Attached is a method to send HTML email with FileMaker 14,13,12 for Windows.
The demonstration file attached requires your SMTP server details and then From, To, Subject & HTML code for the body. Optionally CC & BCC and attachments can be sent.
Type in your HTML code and preview the email before sending.
More attachments can be added by modifying the field definition, script and vbscript code in minor ways.
Addiionally, with small modifications to the vbscript code, Gmail or Live (Hotmail,Outlook.com) could be made the SMTP server. To find out the changes, search google for "CDO SMTP email using Windows Live Server".
This DOES NOT use your existing email program.
Hope it helps someone.
