Glossary and Definitions

After verifying a list, or integrating your contacts from another platform, you will be able to see the statuses of the contacts. It will either be Deliverable, undeliverable, risky, or unknown. 

Deliverable: A deliverable result means that the recipent’s mail server states the recipient exists.

In layman's terms a Deliverable email is one that is valid an can have emails sent to it.

Undeliverable: An undeliverable result means that the email address does not exist, or is syntactically incorrect (and this does not exist).

Undeliverable means emails sent to this address will be sent back, or 'bounce'.

Risky: A risky result means that the address has quality issues that may result in a bounce or low engagement. Therefore, use caution when sending to risky addresses. Accept All emails, Disposable emails, and Role addresses are classified as Risky.

Unknown:  An unknown result is when we were unable to get a response from a recipient’s mail server. This often happens if the destination mail server is too slow or temporarily unavailable.

After an email is classified as either deliverable, undeliverable, risky, or unknown, Emailable will give you the reason why.

 

A breakdown of the verification statuses

There are many different reasons why emails are considered as deliverable, undeliverable, risky, or unknown. Here are some of them.

Invalid Email:  This means a specified email does not have the valid email address syntax.

Invalid Domain: The domain name does not exist or is not configured to receive any types of email.

Rejected Email: This email address was rejected by the SMTP server, email address does not exist. 

Accepted Email: Email address was accepted by the SMTP server, it does exist.

Low Quality: Email address appears to be deliverable, but deliverability cannot be guaranteed.

No connect: Emailable could not connect to or find an SMTP server for this email.

Timeout: SMTP session timed out or DNS query timed out.

Invalid SMTP: SMTP server returned an expected/invalid response.

Unavailable SMTP: The SMTP server was unavailable to process our request.

Email Classifications

There are many types of email addresses people use. From personal email addresses, to work email addresses and even marketing/newsletter emails. Emailable gives you the breakdown of all emails verified, so that you can get a better sense of what type of contact base you have! With each verification result, you can see what emails are considered Role, Free, Disposable, and Accept All

Role Email Address: This is an address that is typically associated with a job title or function instead of a person. An example of this might be sales@myjob or support@myproduct etc. Sometimes, mailing to a role address can result in a lowered open rate because the email is not viewed for promotional purposes. Emailable would generally advise against having role email addresses in email marketing campaigns.

Free Email Address: Emailabe is able to identify certain email addresses that are using free email providers such as Gmail, Yahoo, and Hotmail. This being said, it isrecommended to send to Free email addresses, as a large percentage could be personal email addresses.

Disposable Email Address: Disposable email addresses come from domains or services which enable users to create one-time email addresses in order to receive initial communications from a service and then are discarded. Examples of this can be account activation emails, or order notification emails (like Amazon Marketplace emails). It is highly recommended that you do not use disposable email addresses in your email marketing lists. 

Accept All Email Adresses: There are some domains that accept all email you send to them, even if the email is not valid. After an email is sent, the recipient mail server may silently discard the message or send a bounce message right after. If this is the case, Emailable cannot fully guarantee an email will be delivered to a user’s inbox. We suggest that you take some caution when sending to Accept All addresses, as there might be a chance of increased bounces or a lower open rate of an email marketing campaign. 

Other Terms

CSV: A CSV is a type of spreadsheet saved in a Comma Separated Value format. They are typically used for transferring large lists of contact information between platforms.

Sender Score: Your Sender Score is simply put: your brand's reputation for sending non-junk emails. This is scored by how many of the emails you send wind up in junk folders, or aren't delivered at all. Your sender score can be damaged by not filtering out emails that are fake or unreachable and getting those emails sent back to you as 'undeliverable'.
