Apsona's Document Merge tool does not have an electronic signature feature. There is no integration between Apsona and Adobe, Docusign, etc. however you can design your merge docs to accommodate signature lines for an e-signature tool to use. Docusign, and possibly other tools, have Salesforce integrations so that you can use a Salesforce file and add a signature field and deliver the file via email. That Salesforce file could be the merged document that comes from Apsona, which can be automatically be added to a Files related list through our Logging Options feature
