Apple Mail

“Apple mail has excellent search, there are filters, it indexes file content and is done locally so it's very fast.”

“I did however have plenty of issues with search when syncing my work Outlook email via Mail.app”

“Unfortunately it doesn’t sync properly with Gmail.”

“because of the OS integration, clean UI, well-designed interactions, and decent support”

“If I type ‘repor’ in Apple mail, It will show me all report before I even type enter.”

“works well and is probably better integrated and has a better UI than Thunderbird”

“the only thing it doesn't do is shared inboxes with Microsoft Office accounts”

“crawled back to mail.app + Calendar.app on MacOS simply for how native it feels”

“Mail is the one app I care most about and it's been broken in different ways since Catalina”

“macOS mail application used to receive RSS news feeds. It couldn't be simpler for your mom than that.”

“Selecting and moving a single message can take over a second, even with animations disabled.”

“Apple Mail Search - you can filter by nearly every aspect, even between dates”

“It will disclose your Apple account address even when you received the email on a different account”

“still has an Apple Account email address disclosure vulnerability, though this requires the user to reply to a maliciously crafted email”

“doesn't change your Sent From address from the just-generated Hide My Email address to your default with no warning or rationale”

“it is fiddly and idiot proof to a fault, but provided you don't have an exotic setup”

“Mail.app's search is completely and utterly broken in my experience on Macs and on iPhones.”

“The Apple Mail client works very well with Gmail.”

“The macOS Mail.app is fast reliable in my opinion”

“Mail.app is one of the buggiest pieces of software I have ever used.”

“my local mail app (macOS's in my case) just works”

“And a great email client at that. Both iOS and macOS's. I can't imagine trading it for some web UI.”

“Calendar, Mail and Finder are all slow, dumbed down and only very superficially customizable.”

“My favorite clients are Apple Mail/Calendar for their simplicity and being local-first clients”

“Mail is more turnkey (1-click pairs with MS Exchange)”

“it works well offline or with low bandwidth networks”

“Mail search works flawlessly for me with Gmail and Outlook.”

“The search has been a disaster in Mac Mail well over a decade.”

“for me and people i know it works better than gmail”

“iOS has a persistent issue of not fetching new mails, even from iCloud”

“I can report it works fine, needed it to pull up 13 year old emails for me a couple months ago.”

“There's other bits in Mail that are flaky with Gmail compared to standard IMAP mail providers”

“Search on iOS Mail is… what is it doing? I can see the e-mail right there, but Mail can’t find it.”

“it's the easiest action that the (now long-established) WIMP user interface offers”

“The app. With MS365 I get terrible search results.”

“Did I ever have to hack anything together to make this happen so smoothly for so long? Also no.”

“my mail flow on my Mac, using the native client, is effectively unchanged for 20 years”

“The only annoyance is iyt doesn't seem that you can break multiple icloud-hosted mailboxes out into their own GUI mailboxes”

“Mail.app simultaneously just works and gets out of my way”

“I really appreciate that, and Apple does some minor changes to Mail app but generally they follow "if it ain't broke don't fix it" motto”
