The site was built from day 1 with SEO as the primary user acquisition channel. So most of the engineering effort has been to ensure that the images are saved, all of the text is preserved, and all links are crawled to their final landing page. The last one has been especially challenging, with all kinds of tracking links, blocked crawlers, and bad HTML -- all while trying to avoid click on any unsubscribe link.
I use Skimlinks for monetization. I could rewrite the links, but for now I am just using their drop-in JS script that rewrites any monetizable links automatically. Very easy (though they take a decent cut).
I can't see myself ever using this service, so I'm interested in what makes people want to. Would you be willing to share the sort of search queries that lead people to you?
People aren't searching for the service -- they're searching for the content. It's a very long tail of keywords that brands have used across millions of emails.
