It is looking likely this email is real, but I'm sure we'll get confirmation soon.
These numbers look good for Model 3 demand at this stage. A US order backlog for SR+ cars would have been built in Q1, so net new orders in Q2 will be suffering from order pull forward into Q1. The SR+ launch in Europe and Asia plus US lease launch both happened in Q2 though, so pent up demand for these options will have offset the Q1 US SR+ pull forward to some extent. It would be helpful to know the total unfulfilled order backlog.
It's hard to know what order rates look like for S/X, and to what degree they have now managed to ramp production back up. I'm sure order rate will have improved significantly from Q1, but it likely isn't yet back at the c.25k/Q target rate, and production could hold back S/X in Q2.
I expect Model 3 demand in China is starting to be held back significantly by progress with GF3. GF3 cars will be dramatically cheaper than US cars and if people are hopeful the wait may now be just 4-6 months they will be very hesitant to pay the post tariff, incentive excluded cars currently on offer.
