What do you like best?

The convince of creating the signing boxes and sending the document straight to the person's email. Additionally, the signer does not have to have an airSlate SignNow account. I enjoy that the most!

airSlate SignNow is the "new normal" of signing digital documents

What do you like best?

airSlate SignNow is a digital way of signing electronic documents shared across the organization. This is very innovative way of sharing digital documents that required signature. As a teacher, I don't need to be physically present to sign in the important documents in our school because airSlate SignNow simplifies our work of doing it. The signing of documents will no longer take time because by just sharing it through email you can easily check and scrutinize the document you need to ink your signature. This software has also functionalities, features and graphical user interface that even a newbie can easily use. The most useful feature of this software is the ability of the signatories to draw the signature and the options provided to select from the available signatures provided by the system. Notifying the signatories is also a great feature of this application.
