Why did you guys choose for a 'Pro' plan instead of pay what you use?
I have a small webdev agency with 25 clients, who together send more than 100 mails a day. Currently I use a managed VPS for that, but I want to move to something that is fully managed, scalable and has a great API.
Not to bash on the 'Pro' plan. Just curious on why, and I hope you guys offer 'pay what you use' in the future. The service looks promising.
