We were stunned when we came across an article by Internet Evolution, suggesting email marketers use Paypal's batch payment function to send mass emails to non-opted-in recipients, with a payment incentive to open the email. The article even states directly, "The sender can simply upload a list of targeted but unknown email addresses and give each a 1 cent payment."
The first true marketing email did not arrive until 1978, when a company called DEC (which became part of Compaq, now HP) sent an invitation to the product launch of a new machine to all addresses in the ARPANET directory on the USA’s West Coast. They were heavily criticized for the act, which broke the ARPANET appropriate use policy, and everyone else was reminded of the rule.
We've heard a lot about whitelisting and blacklisting, but many are unfamiliar with the term "greylisting" and, to a lesser extent, "rate limiting." Greylisting and rate limiting are two additional but lesser used methods which some ISPs may employ to attempt to deal with spam and/or a sudden influx of bulk email.
While we know that there are obvious missteps to avoid when ensuring that your email is not marked as spam, there are some commonly overlooked practices, or lack thereof, that can still cause a legitimate email to be marked as such. One of the biggest mistakes that a well-intentioned organization can make is to not properly manage new subscribers.
We wanted to do a mid-year check-in to remind you to make sure that your emailing practices are staying in tip-top shape, and that your email marketing campaigns were minding their p's and q's to ensure maximum deliverability.

Anybody who sends email has seen them, in one form or another - those SMTP error codes, often returned in bounced email, such as "550 Requested action not taken: mailbox unavailable" or "550 5 2 1 mail from refused spam site." These are often in response to SMTP commands that have 'gone wrong' between your email server that sent the email, and the receiving email server that is unable to deliver it (or refuses to deliver it) for some reason. But what exactly do they mean? And why should you care? ('SMTP' stands for Simple Mail Transfer Protocol.)

If you are not sure about the exact definitions of the various levels of opt-in when it comes to building email marketing lists or other types of email lists, here is a quick review of what each of them mean. Because there is some confusion about what each of them means, especially where one method of list-building may have more than one name, we've created this resource explaining the generally accepted definitions of Double Opt-In, Confirmed Opt-In (COI), Single Opt-In, Opt-In, Opt-Out, and Transactional email for you.  These are the definitions that the inbox providers, ISPs, and spam filters use, and so it's important for you, as an email sender, to know them.
