How do the free trial and 35% off the first 3 months work?

On self-serve plans try it free for 10 days, then get 35% off the first 3 months. The trial opens a third of the plan's monthly quota and an e-mail arrives 2 days before it ends. The discount applies automatically on monthly billing, no promo code needed; the list price applies from payment 4. Reporting plans have the 10 day trial and 25% off the first 3 months. Enterprise plans get a free setup call instead of a trial, plus 35% off the first 3 months. Yearly billing gets 20% off instead of the launch discount.
