I mean the person I replied to asked the unanswerable question. How can we say how much memory they need in their computer 'for containers' without knowing where they want to set those sliders (and how many of them there are), and then it's not really worth asking, or it would be a question about runtime overhead or something.
Why limit it to 100 emails a day for the free plan? Makes the 3000 limit feel like a false advertisement unless you have 100 users signing up every day.
