All campaigns must include our properly coded *|UNSUB|* tag in them so that we can insert a one-click unsubscribe URL into your message. There are absolutely no exceptions to this rule. Even if you're sending to just friends. Even if you are sending an internal message. Even if you're sending transactional emails.
To remain in good standing with the ISPs we require automatic handling of all your unsubscribes through our link. This is included as a default in all of our Templates. However if you remove the unsubscribe tag from the footer of the Template you'll have to add it back in the source as noted below.
To set the *|UNSUB|* tag as we require, you can complete the following steps in one of two ways:
Master of the Code Method
- Make sure you're on the content editor on Step 3 in the Campaign Builder (Step 4 for A/B split or RSS to email campaigns)
- Click on the footer to bring up the editor
- Click on the SOURCE button (this is one step further than entering regular content)

- Copy the code provided here
- Click on SOURCE to move back to the editor
- Save your work and you're done.
- When you send the campaign, MailChimp will provide each recipient's unique unsubscribe URL wherever we see the *|UNSUB|* tag.
<a href="*|UNSUB|*">Remove me from this list</a>
Quick 'n Dirty Method
- In your footer, click where you'd like to place your Unsubscribe link.

- Type out what you'd like your subscribers to see and highlight it. In this case, we chose "Unsubscribe".

- Go up to the toolbar and click on the link icon, which looks like a broken chain.

- This will bring up the Link window. Set your Protocol to other and place your *|UNSUB|* merge tag in the URL field.

- Click ok and your unsub link is all setup.
