Is it possible to get an arduino to send a custom email when two contacts on the arduino are closed? (Digital pin to ground, etc) I would need it to be able to send 4 separate emails, each sent when it's own set of contacts are closed. Anything helps. Thanks.
This example sketch will send email in some situations, depending on your ISP.

You would need to modify it slightly to get it to send 4 emails.
