I love how some services have trap pricing, pretty much like drug dealers of the interwebs.

Me: I would like to send e-mail to my clients.

Company: Sure bro, here, take our service, you can send emails to all your clients, just 5€ per month!

A year later

Me: I have now over thousand customers, I would like to send more emails and implement some new features.

Company: Thousand customers you say?

Me: Yeah

Company: All in our servers you say?

Me: Yeah, thanks for the great service!

Company: Sure, no problem. We can enable you additional services for 40 000€ per month, half of your liver and two of your first born babies.
