Email Validation
What is the difference between Valid, Invalid, Unknown or Catch-All terms in the report?
Every email is primarily categorized as either Valid, Invalid, Unknown or Catch-All:
- Valid - After a successful SMTP transaction, if receiving mail server accepts the email address, it will be marked Valid Email Address. Sending emails to the addresses which are marked as "Disposable" is not recommended, even though the email address is valid.
- Invalid - An email address will be marked Invalid if it is syntactically incorrect or an email account does not exist on receiving mail server.
- Discretionary - We are able to conclude that these email addresses do not represent a threat to your online reputation, yet we are unable to conclusively verify that these addresses are deliverable. In order to provide to you additional detail and insight into the results obtained, we also include the following sub-classifications: Catch-All, Greylisted, Connection Timeout and Indeterminate. We advise sending this group initially on a separate network (domain/IP) to confirm bounce ratio is within acceptable norms before sending through your main sending network.
- Catch-All - A catch-all email address is an account that receives emails sent to any incorrect email addresses of the domain. When configured, emails sent to any email address associated with the domain should not bounce, but in some cases, it may reject later.
Does an email address marked "Deliverable" have no chance of bouncing?
Depends on the freshness of the validated result, we can guarantee that at the time of the scan resulting in a classification of "deliverable" email addresses won't bounce.
What does the “Catch-All status” mean?
Sometimes receiving mail servers are configured such that it accepts all emails sent to any incorrect email addresses of the domain. This can be usually seen in business email addresses. When configured, emails sent to any email address associated with the domain should not bounce, but in some cases, it may reject later. That is why the safe to send flag is marked as risky. We do not recommend to send emails to “Catch-All" addresses or send it slowly with caution. Deliverability for such addresses is not guaranteed.
What does the “Disposable Email” status mean?
There are certain service providers that generate temporary email addresses for a short period of time, like a few hours to a few days. Such addresses are known as "Disposable Email Addresses". Generally, disposable emails are created to receive initial account activation or confirmation emails for sites like discussion forums, e-shopping etc. and dispose off automatically after a given time period. Sending emails to such addresses increases the bounce rate so it is not advisable to send emails to "Disposable Email Addresses".
What does the “Role Account Email” status mean?
Role-based email addresses are such emails that do not belong to individuals, but to a department, designation or company. The owner of Role-based addresses often changes. Further, the email may be forwarded to multiple recipients. Sending newsletters or campaign emails to such addresses may have a negative impact on your open rates or may lead to spam complaints. Hence, it is not recommended to send any promotional or marketing emails to Role addresses. Most email marketing services reject such role addresses.
Is there any risk that the user IPs and domains get blacklisted by using Impressionwise service?
All processing is done on Impressionwise servers, the user IP addresses and domains are not affected in any way by the Impressionwise service - absolutely no blacklisting risk for the IPs and domains.
Does Impressionwise send any email to do the validation?
No, it does not. Impressionwise utilizes DNS and SMTP protocol functionalities to validate email addresses without sending any messages to external mail exchangers. Our standard verification process ensures accurate results without initiating email delivery. The only exception is when a user specifically opts for Catch-All validation, where an additional step is taken to determine a definitive valid or invalid status.
How often is email verification required?
Depends on the freshness of the result. It is highly advisable to verify before triggering any mass email blast to minimize bounces, improve conversion rates and stay on the good side of ISPs and regulators.

Can Impressionwise be used for real-time email verification?
Yes, many of our users integrate our real-time API to verify email addresses instantly at the point of capture. See our
Integrations page to learn more about how it works.
What turn-around time can I expect for real-time verification?
- Real-time verification is nearly instantaneous for most major free email providers like Gmail, Yahoo, Hotmail, and AOL, covering the majority of the email user base.
- Impressionwise has optimized the turnaround time for business email addresses as well.
How can I validate the email addresses?
Email addresses can be validated through multiple methods:
- Instant Validation: Receive verification results within seconds.
- Bulk Validation: Upload email lists up to 8 million emails per file.
- Real-time Validation: Integrate the Impressionwise API into any platform to verify millions of email addresses instantly.
What types of file formats are supported for bulk verification?
We support delimited (tab, pipe or comma) files with extensions like txt, csv, xls, xlsx, zip, or rar. All other file extensions not listed will not be processed. You may upload a file containing as many fields of information as you wish, yet we require, at a minimum, the email address when scanning the files.
What is a typical batch turn-around times for email verification?
It depends on the size of your file and the type of data in your file. Generally, it takes about 3 to 4 hours to finish the validation of 1 million email addresses.
Does Impressionwise provide gibberish email checks?
Yes, we perform a gibberish check to detect and flag randomly generated email addresses. For instance, an address like rtuj4528@yahoo.com would be identified as invalid and categorized separately.
Why can't all gibberish email addresses be flagged?
Because there is no standard method for determining gibberish, especially in the case of email addresses, many detection algorithms produce more false positives or false negatives, making it difficult to identify the genuine email address. Furthermore, despite the fact that the IETF makes no mention of it, it was difficult to avoid including strict mode gibberish detection in Impressionwise because all major email service providers accept nonsense as an email local component.
Why does my deliverables bounce?
Below are the reasons why Impressionwise can't be 100% accurate with the claimed result:
- Certain mail servers take a long time to propagate the email address state change. Performing validation against the mail server during this propagation period will lead to the wrong result.
- Certain mail servers are protected behind the anti-spam firewall system, where the real status of the email address will be known only by sending an email to the address.
- In case if the email address has forward rules configured, then the actual status of the email address won't be known, as it serves as a proxy.
- Mail server configured for internal use and not following the standard mail protocols cannot be determined.
- In case of certain Office 365 domains, the bounces cannot be identified without sending actual emails as the mail server responds that the account exists, but when trying to contact it bounces.

Plans & Pricing
What is the differences between the Email Verification with Threat Removal and Email Threat Removal Only services?
The Email Verification with Threat Removal service is a comprehensive solution that not only removes email threats, such as spam traps and malicious emails, but also performs email verification and engagement propensity scans. This ensures that all non-deliverable or invalid emails are removed, safeguarding your sending network from being blacklisted and improving overall email deliverability and recipient engagement.
On the other hand, our Email Threat Removal Only service focuses exclusively on the removal of specific email threats, such as spam traps and oversight seeds, and helps ensure you stay off third-party email blacklists. While it does improve deliverability and protects your sending network resources, the email validation scans are limited in scope with no guarantee of individual emails deliverability, nor is any engagement scans performed. This option is ideal if you are primarily concerned with eliminating email-borne, sending reputation threats, such as spam traps, without the need for detailed verification and engagement analysis.
What is the refund policy?
Our refund policy allows for a full refund within 15 days of purchase, provided that none of the service credits purchased have been used. Please note that we do not offer partial refunds. Additionally, any unused credits will not expire, ensuring you continue to receive value from your purchase at any time.
Is there a service result guarantee?
While we make every reasonable effort to identify and remove all known threats and delivery classification elements, please note that due to the constantly evolving nature of the online environment, we cannot guarantee that the results or deliverables will be completely free of all potential threats, traps, or delivery classification elements. We remain committed to delivering high-quality services and continuously updating our methods to address emerging challenges.
