redmail
Email sending library
Decision gist · record as of 2026-08-14
Yes, if you need a simple email-sending abstraction and are comfortable with an abandoned package. The API is clean, the single dependency (jinja2) is stable, and there are no known vulnerabilities. Install it for prototypes, internal tools, or low-risk automation. Avoid it for production systems where you need active maintenance, security updates, or support for evolving email standards.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires an SMTP server (local or remote) to be configured and accessible; credentials and host/port must be provided to EmailSender.
- Installation is straightforward with a single dependency (jinja2) and low friction.
- However, the package is abandoned—last release was 1266 days ago—so no active maintenance or security updates are available.

- Real-world compatibility with current email providers' SMTP configurations and security requirements.
What it is and what it does
Redmail is a Python email-sending library that abstracts away the complexity of the standard library's smtplib and email.mime modules. Instead of manually constructing MIME objects and managing SMTP connections, you instantiate an EmailSender, configure it with a host and port, and call send() with subject, recipients, and body content. It supports attachments, Jinja2 templating for dynamic email bodies, embedded images, formatted HTML tables, and cc/bcc recipients.
The package is designed for developers who need to send emails programmatically without boilerplate. Its main dependency is jinja2, which powers template rendering. However, the project is no longer maintained—the last release was 1266 days ago—so it receives no updates, bug fixes, or security patches. It remains functional for basic email tasks but carries the risk of incompatibility with future Python or email provider changes.
Use it for
- Send templated notification emails from a web application using Jinja variables for personalization.
- Automate bulk email reports with embedded charts, tables, or attachments from a scheduled task.
- Build a contact form or user signup flow that sends confirmation emails with minimal boilerplate code.
- Generate and email PDF invoices or receipts with attachments to customers.
- Send alerts or logs via email with formatted HTML tables and embedded images.
