Hey Josh, thanks for this post. I’ve once developed an application for a colleague and sending out huge amounts of email have been a tough challenge. Having implemented SPF records on his domain and throttling of emails, we’ve had our own share of troubles. I’m glad to know that SendGrid does this reliably and that there’s an API.

Josh good post. This is exactly why we at betaworks invested in Superfeedr. One of our companies started down the path of building this themselves and we learnt what you outline above — the basic case is simple but at scale its complex. Julien is starting to kick butt at scale. Sounds like SendGrid is as well.

Completely agree with that post.

As you pointed out, us, hackers can always build what we need (and it's the beauty of the internet), however, when we want to "get serious", we have to rely on existing bricks and stop "re-inventing the wheel". To that extent, I think that building "brick" services that can be integrated in any app makes a lot of sense.

I also fully agree with the important of the IP. Of course, for feeds, (as for emails, I'm sure) there are a lot of other issues, but eventually, the "reputation" of a specific one is key to our business too.

And of course, thanks a lot Josh for the shout-out and the feedback. We're working hard to have people like you happy, and it's a pleasure!

Eloquent post Josh. Well summarized. I tried to capture more of the thought at http://one.valeski.org/2009/11/ip-address-brokers… , but your post makes the point much better. Psyched this thought is crystallizing.

Josh, thanks for the mention. As you have described, the IP reputation of a mail server plays a huge role in ISPs determining whether to send emails to the Inbox or the Junk folder. As a result, we encourage users to get their own IPs so that the good reputation of senders is not shared or affected by the reputation of bad senders. With the wider adoption of DKIM, ISPs will start paying closer attention to the domain reputation but the IP address will always play a role.
