Subject: API login() Shutdown Notice #1
Reply-To: "MailChimp API" <api@mailchimp.com>


Your MailChimp account is using the login() API method which will be disabled in the near future. 
 
This means code you are relying on will most likely stop working - in the mean time, your code will start running slower and slower.
 
If you are not a developer or programmer, and are just an administrative contact for this MailChimp account, you really need to forward this on to your developer or hire one of the experts listed here. 

If you are a developer or programmer, keep reading...
 
Shutdown Details
Your API implementation is using the login() method and should not be. You have used it 272 times in the past week, which is 272 times more than you should have

Starting today we will be inserting delays into all login() calls as previously announced here.
 
This will cause your code to slow down. 
 
As per the link above, the schedule for adding delays is:
• 2011-08-22 : 1 second delay will be introduced
• 2011-09-05 : 2 second delay will be introduced
• 2011-10-03 : 4 second delay will be introduced
• 2011-10-31 : 6 second delay will be introduced
• 2011-11-21 : 10 second delay will be introduced 
•      < we're not that mean, take your holidays >
• 2012-01-16 : bye, bye login() method
You can fix this by:
• Hard code an API Key and you are likely done
• Use the new OAuth2 support
Once your use of the login() method ceases, we will stop contacting you about this.
