Tesorio users can specify windows of time within which campaign emails will be sent. This includes modifying time zones, days of the week, and hourly breakdowns. This functionality is available on the campaign setup page for both age-based campaigns and schedule-based campaigns.

Tesorio runs an "email task" once per hour. If you set up a sending schedule between 8 am and 5 pm on a given day, Tesorio will first look for and send any emails at 8 am, then again at 9 am, etc, throughout the open window period.

Following this process, any auto-approve emails that have queued up outside of the sending window (ie, overnight) will send at 8 am when your self-defined scheduling window opens and Tesorio runs its hourly email task.

If there are campaign emails that require manual approval and they get confirmed at 8:15 am, they will queue up and send at 9 am when the next hourly email task runs.

This process will repeat on an hourly basis throughout your "open window" period.

While the sending window is open, the campaign status will show as "Emails are sending". It's true that some emails may actually be waiting to send because they missed Tesorio's hourly check, but they will go out on the next check provided the sending window does not close in that time.

When the sending window is closed, the campaign status will show as "Emails are Scheduled." These emails will send the next time the window is open and Tesorio's email task runs.

There may be times when many emails are queued in the application for processing and the volume causes a delay as to when any given email is received in the end customer's inbox.

On average, processing time to send an entire queue can be between 0 and 4 hours. Please take this into account when scheduling your send windows. Also, if your account has hit its daily limit for emails, messages will remain in the queue until the following day.

When creating a new campaign, the sending time window defaults to every day of the week, at all times, and will show a status of Email Sending. Depending on any changes you make to the sending time, the Email Sending status may change.

Regardless of sending window, if an email needs to be approved, it will not be sent until after it is approved.

If an approval happens before the scheduling window, the email waits until the window opens. In the event of a volume issue, the email will send even once that window closes because it was in line to go out during a valid send period.

If approval happens after the scheduling window, the email waits until the next scheduled window (even if on a different day).

If approval happens within the scheduling window, the email is sent immediately.
