Accommodating alternative column values

In data made available from a state regulatory agency I find a few instances
where a facility contact has two email addresses. While multiple locations
are accommodated because they're in a table separate from the facility name
and details, all people associated with a facility and location are in a
'people' table with only one column for an email addresse.

While I could enter an additional email address in the 'comment' column if
I'm entering data for a single facility, I'm reformatting the downloaded
data so I can insert all new table data from one .sql file. Is there a way
to accommodate multiple email addresses other than entering both with a
forward slash separating them in the varchar(64) email address column?

Suggestions appreciated,

Rich
