Multiple account support, calendar integration, cross-platform, smart notifications, send later, message reminders, and more. It’s also worth noting that Spark is still a great mail client even if you don’t pay for the extras – anyone who already used Spark 2.0 will find all the stuff they liked before still included in the free iteration. But if email is important to you, it could very well be worth the outlay. If you’ve lived with email as a free, fundamental part of online life for decades, it’s a big ask. After an initial 7-day trial, you’ll need to stump up $8/month (or $60/year) to continue using its full suite of features (priority email, gatekeeper, thread muting, and more).

There’s also the sticky matter of payment. If you’ve been using email for decades, accepting a completely new approach that can literally disappear emails and arrange them in an unfamiliar order can be quite a lot to get used to. One of Spark’s main issues is its very uniqueness.
