Mailing CPC (Cost Per Click) refers to a pricing model used in email marketing campaigns where advertisers pay a certain amount for each click generated from the emails they send. In this model, the advertiser is charged only when a recipient of the email clicks on a link within the email and is redirected to the advertiser’s website or landing page. Mailing CPC campaigns provide a way for advertisers to track the performance of their email marketing efforts based on the actual clicks received, helping to measure the effectiveness of their campaigns and optimize their email strategies for better results.
