The most important feature of an email validationⓘ service is accuracy. If you're not successfully identifying valid and active email contacts, you're leaving revenue on the table.
Let's examine Snov.io and ZeroBounce's email validationⓘ service to see which types of email addresses each can identify. We'll also provide their accuracy rating along with their policy for handling inaccurate results.
Snov.io reports 98% accurate results when uploading your email list for verification.
Note that with this accuracy rating, Snov.io can identify most valid or deliverable email types. However, they cannot identify risky email types, including spam traps, disposable domains, or abuse emails.
Disposable domains are temporary emails that become invalid after a short period. Spam traps target businesses that don't use best email marketing practices for email list hygieneⓘ. Finally, abuse emails belong to known complainers who may increase your spam complaint rate.
Additionally - there is no money-back guarantee on results. They do, however, offer free deduplication, meaning you don't need to worry about paying for duplicate emails on the same list.
ZeroBounce offers 99.6% accurate email validationⓘ with a money-back guarantee.
In addition to its higher accuracy rating, it identifies the highest number of email address types out of any email verification service. That list includes spam traps, disposable emailsⓘ, abuse emails, alternate emails, and more.
The ability to identify more email address types leaves you with consistently fewer than 1% unknown results and more actionable data to improve your email lists. ZeroBounce also offers free deduplication and never charges for an unknown result.
For better email marketing results, you need more information about your email contacts.
ZeroBounce's email deliverabilityⓘ tools provide you with appended data free when uploading your email list for validation. Whenever it's available, your results will come with useful data points like name, gender, geolocation, domain name, and domain age.
If you want even further insights, you can leverage A.I. Email Scoringⓘ and Activity Data to retrieve more insights about your email contacts. Scoring and Activity Data grade the contacts on your list so that you can learn a variety of useful data points, including:
As opposed to enriching your email list for better targeting and segmentation, Snov.io's package focuses on its lead finder, sales CRM, and email warmupⓘ - different tools for finding new potential prospects and preparing future email campaigns. ZeroBounce offers similar tools but offers them separately from email validationⓘ for more convenient pricing options.
