Pat is required to compare email metrics like open rates, click and click through rates by Email Client.
Pat when testing emails to improve open rates needs to create dynamic copy based on email client.
Pat after learning that contacts with a particular email client have a very low open rate suspects Pat’s company emails are going into a spam filter and created dynamic website copy to recommend to visitiors from that cohort “allowlist” Pat’s company email domain and provides instructions for popular email clients and the email client used by the cohort is listed 1st.
