Types of Email Verification Results (Valid, Invalid, Risky, Catch-all & Disposable)

Email verification tool classifies emails according to various categories in order to enable businesses to know which emails can be sent to. This helps to enhance list quality and prevent delivery problems.
Valid
A valid email address is one that has an open mailbox, a properly formatted structure, and can be used to deliver messages.
Addresses like this can be seen as relatively safe email sources, aiding companies in getting the content delivered to the right people more easily, lowering the bounce rates, and boosting engagement with the real users all the time.
Invalid
An invalid email address could have various things wrong, like the wrong email format, an inactive mailbox, or a domain name that’s entirely made up.
Mailing this kind of address is bound to increase the bounce rate, damage your sender reputation, and drag down your overall email marketing performance too, so timely removal of such emails is a very much step necessary for businesses.
Risky
Risky email addresses may come from temporary users’ accounts, role-based accounts, or even users whose email boxes are not sure of timely delivery.
They are the reason for lower engagement rates, which means that companies must do a thorough check of these emails before putting them in a campaign.
Catch-all
Catch-all domains allow emails to be accepted without a specific address, which makes mailbox verification difficult. Although some are real recipients, others could be so neglected that even if a message is left in their mailbox, they would never know.
This introduces the risk of delivering messages without being able to be sure that the recipient will read or react to them. For this, a very cautious approach is required during email campaigns using such domains.
Disposable
Disposable email addresses are short-lived accounts which are created to be used for a few days only and soon after they are abandoned or deleted.
This type of email address definitely has a negative impact on list quality; they produce very little engagement and may even lead to a higher number of spam complaints, so they are simply not suitable for maintaining communication with the customers and carrying out marketing campaigns in the long term.
With these verification reports at hand, the companies will be able to keep track of their email list, enhance their campaign effectiveness, and be safe from threats to their reputation.
Email Verification vs Email Validation: What's the Difference?
Despite the frequent use of these words interchangeably, it is important to understand that email validation and email verification are two very different concepts. Grasping this knowledge can be very beneficial for companies that wish to have clean email lists.
Email Validation
Email validation is the process of determining the correctness of an email address, whether in terms of the format and the existence of the domain.
It pinpoints syntax errors and misspelled domains in emails, which are prevented from being sent out, allowing companies to avoid basic data entry mistakes and increase the accuracy of the list.
Email Verification
In email list verification, one step higher is taken than email validation. Besides checking the email format and domain as in validation, a verification email would also be sent to the user to confirm if the address is active and can receive emails.
This step involves checking if the email mailbox is available, filtering out disposable/catch-all emails, among other issues, so that bounce rates are minimized, sender’s reputation is safeguarded, and emails are effectively deliverable, leading to more better campaigns.
Knowing the difference between these two processes can help companies in creating better email lists.
Best Practices for Email Verification
Adopting good practices when it comes to email verification will help businesses to have accurate contact lists and ensure successful marketing campaign implementation. Proper verification practices will also ensure proper reputation management as well as communication with the right individuals.
- Frequent Check of Email Lists: Remove any invalid, inactive, and old email addresses from your email list prior to sending out any campaign emails.
- Real-Time Email Validation: Confirm the validity of email addresses at the time of signing up or while filling a contact form.

- Check for High Bounces: Check the number of bounced emails and remove those addresses that often cause bounced emails.
