According to Qmarkets' policy, each user can decide to not getting emails at all by un-checking the relevant email types from profile page:
In addition each user can:
- Unsubscribe to the newsletter once the recipient receives the mailer (unsubscribe link at the bottom of the email)
- Unsubscribe from a campaign from the campaign header
- Unsubscribe from specific ideas or change the notification frequency from the Profile Page/Subscriptions
Under "Subscriptions" in the user profile, all of the notifications are sorted by type (Items, Campaigns).
For each type, mark the checkbox for items you want to be subscribed to. You can choose for which kind of updates to get a notification (all updates or just comments) and on what time base (hourly, daily, weekly...).
