eSignature (DocuSign, PandaDoc, etc.)
If your eSignature tool generates a signing link, you can embed it in emlen to let your prospect sign the contract directly within emlen.

HubSpot quotes
Just copy and paste the document link to emlen.
Some eSignature tools send emails for signatures instead of providing a signing link. However, depending on your plan, you might be able to generate a link that works with emlen.
DocuSign
Check if you can generate a signing link within DocuSign. You can find more infos how to do that here.
DocuSign also offers a feature called PowerForms, which enables you to create on-demand, self-service documents for signature. The PowerForms URL can be embedded in emlen. Note: PowerForms are available in certain DocuSign plans.
