You have set the addresses you will be sending to like this:

    To      => join(", ", @$em),
[download]

but nowhere have you set $em to anything, so the array is empty, so you have no recipients. A quick SSCCE to show how to pull these AoAs together:

#!/usr/bin/env perl
use strict;
use warnings;

my $user1 = [ [ 'alpha@foo.com', 'beta@foo.dom' ], [ 'gamma@foo.com' ]
+ ];
my $user2 = [ [ 'delta@foo.com' ], [ 'epsilon@foo.dom', 'zeta@foo.com'
+ ] ];

my $TotalEmails = [ @$user1, @$user2 ];

my @to;
for my $em ( @$TotalEmails ) {
    push @to, @$em;
}

my $tostring = join ',', @to;
print "Full list of addrs: $tostring\n";
[download]

See how that works? You don't even really need the intermediate $TotalEmails but I've left it in for clarity. You can now use $tostring when sending your emails and they should all go out.
