Lunacal.ai vs. Mixmax

Lunacal.ai is an appointment scheduling and booking platform for businesses of all sizes. It helps you publish a professional online booking flow where clients can choose a service, pick a time, pay (if needed), and get confirmed automatically, without phone tag, DMs, or endless back-and-forth. Lunacal covers the fundamentals of modern scheduling software: flexible availability rules, time zone handling, buffer times, minimum notice, booking limits, and multiple event types.

Mixmax works inside Gmail so nothing falls through the cracks. Founded in 2014, it's used by people who handle their own outreach — founders, agency owners, recruiters, consultants, fundraisers and small business owners — and by the teams they work with. When you send an email, Mixmax keeps track of it. You can see when someone opens it or clicks a link. If they don't reply, Mixmax reminds you, or sends your next email for you. By default, follow-ups stop the moment the person writes back, so nobody gets another nudge after they've answered.
