Email notifications
Under Settings › Email notifications, choose which emails you get:
- Successful posts: when a post publishes to every selected platform.
- Failed posts: when one or more platforms fail.
- Destination suggestions: ideas for other platforms in success emails.
Account reconnection alerts are always sent, because they keep your workflows running. Changes save automatically.
Timezone
PostOnce uses your browser’s timezone for scheduled posts and the calendar. Workflow schedules have their own Timezone setting under Settings › Publish, so a workflow can publish in another timezone.
Change your account email
Changing the email on your account isn’t available in the app yet. Email support@postonce.to from your current address with the new one.
Sign out
Click your name at the bottom of the sidebar, then Logout.
