Spec sheet

Purpose
The service checks email addresses for malformed, disposable, role-based, and unroutable addresses before they enter a product.Read 4 Oct 2026 · emailverifier.dev
Intended users
The product is designed for product teams adding checks to signups, free trials, lead forms, CRM imports, and other application workflows.Read 4 Oct 2026 · emailverifier.dev
Support
Support is provided by email at [email protected] for account, billing, API, privacy, and security questions.Read 4 Oct 2026 · emailverifier.dev
API and AI tools
The product offers a REST API and a remote MCP server with verify_email and check_domain tools; each tool call costs one project credit.Read 4 Oct 2026 · emailverifier.dev
Bulk output and retention
Bulk results preserve original rows and append status, recommended action, flagged state, signals, and any typo suggestion; completed files expire after seven days.Read 4 Oct 2026 · emailverifier.dev
Bulk verification
The bulk verifier accepts CSV or TXT uploads or pasted addresses, supports up to 100 CSV columns, and allows up to 5,000 unique addresses per job.Read 4 Oct 2026 · emailverifier.dev
Credit usage
Each email verification and domain check uses one project credit, while the public no-key demo allows 10 checks per hour without spending project credits.Read 4 Oct 2026 · emailverifier.dev
Data handling
Single-address checks are not stored in the application usage database, while bulk lists and working results are temporarily stored so jobs can finish after the user leaves.Read 4 Oct 2026 · emailverifier.dev
Domain checks
Domain reports classify a provider as disposable, a known free mailbox service, or neither, and the MCP domain tool returns classification, risk, and mail-routing data.Read 4 Oct 2026 · emailverifier.dev
Payment processing
Stripe processes payment and billing information, and emailverifier.dev says it does not store full card numbers.Read 4 Oct 2026 · emailverifier.dev
Results
The verifier distinguishes deliverable, risky, undeliverable, and unknown outcomes so an uncertain result is not automatically treated as a failure.Read 4 Oct 2026 · emailverifier.dev
Security practices
The service says passwords, API keys, verification links, and password-reset links are stored as one-way hashes, and account sessions use secure HTTP-only cookies.Read 4 Oct 2026 · emailverifier.dev
Verification signals
Checks include address structure, likely typos, mail-routing DNS, provider type, disposable and role signals, and mailbox acceptance or catch-all behavior when available.Read 4 Oct 2026 · emailverifier.dev
