What is the maximum number of links that one should put in an email newsletter? In order not to get marked spam.
2 or 3 links are more than enough per each email newsletter.
4 links in each email is the maximum limit according to me.
4-5 is the best number for me. But it depends on your email type. Suppose, if you are sending product updates then more than 5 may also be acceptable but in other case it will be greeted as spam.
3-4 links are enough in an e mail.
