Deliverability.com: Email Glossary

Email Glossary

Bounce
A soft bounce is defined as a temporary problem, such as not being able
to connect to the intended recipient's mail server. A soft bounce is
also recorded when the recipient's mailbox is full or a connection is
refused or dropped, which can occur when the recipient's mail server is
busy. Soft bounces may be retried at a later time.

Bounce - Block
A block bounce is recorded when the error code includes any language
that refers to a blacklist or delivery issue. Blocked bounces can be
generated from the sending IP, domain name, or message content.

Bounce - Hard
A hard bounce occurs when the recipient's mail server replies with 5xx
error, which in most cases means that the attempt to deliver to that
recipient will never succeed. An example of a hard bounce error is
recipient@domain.com does not exist, which commonly occurs when a list
of members has not been contacted recently.

Bounce - Soft
A soft bounce occurs when the recipient's mail server replies with an
error other than 5xx, or never replies at all. An example of a soft
bounce error could be caused by a server that overloaded or a user whose
mailbox is full.

CallerID
The original name of the authentication standard developed by Microsoft
that later became SenderID

CAN-SPAM Act
Passed in December 2003, the CAN-SPAM Act sets basic guidelines for
sending commercial email messages in the United States.

Clickthrough Rate
The % of users that click on a message. This can be calculated using
number of recipients that were scheduled, received the message, or
opened the message.

Confirmed Optin


Conversion Rate
This normally refers to the number of recipients that take the final
action, such as completing a form or purchasing a product or service.

Deliverability
This term describes the overall amount of messages that reached the
inbox and can be attributed to a specific campaign or for a sender overall.

Delivery Rate
The % of messages delivered (not bounced) versus the total number scheduled.

Delivery Service Provider (DSP)
A third party that provides tools for monitoring the Deliverability and
performance of email campaigns. This typically includes seeding the list
to measure Delivery Rates at major ISPs, scanning the content for spammy
words and broken HTML and rendering the content in various MUAs.
Examples include DeliveryMonitor, Pivotal Veracity, and ReturnPath.

Domain Keys
The most comprehensive authentication standard that signs each outgoing
message with an encrypted key. While SPF and SenderID involve making
changing to DNS records, DomainKeys requires senders to change the way
that messages are constructed.

Domain Keys Identified Mail (DKIM)

Double-Optin

Email Service Provider (ESP)
A service that manages a company's customer database or list and
provides tools for sending out different types of emails on a one-off or
automated fashion. Most commonly used for "batch and blast" newsletters
and email marketing, ESPs also provide services for managing
transactional email messages, autoresponders, password reminders, alerts
and more.

Open Rate
The % of users that open an HTML message versus the number of messages
scheduled or delivered depending on the criteria. An open is captured
when a user downloads a small, normally invisible image.

MIME
Multipurpose Internet Mail Extensions - A standard for sending non text
information. Commonly an email message is encoded in a MIME format
allowing HTML compatible MUAs to display the HTML portion only.

MTA
Mail Transfer Agent. This is a mail server used to send and receive
mail. Examples of MTA's include the IronPort A60, Port 25 Power MTA,
StrongMail MTA, and Sendmail.

MUA
Mail User Agent. This interprets and displays email messages. Examples
include Outlook, Eudora, and Mozilla Thunderbird.

NANAS / NANAE
The NANAS group is forum used by the anti-spam community to post
information about messages sent to spamtrap addresses. Posting in NANAS
usually indicate a practice issue. NANAS is only used for posting
information, NANAE is the forum where the anti-spam community discusses
postings in NANAS and other issues related to email abuse. The community
can be fairly volatile - proceed with caution.

Optin
Request to be added to an email list

Optout
Request of a list member to no longer recieve messages

Reputation Service Provider (RSP)
A third party that provides accreditation and reputation services to
senders and receivers. RSPs collect data about bounces, complaints and
other user activity and aggregate it into a master database similar to
the credit reporting system used for getting a loan. This data is used
by receivers to decide which messages are spam or not and used by
senders to monitor and improve their mailing practices. Examples of RSPs
include Goodmail, Karmasphere, Lashback and SenderScore.

SenderID
An authentication standard that goes slightly beyond SPF by looking at
the headers of the message to determine the PRA, or purported
responsible address.

SMTP
Simple Mail Transfer Protocol, the standard used for sending and
receiving mail.

Spamtrap
Spam traps are addresses that have been posted by members of the anti
spam and abuse communities to flush out spammers. If your list or your
affiliates maintain lists that contain spam trap addresses, it usually
indicates a serious issue with list acquisition practices. Spam trap
addresses typically do not complain or request removal, so it is
impossible to determine and remove them from a given list.

SPF
Sender Policy Framework. An authentication standard that specifies what
IP addresses can send mail for a given domain. This is the easiest
authentication standard to implement and is most widely used, but does
not account for the visible headers in the message, such as the from and
reply-to address.

Transactional Messages
Messages that are related to a service the user opted-in to and whose
primary purpose is not to advertise a product or the use of a service.
Typical examples of transactional messages include an order confirmation
after you make a purchase or a bank statement.

Zorch
The "list that shall not be named".
