How Impressionwise.com’s email validation works
Impressionwise.com’s email validator works based on the perceived email threat. When uploading your email list, it can identify:
Invalid emails, spam traps, typos, catch-alls, possible bots, abuse emails, disposable domains, and role-based accounts.
It also provides some details on why an email address is perceived as a threat, such as delivery errors, malformed domains, and possible blacklists.

ZeroBounce’s email validation
Compared to Impressionwise.com, ZeroBounce is capable of detecting more than 30 email address types, along with detailed sub-status descriptions, so that you know exactly what’s on your list.
ZeroBounce detects: valid emails, aliases, alternates, invalid emails, disposable domains, spam traps, catch-alls, role-based, abuse emails, toxic domains, possible bots and traps, do not mail addresses, and more.
And - ZeroBounce promises 99% accuracy on email validation with a money-back guarantee.

ZeroBounce saves you money compared to Impressionwise.com
In addition to more affordable email validation with a money-back guarantee, ZeroBounce provides users with free deduplication.
If you upload your database and it contains the same contact more than once, ZeroBounce identifies the duplicate and removes it at no cost. That way, you only pay for the result once.
Impressionwise.com currently doesn’t offer free deduplication to help tidy up your email list.

Impressionwise.com has no solution for Yahoo and AOL-disabled accounts
If you have some experience with email marketing, you know that Yahoo and AOL email addresses can be a risk.
That’s because both email service providers regularly disable accounts that have been inactive for over a year. The problem is that a “disabled” account still yields a “valid” verification result. Until now.
ZeroBounce is the only email verification tool that can accurately identify disabled email accounts. No other provider, including Impressionwise.com, has this technology.

Accurate, affordable email validation is essential. But what does each platform offer to further help you improve your email campaigns and deliverability?
The comparison is straightforward: Impressionwise.com focuses primarily on validation and email list hygiene. However, ZeroBounce offers a full toolkit to help with campaign performance, inbox visibility, email authentication, and configuration.

Get precise email marketing targeting with Activity Data
After you have a list of valid, deliverable contacts, you need to find the best leads.
ZeroBounce’s Activity Data enhances your campaign potential by telling you if a contact has been active in their inbox in a set time frame.
The time range spans from 30-365 days. And, if an email address has been inactive for over a year with a 365+ rating, you know it’s inactive.

Score your catch-all email addresses
If you’ve ever validated emails, you’re familiar with catch-alls. They “catch all” incoming messages that would otherwise bounce because of a malformed email on your list.
The problem is - some catch-alls are quality, and others are a risk.
ZeroBounce solves the catch-all problem by scoring your validated emails. Using proprietary technologies and industry knowledge, your contacts receive a grade from 1 to 10, with the highest scores being active, reliable contacts for your campaigns.

Get instant alerts of email blacklists
Many things can give your company a poor email reputation; poor campaign performance, domain/IP history, messaging a spam trap, etc. With any of these, you run the risk of getting blacklisted.
ZeroBounce monitors your domain hourly and alerts you if your domain or IP has been blacklisted. Find out where the instance occurred, and learn how to take action before it causes lasting damage.

Mobile email validation with iOS
As a busy professional, we know you’re on the go.
Impressionwise.com currently limits email validation to a desktop experience. Conversely, ZeroBounce allows you to upload a list, manage your integrations, score emails, and more from your iPhone or iPad.

24/7 customer support
Finally, Impressionwise.com lacks in its support options. No business hours or contact details are listed on their site, and reaching a support agent on a business day is a matter of rolling the dice.
To compare customer support, ZeroBounce knows how much service matters. You can contact someone 24/7, 365 days a year via live chat or contact the team via phone or email.

Security and privacy comparison
As a business, sharing your contact database is a high-risk matter. Not only are you responsible for protecting your interests, but you also need to ensure you’re compliant with protecting your subscribers’ privacy.
Impressionwise.com is limited in what it shares regarding its protections, but it is GDPR-compliant and deletes your files after 7-10 days for your security.
In comparison, ZeroBounce is proudly SOC 2 Type 2 and ISO-27001-certified and has GDPR, HIPAA, and CCPA compliance. The company partners with some of the world’s top cybersecurity specialists to assist with attack resistance management and penetration testing.
