should use a mail relay service such as MailGun. https://www.mailgun.com/

You could consider to use some email delivery service like Mailgun or Sendgrid. They offer free tiers and their servers are more accepted than some random self-hosted server.

Visit the Mailgun website and sign up for an account. To create your account, provide the required information, including your email address and password. Mailgun offers different plans, including a free tier with limited features.
