Upload to Dropbox from an Email

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.

With Dropbox, you can save attachments in emails directly into Dropbox using your unique Dropbox email address created using Zapier. Save your tickets, photos, weekly automated reports, or anything you receive in an email, to Dropbox, and access them from anywhere. Note: Zapier can send files to Dropbox up to 100MB per file.

Set your Dropbox email address using Zapier

Emails can be saved to Dropbox using Zapier. Set up a Zapier zap, with your Email by Zapier Inbound Email as the trigger and Dropbox as the action app. Click "Use this Zap" and enter in your custom email address when prompted. It will look something like this: custom.1abcd@zapiermail.com. Copy this to your clipboard.

In Postbox, send a sample email to the custom email address created. After that sample is created, click "Continue".

Next, select the folder in Dropbox to save files sent to the email address you just created. You can now save email files to that Dropbox folder. You can create new zaps and new email addresses to save to other Dropbox folders.

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 Dropbox/Zapier email address.

Nesting Quick Posts

Quick Posts can be nested by including "Parent Menu::" before the Direct Post name. For example, say you have the following Dropbox folders:

  • Photos
  • Tickets
  • Reports

When setting up the Quick Posts for each folder, you can then name them:

  • Dropbox::Photos
  • Dropbox::Tickets
  • Dropbox::Reports

When you access your Quick Posts, those three options will then appear under the parent menu "Dropbox". You can select one of these options under the parent menu to send the attachment to a specific folder.

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 "Photographer" with "Photos" in the subject line to your "Photos" folder.

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.
