Rental List (or Acquisition List)

A list of subscribers available for rent or purchase. Usually of people who have requested information on specific topics.

Use of rental lists is highly inadvisable. Often lists can be of poor quality, or may contain email addresses that have been illegally added.

There is a high risk of being labelled as a spammer if recipients were not expecting to receive your emails.

Reverse DNS (rDNS)

A method of determining the domain names associated with an IP address. It’s basically the opposite of DNS, which determines the IP address of a domain.

Email systems check to see if the IP address recorded inside the email matched the sender’s email address. If it doesn’t match then it may treat the email as spam.
