No, as it would be a violation of privacy. Marketers take time to capture social media appending, which highly helps them in branding, reaching customers directly, and several other benefits. The people-to-people approach that social media enables makes efforts to stand out, especially when compared with the ages-old business-to-business or business-to-consumer approach. That's why social platforms are the top priority for many marketers when it comes to branding and spreading their business. However, the facts are terrifying, and almost all Email verifier services DO GATHER YOUR DATA (that's a violation of your privacy), and further use it for their purposes. We do not store any email addresses for our personal use or provide them to any third party. The same goes for Gender Identification. We never invade your privacy, and that is our priority to keep all essential data of our clients safe.

HandySends Email validation service allows you to check email address validity to reduce the number of undelivered mails. That naturally improves your email delivery success rate and reduces your bad email reputation which may result in your email address being blacklisted.

Our system verifies 1,000+ email addresses in 10-15 minutes, i.e. an email address takes around 0.0125 minutes (or 0.75 seconds).

Catch-all domains accept any random email. So there is no way to confirm whether email exists or not. The only way to confirm whether an email is valid or not is to send actual mail. We recommend, to send catch-all emails as a second priority as there are chances of bounce.

Please note that if your registered email address and PayPal email address are different, then we will need to perform an additional verification step to verify whether the payment is authorized or not. You should check the inbox/spam folder of your PayPal email address. You will find an email regarding your order. Please click on the "Confirm Order" link, and your credits will appear. If, for any reason, it is landed in the spam folder, then please move it to the inbox first.
