Divide up list and email campaigns in batches of 200

Please read and let me know you understand the project. I need to send emails to the following lists in batches of 200 and need to load separate lists into MailChimp. • Palm Springs -2,265 names divided into 12 lists to be put in mailchimp • Park City -3,739 names divided into 19 lists to be put in mailchimp • South Lake Tahoe -2,148 names divided into 12 lists to be put in mailchimp • San Diego -2,471 names divided into 15 lists to be put in mailchimp • Santa Barbara -2,887 names divided into 18 lists to be put in mailchimp I then need to copy the existing campaign and schedule the send to each of the batched lists --and schedule them for 1 day apart starting Tues, 5/12. The lists are in excel spreadsheets and the design is already done. The first list and campaign for 1-200 names in each market has already been put into MailChimp so that it can be copied. Also, the data is confidential.
