Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

EmailValidation API is a REST service from SecureMyData for developers who need programmatic email address verification. It checks RFC 5322 syntax, DNS MX and A records, SMTP RCPT TO responses, disposable domains, role-based addresses, and possible typos. Results are returned as structured JSON with validity, confidence, scores, diagnostic details, and remaining credits. Bearer-token authentication supports single-address checks alongside controlled batch workflows.

The published pricing uses pay-as-you-go deposits rather than monthly subscription plans. The $29 deposit includes 7,435 credits, while larger deposits provide progressively more credits, from 27,777 credits with $100 to 2,000,000 credits with $5,000. Signup includes 25 free trial credits, and credits do not expire. This model can fit teams that prefer prepaid usage and predictable credit balances, while the required deposit makes it less suitable for buyers seeking an ongoing no-cost plan.

Its main technical distinction is the range of validation stages and batch options. Synchronous bulk validation handles up to 200 emails, while asynchronous batches handle up to 10,000 and can send optional webhook callbacks. Server-side caching and rate-limit headers support application workflows, and language integrations cover PHP, Python, Node.js, Ruby, and Go. EmailValidation API is a strong match for developers building controlled verification pipelines; teams that need a graphical interface or a broader non-API workflow should choose an alternative.
