    b.      Added the following validations.

                                                       ii.     All Plus One Cards are required to be DSCF entered. Note this validation can be turned off if you perform entry planning post presort. To turn off this validation place a "Y" in column 7 of the HEADER Parameter.

    Is this a mandatory patch?  If we don't use the Plus One Card feature, is foregoing this patch an option?

    Hi Gary,

    The MailStream Plus 2025.12 C01 update is not mandatory if you will not be presorting the Marketing Mail Plus One presort.

    Thanks,
