Bonded Sender Program
Sponsored by IronPort Systems, the Bonded Sender program identifies legitimate email traffic. Originators of legitimate email can now post a financial bond to ensure the integrity of their email campaign. Receivers who feel they have received an unsolicited email from a Bonded Sender can complain to their ISP, enterprise, or IronPort and a financial charge is debited from the bond. This market-based mechanism allows email senders to ensure their message gets to the end user, and provides corporate IT managers and ISPs with an objective way to ensure only unwanted messages get blocked.
A "Bounced" email indicates that an attempt to deliver an email to a particular address has failed. This may occur if the email address is no longer valid or the intended recipient's ISP and/or email servers were not functioning over a period of 3 consecutive days.

The CAN-SPAM Act of 2003 (Controlling the Assault of Non-Solicited Pornography and Marketing Act) is a federal law that establishes requirements for those who send commercial email. It spells out penalties for spammers and companies whose products are advertised in spam if they violate the law, and gives consumers the right to ask emailers to stop spamming them. Among other measures, the law:
- Bans false or misleading header information. Your email's "From," "To," and routing information – including the originating domain name and email address – must be accurate and identify the person who initiated the email.
- Prohibits deceptive subject lines. The subject line cannot mislead the recipient about the contents or subject matter of the message.
- Requires that your email give recipients an opt-out method. You must provide a return email address or another Internet-based response mechanism that allows a recipient to ask you not to send future email messages to that email address, and you must honor the requests. Any opt-out mechanism you offer must be able to process opt-out requests for at least 30 days after you send your commercial email.
- It requires that commercial email be identified as an advertisement and include the sender's valid physical postal address. Your message must contain clear and conspicuous notice that the message is an advertisement or solicitation and that the recipient can opt out of receiving more commercial email from you. It also must include your valid physical postal address.
The CAN-SPAM Act also provides for penalties for a number of other offenses, which can be reviewed here: http://www.ftc.gov/bcp/conline/pubs/buspubs/canspam.htm

Click-through Rate (CTR), Click Rate
An indicator of response to a given email message, as measured by the percentage of recipients that click on a link enclosed in the email. To determine the click-through rate, divide the number of responses by the number of emails sent (multiply this number by 100 to express the result as a percentage).
Co-registration or Co-Reg
Co-registration is the process of using other websites to generate opt-in email leads that you can add to your mailing list for marketing purposes. When you reach a co-registration agreement with a site or a network of sites, they will ask new registrants if they would like to receive information from your company as well. If the registrants opt-in (choose to receive mailings), they will be added to your mailing list so you can market to them directly.
"Confirmed opt-in", also known as "double opt-in" or "closed loop" in some circles, provides an additional layer of security by requiring that an email account be both subscribed and then verified by a confirmation email before it is added to the list. As a result, only those people with access to the account can respond to the confirmation message, greatly reducing the chance of abuse. For this reason, confirmed opt-in is regarded as the gold standard for secure email marketing.

"Double opt-in", also known as "confirmed opt-in" or "closed-loop" in some circles, provides an additional layer of security by requiring that email accounts be both subscribed and then verified by a confirmation email before they are added to the list. As a result, only those people with access to the account can respond to the confirmation message, greatly reducing the chance of abuse. For this reason, double opt-in is regarded as the gold standard for secure email marketing. See also: Opt-in, Opt-in form
When you build an email and send it to your recipients using VerticalResponse this is an example of an email campaign. Your campaign may be a newsletter or may consist of offers.

They are usually Software-as-a-Service Providers (SaaS) who offer their services in an online fashion. There are also software ESPs.
The Email Sender & Provider Coalition (ESPC) was formed to fight spam while protecting the delivery of legitimate email. The ESPC members have recognized the need for strong spam solutions that ensure the delivery of legitimate email and have been very active in the war against spam. VerticalResponse is an active member of this organization. For more information on the ESPC, visit www.espcoalition.org

The header in an email is the part of the email that is not transparent to the recipient unless they have their "View Headers" turned on. This tells the recipient what servers the email is coming from and what programs are being used to generate this email. Headers contain information on the email itself and the route it's taken across the Internet. Recipients can normally see the "to" (identity of recipient), "from" (identity of sender) and "subject" (information in the subject line) headers in their inbox. You can modify these to influence their decision to open or delete an email.
The announcement recipients see when they open an email. Ideally, the headline expresses the company's value proposition and encourages the recipient to read further.

HTML email is simply an email created with HTML that allows for the display of images as opposed to simple text. Ninety five percent of all email readers have the ability to display HTML emails, which are more visually appealing and attention-grabbing than mere text. However since 2005, many readers have the default where images are "turned off" or not viewable by the recipient. For this reason you need to make sure your recipients add you to their address book so you'll always go into the inbox where images will show.

Opt-out email marketing assumes the recipient wants to receive email unless they specifically ask to be removed from the list – in other words, "opt-out" or "unsubscribe". If readers fail to state explicitly that they no longer wish to remain on the list, they can expect to receive messages until they make their desire known. Response rates tend to be lower when sending opt-out email, so be prepared for this result when you're analyzing your campaigns.
When offering customers further information, such as a whitepaper or article via a link in an email, the payoff is the information they gain access to when clicking on that link.
The practice of only sending email messages to those recipients who have agreed (or asked) to receive them.

In a phishing scam, a spammer, posing as a trusted party such as a bank or reputable online vendor, sends email messages directing recipients to Web sites that appear to be official but are in reality fraudulent. Visitors to these Web sites are asked to disclose personal information, such as credit card numbers, or to purchase counterfeit or pirated products. See also: Sender-ID, Spoofing
Email programs such as Microsoft Outlook, Entourage, and Mac Mail allow users to view email through a preview pane. The preview pane is important to bear in mind when composing the opening lines of an email.

Under single opt-in formats, businesses only mail addresses that have been actively subscribed to their list, typically by completing a web form, filling out a business reply card or sending an email to a specific address. Because the registration process is proactive, a single-opt in policy offers a higher level of security than the opt-out approach, but also has the following limitations:
- Since single opt-in procedure does not require email address verification, it is possible to register other people without their consent, merely by having knowledge of that person's email address.
- A mistyped address or the entry of a bogus email account that happens to belong to someone else can result in a company mailing a customer who has not registered to receive messages.
- Single opt-in email policies are susceptible to spam traps. Spam traps are essentially email addresses or domains that have not registered to receive any email. Therefore, any messages they do receive must be spam. The problem for marketers comes when people deliberately subscribe spam trap addresses to their lists, or one is inadvertently added. This scenario exposes the mailer to blacklisting by ISPs or the organization operating the spam trap.

Soft Bounced Email
A soft bounce is an email message that gets to the recipient's mail server but is returned undelivered before it reaches the recipient. A soft bounce might occur because the recipient's inbox is full and may be deliverable at another time or may be forwarded manually by the network administrator in charge of redirecting mail on the recipient's domain.
A spam trap is a seemingly valid email address used to identify spam messages. The idea is to take an address that hasn't been subscribed to any email lists and monitor the email it receives. As it wasn't subscribed to any email, anything it receives must be unsolicited – in other words – spam.
SPAM or Unsolicited Commercial Email (UCE) is unsolicited email, particularly of a commercial nature. Sending email to people who have not requested to receive messages from you will likely result in SPAM complaints.
SPF (Sender Policy Framework)
An email authentication system that verifies that a message came from an authorized mail server. SPF is designed to detect messages from spammers and phishers who falsify the sender's IP address in the email header.
Email spoofing involves forging a sender's address on email messages. It can be used by malicious individuals to mislead email recipients into reading and responding to deceptive mail. These fake messages can jeopardize the online privacy of consumers and damage the reputation of the companies purported to have sent the messages. Spoofed email often contains phishing scams. See also: Phishing, Sender-ID
Subheads (or Subheadings)
A line within a body of text that serves as a subtitle for the content that follows. Subheads break up paragraphs of copy and make the page more attractive or easy on the eye. They also often act as signposts indicating specific topics, offers, promotions, etc.

The definition of the term Web 2.0 is an evolving one, but it is generally agreed that Web 2.0 refers to a second generation of Internet services that let people collaborate and share information online. In contrast to the first generation, in Web 2.0, the internet functions as a computing platform that serves web applications to end users. In this way, it provides an experience closer to desktop applications than the traditional static Web pages.
Almost all web browsers are capable of displaying four primary fonts properly: Times, Arial, Helvetica, and Verdana, as well as their variants (Arial Narrow, Times New Roman, etc.) If a web developer decides to stray from one of these fonts he or she risks browser compatibility problems and the prospect that their pages may render inaccurately when viewed through certain web browsers.
Whitelists are lists of commercial emailers (including ESPs) who have been approved to send mail through the ISP. The ISP (internet service provider) requires a list of IP (internet protocol) addresses that email will be sent from, and in some cases a test period where the commercial emailer will be approved or rejected.
