In our daily business dealings, when executing our marketing strategies, we often work with email marketing, which, in itself, is based on the ability to send product or service content to customers who require it as part of their commercial promotional and consumer activities, an audience interested in and trusting of this information. Your content, meanwhile, comes with prior consent. However, it marks its difference with the antichrist of the virtual email commercial, as is the intruder of spam, its destructive mission apart from harming businesses in their access to customers, stands out in its maliciousness for being invasive, irrelevant and does not request permission before sending messages and is related to malware; so know first, you should know that by opening spam, you are exposing your computer to its content, especially when you do not know who the sender is. Consequently, you will know when email marketing is good because it is merely the way we communicate and promote effective and ethical email communication products or services.
