My personal anecdote:<p>When I worked at some MSP I forwarded an email to the team lead and walked to his desk to discuss some things about that email.<p>When I asked if he saw the email from me he just showed me his Outlook littered with bazillion messages and my email wasn't even on the first page, despite the time I need to walk to his desk was minuscule - we were sitting in the adjacent rooms.<p>After seeing that and the look of despair in his eyes I asked him to allow me to look what exactly was spamming his address so hard. It turned out what the bulk of it was the automated messages from a various monitoring tools and tons and tons of CCed messages, because corporate bureaucracy and the team lead "should be in the loop", duh.<p>So I took my time to write a proposal to reorganize all that shi^W mess.<p>We had a couple of pretty big clients which we supported and we had a couple of teams in our organization supporting different roles (server/hardware, SAN, virtualization, networking etc), so I proposed the creation of a bunch of mailing lists/groups (we were using Exchange from the parent company) with an address split by the role and the client abbreviated name (2-3 letters): $role.$client@msp.tld, ie:<p>hw.CL1@msp.tld, san.CL1@msp.tld, monitoring.CL1@msp.tld etc and<p>hw.2CL@msp.tld, san.2CL@msp.tld, monitoring.2CL@msp.tld and so on.<p>Of course it took some time to implement (especially changing the addresses in the various automation tools), but after that and with the help of some pretty basic Outlook rules to sort out the messages to the corresponding folders the usual 1100+ messages per day in the team lead's Inbox dropped to less than a 100.
