Every year, I reinstall all of my iOS third party mail apps and hold a battle royale to see which one will remain on my iPhone for the next year.
iOS Mail: where email goes to die. still no real share sheet. Must use some pretend “print and share pdf” to get a crippled share sheet. URL Schemes do work so you can initiate mail from Drafts which gives you access to Textexpander Fill-In Snippets. However, when you are answering email, you are limited to just the Textexpander Keyboard. Regularly updated.
Outlook: sucks slightly less than Mail. but still garbage as it has no real share sheet. Must also use some pretend “print and share pdf” to get a crippled share sheet. URL Schemes do work so you can initiate mail from Drafts which gives you access to Textexpander Fill-In Snippets. However, when you are answering email, you are limited to just the Textexpander Keyboard. Regularly updated.
Spark: If you ignore the Calendar and Teams, its not a bad little personal e-mail app. It has a nice share sheet and integrates with Omnifocus nicely. URL Schemes do work so you can initiate mail from Drafts which gives you access to Textexpander Fill-In Snippets. However, when you are answering email, you are limited to just the Textexpander Keyboard. Regularly updated.
Dispatch: No Exchange/Office365 or POP support. Nice share sheet and service menu. Integrates nicely with Omnifocus and Fantastical. Supports Textexpander Fill-In Snippets so emails can be initiated from within the app or Drafts and responding to email also gives access to Textexpander Fill-In Snippets. Native TextExpander support also allows the use of external keyboards. a Huge plus. It has not been updated in 2 years.
Airmail: Did Not Qualify: For two years the developers have refused to fix the broken plainbody URL Scheme. This is unacceptable. If an app cannot provide TextExpander support, then it at least needs to provide a working URL scheme to receive the text from Drafts. I subscribed in hopes it would spur the developers to fix this glaring issue. It did not so I canceled my subscription.
Edison: Did Not Qualify: Security Issues
The Winner: Dispatch The combination of share sheet, service integration, and TextExpander Fill-In snippets make this THE email app for power email users. Spark is a a nice runner-up but its lack of TextExpander support will keep it second fiddle.
I know the choice of email apps is personal and subjective and that the stock mail app serves most people. However my workflow is built on TextExpander and Omnifocus with a sprinkle of Fantastical. Dispatch rings all the bells and check all the boxes.
