Set sending hours, delays and daily caps
Control when messages can send and how much a campaign can use each day.

Distinguish three timing controls
The sending schedule chooses the days and time window in which a campaign can send. A follow-up delay sets the gap between sequence steps. Daily limits restrict volume at both campaign and inbox level. Review all three together: a delay ending does not override a closed sending window, and a wide window does not increase a daily cap. The public guides describe these controls but do not document the exact queue calculation or a timezone selector.
Choose the campaign’s sending window
Open the schedule settings
In your campaign, find the sending schedule settings to control when emails go out.
Expected result: The campaign’s sending schedule controls are visible.
Pick days and times
Choose the days of the week and the sending time window. Use hours appropriate to your audience and the team handling replies.
Expected result: The selected days and time window match your intended audience coverage.
Set a per-campaign daily limit
Cap how many emails the campaign sends each day. Combined with your per-inbox limits, this keeps your sending volume safe.
Expected result: The campaign daily limit is set to the intended maximum.
Respect inbox limits
Each inbox has its own daily limit, documented as 30 by default and up to 100. Sending is constrained by both the campaign cap and the inbox cap.
Expected result: The selected mailbox limit has also been reviewed.
Save and let it run
Save the schedule. Outreach DigLab distributes sending across the chosen window; the guide does not promise an exact minute for each recipient.
Expected result: The saved campaign shows the intended window and daily cap.
Place follow-up delays inside the plan
Open each follow-up step and choose its delay from the previous email. Use enough time for the first message to be read and answered. Review the sequence as a whole rather than setting every delay independently: several short gaps can produce more frequent contact than you intended. Replies automatically stop further follow-ups to that contact, so the delay is relevant only while the contact remains in the sequence.
Example operating plan
| Item | How to use it |
|---|---|
| Working days | Example: Monday to Thursday, when a teammate is available to handle replies. |
| Sending hours | Example: a morning-to-afternoon window. Confirm how the current interface interprets the times before launch. |
| Campaign daily cap | Example: 20, below a mailbox limit of 30. This is an illustrative configuration, not a recommended volume for every mailbox. |
| Follow-up delay | Example: a few days after the first message, with a useful additional detail. |
| Other campaigns | Review other activity using the same inbox instead of allocating its full capacity repeatedly. |
Diagnose a campaign that appears idle
First check whether the current time is inside the selected sending days and window. Next inspect the campaign and inbox limits and the recent activity using that mailbox. Then confirm the inbox is active and the intended contacts are available. If the timing still looks wrong, record the displayed schedule, your timezone and the observed timestamps for support. Avoid creating another campaign just because a queued message has not sent immediately.
