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.
Here is a simple workaround:
Instead of directly entering the email address (e.g. name@domain), an email address "comment" may be added to uniquely identify the signer (e.g. name(comment)@domain). We strip this extra comment portion out of the email address when sending email.
For example: If John and Jane Doe share the email address firstname.lastname@example.org, 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.
