I've been doing this to send out satisfaction surveys several days  
after an order is shipped. I just use a perl script run once a day by  
cron. Kevin's suggestions are probably better, but here's my code FWIW.

Watch out for breaking lines.

At end of etc/receipt.html:

[comment] start survey records [/comment]
[seti timeplus12][convert-date adjust="12" format="%Y-%m-%d"][/ 
[if value b_fname][tmp first][value b_fname][/tmp][tmp last][value  
b_lname][/tmp][else][tmp first][value fname][/tmp][tmp last][value  
[flag type=write tables="survey_postship1"]
[perl tables="survey_postship1"]

         my $db = $Db{survey_postship1};

         my $status = $db->set_slice(
                         fname => $Scratch->{first},
                         lname => $Scratch->{last},
                         email => $Values->{email},
                         date => $Scratch->{timeplus12},

         $status = $status ? 'SUCCESS' : 'FAILED to set in db';

Perl script:

use DBI;
use POSIX qw(strftime);
use strict;

my $host = 'localhost';
my $database = 'blah';
my $user = 'blah';
my $password = 'blah';
my $company = 'Blah Company';
my $subcompany = 'Company formatted for Subject';
my $mailprog = "/usr/sbin/sendmail -t";
my ($code, @delete_uids) = '';

my $dbh = DBI->connect("dbi:mysql:$database:$host", $user, $password);

my $sth = $dbh->prepare('SELECT s.code, s.fname, s.lname, s.email,  
s.date, o.description, t.status FROM survey_postship1 as s, orderline  
as o, transactions as t WHERE s.code=o.order_number AND  
s.code=t.order_number GROUP BY s.code');
$sth->execute() or die $dbh->errstr;
while (my @data = $sth->fetchrow_array()) {
   my $code = $data[0];
   my $fname = $data[1];
   my $lname = $data[2];
   my $email = $data[3];
   my $date = $data[4];
   my $item = $data[5];
   my $status = $data[6];
   if (&is_time($date,$status)) {
     push (@delete_uids, $code);
foreach $code (@delete_uids) {
   my $sql = q{
         DELETE FROM survey_postship1
         WHERE code = ?
   $sth = $dbh->prepare($sql);

sub is_time {
   my $date = $_[0];
   my $status = $_[1];
   my $current_date = strftime("%Y-%m-%d",localtime);
   my $yesno;
   if ( ($current_date ge $date) && ($status eq 'shipped') ) {
     $yesno = 1;
   } else {
     $yesno = 0;
   return ($yesno);

sub mail_user {
   my ($code, $email, $fname, $lname, $item) = @_;
   open  (MAIL, "|$mailprog") || die "Can't open $mailprog $_";
   print MAIL "To: $email\n";
   print MAIL "From: Sum Gui <webmaster\@blahco.com>\n";
   print MAIL "Subject: $subcompany order $code follow-up\n\n";
   print MAIL <<MAIL_TEXT__;
