When composing a new email, you can set the traditional email settings (recipients, body format, etc.). In the bottom left-hand corner, you will notice an eye-like icon. This toggle allows you to set the view-count trackability of the email.
Note: If the icon appears as an eye, the email will be tracked. If the icon appears as an eye with a slash "/" on top of it, the email will not be tracked.
AMPED automatically syncs your emails every 60 seconds. You can also manually sync your connected email in your User Preferences. AMPED syncs up to your most recent 5000 emails across all inboxes.
