Mach5 Mailer allows you to send personalized email messages to customers, from any database source including Access and Excel, with conditional content, HTML formatting, or attachments. The program also includes an built in mail delivery server (SMTP) for simple use, and a scheduler so you can send your mailing during low-bandwidth or idle hours. The program is easy to use, you can see exactly what your contacts see with message preview, and then click send for fast multi-threaded delivery. You can use your own mail delivery (SMTP) server or the built in server. Your contacts get a personal message with content relevant to just them. Also included is a currency field type so you can send out balance statements or invoices via email. HTML capability allows you to send combined HTML and plain text messages to your recipients. Attachments are automatically encoded and can come from a field in your database so different contacts can get different attachments. Additional features include message filtering, ODBC support and more. Mach5 Mailer comes in three versions. The evaluation version is limited to sending 200 emails at once and adds a tagline to the messages. It can be used freely and does not expire.
