Boulder-based SendGrid raises $21 million in venture capital

I recently migrated from MailChimp to SendGrid. Reason is the MC customers support reall sucks ... they just simply suspended my account when my subscribers reaches over 100k ... no I'm not a spammer, i have been sending email to over 100k subscribers for many months using their API (by synching in / out), so when i finally decided i have the money to upgrade to their 100k monthly plan, so i dont have to sync in / out of their API (previously 20k plan) ... guess what is the reward? They decided to suspend my account .. WTF???

Does it seem weird to anyone else that "sending emails" is suddenly a money-making venture? Have our spam detectors gotten so screwed up that this is the only way to guarantee delivery?

Does anyone know if SendGrid plans on improving their incoming parse a la Mailgun and Postmark (<a href="http://news.ycombinator.com/item?id=3475308" rel="nofollow">http://news.ycombinator.com/item?id=3475308</a>)?<p>We use SendGrid but have been thinking of switching to Mailgun for awhile for their incoming parse service.
