Recently, 99Signals published an article on Email Marketing Terms. The article mainly highlighted the customers’ side. While it is crucial for marketers to understand if they are scaring away their users, it is also a much-needed fact that marketers must be well-versed with the email marketing terms and their meanings.
Most often marketers feel an urge to drop big words within their email content. The trick to luring customers is not using jargons, but using the right terminology in the right place. If you are an experienced marketer, you are already aware of all the email marketing terminologies. However, if you are a newbie, fret not. We have compiled the most important and frequently used email marketing terms for you to refer, learn, use and save it.
The Comprehensive Glossary
Before we start with the comprehensive list, we’ll first clear the air of who will benefit from this:
Email marketing terms is not something that will lose its zeal in the marketing industry. This list’s primary purpose is to discuss the real meaning of each term. This will not just help you in framing a rich convertible email content, but also save you (if you are new) from the tedious task of handling the jargons you hear in the name of email marketing terms. Do these terms sound gibberish to you? We’re here to help. We will go ahead with the terms in alphabetical order for an easy reference! 🙂
Email Marketing Terms: A-F
Above the Fold: It is a part of an email message that is visible without scrolling. In web design, print media and email marketing optimizing the content which appears on above the fold section are given particular importance. We live in a world where each email is opened and read only for 51 seconds. Therefore, it is important to give the right first impression to make sure your Emails are read. The content in the above the fold column is going to be read first by the readers. It is up to this section to attract the users. This column determines the success of your email campaign. Originally this was a printing term used to indicate the top of the newspaper. But unlike newspaper the location of the above the fold column is unpredictable. It may be affected by the user’s preview pane, headers places by email programs like Hotmail, etc., monitor resolution and screen size.
Authentication: Email authentication helps verify if the email is from you or your business. It is the process of verifying the digital signature of the sender. It protects a brand, sender or company’s reputation. It is the most important factor to improve your deliverability. There are about four important types of authentication in email marketing. They are SPF, DKIM, Domain Keys, and Sender ID. SPF and DKIM are the most widely accepted forms of email authentication. Below are the five to authenticate your email.
- Authenticate using DKIM and SPF: These protocols have become standard with the arrival of DMARC; a new standard which would enable IP’s to identify and handle unauthenticated emails.
- For all the IP address create a roadmap: This can help you send emails including external and internal sources like your ESP. Authenticating your entire mail stream is necessary to avoid the risk of being blocked by ISPs at the gateway.
- Authentication record on SPF and DKIM should be created then published.
- Make sure to set up your email server to sign an outbound email with DKIM.
- Make sure to test your records: SPF has various testing tools while DKIM has only two testing tools which are the Policy Record Tester and Selector Record Tester.
Blacklist: There is public and private blacklist present, these are IP addresses that have been reported or listed as known source of spam and malware. Most public blacklists are made public. You can gain access to public blacklist for free and sometimes for a fee it can be made accessible.
Block: An email is blocked when mail server or mailbox provider does not provide an email message to be delivered. Some popular mailbox providers block email from domains and IP addresses that have been reported and send spam, viruses, malware or content that violates email policy and spam filters.
Bulk Folder: Bulk Folders are also known as “Spam” or “Junk” folders. Bulk Folders contain emails which can be called as graymail. These emails are difficult to classify. They consist of spams along with important marketing and advertisement emails.
CAN-SPAM Act: CAN-SPAM Act is a law that sets up the rules for commercial email and establishes requirements for commercial messages. It gives the recipients the right to stop businesses emailing them and provides harsh penalties for violation of these laws. The law was released in the US for Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003. Each single email violating this Act can be charged up to $16,000. Therefore, noncompliance can be costly. Following the law is not complicated, below are the main requirements of the CAN-SPAM’s:
- Never use false or misleading headings: The “From,”“To,”“Reply-To and routing information which includes the name of the originating domain and the email address should be accurate and identify the person or company who initiated the message.
- Do not use misleading subject lines: Design subject lines that accurately represent the content of your email.
- Identify messages as an advertisement: The law requires you to clearly and conspicuously display and inform your recipients that your message is an advertisement.
- Inform your subscribers about your location: Your emails should include your valid postal address. It can be your current address, a post office box you’ve registered with the government, or the address of a private mailbox you’ve registered with a commercial mail receiving agency.
- Inform your recipients of a way to opt out from receiving future email from you: Your email messages should have a clear explanation on how the recipient can opt out of getting emails from you. Design the notice in a way that it is easy for any person to recognize, read, and understand the instructions. Use different types of size, color, and location that can improve the clarity. Offer a return email address or any other online way to allow people to communicate their choices to you. Create a menu that can allow a recipient to opt out of certain types of emails, but you must also include the option to stop all commercial messages from you. Be sure that your spam filter doesn’t block the opt-out requests.
- Honour the opt-out requests of your recipients: The opt-out mechanism that you offer should be able to process the opt-out requests within thirty days of sending a message. The recipient’s opt-out request should be awarded within ten business days. You can’t charge any money for this. Once someone has told you they don’t want to receive more emails from you, you cannot sell or transfer their email addresses to any other party, even in the form of a mailing list it would be illegal. But, you can transfer the addresses to a company you’ve hired to help you comply with the CAN-SPAM Act.
- You need to keep track of what others are doing on your behalf: You cannot manipulate the law even if you hire an email marketing team to do your work. Any foul play from their side will affect you and not them.
Click-Through Rate: Click-Through Rate can be defined as the ratio of users who click on a particular link that directs them to a blog, page or desired location to the total who view an email, page or advertisement. It is measured in direct response to email marketing and not the users who came to the link later. It is used to evaluate the effectiveness of an email campaign. Most marketers count the amount of open, or bounce rate to analyze efficiency and success of an email campaign. According to statistics and studies, Sundays have the highest click-through rates than other days of the week.
Click-through rate= Clicks/impressions X 100.
Click-to-Open Rate: Click-to-Open Rate is used to judge the effectiveness of an email campaign. Click-to-Open Rate tells you about the number of recipients that have opened the emails and clicked on it. It is the ratio of unique click-through on links within an email to the total number of unique opens of the email. It is usually expressed in percentage.
Cloudmark: Cloudmark is a privately owned company which provides protection against spear phishing, threats, spams, viruses, phishing attack. The company is located in San Francisco.

Content Filters: Content filters are software filters that block email messages based on words, phrases, text, and email header. The goal of these filters is to identify spams and to filter Junk or Bulk mail folders although this results in “false positive” sometimes. The work of content filtering is to protect recipients from junk emails and viruses. Sometimes big corporations use content filters to inspect outgoing emails to make sure their employees use the appropriate laws. The user sometimes installs content filters; these filters are either installed as separate programs or as part of their email programs.
Deliverability: Deliverability of emails is one of the most important aspects of an email marketing campaign. For an email marketing plan to be a success, it is important that the email reaches the recipient’s mailbox. The most common question of every business and email marketer is “how do I get to ensure that my emails are being delivered to the recipient’s mailbox?” Deliverability is how you measure the success of your emails reaching your recipient’s inbox without bouncing, or being marked as spam. Below are the few ways that can improve your deliverability:
- Do not keep you customers in the dark. Keep them well informed and make sure to keep them engaged. When a user subscribes to your website, send them a welcome mail. You can also send emails consistently to keep them posted.
- Send authenticated emails so that they get delivered to your customers.
- Uses double opt- in options to make sure that the people who sign up for your services get confirmation emails. This move will ensure that you only have recipients who are genuinely interested in your content and services.
- Avoid using unclear and spammy subject lines.
- Do not send emails with too many images.
- Stop sending emails to recipients that never engage. It brings down your reputation and can lower the chances of your emails getting delivered.
- Make it easier for your clients to unsubscribe from your mailing list if they wish to. This lowers down your complaint rate. If a user complains about your contents, quit sending them emails.
- Do not send emails from another domain.
Delivered: Delivered emails refer to the number of emails that were successfully delivered to the subscriber’s inbox or junk folder. It is the Total Number of Emails Sent minus Bounced Emails.
DMARC: DMARC is known as “Domain-based Message Authentication, Reporting & Conformance.” This is an email authenticating protocol. It is a technical specification that is created by an organization to reduce email frauds and phishing threats. It is built on the SPF and DKIM protocols, adding a reporting function which allows senders and recipients to improve and monitor the protection of the domain from fraudulent emails. It is used by all the main mailbox providers such as Outlook.com, Gmail and Yahoo Mail.
DKIM: Domain Keys Identified Mail (DKIM) helps an organization to take responsibility for an email message in transit. It allows the sender to associate a domain name with its email, vouching for its authenticity. It is done by signing the email with a digital signature. The signature is generated by the sending mail transfer agent (MTA) using an algorithm. The organization is the handler of the message either originally or intermediary. DKIM provides a method for validating the domain name from where the message is coming. It helps to develop trust and reputation.
Domain: A domain is a business or organization’s registered name on the internet.
Domain Name System (DNS): Domain Name System (DNS) can be described as a hierarchical and decentralized naming system for services, computers and any resource which is connected to the Internet or a private network.

It may be because these accounts are no longer active or they have lost interest in your brand. Whatever the case is, it is wise to remove them from your mailing list as it can hurt your reputation.
Inbox Placement Rate (IPR): Inbox Placement Rate (IPR) can be defined as the rate of email messages that are delivered to the inbox, versus the spam folder. The formula for inbox placement rate is the number of emails delivered to the inbox divided by the total number of emails sent.
Inbox Placement Rate= Number of emails delivered to the inbox/ Total number of emails sent.
