Cannot send email to customers anymore (admin problem)

[Princess]

Thank you for the information, I was busy with trying out Mailchimp. I am at the moment busy installing the mailchimp mod. Will this work or will this also overload the server? In that case do I have to add all the newsletter subscribers to mailchimp manually or are there other options to import the newsletter subscribers to mailchimp?

The Email Address Exporter plugin will let you export lists from your store, which you can import into Mailchimp or other services

Thank you for the tip I will use that next time. I already exported the customers_newsletter table to mailchimp, that also worked fine..
