Syntax
Programmers, developers, and IT professionals are all well-versed in the world of syntax errors. Often, we see them in the form of a pesky dialog box after inputting a piece of invalid code. Unfortunately, when these little typos take place while entering email addresses into your CRM, they can wreak havoc on your email marketing lists and upset your analytics.
DON’T SEND – These lines are not an email address in logic.

Spam-trap
A spam trap is a honeypot used to collect spam.
Spam traps are usually e-mail addresses that are created not for communication, but rather to lure spam. In order to prevent legitimate email from being invited, the e-mail address will typically only be published in a location hidden from view such that an automated e-mail address harvester (used by spammers) can find the email address, but no sender would be encouraged to send messages to the email address for any legitimate purpose. Since no e-mail is solicited by the owner of this spam-trap e-mail address, any e-mail messages sent to this address are immediately considered unsolicited.
The term is a compound of the words “spam” and “trap” because a spam analyst will lay out spam traps to catch spam in the same way that a fur trapper lays out traps to catch wild animals. The provenance of this term is unknown, but several competing anti-spam organizations claim trademarks over it.
DON’T SEND – These emails will ruin your sending reputation.

Accept-All
This is also known as a “catch-all”. This is a domain-wide setting where all emails on this domain will be reported as a catch-all. There is no definitive way to determine whether this email is valid or invalid.
A catch-all address is commonly used in small businesses to ensure a company receives an email that has been sent to them, regardless of typos. Additionally, these are also found in larger government, medical and educational organizations. Oftentimes these are in fact valid emails. However, some organizations may utilize this setting as a security feature to prevent unsolicited emails.
Commonly the server will accept all mail and then bounce it back to the sender, which in turn hurts the sender’s IP Reputation.
SAFE – If you have a dedicated email server with your own IPs, catch-all emails may be safe for sending dependent on the overall health of your list.
DON’T SEND – If you use a third-party email provider that requires a bounce rate below 4%, these emails are not safe for sending.
