The answer is: IT DEPENDS.
It depends on the type of campaign you send, the type of subscribers you have and the goals you have set for your email marketing campaigns.
Before you decide to delete a contact, you should carry out a detailed analysis to understand the statistics of your campaigns, analyze why your email has not been opened, the average opening rate of this subscriber with previous campaigns and the structure and content of your emails.
To make a decision, it is also important to know how email openings are counted, and to study other alternatives like creating segments to send emails only to those contacts who previously opened a campaign or clicked on a link in it.
