The Verdict
Fantastical is built for apple users and professionals, with a focus on natural-language and calendar-sets. Proton Mail targets privacy conscious users and journalists and leads with encryption and zero-access-architecture.
Pricing is close: Proton Mail starts at $3.99/mo versus $6.75/mo for Fantastical — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
