Mailchimp pricing history
Mailchimp still anchors “what should email cost?” conversations for small clients. Contact-tier changes are easy to miss if you only look monthly.

What a timeline looks like
This sketch is an example of the product, not a record of Mailchimp's prices. A real timeline starts when you monitor the page.
Day 1 · Baseline
The listed plans and amounts are saved. Nothing is called a “change” yet.
Later · Price
If a listed amount moves, you get an instant email and a new point on this timeline.
Same week · Messaging or feature
Copy and feature claims wait for the Monday note unless they ride along with a price.
