Typsicherer Python-Client für email-validaton.com. Synchron + asynchron, Pandas-kompatibel.

Installation

pip install email-validator-client

# With async (httpx):
pip install email-validator-client[async]

# With Pandas:
pip install email-validator-client[pandas]

# Everything:
pip install email-validator-client[all]

Voraussetzungen: Python 3.10+, pydantic>=2.0, requests>=2.28.

Schnellstart

from email_validator_client import Client

client = Client('ev_your_api_key')

result = client.verify('user@gmail.com')

if result.is_valid:
    print(f'Valid — confidence: {result.confidence}')
elif result.is_disposable:
    print('Disposable email — reject!')
elif result.is_catch_all:
    print('Catch-all — caution')

Asynchron (httpx)

import asyncio
from email_validator_client import Client

async def main():
    client = Client('ev_...')

    result = await client.verify_async('user@gmail.com')
    print(result.status)

    # Bulk async with concurrency control
    emails = ['a@b.com', 'c@d.com', 'e@f.com']
    results = await client.verify_bulk_async(emails, concurrency=10)

asyncio.run(main())

Pandas-Integration

import pandas as pd
from email_validator_client import Client
from email_validator_client.pandas import verify_dataframe

client = Client('ev_...')

# Load CSV, verify emails, export
df = pd.read_csv('subscribers.csv')
enriched = verify_dataframe(client, df, email_column='email')
enriched.to_csv('verified.csv', index=False)

# Filter deliverable only
deliverable = enriched[enriched['is_deliverable']]
