Question 1

What does EVA do?

Accepted Answer

EVA (Email Verification API) is a free public email validation service accessible at eva.pingutil.com, designed for developers who need reliable real-time email verification without any per-validation cost or subscription. Unlike most email validation services that charge per check or require a paid plan for production use, EVA is entirely free — with no credit limits, no billing, and no credit card required.

The platform handles both single real-time email validation via API and bulk validation through CSV and TXT file uploads, making it suitable for form-level validation at signup and for cleaning larger existing email lists. EVA also implements a smart deduplication policy: if the same email address is validated twice within a 2-day window, no additional credit or charge is incurred (though on this free platform, this primarily means the server skips redundant network lookups for efficiency).

## What the API Does

EVA performs standard multi-step email validation:

- **Syntax check**: Validates the email address format (characters, @ symbol, domain structure).
- **Domain check**: Confirms the email domain exists with valid DNS records.
- **MX record check**: Verifies the domain has mail exchange records configured to accept email.
- **Mailbox check**: Probes the mail server to confirm the specific mailbox exists without sending an actual email.

Results are returned as a JSON object with the validation status and available metadata. The API does not offer spam trap detection or AI-based deliverability scoring — it focuses on the core validity checks.

## Privacy-First Design

EVA's standout characteristic is its data minimization policy: the service stores only the minimum necessary information for the shortest possible processing time. Email addresses are not retained in any database after validation completes. This approach is beneficial for developers building applications in compliance with data minimization principles under GDPR and Nigeria's NDPR, where storing validated email records could create unnecessary data liability.

## Bulk Validation

Beyond the real-time API, EVA supports bulk validation via file upload — developers and marketers can submit CSV or TXT files containing email lists and receive validated results when processing completes, without needing to write API integration code for batch workflows.

## How Developers Use It

1. Register at eva.pingutil.com and generate an API key.
2. Make a GET request to the validation endpoint with the email address and API key.
3. Parse the JSON response for the validation status.
4. Use the result to accept or reject the email address in your application.

Multiple API keys can be generated per account, allowing developers to manage separate keys per application or domain within one EVA account.

## Pricing & Fees

EVA is completely free. There are no per-validation costs, no monthly subscription, no credit purchases, and no usage limits published. The service appears to operate as a public utility tool. No credit card is required at any point.

## Authentication

API key authentication. Keys are generated in the EVA dashboard after email registration at eva.pingutil.com and passed with each API request.

## Rate Limits

Specific rate limits are not publicly documented. As a free public service, extremely high-volume use cases may encounter undocumented limits. For enterprise-scale validation needs, consider a commercial provider (ZeroBounce, Mailgun Validate) alongside EVA for fallback.

## Challenges & Gotchas for Nigerian Developers

1. **No spam trap detection**: EVA does not identify spam trap email addresses — a critical feature for email marketers who need to protect sender reputation. Use ZeroBounce for comprehensive spam trap detection.
2. **No disposable email detection**: EVA does not flag disposable or temporary email addresses (10minutemail, Guerrilla Mail, etc.) — supplement with a disposable domain blocklist if this is a concern.
3. **Free tier risk for production**: Being a free public service without an SLA, EVA's uptime and response times are not guaranteed. For mission-critical production validation (fintech onboarding, KYC flows), use a paid provider with an SLA.
4. **No AI scoring**: EVA provides binary validity results without deliverability risk scores or confidence percentages.
5. **Limited advanced features**: No inbox testing, no email preview rendering, no email finder — EVA is purely a validation tool.

## Company Background

EVA is a free public email validation tool built by PingUtil (pingutil.com), a developer tools provider. The service is positioned as an accessible, cost-free option for individual developers, startups, and side projects that need basic email validation without incurring costs.

## Frequently Asked Questions
