Typically, the process begins with a business identifying a suitable email list or newsletter that aligns with their target audience. The business then negotiates with the list owner or publisher to determine the cost and placement of the ad. Once the terms are agreed upon, the ad is designed and sent to the list owner, who then incorporates it into their email communication. After the email is sent, performance metrics such as open rates, click-through rates, and conversions are tracked to evaluate the success of the campaign.
