10 Best Email Verification Software & Tools 2023

SEON Pros

• Email address maturity: SEON relies on email data breaches for user verification. This is a fantastic way to confirm if an email address is in use, and how long it’s been active.
• Social footprint: Email addresses linked to social profiles or other online accounts prove that the owner actively uses them, so they are more likely to be real. Not to mention all the valuable data you can glean from checking the public sections of the social media profiles themselves.
• Domain information: Is creating an email address with that domain name payable? Are there any security checks? If the answer is no to both questions, it’s more likely you’re not dealing with a high-value client – or worse, it could be a fully-fledged fraudster.

SEON Cons

• Fraud and risk-focused: As it’s primarily focused on revealing customers’ true intentions to mitigate fraudulent attacks, SEON’s email data enrichment can help catch fraudsters, segment your users, and do due diligence – but not conduct some more technical email checks.

• Verifies catch-all emails: Runs email verification twice, employing both traditional methodology and “enhanced clean” to sort through catch-alls. This is why it can claim to be the sole provider that can verify Office 365 emails.
• Convenient options: The solutions are all available via API and either as a pay-as-you-go pricing model or monthly subscription.
