Update: I would not use Net::SMTP. please refer to Re: instantiating an smtp object post of Email namespace's if you trust them or just write your own Sendmail.

maybe try this. use Carp; to croak" $@"; the errors. 

#!/usr/bin/perl -w
use strict;
use 5.010;
use lib "template_stuff";
use html3;

sub rndStr{ join'', @_[ map{ rand @_ } 1 .. shift ] }
my $new_name = rndStr( 5, 'a'..'z', 1..9);
my $ref_to_name = \$new_name;
my $return_page = create_page($ref_to_name);
say "page is $return_page";
email_link($return_page);
sub email_link{
use strict;
use 5.014;
use Carp;
use Net::SMTP;
use config2;

my $link = shift;
my $sub_hash = "my_ftp";
my $host = $config{$sub_hash}->{'site'};
say "host is $host";
my $phone = $config{$sub_hash}->{'phone'};
say "phone is $phone";
if (exists $ENV{USER} && $ENV{USER}) {
  eval q^
use Net::SMTP;
my $smtp = Net::SMTP->new(Host => $host, Debug => 2)
 or croak "Unable to connect to '$host'. $!";

$smtp->mail($ENV{USER});
$smtp->to($phone);
$smtp->data();
$smtp->datasend("From: $ENV{USER}\n");
$smtp->datasend("Subject: This is your map link\n");
$smtp->datasend("\n");
$smtp->datasend($link);
$smtp->dataend();
$smtp->quit();
^;
croak "Net::SMTP fatal error: $@" if $@;
 }
  else {
   say '$ENV{USER} does not exists or is not defined.';
  }
}
__END__
