Whenever you send an email blast, an folder gets created in Salesforce automatically for each email blast you sent using the PK4Connect.
The Email Blast name is a combination of Email Blast autogenerated number, and the Email Blast sent date.
e.g: EB:0010-18-11-2020 (Email Blast sent on 18th November 2020)
The folder has the details of the total number of emails sent in the email blast, Np. of emails delivered, No. of emails opened from the Email Blast, No. of emails Bounced, No. of recipeints that clicked the Unsubscribe, etc.,
To see the detailed information on the email blast, go to the Email Blasts tab and click the name that is under the Email Blast Sys-Name column.
