An A/B test list send email is a type of email send that allows marketers to test different versions of an email and measure their performance based on metrics such as opens, clicks, and conversions. The winning version is the one that has the highest percentage of the selected metric. If the winning version shows the percentage by which it out-performed the other version as 0%, it means that both versions had the same performance on the selected metric, and the A/B test was a tie2.

A good way in Salesforce to verify that a record is syncing to a prospect in Marketing Cloud Account Engagement is to check that the Marketing Cloud Account Engagement URL field is not empty. The Marketing Cloud Account Engagement URL field is a custom field that is added to the lead or contact object in Salesforce when you connect your Marketing Cloud Account Engagement account with your Salesforce CRM. The Marketing Cloud Account Engagement URL field contains the link to the prospect record in Marketing Cloud Account Engagement that corresponds to the lead or contact record in Salesforce. The Marketing Cloud Account Engagement URL field is populated when a prospect record is synced from Marketing Cloud Account Engagement to Salesforce, or when a lead or contact record is synced from Salesforce to Marketing Cloud Account Engagement. Therefore, if the Marketing Cloud Account Engagement URL field is not empty, it means that the record is syncing to a prospect in Marketing Cloud Account Engagement.

The score is a numerical value that indicates how interested a prospect is in your products or services based on their activities, such as email opens, clicks, form submissions, etc. The score helps marketers prioritize leads and identify prospects who are ready to buy. Lenoxsoft is interested in following up with IT professionals who are actively engaging with their marketing materials, so the score is the best indicator of their interest level. The grade is a letter value that indicates how well a prospect matches your ideal customer profile based on their attributes, such as industry, job title, location, etc. The grade helps marketers segment leads and target prospects who are a good fit for your business. The profile reflects Lenoxsoft’s ideal customer, but it does not show how engaged the prospect is. The campaign is the first touch point that brought the prospect to your website, such as a Google ad, an email, or a social media post. The campaign helps marketers track the source and effectiveness of their marketing channels, but it does not show how engaged the prospect is. References [Scoring and Grading Overview]

Form handlers allow you to use your own forms to post your data to Marketing Cloud Account Engagement. A form handler is a great alternative to use instead of Marketing Cloud Account Engagement forms. They allow you to fully customize the look of your form and submit data to more than one database. However, form handlers do not support progressive profiling, which is a feature that allows you to display new fields for known prospects and collect more information about them. To use progressive profiling, you need to create a Marketing Cloud Account Engagement form and enable it in the form settings
