I need to be able to create a Drip marketing campaign, using the workflow to assign a series of emails  that would be automatically sent out, over a period of time, once a stage is achieved, or a campaign is assigned.

Example:

I input a new contact which triggers 5 emails to go out as follows:

   1. immediate email welcoming them to my company
   2. 2 weeks later a follow up email
   3. 4 weeks later a reminder email
   4. 2 months later a did you forget me email
   5. and finally a give me a call email.

All these emails would be emailed to any contact that was entered.  I would also like to schedule a series of emails to go out according to a "Marketing Stage" field that I create.  So if they were in Stage 1, a set of emails would go out, Stage 2 would trigger other emails, etc.  Of course these emails would be retrieved from the email templates section of ZOHOCRM.
