How do I configure my send schedule?

Last updated: June 30, 2026

Your send schedule controls when emails go out — which days, which hours, and how delays between steps are interpreted. Configuring it correctly is the difference between a sequence that lands in inboxes during business hours and one that fires at 3am.

Where to configure

Send schedules are configured at the sequence level:

  1. Open the sequence.

  2. Click Settings → Send Schedule.

Workspace-level defaults can be configured at Settings → Organization → Sequences → Send Schedules — these apply to new sequences unless overridden.

What you can configure

Send days

Pick which days emails are allowed to send (sendDays field on the schedule). Typical configurations:

  • Business days only (Mon–Fri) — the default for B2B outreach.

  • Custom weekday pattern — e.g., Mon/Tue/Thu only.

Emails scheduled on a disallowed day wait until the next allowed day.

Time zone

The schedule has a single timeZone field that determines how send times are interpreted. Sends are scheduled in this time zone.

Skip US holidays

The skipUsHolidays setting (when enabled) automatically pauses sends on observed US federal holidays. Useful if your team operates on a US calendar.

Excluded dates

Add specific dates when no emails should send (excludedDates). Use this for company-wide blackout periods, events, or any one-off date you want to skip.

Time windows

Pick the hours emails can send within each allowed day. Outside the window, emails wait until the window opens.

Multi-region campaigns

Unify's schedule applies a single time zone per schedule. To target contacts in different regions in their local time, the common pattern is to create one sequence per region with its own schedule (and own time zone). Use Play routing to send each contact to the right regional sequence.

Sending limits per mailbox

Beyond the schedule, each mailbox has a daily send limit. New mailboxes start lower and ramp up as they warm; once warmed, you can raise a mailbox's daily limit up to 150 emails/day. This applies to all mailbox types, including Unify-managed mailboxes and inboxes you connect yourself. Your limit isn't raised automatically — set the daily max you want (up to 150) in Settings → Mailboxes. Once a mailbox hits its limit, additional sends from that mailbox queue until the next day's window opens.

To increase capacity:

  • Raise each mailbox's daily limit (up to 150) in its send settings — increase gradually to protect deliverability.

  • Connect additional mailboxes and let Unify route sends across them. Your total capacity is the number of active mailboxes multiplied by each mailbox's daily limit.

  • See How the send queue and email backlog work for queue management and reassigning queued emails.

Pausing sends for hard stop dates

If you need to halt all sends after a specific date (e.g., after an event concludes), pause the sequence rather than relying on the schedule:

  1. Open the sequence.

  2. Click the Pause toggle at the top.

  3. No new sends fire until you resume.

Paused sequences will still queue new enrollments — they just don't process queued sends until you resume.

Manual sequence enrollment scheduling

When you manually enroll a contact (from their record, from a List, or from a search), the sequence's send schedule still applies. The contact is queued for the next available send slot within the schedule.

This is why a manually enrolled contact may not receive their first email immediately — even though you triggered enrollment now, the schedule controls when the actual send happens.

To send immediately regardless of schedule: you'd need to temporarily widen the schedule or send manually outside the sequence.

When the schedule isn't behaving as expected

A few things to check:

  • Is the schedule published? Edits to the schedule are draft until you publish.

  • Is the mailbox at its daily send cap? Queued sends mean capacity is full, not that the schedule is broken.

  • Did you check excluded dates? A configured excluded date will halt sends on that day.

  • Is skipUsHolidays on? That can stop sends on holidays even if the day is otherwise in your allowed sendDays.
