CPM (Cost Per Thousand)
In email marketing, CPM commonly refers to the cost per 1000 names on a given rental list. For example, a rental list priced at $250 CPM would mean that the list owner charges $.25 per email address. We’ll get into buying lists later in this post.

 

CTR (Click-Through Rate)
In email marketing, CTR is the average number of people who click through a link. It is calculated as the number of unique clicks divided number of emails that where delivered successfully, and is expressed as a percentage. The unique clicks refer to the number of different people who click on links within your email message.

Conversion Rate

Dedicated IP

DKIM
DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect email spoofing. It allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain.[1] It is intended to prevent forged sender addresses in emails, a technique often used in phishing and email spam.

Double Opt-In (see also single opt-in)
When an email address signs up to be on a email list, it receives an email message to verify that the address owner intended to be put on the list. The address owner must reply or click on a link within the verification message to be added to the list. This is the gold standard in permission marketing.

The recommended method of building an email list, it requires subscribers to confirm their opt in by clicking a link in a confirmation email or responding to the confirmation email in some other way.

Email Campaign

Levels of Authentication
A way of establishing a sender’s identity, and ensure the sender is allowed to send from a given domain.

List Segmentation
Selecting a target audience or group of individuals for whom your email message is relevant. A segmented list means a more targeted and relevant email campaign, thus a higher response rate and less unsubscribes and spam reports.

Mail Merge Tags
A tag code that allows you to customize email messages. Your email list management service then replaces the tags with the appropriate information gathered from your database.

For example, “Hi [NAME], how are things at [COMPANY]?” would generate “Hi Bob, how are things at XYZ Company?”

Open Rate
The percentage of emails opened in an email marketing campaign, or the percentage opened of the total number of emails sent.

This indicates the number of people who opened or viewed a particular email message. Open rates are tracked by having a client or browser display an HTML IMG tag. However, due to many having this feature disabled by default, this rate is oftentimes an understatement of the actual amount of opens.

Opt-In (or Subscribe)
A process when a user signs up to receive email marketing messages via web form, paper signup sheet or other method.

To opt-in or subscribe to an email list is to choose to receive email communications by supplying your email address to a particular company, website or individual thereby giving them permission to email you. The subscriber can often indicate areas of personal interest (e.g. mountain biking) and/or indicate what types of emails they wish to receive from the sender (e.g. newsletters).

Opt-Out (or Unsubscribe)
When a subscriber chooses not to receive email communications from the sender anymore, and requests removal from your email list. It is legally required that you provide a clear way to opt out in every email you send.

Pay per click (PPC)
An online advertising model where you pay for each click that is made on your advertisement within the search engines.

Personalization

Read or Open Length
A measure of the length of time a person opens the email until they close it.

Relative URL
A URL that only specifies the document name or path relative to its context.
For example, on the MailerMailer website, the relative URL for the ‘Contact Us’ page is “/contact.html”.

Rental List (or Acquisition List)
Not a recommended email marketing technique, it is a list of prospects or a targeted group of recipients who have opted in to receive information about certain subjects, usually targeted by something like interest, profession, or demographic information.

Response Rate
The total number of responses received from a particular campaign. It is calculated as the people who open and click on links within your email message divided by the number of people who received the email message; it is expressed as a percentage.

Sender Score
A free service of Return Path, it’s a reputation rating from 0-100 for every outgoing mail server IP address. Mail servers will check your Sender Score before deciding what to do with your emails. A score of over 90 is good.

Shared IP
A less costly option than a dedicated IP address, it is an IP address from which many people send emails.

Signature File
A tagline or short block of text at the end of an email message that identifies the sender and provides additional information such as company name, physical address, and contact information.

Single Opt-In
A single opt-in list is created when users sign up for email communications, but don’t confirm the action. This means they can be signed up for a list by someone else, and as such is not a recommended way to build a healthy email marketing list.

When an email address signs up to be put on an email list, it gets on the list without further verification. This means that people can signup others addresses without their permission.

Soft Bounce
A soft bounce is the failed delivery of an email due to a temporary issue, like a full mailbox or an unavailable server.

An email message that is undeliverable that could be due to: the recipient’s mailbox being full, the attachment being too large, or a there being a connection problem. This may be a temporary problem.

Spam (UCE = Unsolicited Commercial Email)
Email sent to someone who has not opted-in or given permission to email to the sender. Over 90% of email sent is classified as spam.

Unsolicited email; also known as “junk email.” Email service providers prevent messages they grade as potential spam from reaching their customers’ inbox. Email recipients also can mark a message as spam, even if it is from a credible source.

Spam Cop
A paid spam service that plants their own emails and monitors who harvests the address and spams it.

Spam Trap
An email address that was once valid, but no longer is. If you email this address, you’ll receive a hard bounce notice. When the mail server sees consistent traffic going to the dead email, however, they can turn the email into a spam trap. It will stop returning a hard bounce for the known bad address, and instead accept the message and report the sender as a spammer.

In other words, it is an email address posted to the Internet as bait for spam. If you send a message to this address, you could suffer penalties including being blocked. Sometimes people post these bait addresses to legitimate email lists as a way to attack the list owner. This is where things get fuzzy, so it is always best to have opted in addresses.

Split testing – A/B split testing
When you divide your list into two categories and deliver an almost identical email to each category with one changed element, or variable, to test.

SPF
Short for ‘Sender Policy Framework’, it’s a DNS record that says on whose behalf an IP or domain sends email.

Whitelist
Instead of listing IP addresses to block, a whitelist includes IP addresses that have been approved to deliver email to a recipient.
