At Superhuman we're building the fastest email client in the world, and we pride ourselves on building and running a highly reliable service.
As part of this, we'll be upgrading our primary database at 11pm PST on Friday the 20th of March. We expect the user-visible downtime to be less than 10 minutes.
During this time Superhuman will continue to function as normal. Using offline mode it will queue up emails that you send and automatically send them when the maintenance is complete.
If you notice any unexpected problems, or have concerns, please contact firstname.lastname@example.org
