When we're not the right fit: if you send millions of emails a month, Amazon SES directly or SendGrid Pro will serve you better. Our largest plan is 200,000 a month; for dedicated IPs or more volume, email us about Enterprise. And if you need Outlook or Apple Mail to connect straight to a mailbox, that is not ready yet: our inbox is for support-style mail with daily limits, and you can forward any mailbox to Outlook or Gmail meanwhile.
