Our online email verifier tool lets you find out instantly about the validity, existence, and quality of any email address via lookup queries. Reduce bounce rates, avoid spam traps, and screen new user registrations in real-time.
Email Verification Lookup performs various email address checks for syntax errors, free and disposable addresses, mail server and mailbox existence, and more.
Email Verification Lookup checks if an address was created using a free email service. Such addresses are unlikely to be used in a business environment.
Spot abusive users who attempt to sign up with disposable email addresses from Mailinator, 10MinuteMail, GuerrillaMail, or other 2,000 known disposable email service providers.
Easily detect invalid email addresses that do not follow prescribed Internet Engineering Task Force (IETF) formats with Email Verification Lookup’s complete syntactic email validation engine.
Every valid email address should have a corresponding mail server with its own DNS MX record. Email Verification Lookup can check if an email address has such records and therefore exists.
Email Verification Lookup’s email-sending emulation and SMTP connection techniques let you verify if an address is able to receive emails.
Email Verification Lookup detects catch-all email addresses that are not assigned to a specific individual and may result in hard bounces.
Check any suspicious email address with email verification checks to avoid the hazards of inexistent and invalid email addresses.
Email validation is helpful to drive down your bounce rate, make it less likely to fall for spam traps and end up on someone’s blocklist, and effectively reach your customers to improve both your deliverability and ROI.
Email validation is a healthy practice from a cybersecurity standpoint in that it helps detect malicious actors who often hide behind erroneous or disposable email addresses to execute phishing and spamming attacks while preserving their anonymity.
Consistently verifying email addresses also contribute to your domains’ reputability. Being flagged by third parties as a spammer or ending up on a blacklist as a result of suboptimal email practices can severely damage your reputation and affect operations.
Website business owners and SaaS managers can benefit from Email Verification Lookup to reduce the likelihood of faulty signups and identify B2B leads based on their use of business-branded email addresses.
Illegitimate users who deliberately entered a wrong email address or used a disposable one may be there to abuse your freemium features. They take up your system resources with no intention of ever upgrading and contributing to your ROI.
