How to set send windows and time zones

Send windows are set per connected account. Open the account under Channels, choose the Schedule tab and switch on Restrict to active hours. Pick the days, a start time, an end time and a time zone. Outside those hours the agent does not send.

Before you start

A schedule belongs to a channel account, such as one LinkedIn account or one mailbox. It is not a campaign setting.
Decide the hours your audience is at work, and the time zone you want the hours read in.

Steps

1
Step 1
Open the account
Go to Channels, choose the channel and open the account's drawer.
2
Step 2
Open Schedule
Choose the Schedule tab. For an email account the same settings sit in the active hours section.
3
Step 3
Switch it on
Turn on Restrict to active hours.
4
Step 4
Pick days and hours
Choose the days with the Mon to Sun chips and set Start time and End time. You can use the same hours every day or set custom hours for each day.
5
Step 5
Pick the time zone
Choose the Timezone. The default is your browser's time zone.
6
Step 6
Decide on replies
Optionally allow replies on days off so the agent can answer incoming messages when sends are paused.

What happens next

The agent sends only inside the window. A message due outside it waits for the next one.

Good to know

When the switch is off, a quiet window applies: no sending between 01:00 and 08:00 local time.
The starting values on the form are Monday to Friday, 09:00 to 18:00.
On LinkedIn, the Limits tab has its own sleep setting. Off means the account's time zone is detected and it sleeps from 1 AM to 8 AM. The custom fields are labelled CET.
The screen says hours are matched to the leads' working day. Check the first sends if lead local time matters to you.

Common questions

Is the schedule per campaign?

No. It is per channel account. Two campaigns that use the same account share its schedule.

Do replies stop outside the window?

Only if you leave replies on days off switched off. Use that option if you want fast answers at any time.

What is the default window?

Without a schedule, 01:00 to 08:00 local time is quiet. With the schedule on, the form starts at 09:00 to 18:00, Monday to Friday.
