I am so tired of Mail.app constantly running at 100-200% CPU load on Yosemite! It drains my battery, makes the fans run loud, being hot, and it's just a pain...

So what are any worthy alternatives for Mail.app? I love the GUI and search. But having only 2 hours of battery time when having Mail open completely ruins it.

I have looked on the new Outlook, and it actually looks pretty neat. Anyone who uses that?

The only thing I do, is writing mails, sending some attachments once in a while.

I have the following mail accounts in Mail.app:

- 2 IMAP accounts
- 2 Exchange accounts
- 1 Gmail account

So it should be able to work with all of those (preferably with a unified inbox).
 
Airmail 2.0. Using it with Microsoft Exchange Online via EWS. So far I am quite satisfied with it, but I am not using it sophisticatedly so it is possible that it is just because I haven't triggered the bugs underneath... Also not sure about how well it handles Gmail, as it seems the App Store is currently flooded with low ratings.
;)
 
Used to use Postbox, use Outlook for work, have settled on Airmail (now v2), for all accounts, superb UI, fast and stable with minimal resources.

Only thing is you will need to hack the sound it plays when you delete mail (turning off ALL sound is in its prefs but that disables the mail arriving sound too...). I just deleted trash.wav (in Resources), and duplicated and renamed archive.wav to trash.wav - much better unintrusive sound IMHO.

...this is obviously not normal.

Why not solve your Mail issue ?

Mail under Yosemite runs away sometimes for me too, no rhyme or reason that I could pin down. Airmail 2 also has a great colourful UI, non of the flat dull greyness that Mail gives....
 
Thunderbird for me, has close to a million messages from 15 years stored, about 10 email accounts, no issues accessing it from OS X or windows simultaneously.

I used Thunderbird for years but when development ceased I moved to Postbox. You shouldn't have any issues accessing IMAP mail servers with multiple clients though...
 
Thanks for the replies! I'm going to test Airmail over the next few days to see if it suits me :)
 
There's postbox, outlook and thunderbird. Of the three, I prefer Postbox on OSX, Outlook on Windows and I don't like Thunderbird :)
 
I have the same question - what about Postbox? It was included in the latest MacHeist bundle (great deal btw, today's the last day I think) and I installed and began playing with it.

I'm on metered internet, and want something that won't eat up bandwidth all the time. Would be great if I could set downloads to happen overnight during the free zone. Mail seems to be always talking to the servers and I hoped that Postbox would be better. Is it?

Is Postbox easier on the CPU? Mail seems to be a hog there, too.
 
Wanting a different mail app is fair enough, CPU going up to 100-200% is not normal though. I would really look to sort that first before switching apps. Check out the log files and see what errors are occurring as the processor gets stuck on something...Oh and do a permissions check, always good to do.
