Example: Subscribe to my list

If you include nothing this subject will be used:  "subscribe me"

You can also insert a special subscribe command as required by your autoresponder.

For example Autoresponse Plus' users can insert this Subject:

owner=abc+password=12345+action=subscribe+name={#name}+email={#email}+autoresponder=info

Taken from the ARP manual:

The "remote control" email must be sent to arplus@yourdomain.com and it must have a subject line in the format shown below. Unknown entries can be omitted.

owner=p1+password=p2+action=p3+name=p4+email=p5+autoresponder=p6+p7+TRAp8+ip=p9+drop=p10

The parameters p1 to p10 are explained here
p1: Your owner name
p2: Your password
p3: subscribe or unsubscribe
p4: Your subscriber's name
p5: Your subscribers email address
p6: Your autoresponder's subscription address (without the domain)
p7: plain or html
p8: The tracking tag to be associated with the subscription
p9: The IP address to be associated with the subscriber’s record.
p10: Set to yes if you want the drop rules for the autoresponder to be actioned by this subscription.
For example, the following subject line would be valid:

owner=abc+password=12345+action=subscribe+name=John+email=john@johndoe.com+autoresponder=info+ip=10.10.0.3
