The Email Validation module is designed to check existing email addresses and determine whether they are valid, invalid, or belong to catch-all domains.
Unlike the Email Finder, this tool does not generate an email – it only validates the one you already have.

​

How Generect Validates Emails

Generect performs a multi-layered validation process to ensure maximum accuracy for every email address. Validation process:

​

Syntax Check

Verifies whether the email is written correctly (presence of ”@”, domain format, allowed characters, etc.).

​

SMTP Verification (core step)

Generect sends a request to the email server to determine:

• whether the mailbox exists
• whether the server accepts mail
• whether the domain is configured as catch-all

The server returns a confirmation or rejection response.

​

Catch-All Detection

If a domain accepts all emails – even for non-existing addresses – Generect marks it as Catch-All.

​

Additional Signals

The system also analyzes:

• historical deliverability data
• previous validation results
• domain behavior patterns

This helps improve accuracy when servers use strict anti-spam or anti-bot protection.

​

Possible validation statuses

• Valid – the address exists; the server confirmed mail acceptance.
• Invalid – the mailbox does not exist or the server rejected it.
• SMTP – the server does not provide a clear response (common on protected domains).
• Catch-all – the domain accepts any email, real or not; true deliverability is uncertain.
• Unknown – the server did not respond or provided an ambiguous response.

​

What the user receives

• A clear validation status (Valid / Invalid / Catch-All / SMTP / Unknown)
• Technical verification details
• Automatic logging in Validation History
• Ability to export, filter, and clean lists based on validation results

How to Validate a Single Email (Email Validator)

The Email Validator section allows you to manually check one email at a time. How it works:

1. Go to Email Validator.
2. Enter an email address into the form.
3. Click Validate email.
4. The system performs an SMTP check and displays the result.

Results appear in a table showing:

• Email
• Status (Valid / Invalid / Catch-all / SMTP / Unknown)
• Validation date

All validated emails are saved in your Validation History.

​

Bulk Email Validation

This module is used when you already have a list of email addresses and want to validate them all at once. How to run Bulk Validation:

1. Go to Bulks → Bulk email validation.
2. Upload a CSV or XLSX file containing:
   • Email
3. Click Upload file.
4. The system processes each email individually.
5. Results appear in the table and are available for export.

What Generect returns For each email:

• Status: Valid / Invalid / Catch-all / Unknown / SMTP
• Validation source
• Date of validation

Summary statistics:

• % of valid emails
• count of catch-all addresses
• count of invalid addresses
• number of unknown / SMTP results

You can download the cleaned list using the Export button.
