Reasons for invalid email addresses

Without understanding the sources and reasons of an invalid email addresses, maintaining a high quality list is essential. Emails are invalid because of the following reasons:

Bad format – All email addresses have simple formats of accountname@domainname.suffix. And, if any of these elements are misplaced or wrong, it will lead to hard bounces, which adversely affects your sender’s reputation. Accounts that have either of these fields duplicated will never reach the target customer. Look out for bad formats and use email address validation regularly.

Bad domain name – If the format of the email is correct, but it doesn’t have an email server associated with it, the address is completely invalid and messages can never be sent. For example, correct domain name emails are: abc@gmail.com, abc@yahoo.com or abc@hotmail.com, and bad domain name emails are: abc@noone.com, abc@noemailserver.com.

Bad account – This happens when an account name doesn’t exist in on the email server. For example, the email of your customer is johnsmith@xyz.com, but you have typed jonsmith@xyz.com.

You can easily verify these addresses using a list verification process and build an authentic customer base.

But, if the quality of your list degrades, your messages are likely to get filtered as spam by the ISPs. It will then affect all your marketing statistics. Focus on using email validation to reach the target audience.
