I "subscribed" to Signaturely by buying their Appsumo deal.
We have been using esignature solutions in our company since 10 years starting from Echosign then moved to signrequest.
Signaturely's UI is very modern and sleek and I had very high expectations of it. I hoped to move from signrequest to Signaturely but their LACK of Zapier/Integromat integration prevented me doing so.
Then they launched their API and Zapier integration and this is the main reason why I would NOT RECOMMEND them. They are asking 99 USD per month for 50 signature requests via API. I can do unlimited documents for 7 euros (per user) using signrequest.
If you are running a business and want to streamline the processes as much as possible then you normally try to prevent your staff logging in into different systems just to do simple tasks , in this instance to send documents to be signed. Zapier / API access are crucial to trigger document send requests from CRM but the cost attached to it is very high in signaturely.
I still wish them good luck :)
