No Restriction on Email Recipient List(to,cc,bcc) in $mailto scriptIssue This KB explains the scenario when the email links contain a larger number of recipients populated using $mailto in the email script: Customers use $mailto in the email template script in order to populate the email links which are normally used for email approvals. In this case, when the customer clicked on the email link in the received email, $mailto will be read by email client applications like outlook and prepares to send the email as per the recipient list mentioned in the script.In some cases, if the recipient list is too large then the email client application not able to open the email and throw some error.From ServiceNow end when the customer uses a $mailto script we pull all the recipient's list from the database and add them in the email (.msg file) with a href link which will be opened by email client applications. In this scenario, there is no any such limitation at ServiceNow end on the number of recipients.Observed that there are some restrictions at email client applications due to which some email client applications are unable to open the email if the recipient list is too large. Please find the example below where I opened the $mailto script which contains a large recipient list. Step 1: Click on the link in the received email. Step 2: Link is getting opened via Gmail email client. Can see the 413 error.
