This Python package offers integration with the official API for Mailtrap.
Add email sending functionality to your Python application quickly with Mailtrap.
Versions of this package up to 1.0.1 were different, unrelated project, that is now maintained as Sendria. To continue using it, see instructions.
- Python version 3.9+
pip install mailtrap
import mailtrap as mt
API_TOKEN = "<YOUR_API_TOKEN>" # your API key here https://mailtrap.io/api-tokens
client = mt.MailtrapClient(token=API_TOKEN)
# Create mail object
mail = mt.Mail(
sender=mt.Address(email="sender@example.com", name="John Smith"),
to=[mt.Address(email="recipient@example.com")],
subject="You are awesome!",
text="Congrats for sending test email with Mailtrap!",
)
client.send(mail)Mailtrap lets you test safely in the Email Sandbox and then switch to Production (Sending). Remove the inbox_id field or set it to None. Then, remove the sandbox field or set it to False. You can change the arguments in the code or via another way. Here is an example using environment variables.
Set next environment variables:
MAILTRAP_API_KEY=your_api_token # https://mailtrap.io/api-tokens
MAILTRAP_USE_SANDBOX=true # true/false toggle
MAILTRAP_INBOX_ID=123456 # Only needed for sandboxBootstrap logic:
import os
import mailtrap as mt
API_KEY = os.environ["MAILTRAP_API_KEY"]
IS_SANDBOX = os.environ.get("MAILTRAP_USE_SANDBOX", "true").lower() == "true"
INBOX_ID = os.environ.get("MAILTRAP_INBOX_ID")
client = mt.MailtrapClient(
token=API_KEY,
sandbox=IS_SANDBOX,
inbox_id=INBOX_ID, # None is ignored for production
)
# Create mail object
mail = mt.Mail(
sender=mt.Address(email="sender@example.com", name="John Smith"),
to=[mt.Address(email="recipient@example.com")],
subject="You are awesome!",
text="Congrats for sending test email with Mailtrap!",
)
client.send(mail)Bulk stream example (optional) differs only by setting bulk=True:
bulk_client = mt.MailtrapClient(token=API_KEY, bulk=True)
Recommendations:
- Use separate API tokens for Production and Sandbox.
- Keep initialisation in a single factory object/service so that switching is centralised.

client.send(mail)import os
import mailtrap as mt

template_variables={"user_name": "John Doe"},
)
client.send(mail)This approach is newer. It can be useful when you expect the response to be model-based rather than dictionary-based, as in MailtrapClient.send().
import os
import mailtrap as mt
client = mt.MailtrapClient(token=os.environ["MAILTRAP_API_KEY"])
sending_api = client.sending_api
# create mail object
mail = mt.Mail(
sender=mt.Address(email="sender@example.com", name="John Smith"),
to=[mt.Address(email="recipient@example.com")],
subject="You are awesome!",
text="Congrats for sending test email with Mailtrap!",
)
sending_api.send(mail)Response:
{
"success": True,
"message_ids": ["5162954175"]
}Response:
SendingMailResponse(success=True, message_ids=["5162955057"])The same situation applies to both client.batch_send() and client.sending_api.batch_send().

git clone https://github.com/mailtrap/mailtrap-python.git
cd mailtrap-pythonInstall 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 --helpTo setup virtual environments, run tests and linters use:
toxIt will create virtual environments with all installed dependencies for each available python interpreter (starting from python3.9) 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/activateIf 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"The project is available as open source under the terms of the MIT License.
Everyone interacting in the Mailtrap project's codebases, issue trackers, chat rooms and mailing lists is expected to follow the code of conduct
