pymissive
Lightweight, framework-agnostic Python library for multi-channel message sending: email, SMS, WhatsApp, registered electronic mail (LRE) and team messaging.
Overview
pymissive exposes one provider interface per channel, so the calling code stays the same whichever service actually delivers the message. It is the base of django-pymissive and can be used on its own in any Python project.
The PyPI name is pymissive; the directory holding it in this monorepo is
python-pymissive/.
Main features
- 🔌 8 providers, all sharing the same service names
- 📧 Email: Brevo, Scaleway
- 📱 SMS: Brevo, SMSPartner
- 💬 WhatsApp: Brevo
- 📮 Registered electronic mail (LRE): Maileva
- 👥 Team messaging: Slack, Microsoft Teams, Discord
- ✋ Hand delivery: tracks an in-person hand-over, no external API
- 🏗️ Modular architecture based on ProviderKit
- ✅ Framework-agnostic: usable with or without a framework
- 🎯 Type hints throughout
Installation
pip install pymissive
requests is a base dependency, so Maileva and SMSPartner work as installed.
Providers needing another SDK have their own extra. Those imports are lazy, so a
missing extra only disables that one provider:
pip install pymissive[brevo] # brevo-python
pip install pymissive[scaleway] # boto3
pip install pymissive[discord] # discord.py
Quick usage
from pymissive.providers.slack import SlackProvider
provider = SlackProvider(config={
"SLACK_BOT_TOKEN": "xoxb-your-token",
"SLACK_CHANNEL_ID": "C0123456789",
})
result = provider.send_branded(
subject="Deployment finished",
body_text="Version 1.3.15 is live.",
)
Each key in config_keys is read from config first, then from the
environment, so exporting SLACK_BOT_TOKEN instead works the same way.
Available providers
Services are named <verb>_<missive_type> — send_email, retrieve_lre,
handle_webhook_sms, and so on. branded is the missive type used by the team
messaging platforms, where the sender identity is the bot rather than an address.

providers/todo/ holds one-class placeholders (SendGrid, Mailgun, Twilio,
Telegram, FCM, APN, SMTP, …). They are a backlog, not an API: they are not
importable and nothing is wired to them.
Architecture
Providers are plain classes discovered by ProviderKit:
from pathlib import Path
import pymissive.providers as providers_package
from providerkit import autodiscover_providers
classes = autodiscover_providers(
Path(list(providers_package.__path__)[0]),
base_module="pymissive.providers",
exclude_files=["base"],
)
# {'brevo': BrevoAPIProvider, 'maileva': MailevaProvider, ...}
Beware of ProviderBase.services: it lists the whole catalogue of service names,
not the subset a given provider implements. To know whether a provider really
supports something, look for the method itself:
provider = classes["brevo"]()
can_send_sms = hasattr(provider, "send_sms")

Development
pip install -e .
# Lint (same command as CI, from the repository root)
ruff check src
This package has no test suite of its own yet: CI only checks that it imports.
The behaviour of the providers is covered by the suite in django-pymissive/.
