Convo, a tool perhaps best described as a real-time company message board, picked up a new trick this week: automated acknowledgements.

It’s a pretty common thing in the corporate world: you need to send something out to all of the employees at your company, but you also need to know exactly who has seen it (and, of course, who hasn’t.) Who actually got the memo? Can you say that everyone has seen some mandatory reading? Who still needs to see it?

You can try to use email read receipts, but those are hit-or-miss — particularly as many email clients disable them by default nowadays. You can make everyone sign a form saying they’ve seen the document in question, but that’s a pain in the butt. When all you need is a list that says “Yep, these employees have all seen this blurb of text” so you can meet some new compliance requirement, it shouldn’t be complicated.

Convo’s new tool makes it pretty easy: write your post like any other, but check the “Recipients must acknowledge to view” box before sending it out.

When it pops up in your colleagues’ Convo timeline, it’ll be almost entirely blurred, save for a subject line and a prompt asking them to acknowledge the post. Once they deliberately acknowledge it, the post is de-blurred, the original poster gets an alert letting them know someone has read it, and the reader’s name moves from the “Has not seen” to the “Has seen” list.

To be clear, this isn’t a security feature; there are ways to get around the blurring without officially acknowledging it. Hell, you can just say “Hey Jim, did you already open that Convo post? Let me see it on your phone.” The point here isn’t preventing anyone in the company from seeing something, but in making sure everyone has seen something, and having an automatically generated list to fulfill any compliance requirements. If you’re using Convo’s group features correctly, it should only show up for people you intend to see it in the first place.

The feature rolled out earlier this week. It’ll be available for all Convo networks for the next month to check out, at which point they expect to limit it to Enterprise-level customers.
