Spam email is a nuisance to consumers and today makes up a significant percentage of all email traffic. Verizon, like all other ISPs, uses industry standard spam filters to protect our customers from being inundated with unwanted spam email, or sending spam to others.
Verizon employs a variety of tools and techniques to protect its network and the customers who use it from spammers and others seeking to bombard, trick or otherwise harm our customers. Verizon’s filters perform an analysis to assess whether the email is or is not spam, mainly by comparing the URLs in a given email against URLs contained in known spam messages. If a match is found within an email intended for a Verizon.net email customer, the message is either delivered to the customer’s spam folder or deleted according to the customer’s preset preference. If a customer attempts to send an email using the Verizon.net email service that contains a matching URL, the customer receives an error message stating the message they attempted to send was determined to be spam and the message is not sent.
If an email is incorrectly sent to the spam folder, a Verizon.net customer can tag the email as “not spam” and new emails from the sender will be sent to the inbox going forward. If a customer feels an email being sent was incorrectly identified as spam, they can notify Verizon of the issue and a correction will be made within an hour if it is determined that the email is in fact not spam.
