What is Email Validation?

Simply, Email Validation or Verification (List Cleaning) is a process to check if the email address exists or not, is it a real email address or not? and this is very important in email marketing.

Then it tells you whether the email address is real or not. It extracts the MX records from the email address and connect to mail server to make sure the mailbox really exist for that user/address.

Why is Email Verification Important?

Most Websites have their optin-forms which visitors need to fill in. During this fill up processes, users may, intentionally and evidently, enter wrong email addresses. By accepting them, your email list will be filled up with inaccurate and undeliverable email addresses. If you send email to such addresses, Your Bounce Rate will be higher, and this will negatively affect your mail server reputation. A poor reputation of your mail server IP address will result in blacklisting by popular email services. By verifying email lists and checking to deliver reports, you improve a lot of options: Open Rates, Bounce Rates, Click-through Rates, and Conversion Rates.

What is a Catch-all or Accept-all Email?

This is also known as an “catch-all”. This is a domain-wide setting where all emails on this domain will be reported as a catch-all. There is no definitive way to determine whether this email is valid or invalid. A catch-all address is commonly used in small businesses to ensure a company receives any email that has been sent to them, regardless of typos. Additionally, these are also found in larger government, medical and educational organizations. Oftentimes these are infact valid emails. However some organizations may utilize this setting as a security feature to prevent unsolicited emails. Commonly the server will accept all mail and then bounce it back to the sender, which in turn hurts the sender’s IP Reputation.

SAFE – If you have a dedicated email server with your own IPs, catch all emails may be safe for sending dependent on the overall health of your list.
DON’T SEND – If you use a third party email provider that requires a bounce rate below 4%, these emails are not safe for sending.

What is a Spam-trap Email?

A spam-trap is a honeypot used to collect spam.
Spam-traps are usually e-mail addresses that are created not for communication, but rather to lure spam. In order to prevent legitimate email from being invited, the e-mail address will typically only be published in a location hidden from view such that an automated e-mail address harvester (used by spammers) can find the email address, but no sender would be encouraged to send messages to the email address for any legitimate purpose. Since no e-mail is solicited by the owner of this spam-trap e-mail address, any e-mail messages sent to this address are immediately considered unsolicited.
The term is a compound of the words “spam” and “trap”, because a spam analyst will lay out spam-traps to catch spam in the same way that a fur trapper lays out traps to catch wild animals. The provenance of this term is unknown, but several competing anti-spam organizations claim trademark over it.
