mail7 (Python)

Official Mail7 email validation client. Zero dependencies (stdlib only).

pip install mail7

from mail7 import Mail7

client = Mail7(api_key="...")   # api_key optional (free anonymous tier without it)

result = client.validate("user@example.com")
print(result["status"])         # "Valid" | "Not Valid" | "Unknown"
print(result["valid"])          # True | False | None (None when Unknown)
print(result["is_disposable"])  # True for throwaway addresses

Honest classification

status is Valid, Not Valid, or Unknown. valid is None when the address could not be verified (catch-all, greylisting, disposable) - so you never wrongly reject a real person. Branch on status; do not treat Unknown as invalid.

API

• Mail7(api_key=None, base_url="https://mail7.net/api", timeout=20)
• validate(email) -> dict
• raises Mail7Error on API/transport errors.
