When preparing your document as usual, SignRequest currently allows adding 30 signers on one document. We highly recommend testing such documents before sending it as the document or signers cannot be changed during the process.
Please be aware that with such a document, if one signer declines, the other signers cannot sign it anymore.
If you want to add more signers on one document you have the option of creating a public signing link. You simply share the link with your contacts and they sign as usual. Follow the steps explained in the tutorial below to create your public signing link.
In case you use the bulk send feature you can send the document to up to 1000 signers at once. This, however, will result in up to 1.000 documents each with one signature. Learn more about sending a bulk SignRequest here.
