How do I change the text at the bottom, where it asks them to unsubscribe
By default, the text at the bottom says - To unsubscribe, switch to/from digest, get on/off vacation, or change your email address, click here.
We always have to allow people to unsubscribe, per the CAN-SPAM Act of 2004. However, you can prevent people from using the digest, going on vacation, or changing their email address.
Log into http://database.mail-list.com and Customize Your List > Unsubscribe Settings
This text and link will appear at the bottom of all messages your subscribers receive
If you are including attachments in the email, this text and link will appear at the bottom of each part, of the multi-part email on purpose, to insure that we meet the Can-Spam Act of 2004.
