Installation

pip install email_deliverability

Quick Start

from email_deliverability import DeliverabilityManager

# Initialize the manager with your domain and IP
manager = DeliverabilityManager(domain="example.com", ip="8.8.8.8")

# Analyze authentication setup
auth_results = manager.analyze_domain_setup()
print(f"Authentication Score: {auth_results['overall_score']}/100")

# Check IP reputation
ip_results = manager.check_ip_reputation()
if ip_results['status'] == 'clean':
    print("IP is not listed on any blacklists")
else:
    print(f"IP is listed on {len(ip_results['blacklisted_on'])} blacklists")

# Validate email addresses
emails = ["user@example.com", "invalid@nonexistent.domain", "test@mailinator.com"]
validation_results = manager.validate_email_list(emails)
print(f"List Quality: {validation_results['analysis']['quality_level']}")

# Create an IP warming plan
warming_plan = manager.create_ip_warming_plan(daily_target=10000, warmup_days=30)
print(f"Warming schedule created for {warming_plan['warmup_days']} days")

# Get comprehensive deliverability status
status = manager.check_deliverability_status()
for recommendation in status['recommendations']:
    print(f"- {recommendation}")
