Notifications use the notification bar, and show a short preview of the email.
BlueMail allows you to control the notifications method per account using Settings | Notifications | [select the account] | Push or Fetch:
- Instant Push: get instant notifications. Offered on iOS, and on Android only for accounts you signed into with Google, Microsoft or another provider sign-in page rather than a password. It is never offered for POP3 accounts, and some providers switch it off for their own servers.
- Direct Push: get instant notifications through a direct connection to your email provider. Android only, and not for POP3 accounts.
- Frequent Fetch: check for new emails periodically.
- No Push: disable push notifications, but still see emails being updated when opening the app.
- Manual: do an on-demand refresh sync only, without notifications.
Frequent Fetch, No Push and Manual are always available, and BlueMail adds the push options wherever your account can support them, so a shorter list simply reflects what your provider offers.
Instant Push also depends on BlueMail's push services being switched on, and a few providers signal that they do not accept push at all, in which case BlueMail leaves the option out rather than offering something that would never arrive.
If you choose Frequent Fetch on Android, a Fetch Interval setting appears beneath Push or Fetch for how often to check. It is not offered on iOS.
Please note that only emails arriving in the Inbox trigger a notification. Mail delivered straight to another folder, by a provider-side rule, for instance, will not notify you.
