What email verification options exist and what they mean?

Last updated by Angel Fandino on August 28, 2018 21:20

Valid

A valid email address has been verified as a real email that is currently accepting mail.

SAFE – These emails exist and have been verified for safe sending.

Invalid

An invalid email address has been verified as a bad recipient address that does not exist or is not accepting mail. Invalid emails will result in a bounce.

DON’T SEND – These emails do not exist and are not safe for sending.

Catch-All

This is also known as an “accept 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.

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.

Unknown

We are unable to definitively determine this email’s status. This email appears to be OK, however, the domain and/or server is not responding to our requests. This may be due to an issue with their internal network or expired domain names.

SAFE – If you have a dedicated email server with your own IPs, unknown emails are normally safe for sending.

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.

Role Address

Identify Service-Oriented Email Addresses

Service-oriented emails, also known as, role-based emails are usually assigned to a group of people. In other words, they are assigned to people managing a specific role within a company (Eg. CEO, Marketing, Customer Service). They do not belong to a specific person which makes it a risky email to send to. 

Our customers use this option to avoid sending email campaigns to the ones they are less likely to get a response back from. Worst case scenarios include the users of that email marketing your email campaign as spam or unsolicited email which degrades your reputation and decreases your email deliverability. Some examples of role-based emails include admin, customer, contact, marketing and so on.

Bad Address

Detect and Mark Spamtrap and Complainer Email Address

Bad Addresses are a combination of a lot of things we watch for. We have a massive database of Spam Trap and Complainers email addresses. These addresses have been carefully sourced from most reliable sources, and they provide us with live updates on what is most likely a spam-trap or a complainer. 

Sending to spam-trap is the worst nightmare for an email marketer. They are risking their domain, reputation, IP address, and more. In addition to this, we also have a trained artificial system that recognizes what emails are likely to be spam-trap or of bad quality. We help you eliminate sending to bad addresses.

Free Address

Identify Email Addresses from Free Email Service Providers

Free Email Service Providers, when selected, allows our system to identify if the email address that was entered or uploaded to our system belongs to one of the free email service providers. There are a lot of free email service providers like Gmail, Hotmail, and Yahoo. 

Our Email Validation Software can accurately identify less popular ones as well as the most popular services. We mark them as “True” which means the email address in question does belong to a free email service provider or false. Some of our customers choose to exclude sending to free email addresses because most of them can be used by spammers to create fake emails. Sending emails to these addresses would profit you nothing.

Disposable Address

Identify Email Addresses from Temporary Email Address Providers

Disposal Email Addressing (DEA) refers to providers who supply disposal email addresses to their customers. This helps people protect their real email addresses from getting abused with spammy content. It’s good for the customers who are making use of these services but not so good for email marketers who want to reach them. 

Each disposal email address provider has specific time frames for shutting down a particular email address. We have a database of hundreds of domains that supply these disposable addresses. We help you avoid sending to these addresses and thereby increase your response rates from sent emails.

Did You Mean?

Analyse and Suggest Correct Email Addresses

Typo Suggest is also known as typo correction feature offered by many applications like Microsoft Word and other such utilities. They figure out if you’ve typed something by mistake and offer you suggestion on possibly correct words. Similarly, our software examines the email address you have entered or uploaded. 

It will then, looks for popular email address providers around the world to see if it matches to any of those. If it does, it will come up with what a correct email ID should look like. A good example might be an email address that looks something like this – “user@yaho.com”. This email looks to be correct but it’s very closely associated to one of the most famous email service provider – “yahoo.com”.

EV Score

Assign EV Score based on the Quality of Email Address

EV Score is our internally developed algorithm which tells you the quality of an email address by assigning it a value from 0 to 1. After scanning through millions of email addresses and seeing their deliverability, we are able to accurately assign quality scores to email addresses that you are highly likely to get a response back from. 

We help you increase your ROI by allowing you to make a decision on sending to leads that are highly likely to open and click your email campaign. A higher EV score indicates a good quality email address while a lower score might potentially have higher spam or bounce rate issues. We recommend sending to lower EV with caution. The value itself is anywhere between 0 and 1.
