Overall, I would say my experience with signNow has been positive and I will continue to use this software.

What I like most about signNow is how easy it is to use to sign documents. I do not have to print my documents, sign them, and then rescan them in.

I use it once a month to sign my loan agreements and it makes things so much better easier.

This software makes it super easy to sign agreements, documents, or confidential papers over email due to the social distancing.
