You should search this forum before posting questions; I did search on email+cell and got a few results :

For example, this post answer does almost exactly what you want to do.

EDIT following your edit :

use an IF condition.

Something like this :

    var cellG = ''
    if(cell.indexOf('D')!=-1){ // = if you edit data in col D
cellG = sheet.getRange('G'+ sheet.getActiveCell().getRowIndex()).getValue()
// add more condition if necessary and/or send your mail (cellG contains the value in column G of the active row
}
    Logger.log(cellG)
