Ever since the dawn of time, entrepreneurs have been giving away stuff for free. From the “lite” versions of apps, to samples in the grocery story, or straight up assaulting you with perfume every time you walk past the makeup department. Entrepreneurs of all sorts will fall over themselves trying to give you their stuff for free, all in the hopes that you’ll want to come back for more.

An email blast is a single email message that is sent to a large group of recipients. Email blasts are no longer an email marketing best practice. Email marketers should segment their lists and send targeted messages to their subscribers.  All email blasts need to follow the CAN-SPAM Act, include an unsubscribe link, and accurately identify the person or business that is deploying the email.
CPA (Cost Per Action or Cost Per Acquisition) or PPP (Pay Per Performance) advertising means the advertiser pays for the number of users who perform a desired activity, such as completing a purchase or filling out a registration form. Performance-based compensation can also incorporate revenue sharing, where publishers earn a percentage of the advertiser's profits made as a result of the ad. Performance-based compensation shifts the risk of failed advertising onto publishers.[62]:4, 16
Companies considering the use of an email marketing program must make sure that their program does not violate spam laws such as the United States' Controlling the Assault of Non-Solicited Pornography and Marketing Act (CAN-SPAM),[9] the European Privacy and Electronic Communications Regulations 2003, or their Internet service provider's acceptable use policy.
Push marketing is a proactive technique that enables e-marketers to "push" their product/service information to Web visitors or shoppers without their requesting it. Banner advertising, pop-up advertising, e-mail promotion, and spamming belong to push marketing. For instance, e-marketers can rent designated space from Internet service providers such as America Online or MSN for their banner or pop-up ads. Using animated graphics, appealing messages, and links, e-marketers try to lure visitors to their sites to buy their products or services. Many Internet users, however, find such ads annoying and employ software that blocks pop-ups and banner ads. <
