Three things to add here:

1. Our pricing reflects the quality of delivery due to being transactional only. With much higher engagement rates, our speed and delivery is superior. Customers never have to wait behind a bulk campaign.

2. Dedicated IPs are a way for ESPs to pawn responsibility onto customers instead of themselves (and get a few more bucks in the process). They only make sense if you are sending a huge volume, but we do offer dedicated IPs for free for higher volume accounts. Instead, most people use our shared IPs and benefit from the volume of great engagement to get their emails delivered to the inbox faster.

3. We're the only ones to offer an extended full content history of every message for 45 days. You can search and see the exact email sent at no cost, which comes in handy when sending so many unique messages.
