Email Verifier

Email Verifier is a tool designed to validate email addresses and check their deliverability. It ensures that the email addresses in your list are valid, correctly formatted, and capable of receiving emails, reducing bounce rates and improving the overall quality of your email communication.

Features

• Format Validation: Verifies if the email address follows the correct syntax (e.g., user@example.com).
• MX Records Check: Confirms that the email domain has valid Mail Exchange (MX) records for email reception.
• SMTP Check: Ensures that the email server accepts incoming emails for the provided email address.
• Catch-All Check: Identifies if the domain accepts all emails, even if the specific address doesn't exist.
• Disposable Email Detection: Flags temporary or disposable email addresses commonly used for short-term or spam purposes.
• Role Address Detection: Identifies role-based addresses (like support@, info@, etc.), often used by businesses.

Usage

Email Verifier allows you to check a single email or multiple email addresses at once. Here’s how to use the tool:

1. First Input Field: Valid Email Address

• Enter a valid email address in the first field. This is needed because some email providers check for real connections before accepting emails.

2. Second Input Field: Port

• Enter the port number for the SMTP server (the default port is 25). You can specify any port you need to connect to the email server.

3. Third Input Field: Email Check/Verifier

• This field allows you to check one or multiple email addresses. You can enter a single email or bulk email addresses, separated by a newline.

Example of Response Results:

When you check an email or multiple emails, the response will look like this:

[
  {
    "email": "info@domain.com",
    "format_valid": true,
    "mx_found": true,
    "smtp_check": true,
    "catch_all": true,
    "role": true,
    "disposable": false
  },
  {
    "email": "contact@example.com",
    "format_valid": true,
    "mx_found": true,
    "smtp_check": true,
    "catch_all": true,
    "role": true,
    "disposable": false
  }
]

This JSON response provides details about each email's validation, including whether it is:

• format_valid: Whether the email is correctly formatted.
• mx_found: Whether the domain has valid MX records.
• smtp_check: Whether the email server accepts the address.
• catch_all: Whether the domain accepts all emails, even if the specific address doesn’t exist.
• role: Whether the email is a role-based address (e.g., support@).
• disposable: Whether the email address is from a disposable provider.
