I am running a number of different websites - some very active, some less so - and am about to set up another 20+. My problem is organising email correspondence.

My thunderbird folders are massive!. I have just one email account I check for each website, but 100's of folders within each one. I feel I am losing control and just wondered how other people cope.

I need immediate notification of some arrivals (notably, sales alerts & voicemails from my shops) so I'd like to keep them on my desktop. I'm wondering about using webmail for some of the less time-sensitive stuff.

I am about to setup some projects with a partner and we'd like to 'share' all correspondence.

Does anyone have a magic solution??

.. and apologies if this is the wrong forum, couldn't see a better fit
