Questions about switching
Can a campaign wait for someone to approve it?
Yes. When the business requires sign-off, or the person drafting asks for it, the campaign waits in the one Approvals inbox for the owner or an admin, who sends, schedules or declines it.
How is a campaign's revenue counted?
A payment is credited to the campaign the person clicked last within the attribution window. Revenue is shown in each currency it was paid in and is never converted.
Can I limit how often people hear from me?
Yes. A weekly cap and quiet hours apply to every marketing send. A send that falls inside quiet hours is scheduled for the moment they end.
Who receives a marketing campaign?
Only people who opted in on that channel and are not on the suppression list. Choosing a list picks the audience; it never grants consent.
