verify^5cr

Details

Verify the validity and deliverability of individual email addresses. The verification process performs multiple checks including syntax validation, DNS and MX record lookup to confirm the domain can receive mail, and SMTP-level verification that connects to the recipient's mail server to check if the specific mailbox exists—all without sending an actual email. Additional checks detect disposable and temporary email providers, identify role-based addresses like info@ or support@, recognize known spam traps, and reference historical bounce data. Returns verification status (valid, invalid, disposable, catchall, or unknown), flags for potential issues, suggested corrections for typos, and optional metadata including address parsing details.

Use Cases

Form validation for user registration and signups, cleaning email lists before campaigns, reducing bounce rates for email marketing, preventing fake account creation, validating customer contact information at point of entry, detecting typos and suggesting corrections, lead qualification and CRM data hygiene, checkout flow email verification for e-commerce.

Usage Instructions

Usage guidance provided directly by the developer for this product.

Email Address Validation - Single

Verify individual email addresses for deliverability and validity. Returns detailed results including whether the email is valid, invalid, disposable, or a catch-all, along with optional address metadata and account credit balance.

Actions

verify

Validate a single email address and get a deliverability result.

Required Fields:

action (string): "verify"
email (string): The email address to verify

Optional Fields:

address_info (boolean, default: true): Include additional address metadata (e.g., free email provider, role account detection)
credits_info (boolean, default: true): Include remaining credit balance in the response
timeout (integer, default: 10, range: 1-30): Request timeout in seconds

Example - Basic verification:

{
  "action": "verify",
  "email": "jane.doe@example.com"
}

Example - Verification without extra metadata:

{
  "action": "verify",
  "email": "support@company.org",
  "address_info": false,
  "credits_info": false
}

Example - Verification with extended timeout:

{
  "action": "verify",
  "email": "user@slow-mail-server.net",
  "timeout": 25
}

Response Fields

email: The email address that was checked
result: Verification result (e.g., "valid", "invalid", "disposable", "catchall", "unknown")
flags: Array of flags providing additional context about the address
suggested_correction: A suggested spelling correction if a typo is detected (or null)
execution_time: Time taken to verify the address in milliseconds
address_info (when enabled): Additional metadata about the address such as whether it is a free provider or role account
credits_info (when enabled): Remaining verification credits on the account

Common Workflows

Pre-send email validation: Verify an email address before sending a message to reduce bounces.
Form input validation: Check an email submitted through a signup or contact form for deliverability.
CRM data hygiene: Spot-check individual contacts in a CRM to confirm addresses are still valid.
Typo detection: Use the suggested_correction field to catch common misspellings (e.g., "gmial.com" -> "gmail.com").

Important Notes

Each verification consumes one credit.
Results are real-time checks against the mail server; transient server issues may return "unknown".
For verifying large batches of emails, use the bulk email verification product instead.
The timeout parameter controls how long to wait for the remote mail server to respond. Increase it for servers known to be slow.

Frequently Asked Questions

How do I connect this tool to an external agent?

You can install the local MCP server by opening a terminal and running:
