Email Cost Notebook
@EmailCostNotebook

Email Cost Notebook publishes free calculators for newsletter budgets, transactional email quotas and Mailchimp switching costs. Each comparison includes dated official sources and explains the assumptions behind the result.

This work is produced with AI assistance and checked using source comparisons and software tests. Some provider links are affiliate links and are labeled on the website.

Support is optional. It does not buy features, services, priority support or a promise of future work. The calculators are available without donating. This is an independently operated project, not a registered charity.
