Although you can't email forms and packets directly out of Systemize as you do in CounterGo, you can attach the PDF to an external email if you print a packet to a pdf file. You can even change the way your browser handles PDFs so that they launch in Adobe Acrobat. From there you will see an email icon, as shown below.
Browsers like Chrome, Firefox and Microsoft Edge change frequently, so you will want to refer to your browser's Help documents to learn more about how to change the way PDFs are handled.
Adobe Acrobat will then let you choose between sending a link to the PDF or attaching the full PDF file.
Refer to Acrobat Help for more information.
