Colligo vs. Mailbutler

Mailbutler is well suited to people who predominantly use their Mac for email. It adds a rich feature set to macOS Mail's native features. Mailbutler is less useful to people who frequently process email on iOS/iPadOS. Only a limited subset of Mailbutler's functionality is available on iOS/iPadOS as Apple doesn't currently provide a way for third parties to extend the iOS/iPadOS Mail app.

• Snoozing emails for later response or followup
• Reminding me to add attachments
• Allowing time for me to cancel sending an email

• Mailbutler occasionally conflicts with other macOS Mail plug-ins. Though, in most (if not all) cases the issue tends to be with other plugins.
• The Mail app for iOS/iPadOS doesn't support plugins, making it necessary to use Mailbutler's own app to access a limited subset of the functionality on macOS/iPadOS.

Support is generally very good. Occasionally the response time is a bit slower than I'd like.

I'm not aware of any other products that provide the same functionality within the macOS Mail client. There are some third-party email apps for macOS and iOS/iPadOS that have some of Mailbutler's features, but my preference is to stay with Apple's Mail client, partially for security reasons.

• Mailbutler's effect for me personally is unquantifiable - but it really helps me stay on top of the myriad emails that pass through my inbox each day.
• I would imagine that across a larger organization, Mailbutler's impact on overall productivity has the potential to be immense!
