To message your pre-admission pupils parents navigate to Pupils > Pupil List and use the filter to select  Pre-admissions:

Once filtered,  you can either select specific pupils from the list using the tick boxes, or leave the tick boxes to automatically select all pupils.

Use the Pupil Actions drop down box to choose to send either an SMS or email.
