In many cases email addresses work well to uniquely identify users or signers because only a single person actually uses that email address.
However, there are cases where more than one person may use a shared email address. The challenge in these cases is that AssureSign - like many web services - requires users and signers to use unique email addresses.
Fortunately, there is a relatively simple way to differentiate between users or signers that utilize a shared email address without impacting the actual delivery of email to that email address:
Instead of directly specifying the email address (e.g. localpart@domain), an email address "comment" may be added to uniquely identify the recipient (e.g. localpart(comment)@domain). The comment portion is actually stripped out for the actual email notifications.
For example: If John and Jane Doe share the email address email@example.com, you can distinguish between them by using something like the following: jdoe(John)@example.com and jdoe(Jane)@example.com.
For best results we recommend including only letters and numbers (no symbols) in the comment portion of the email address.
