Reports as body of email instead of attachment
Our CTO is asking me to provide a daily email report of some key metrics to our clients and internal stakeholders. I'm able to create a suitable report and email it, however his concern is the number of clicks to view the report. The belief is that the email will just go straight to trash if our clients can't see the report in the email body. For me, using gmail, I have to download the attachment first, then open it from my laptop. Two options we talked about were:
1. Use the HTML report as the body of the email rather than an attachment (surely the days of text-only email clients are gone)
2. A configurable/dynamic subject to provide some hint of what the report actually contains, e.g. the uptime for a particular service over the last 24 hours. If the subject said "100% Uptime", there is no reason to open the report, if the subject said "98% Uptime" I can open to see more detail.
Does anyone else have any ideas on how to make reports a little more effective for a somewhat apathetic audience?
