Email List Cleaner: A Privacy-First, Free and Open Source Solution

#web #opensource

EmailListCleaner.org is a free, open-source tool designed to help you clean and validate email address lists while keeping your privacy intact. This privacy-first solution ensures that no one, including the developers of the tool, has access to your data. With Email List Cleaner, you can easily validate email addresses without compromising security.

How Does Email Validation Work?

Email List Cleaner performs two key validation checks:

Syntax Check: This ensures that the email address is formatted correctly (e.g., user@domain.com).
Domain Check: The tool checks that the domain in the email address is valid and configured to accept emails.

While the tool can’t guarantee 100% validity, it provides an accurate indication. If Email List Cleaner marks an email address as invalid, it’s highly likely to be incorrect. If it says the address looks valid, it only means the format and domain are correct, but it doesn’t confirm that the email is actively in use.

What’s more, almost the entire email validation process occurs directly within your browser, meaning your data remains private. Only the domain portion of the email addresses is sent to Google's DNS service for domain validation, and you can verify this process by reviewing the open-source code of the project.

Key Features of Email List Cleaner

Email List Cleaner isn’t just about syntax and domain validation—it also includes several additional features to help you clean your email list further:

Disposable Email Addresses: It flags temporary, one-time-use email addresses commonly used for spam or short-term purposes.
Role-Based Email Addresses: The tool detects role-based emails like info@example.com or support@example.com, which are typically associated with a department or function within an organization, rather than an individual.
Duplicate Email Addresses: It identifies and removes duplicate email addresses from your list. This feature supports email providers that ignore dots in local parts or use email tags (e.g., john.doe@gmail.com and johndoe@gmail.com are considered the same).
Unlikely Valid Email Addresses: The tool flags email addresses that might be valid but are unlikely to belong to real users (e.g., nothanks@example.com).
Domains Without Websites: It can also handle email addresses from domains that don’t have a website, even though they may still be valid.

How To Use Email List Cleaner

Using the tool is simple. Just enter your list of email addresses, one per line, in either of the following formats:

Email format: email@domain.com
Name + Email format: Name <email@domain.com>

The tool will validate each address and categorize them into valid or invalid based on your chosen criteria.
