Unofficial Async fork of the official Mailtrap Python client

Adds async support to the official Mailtrap Python client. This fork is not maintained by the original authors of the official Mailtrap Python client.

This Python package offers integration with the official API for Mailtrap.

Quickly add email sending functionality to your Python application with Mailtrap.

Compatibility with previous releases

The fork requires Python 3.10 and uses httpx rather than requests.

The non-async version of the official Mailtrap Python client is available at mailtrap.

This version maintains the same API as the official Mailtrap Python client, with the addition of an async send method, it is called using await client.asend.

I have versioned this as 3.0.0 due to the breaking changes in the dependencies.

Original compatilibility message

Versions of this package up to 1.0.1 were a different, unrelated project, that is now maintained as Sendria. To continue using it, see instructions.

Development Environment

Clone the repo

https://github.com/railsware/mailtrap-python.git
cd mailtrap-python

Install tox

tox is an environment orchestrator. We use it to setup local environments, run tests and execute linters.

python -m pip install --user tox
python -m tox --help

To setup virtual environments, run tests and linters use:

tox

It will create virtual environments with all installed dependencies for each available python interpreter (starting from python3.6) on your machine. By default, they will be available in {project}/.tox/ directory. So, for instance, to activate python3.11 environment, run the following:

source .tox/py311/bin/activate

Information for version 1 users

If you are a version 1 user, it is advised that you upgrade to Sendria, which is the same package, but under a new name, and with new features. However, you can also continue using the last v1 release by locking the version in pip:

# To use the FORMER version of the mailtrap package, now known as Sendria:
pip install --force-reinstall -v "mailtrap==1.0.1"
