Stop Paying the "Success Tax"

The Problem with Mailchimp
Why pay for data storage?
In 2024, data storage is effectively free. Mailchimp's pricing model was built 20 years ago when storage was expensive. They charge you a "Success Tax" — the more your list grows, the more they punish you.

“I felt cheated by Mailchimp. I run a seasonal event and have a list of 40,000 attendees. Mailchimp wanted $300/month even in the months I sent ZERO emails. I switched here, uploaded my list for free, and now I just buy a €40 Top Up when I need to send invites. It saved me $3,000 this year.”
Why are you still paying "Rent" on your own list?
Most email platforms charge you to store your contacts. We think that’s wrong. Your data is yours.
We only charge you when you deliver value to your audience.
