Context

When monitoring your email sequences, you may notice that the enrollment date doesn't match the actual send dates of your emails. This can cause confusion about whether your sequence is actively sending emails to enrolled contacts.

Answer

To verify if your sequence emails are being sent correctly:

1. First, verify your sequence is active - Check the toggle switch at the top right of your sequence dashboard. If the sequence is paused, no emails will be sent to any contacts in the sequence - this includes both queued Step 1 emails and subsequent steps for contacts already progressing through the sequence. All emails will show as "Queued" until you toggle the sequence back on.

2. Understand send limits - Each mailbox has a daily send limit of 25 emails to protect deliverability. If you have multiple contacts queued, they will send gradually over time based on available mailbox capacity. With limited mailboxes, it may take days or weeks to work through a large queue of enrolled contacts.

3. Check if your sequence has been edited after enrollments began - If you've made changes to your sequence (such as removing manual tasks or modifying steps) after contacts were already enrolled, those existing enrollments will remain on the old sequence version. Sequence changes only apply to new enrollments that haven't completed step 1 yet. To resolve this, duplicate the sequence with your updated steps and re‑enroll the affected contacts into the new sequence.

4. Check for email backlogs and sending schedule - If emails show as "Queued" but aren't sending at their scheduled times, click into a queued email to see the actual scheduled send date and time - this is the most reliable indicator of when your email will send. Emails will remain queued if:

   • You're outside your configured sending hours (typically 9am-4pm in your timezone) - emails will begin sending once the next sending window opens

   • There's an inbox backlog causing delays

   When emails are enrolled during active send windows, they typically send within a few minutes, subject to mailbox capacity and queue position. However, there's intentional 2-4 minute staggering between sends to protect deliverability - this is not a bug or delay.

   Important: There is no "send now" override for automated sequence emails. Emails send based on mailbox capacity, FIFO queue order, and your configured send schedule with built-in staggering for deliverability protection.

5. Manual Email task completion requirements - If a step in your sequence is a Manual Email task, the email will remain in “Queued” status without a scheduled send time until the manual task is fully completed for each contact. Approving the task is not sufficient; you must complete the manual email action to actually queue the message for sending. To verify, navigate to Outbox → Scheduled and open the queued email; if no concrete scheduled send time is present, the manual task needs to be completed.

6. Navigate to your sequence dashboard

7. Look for the "Enrollment Date" column - this shows when contacts were added to the sequence

8. Click into individual enrollments to see the actual send dates for each step

Important: The enrollment date is different from email send dates. Each step in your sequence will send according to the timing settings you've configured, which may be days or weeks after the initial enrollment date.

Note: If you discover a backlog is causing delays, you can:

1. Reassign enrollments to mailboxes with available capacity by checking Dashboard → Health → Email Backlog to identify which mailboxes have remaining daily send capacity, then reassign your enrollment to a mailbox with lower backlog numbers

2. Temporarily pause lower-priority sequences using the same mailbox to free up capacity for urgent sends

Additional Backlog Management Strategies

• Dedicate mailboxes to priority sequences - Edit the routing settings in your high‑priority sequence to use one or more mailboxes exclusively, preventing other sequences from competing for those sending slots.

• Add more mailboxes - Distribute sends across additional mailboxes to increase your daily throughput, since each mailbox can send approximately 25 emails per day.

• Unenroll lower‑priority contacts - Remove contacts from lower‑priority sequences to free up sending capacity for critical emails.

• Use specific reassignment navigation - Access Dashboard → Leading → Email Backlog → Reassign Sequence Enrollments for more granular control over enrollment distribution.

Note that the backlog metrics (such as "Emails Added to Backlog") update on a rolling basis as plays fire and sequence steps trigger throughout the day, so the numbers represent a real-time snapshot rather than a fixed daily total.

Note: The backlog metric includes blocked emails (such as enrollments missing required template variables like company name), which can make the backlog appear larger than actual sending delays. Blocked emails don't prevent new enrollments from sending. If your backlog includes blocked enrollments due to missing template variables, you can right-click individual enrollments and select 'Refresh' to update the variables, or use the bulk refresh feature to update multiple enrollments at once - this may unblock some emails if the missing data has since been populated.

Cross‑sequence FIFO ordering – emails are sent on a first‑in, first‑out basis across all sequences that share the same mailbox. If other sequences have emails ahead in the queue, your sequence’s emails will wait their turn regardless of when they were scheduled, even if daily send limits haven’t been reached.

Additional verification method: You can also view and export your sent email history by navigating to the Emails Sent leading dashboard. Use the 30/60/90‑day filter in the top right to select your timeframe, then click Export below the charts to download a list of all recipients who received emails from your sequences.

Note: Emails sent through Unify sequences won't appear in your Gmail Sent folder because they're sent from the separate email addresses you configured in Unify.

You can monitor your mailbox capacity and backlog by navigating to Dashboard → Health → Email Backlog to see your queue position and track daily send‑limit usage across mailboxes.

Important: If emails aren't sending despite your sequence appearing correctly configured, check if you edited the sequence after enrolling contacts. Existing enrollments don't automatically upgrade to the new sequence version, which means contacts can remain stuck on old steps (like manual tasks you've since removed). You'll need to create a new sequence and re‑enroll these contacts to get them on the updated version.
