Email List Cleaner

EmailListCleaner.org is a privacy-first, free and open source email list cleaner. It validates a list of email addresses for free and in a way that no one, including us, has access to them. It performs syntax checks to see whether an email address looks like a valid email address, and it also confirms that an email address has a valid domain name that has been configured to accept emails. It can also detect and flag disposable email addresses, role-based email addresses, and it can also remove duplicate email addresses.
