Mailchimp is a web-based broadcast email application, on this platform you can create campaigns which can later be sent to your existing customers.
Currently DealPOS has been integrated with Mailchimp so you don't need to input customers from dealpos to Mailchimp manually, because all of that can be done automatically.
You can upload the contacts that are on your DealPOS to MailChimp when your DealPOS and MailChimp have been integrated. For example I choose contact with name "Dahla"
Step 1. Go to Upload-Select join date-then click upload
Step 2. You have successfully Upload contact to MailChimp
