  12. 12. 2. Issues & workarounds across accounts Before [my colleague and I] set [Slack] up, it was really horrid, […] it would all be like, ‘Oh, I sent you an email three months ago’ or ‘I sent you a text’ or, like, ‘I’ve got this like WhatsApp chat thing’.

  18. 18. Take home message 1.  Work and personal emails are managed and retrieved differently. 2.  It’s important to consider multiple devices: emails are primarily retrieved on laptops/PCs & smartphones are rarely used for finding emails. 3.  Email retrieval is a frustrating experience. 4.  As a result, users create workarounds, i.e. using Slack or taking screenshots. ≠ ×
