Interesting facts about email attachments

Like it or not, sharing documents via email happens daily. Earlier this summer, we launched DokDok to help Google Apps users turn their inbox into a productive document sharing tool.

Our users are now tracking 2 million documents scattered across 10 million emails. Here are some interesting facts we learned from these.

I’m curious if you have stats on what percentage of the 2 million email attachments are actually opened?

That would be interesting stats but it’s not something we track or intend to. Email marketing systems that track opening of emails do so through small invisible images loaded when the email is read. Something similar with attachments would require a tracking callback within the document itself (if the format supports it) or replacing attachments with intermediate links (thus breaking offline support).

It’s certainly doable and if you’re tracking marketing effort (eg. pdf brochure or reports sent to large clientele), that would probably give relevant campaign metrics but it wouldn’t tell much about standard file attachments.
