NoParam is a real-time email validation API launched in March 2025, designed for developers who need fast, accurate, and privacy-compliant email verification without the complexity of older enterprise platforms. With a Pro pricing tier of $1.38 per 1,000 validations and a zero-retention data policy, NoParam positions itself as both affordable and compliant by default — making it suitable for Nigerian developers building under NDPR data minimization requirements. The API validates emails in under 300 milliseconds and goes beyond basic format checking to detect disposable email services and role-based addresses — two common vectors for fake signups in Nigerian consumer apps. ## What the API Does NoParam performs the following validation steps on each submitted email address: 1. **Syntax check**: Validates that the email address follows correct formatting rules (valid characters, @ symbol, valid domain structure). 2. **Domain existence check**: Confirms the email domain is registered and has valid DNS records. 3. **MX record check**: Verifies the domain has mail exchange records configured to receive email — confirming the domain is set up for email delivery. 4. **Mailbox existence check**: Probes the mail server to confirm the specific mailbox exists, without sending an actual test email. 5. **Disposable email detection**: Identifies addresses from temporary email services (10minutemail, Guerrilla Mail, Mailinator, etc.) commonly used to bypass registration requirements. 6. **Role-based email detection**: Flags addresses like info@, admin@, support@, sales@ which are typically shared team inboxes rather than individual user addresses — poor targets for personalized marketing or one-to-one communications. Results are returned in under 300ms as a JSON object with the validation status and individual check outcomes. ## How Developers Use It Integration is a simple REST API call with your API key for authentication. The endpoint accepts an email address and returns a JSON validation result. No SDK is required, though client examples are available in the NoParam documentation at docs.noparam.com. Beyond direct API integration, NoParam provides: - **WordPress plugin**: Validates emails directly in WordPress forms, WooCommerce checkouts, and registration pages without writing API code. - **Mailchimp integration**: Connect NoParam to your Mailchimp account to validate emails as they are added to your marketing lists. - **HubSpot and Brevo integrations**: Announced as coming soon. ## Pricing & Fees - **Free tier**: Available for initial testing and low-volume use. No credit card required. - **Pro plan**: $1.38 per 1,000 email validations — one of the most competitive per-validation rates among active email validation APIs. - **Enterprise**: Custom pricing with priority processing and dedicated support for high-volume users. ## Authentication API key authentication. Keys are obtained from the NoParam dashboard after registration at noparam.com. ## Rate Limits NoParam returns results in under 300ms. Specific per-second rate limits are not publicly documented and vary by plan. Contact NoParam for high-throughput production requirements. ## Privacy & Compliance NoParam is designed with privacy as a core principle: **the service never stores submitted email addresses**. Data is processed for validation and discarded — not retained in any database for secondary use, marketing, or resale. This zero-retention policy makes NoParam compliant with GDPR (EU), CCPA (California), and PIPEDA (Canada) by design. For Nigerian deployments under NDPR (Nigeria Data Protection Regulation), which requires data minimization and appropriate safeguards for personal data, NoParam's zero-retention architecture reduces data liability risk compared to providers that retain validated email records. ## Challenges & Gotchas for Nigerian Developers 1. **New platform (March 2025)**: NoParam is a relatively young service. While the core product works, ecosystem maturity (support depth, documentation breadth, edge case coverage) is still developing. 2. **No spam trap detection**: NoParam does not identify spam trap addresses — a gap that matters for email marketers protecting sender reputation. Pair with ZeroBounce if spam trap detection is required. 3. **No bulk file upload**: NoParam processes emails individually via API — no drag-and-drop CSV bulk upload tool as offered by ZeroBounce or Mailgun Validate. 4. **USD billing**: NoParam charges in USD. Nigerian developers need a USD-capable payment method. 5. **Free tier limits**: Free tier volume limits are not explicitly published — test your usage patterns before committing to the Pro plan. ## Company Background NoParam is a newer entrant in the email validation market, launched in March 2025. The product emphasizes simplicity, speed, privacy compliance, and competitive pricing as its differentiators. The WordPress plugin and no-code integrations (Mailchimp, and upcoming HubSpot and Brevo) suggest the team is targeting both developers and non-technical business users. ## Frequently Asked Questions **Q: Does NoParam store the emails I validate?** A: No. NoParam explicitly states it never stores submitted email data. Processing happens in memory and data is discarded after validation. **Q: Is the Pro tier really $1.38 per 1,000 validations?** A: Yes. At $0.00138 per email, the Pro tier is among the most competitively priced email validation options available. **Q: Does NoParam have a WordPress plugin?** A: Yes. A NoParam WordPress plugin is available to validate emails directly in WordPress forms without API coding. **Q: Can NoParam detect disposable email addresses?** A: Yes. Disposable email detection is included in all plans. Role-based email detection is also included.
