no issue
- Mailgun makes it really difficult to find your baseUrl from their UI if you've previously sent emails on a domain
- use a dropdown with flag and region name instead to better match what you can see in their UI
refs 5fd2b7fed1
- sends `?send_email_when_published=true` query param when scheduling/publishing a post with the toggle turned on
- adds support to the posts adapter for handling the `adapterOptions` option
- updates the editor `save` task to pass through the required adapter option when a post is being published or scheduled with the toggle checked
- moves state for the email toggle into the publish menu so that we don't try to toggle the model attribute which should only be fetched from the API
- prevent `post.send_email_when_published` being sent to the API via the serializer as it's now a read-only attribute
no issue
- refactored `renderEmailPreview` into separate fetch and render functions
- grab email info from an existing email resource if it exists on the post rather than fetching a preview
- added "View email" button the the email-sent state of the newsletter settings PSM section
no issue
- changed `disabled=deliveredAction` to `disabled=mailgunError` so that it's switching on the correct property
- removed all references to the unused `deliveredAction` property
no issue
- removed unnecessary scratch value handling for a non-model property
- use [`oneWay`](https://api.emberjs.com/ember/release/functions/@ember%2Fobject%2Fcomputed/oneWay) to bind the logged in user's email address to the `testEmailAddress` property on the component - this allows for the default value to always be the logged in users email but changing the property value only changes the value on the component, not upstream on the user model
- use default two-way binding of the `<Input>` helper to avoid unnecessary boilerplate
- removed unnecessary usage of the `truncate` helper for the placeholder
