Multiple customers with the same email address

[ztank]

Version 3.5.2 here.
Is there a way to have multiple customers with the same email address?
I see the vice versa is possible (multiple email addresses associated to one customer)
Is there anything I can do in the heskik_customers table for the field email to make it possible? If email field wasn't an index would it work? Would it break?
Thanks.

Customers are identified by email so only one is possible per customer.

Not sure what your use case is, but if you don't require customer accounts, you can make e-mail address optional and users can submit tickets without an email address.

My use case is dictated by the fact that some customers do not have an email address or are not skilled to use it. They often ask if they can share the email address of one relative that (younger and more technology prone) has an active email account that is monitored. And unfortunately already is a customer in HESK.
Sometimes we assume we all have and use an email address as we even more often assume everybody has a cell phone and a cell phone number. That is 99.9% of the times true. But not always true...
Instead we all have a name (middle name sometimes) and a last name which unfortunately can lead to some homonymies cases in certain occasions..
Here comes the social security number to the rescue (or CODICE FISCALE in Italy for example)
My 2 cents.
Thanks.

As said, you can make the email address optional in Hesk settings. That should solve the issue of submitting support tickets for someone who doesn't have an email address.
