This Acceptable Use Policy ("AUP") governs how you may use Email Verifier by EcomTech's email verification services, website, and API. By using our services, you agree to comply with this policy. Violations may result in suspension or termination of your account. This AUP is part of and supplements our Terms of Service.

1. Permitted Uses

Our email verification services are designed for the following legitimate purposes:

• Email list cleaning: Verifying existing email lists to remove invalid, inactive, and undeliverable addresses before sending marketing campaigns or transactional emails
• Real-time signup validation: Integrating our API into registration forms, checkout pages, and lead capture forms to validate email addresses at the point of collection
• CRM and database hygiene: Periodically verifying email addresses stored in your CRM, marketing automation platform, or customer database to maintain data accuracy
• Compliance support: Using verification results to support compliance with email marketing regulations such as CAN-SPAM, GDPR, CASL, and other applicable laws
• Deliverability improvement: Identifying and removing high-risk addresses (bounces, spam traps, disposable emails) to improve your email deliverability rates and sender reputation
• Domain and authentication checks: Verifying domain configurations, MX records, SPF, DKIM, and DMARC records for domains you own or are authorized to manage
• Application integration: Building applications and workflows that use our API for email validation as part of a broader service, in compliance with our API terms

2.2 Malicious and Illegal Activities

• Attempting to identify, locate, or track individuals using email verification results
• Using verification results to discriminate against individuals based on their email provider, domain, or any protected characteristic

2.3 Service Abuse

• Using automated tools, bots, or scripts to access our website or API in a manner that exceeds normal usage patterns or is designed to circumvent our systems
• Reverse engineering, decompiling, or attempting to extract the source code of our verification engine or algorithms

3. API-Specific Rules

In addition to the general rules above, API users must adhere to the following:

• Respect rate limits as documented in our API documentation. Default limits are 10 requests per second for standard plans and higher for enterprise plans
• Implement appropriate error handling and retry logic with exponential backoff — do not hammer our endpoints on failure
• Cache verification results locally when appropriate to minimize redundant API calls for the same address
• Keep API keys secure and rotate them if you suspect unauthorized access
• Include proper User-Agent headers in API requests for identification purposes
• Do not use our API to perform competitive benchmarking or accuracy testing of our service without prior written consent
