Don't see any obvious reasons why Filemaker can't do the job. THere are two basic email options to consider when you set this up. You can use a client computer to send the email out using that computer's email server or you can use an SMTP server. Some folks have had trouble getting the second option to work. You can search this forum for threads on the subject and what fixes solved the problem for them.
There are also a number email plugins that can be acquired to use with Filemaker and you may find that one of them offers additional features that may make your task easier.
Thank you for the reply. We'll give it a go then. All seems to be well at this point.
Have a nice evening.
