About - ZeroBounce

Established in 2017.

ZeroBounce is among the most prominent vendors in terms of accuracy. Setting it apart from competitors, ZeroBounce complements the incredible email verification service through performance analytics and adding missing data to your email address list [such as subscriber's first and last name, gender, city, state, country and IP registration information at no extra cost].

An equally impressive feature we found during our audit was seamless 24*7 customer support, available to customers around the clock. With its highly secured data cleansing process, ZeroBounce has acquired some pretty big-time clients; namely Siemens, Tripadvisor, Shopify, Comodo, Allstate etc.

Although ZeroBounce is the premier email validation service, it has fallen behind by not providing ESPs integrations. $35 is the minimum payment amount that ZeroBounce charges for 5000 credits. The credit never expires. But if you were to verify a smaller volume, there are other alternatives you can elect for. Certainly deserving of first place by accuracy, ZeroBounce ranks lower in cost per email verification.

ZeroBounce - Data Protection

ZeroBounce uses “Cloudflare” for surefire content delivery which ensures additional defense against cyber attacks and data breaches. ZB is one of the only email verification services that uses a military grade encryption algorithm to safeguard YOUR files and YOUR personal information.

ZeroBounce ensures data security by encrypting the files as well as protecting them through a password during the process of email verification. Only the registered user will have access to the files. ZeroBounce will never store any data in their system. After the email verification is completed, all the data and related aspects will be erased in maximum 30 days.

ZeroBounce - Privacy Policy

ZeroBounce complies with the EU-U.S. Privacy Shield Framework and the Swiss-U.S. Privacy Shield Framework as set forth by the U.S. Department of Commerce regarding the collection, use, and retention of personal information transferred from the European Union and Switzerland to the United States, respectively.

ZeroBounce - Hosting locations

ZeroBounce hosts its Email verification servers in the European Union.

Anti - greylisting technology

ZeroBounce allows for an comprehensive, 37 minute verification process for the email list because it deploys the anti-grey-listing technology. A lot of remote mail servers will issue a 421 response code initially, then after a period of time up to 30 minutes, they will allow the email address to be validated appropriately.

If any file has an email address that encounters a single 421 response on, it will delay the entire file processing time by up to 35-37 minutes.
