How is the limit of contacts and events calculated

First, some definitions:

The limit for contacts and events to sync is cumulative ie. it’s a sum of your contacts and email events recorded in Pipedrive. So if you send out a monthly newsletter to 200 contacts, 50 of them open and 5 click, then the total sync count is 255:

Then, if you update a field (ie. industry) of 60 of your contacts in Pipedrive and sync that with Mailchimp, it adds another 60 events to the count, bringing your total monthly sync count to 315.
