There are some popular e-signature software solutions that you may have already used, including DocuSign, Dropbox Sign (formerly known as HelloSign), PandaDoc, signNow, eversign, and pdfFiller. While these are all convenient options, most require subscriptions, have few to no automation features, and may not be the right solution for you.
Jotform Sign is a new alternative. With Jotform Sign, you can easily add signature fields to a document and automatically gather signatures. Jotform is free to use; features a simple, intuitive design; and lets signers submit their signature using any device.
