Unlike the standard library's synchronous smtplib, it integrates directly into async/await code, making it suitable for applications that handle many concurrent operations\u2014web servers, task queues, or any asyncio-based system that needs to send mail.\n\nThe package has no runtime dependencies and installs as a single wheel. It wraps the SMTP protocol in async methods, so you construct an EmailMessage using the standard library's email.message module, then pass it to aiosmtplib.send() or manage a connection manually. Requires Python 3.10 or later.","worth_installing":"Yes. aiosmtplib is actively maintained, has no dependencies, carries a permissive MIT license, and fills a clear gap for async Python applications that need SMTP. The low install friction and stable production status make it a straightforward choice if you're already using asyncio and need to send email without blocking."},"id":"aiosmtplib","links":{"html":"https://skillfed.io/packages/aiosmtplib","md":"https://skillfed.io/packages/aiosmtplib.md","pypi":"https://pypi.org/project/aiosmtplib/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-06-20","license_spdx":null,"license_treatment":"permissive","name":"aiosmtplib","python_support":"supports_current","summary":"asyncio SMTP client"},"popularity":{"monthly_downloads":19588512,"position":1059,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"5.1.2"}
