Hi Moseen,
In ACC, you can do it by using the logic of the default register recipients web App.
Basically to send an email you have to use a script like this
// Send confirmation
nms.delivery.QueueNotification("confirmation",
<delivery>
<targets>
<deliveryTarget>
<targetPart type='query' exclusion='false' ignoreDeleteStatus='false'>
<where>
<condition expr={'@id ='+ ctx.recipient.@id}/>
</where>
</targetPart>
</deliveryTarget>
</targets>
</delivery>)
But be aware that you may have a limitation based on the volume and the number of the engine call defined in your license.
Thanks
David
