Managing Email Sequence Timing and Delays
Last updated: April 27, 2026
Understanding Email Sequence Scheduling
Unify's email sequencing feature operates on a fixed schedule to optimize deliverability. By default, emails are sent between 9 AM and 4 PM PT (Pacific Time). While this schedule cannot be customized for individual prospects or time zones, there are several ways to manage your email sequence timing effectively.
When you enroll a contact during your send window, emails are queued and typically send within a few minutes, subject to mailbox capacity. Emails are intentionally staggered by approximately 2‑4 minutes between sends to protect deliverability. Each mailbox has a limit of 25 emails per day, and if a mailbox is at or near this limit or has a backlog, emails may take longer to send and can roll into later send windows.
Adjusting Email Sequence Timing
Here are some strategies to control when your sequence emails are sent:
Configure Custom Send Schedules: You can create custom send schedules for your sequences to control allowed days, time windows, time zones, and add skip dates. This ensures emails only go out during the windows you specify; anything due outside those windows will wait until the next available send window. This is particularly useful for time‑bound campaigns or event‑based outreach.
Modify Global Send Times: If you need to change your organization's default 9 AM - 4 PM PT schedule across all sequences, contact Unify support to adjust this global setting.
Increase Delay Times: For future enrollments, you can increase the delay times between steps in your sequence. Note that delays are counted in calendar days (including weekends), but emails only send on business days. For example, if an email sends on Friday with a 1‑day delay, the next email is due on Saturday but will be queued for Monday morning within your send window. If an email is scheduled for a day outside your configured send schedule (such as a weekend day when weekends are excluded), it will remain in the queue and be sent during the next available send window on a business day per your organization's settings.
Pause and Resume Sequences: If you need to temporarily stop emails from being sent, you can pause the entire sequence. Resume it when you're ready for emails to start sending again. This approach is especially effective when you need a hard stop after a specific date, such as at the end of an event or campaign window.
Unenroll and Send Manually: For more precise control, you can unenroll prospects from the sequence and send emails manually. This is particularly useful for prospects in later stages of a sequence.
Reassign to Mailboxes with Available Capacity: If emails are delayed due to mailbox backlog, you can reassign enrollments to a different mailbox with more available capacity. Check Dashboard → Health → Email Backlog to see which mailboxes have remaining daily send capacity and smaller backlogs. Reassigning to a less congested mailbox can help emails send more quickly.
Managing Prospects in Specific Sequence Steps
If you need to adjust timing for prospects at a particular stage of your sequence:
Navigate to the sequence enrollment page.
Identify the prospects in the specific step you want to manage.
Consider unenrolling these prospects if you need to send different emails or adjust timing significantly.
For small volumes, you may choose to send manual, one-off emails instead.
Checking Email Queue Status and Timing
If you need to see when a queued email will send:
Click into the specific queued email in your sequence to view its scheduled send date and time. This reflects mailbox capacity and queue order.
Navigate to Dashboard → Health → Email Backlog to check backlog metrics per mailbox and see which mailboxes have available capacity versus high queue volumes.
Emails send in first-in-first-out (FIFO) order with 2‑4 minute staggering between sends for deliverability.
If an email remains queued longer than expected, it's typically due to the mailbox reaching its 25 emails/day limit or having a backlog of pending sends.
Important Notes
Unify does not currently support customizing send times by individual prospect or time zone.
The system doesn't allow manual changes to scheduled delivery times for individual emails within a sequence.
There may be a delay in updating sequence statuses and activity tracking. If you notice persistent issues, contact Unify support.
Each mailbox has a daily sending limit of 25 emails. When a mailbox reaches this limit or has a significant backlog, queued emails will wait for the next available send window. Check the Email Backlog dashboard to monitor mailbox capacity.
By utilizing these strategies, you can effectively manage your email sequence timing within the constraints of Unify's current system. Remember to regularly review your sequence performance and adjust your approach as needed.
