title: Efficient way to integrate Informatica MDM DaaS email validation utility as Cleanse function
body: <p>We have DaaS email validation utility subscription provided from Informatica which we have added as Cleanse function in MDM HUB.</p>
  <p>we are trying to bypass the DaaS utility validation if email from source is coming as blank or null. just to avoid unnecessary use of utility as it is chargeable based on number of hits consume.</p>
  <p>We used &quot;Is String Empty&quot; function in mapping and navigated to some hardcoded value and only allowed valid email value to be passed in DaaS cleanse function. But we see the MDM Mapping is still consuming the DaaS cleanse function and our hits are always decrementing for Null or Blank email values also.  We are looking for some efficient way to smartly handle this use-case.</p>
  <p>Thanks in advance</p>
