Mailchimp's Essentials Plan is also free but comes with limitations on subscriber numbers and email volume, which might restrict its utility for high-volume campaigns.

The paid Blaze Plan of Firebase Cloud Messaging varies based on usage and regional configurations, making it less predictable in cost compared to the fixed pricing tiers of Mailchimp’s Standard and Premium Plans.
