Send Emails to OmniFocus Inbox
Postbox's Quick Post feature enables you to quickly set up and use send-to-service email addresses. Best of all, you can send content to the service in the background, without having to open up a compose window.
You can forward emails to your OnmiFocus Inbox or delegate actions to a partner's OmniFocus Inbox using your unique OmniFocus email address. Turn emails from your boss into your schedule for the day or forward reminders about kids activities to your spouse using OmniFocus, and get everything done. Note: OmniFocus is only available for Mac, iPad, or iPhone.
Set your OmniFocus email address
Download and log into the Omni Sync Server. Click on the "Create Address button" to generate a unique email address. The address should look something like: email@example.com.
Copy the email address to your clipboard to save as a Quick Post. When emails are sent to this email address, they will be turned into an action in your Inbox in OmniFocus. Other people can also use this email address to create actions in your Inbox.
Create your Quick Post
In Postbox, navigate to Preferences or Options > Advanced > Quick Post and then click the + button to create a new Quick Post.
Create a name for the Quick Post, then enter your OmniFocus email address.
When an email is forwarded to OmniFocus, the subject line will automatically become the Inbox item name. Any text, attachments and simple HTML in the body of the email will become the Inbox note.
Note: More complex formatting is stripped from the email.
Specify how the message should be sent
Send As Attachment is usually the best way to go since you're forwarding the original email. Services can then do the right thing with regards to images as attachments, for instance.
Send should be used when the service doesn't know how to process .eml files as attachments, like Trello or Slack. However, it does have some limitations. For example, images embedded into the message body as an IMAP URL won't show in the destination.
Send via Compose Window will bring up the Compose Window, which you can then edit before sending. This option is also the best one to use for images embedded into the message body as an IMAP URL.
Automatic email filtering or forwarding
You can also set up Postbox's email filters to automatically trigger a Quick Post when you receive an email from a specific sender or with a particular subject.
For example, you can configure Postbox to quick post any emails sent from "Your Wife" with "Gymnastics" in the subject line to your to-do list.
To set this up, go to Postbox's Tools menu > Message Filters > New, set your filter criteria, then for the action select Quick Post and then your desired Quick Post.
But note that messages are always sent As Attachment when using a filter action because, by their nature, filter actions run in the background. So be sure to select "Send as Attachment" within the editor panel for this Quick Post.
