Setup -> Email Administration - > Email Deliverability
Set to "No Access"
This will stop ALL email from being sent which seems like what you want. Be aware though it could cause code to throw errors if you have any code attempting to send email without checking availability first.
I know this is old and might be pretty basic, but if the above steps did not work, check that the profile the user has is associated with the community.
From Setup | Feature Settings | Communities | All communities.
Select Workspaces next to the Community where you want to add the user as a Community Member
Select Administration | Members | Select the user's Profile | Click on Add. Click Save.

"Activity" can be either a Task or an Event. I'm not certain if you're referring to only Tasks or not. Basically, you're talking about Time-Based Workflow. You'd want to create workflow that fires on Task or Event. Assuming you're referring to Task, your workflow should look something like the following:
(First, you don't know if the previous task will have been completed or not. It could easily be overdue by 30 days, so I'll base this on that assumption)
Evaluation Criteria: Evaluate the Rule when a record is created and any time it is subsequenty edited to meet the criteria.
Rule Criteria: Run this rule if the following rule evaluates to true:
Save it and add a Time Trigger
Workflow Time Trigger Edit
Save it and click on the drop-down "Add Workflow Action" to "send an Outbound Message". Create the email template to send the message to the account (or user responsible for the account) related to the task.
If you want the same to apply to Events, you'll need to duplicate the process for Event. Unfortunately without the use of a plug-in like Breeze 3.0, there's no way to evaluate both rules at the same time.
