When an email message is not delivered to the recipient and returned to the sender, we call it bounce. The bounce can be temporary (a "soft bounce") and permanent ("hard bounce").
Bounce messages are a part of email marketing. Sometimes they happen because of problems that are beyond your control, and sometimes they come because something is wrong with your message or your email process setup.
In order to send more successful email campaigns, you need to understand why your emails bounce and what you can do to minimize your bounce rate.
Although the Advanced Email Verifier has a very good email validation success rate, it is simply not possible to guarantee a 100% accuracy level due to certain factors that are beyond our control. The level of accuracy you can obtain depend on the inbound SMTP connection policy of the remote ISP or ESP, reputation of the incoming connecting IPs and many other factors.
To save your time and protect your IP address from being blocked, we added rules for certain email addresses and domains that force the program to automatically mark the email addresses as "Bad" or "Unknown" without even trying to validate them.
In this article we give the detailed explanation of why certain email addresses/domains are excluded by the rules and what to do if you still want to validate them.
Understanding our Email List Hygiene, Verification & Validation Process
Our Email Validation Software like any other email checker tool can determine about 70-90% of bad email addresses. Advanced Email Verifier connects to the email addresses mail server, as part of the validation process, and asks if the user exists but NEVER send an email to the recipient. If the recipient’s server gives the response that the user exists, the Advanced Email Verifier marks the email address as good. If the mail server says that there is no such user, AEV marks the email address as bad. This means that the Advanced Email Verifier classifies the email address depending on the response of the recipient’s mail server.

"Clean Your List from Bad Email Addresses and Invalid Domains and Increase Your Email Campaign Performance by Focusing only on REAL Prospects"
List hygiene plays a role in the delivery race. It is important to maintain a clean mailing list and remove bounced, undeliverable emails because a lot of ISP mail servers have been known to block a sender's email domain for repeatedly sending messages to non-existing email addresses.
If you are getting too many bounces, undeliverables, complainers, and being blocked as a result, Advanced Email Verifier can help when nothing else will.
Advanced E-mail Verifier will check every email address from a database or a mailing list and determine if the e-mails are still valid. Our email verification software is an easy to use, powerful, and reliable utility to verify and clean up your mailing list.
Advanced users who can install the AEV on a Windows server or VPS and setup proper PTR and Reverse DNS records on the server to emulate the SMTP server. Also, AEV can be used by beginners on local computers with dynamic IP if they use the verification through email validation API. This mode requires less time and efforts for configuration and works out of the box. Since the API key is provided by the 3rd party service (Swift Email Verifier), the user must buy the API key from them.
Note that the Advanced Email Verifier is desktop software and the verification depends on the user’s IP address reputation and infrastructure that is why the price is much cheaper than various online email verifier services.

Note that the email address verifier is fast, but not instantaneous. The speed depends on the size of your list, your connection to the Internet, and the speed of the Web. If your list is rather large, you can run it at night.
Is it possible to verify ALL emails with the Advanced Email Verifier?
Although the Advanced Email Verifier has a very good email validation success rate with most free email ISPs or ESP, it is simply not possible to guarantee a 100% accuracy level due to certain multiple factors beyond our control. The level of accuracy you can obtain depends on the inbound SMTP connection policy of the remote ISP or ESP, reputation of the incoming connecting IPs and many other factors.
The email addresses which could not be verified due to one reason or the other are marked by the program as "Unknown". These unknown results in most cases result from Greylisting which is technology that reduces spam by rejecting initial email delivery attempts. The Greylisting works by returning a "Temporarily Unavailable" message to the sending mail server the first (and only the first) time a message is received from a given sender. Hence, it makes sense to retry these validations again after some time has elapsed.
In addition, "Unknown" results can also result from the inability to verify the emails by simulating a message sending to the recipient email server because the recipient email server requires that a REAL message is sent. Thus, it is impossible to verify whether the address is good or not. You won't know definitively until the message bounces because these mail servers won't cooperate or cannot be checked without sending a real message to them.
To address this issue and save your time, we added certain domains that have been known to often refuse email validation attempts to the Rules settings in the Advanced Email Verifier in order for the program to automatically mark all emails from such domains as "Unknown". Therefore, if your email lists contains email addresses from such non-cooperating email domains, the program may not be able to offer you 100% validation success. The success rate does fluctuate and there is no fixed guarantee.
To accommodate for this, the Advanced Email Verifier includes an in-built bounce handling module that can be used to process the bounced emails to the unknown results list.
If the majority of email addresses on your list are from yahoo.co*, aol.com, hotmail.com, live.com, outlook.com and other free domains, email verifier software won’t help you because these ISP don’t cooperate and don’t allow connections from local dynamic IP addresses without reputation. Email addresses from such domains can be verified only from static IP addresses where a real mail server with a good reputation operates.
