Configuring email send schedule

You can customize your Sequence settings here
How many emails can we send per day?

Unify's managed deliverability mailboxes are limited to 25 emails per mailbox per day and this limit cannot be increased. Customer‑owned Gmail mailboxes (connected via Google Workspace) also start at 25 emails per day, but you can request an increase up to 65 emails per day by contacting support. This maximum applies to each individual mailbox, including any email addresses you've connected through the Google Workspace integration or created with Unify's managed deliverability. If you connect your own custom domain (such as .ai, .com, or other domains), you can send more than 25 emails per day. We recommend staying thoughtful with your copy and not exceeding 65 emails per inbox per day for optimal deliverability. Note that manual one-off emails sent directly from contact records do not count toward the automated sequence send limit, providing a workaround when you need to send additional emails beyond your daily automated capacity.

Daily email limits in Unify operate on a rolling 24‑hour window rather than resetting at midnight. This means your sending capacity resets exactly 24 hours after each email is sent, not at the start of each calendar day. Understanding this timing helps you plan send schedules and set expectations for when additional capacity becomes available.

For Unify's managed deliverability Gmail mailboxes the limit cannot be increased, but for customer‑owned Gmail mailboxes you can request an increase to 65 emails per day; you can still decrease the daily max in the email settings page here.

By default, Unify will send emails on business days (Monday - Friday) from 9:00 AM - 4:00 PM PT. Emails are staggered by 2 minutes throughout the day. This frequency slightly fluctuates to emulate natural, human sending patterns. You can customize the time zone, send schedule, and days you'd like to send emails on in the settings here.

Delay Counting vs. Send Days: Delays between sequence steps are counted in calendar days (including weekends and holidays), but emails only send on your configured business days. For example, if Email 1 sends on Friday morning with a 1‑day delay before Email 2, the second email is “due” on Saturday but will actually be queued to send on Monday morning within your configured send window. This means that weekend delays don’t extend your sequence timeline—they simply shift the actual send date to the next available business day. Understanding this helps you set accurate expectations for sequence timing and avoid confusion when follow‑up emails don’t send immediately after the delay period expires on non‑business days.

Note that if you enroll contacts late in your sending window, there may not be enough time to send all emails before the cutoff, and those emails will be queued for next available sending day.

The system prioritizes natural sending patterns over attempting to push emails at the last minute. Even if a few hours remain before your send‑window cutoff, emails may be queued for the following morning to keep distribution even throughout the day.

Best practice: enroll contacts earlier in the configured send window to improve the chance of same‑day delivery.

Do emails send on the holidays?

By default, emails will not be sent on US holidays such as New Year's Day, MLK Jr. Day, Presidents Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, Christmas. You can customize the settings for sending on holidays here.

If new contacts are enrolled in your plays during this time, we will schedule those emails to go out after the holidays.

Can I set a hard stop date for my sequences?

Unify does not currently support automatically pausing sequences on a specific future date. If you need to stop emails from sending after a certain date (for example, when running event‑based campaigns or time‑sensitive promotions), you must manually pause the sequence at your desired cutoff point.

1. Go to the Sequences page and click into the sequence you want to pause

2. In the sequence dashboard (top‑right), toggle the status to “Paused”

3. If you don’t see the toggle, exit edit mode to view the main sequence dashboard

When a sequence is paused, no emails will be sent, including those already queued. Contacts remain enrolled in the sequence—pausing does not unenroll them. When you resume the sequence by toggling it back to active, previously queued emails are automatically rescheduled to the next available time within your sending schedule. If you also want to stop new contacts from entering the sequence, pause the associated Play(s) so new enrollments don’t occur while the sequence is paused.

This prevents any new emails from being sent while keeping existing enrollments intact. You can resume the sequence later by toggling it back to active. Plan to pause your sequences before your cutoff date to ensure no emails are sent beyond your intended timeframe.

What does email open tracking do?

Email open tracking uses a tracking pixel to monitor when emails are opened. Please note that enabling email open tracking could impact deliverability. If you notice that more messages are landing in Spam, consider toggling this setting "off."

Understanding Email Analytics Discrepancies

When reviewing your email performance metrics, you may notice clicks recorded without corresponding opens in your analytics. This occurs because email opens and clicks are tracked through different mechanisms:

• Opens are tracked via tracking pixels that can be blocked by email clients, privacy settings, or image blocking

• Clicks are tracked independently when links point to domains with Unify tracking installed

This means a recipient can view and click your email without the open being recorded, resulting in seemingly impossible analytics where clicks exceed opens. This is normal behavior and doesn't indicate a tracking error - it simply reflects the limitations of pixel-based open tracking versus direct link click tracking.

Note: High click counts without corresponding opens may be caused by security scanners that automatically click links to check for malicious content. These automated clicks are not genuine engagement and should be considered when evaluating sequence performance.

Re-enrollment Rules

You may wish to adjust your re-enrollment settings if you plan to re-enroll contacts who were previously enrolled in a Sequence. Common reasons for re-enrolling contacts include:

Important: When contacts are re‑enrolled into a sequence, they resume at their next step in the sequence, not from the beginning. If you need a contact to restart from step 1, you must manually unenroll them and then enroll them as a new contact.

• Updating or changing the Sequence copy

• Re-enrolling contacts who were previously excluded

• Re-enrolling contacts after a specific period has elapsed

• Re-enrolling contacts who were accidentally unenrolled (note that they will resume at their next step, not restart from the beginning)

To allow people to be re‑enrolled into the same Sequence, toggle "Allow re-enrollment into the same Sequence" on

The re‑enrollment settings only apply to contacts who were previously enrolled in a sequence. If a contact was never enrolled because they met exclusion criteria at enrollment time, they will automatically become eligible for enrollment once they no longer meet those criteria—no re‑enrollment settings need to be enabled. The “Allow re‑enrollment into the same Sequence” toggle is only necessary when you want to re‑enroll contacts who were previously enrolled and have since completed or been unenrolled from that specific sequence.

Exclusion Criteria and Automatic Unenrollment

Unify distinguishes between two types of exclusion criteria:

• Entry-level exclusions: Prevent contacts from being enrolled in a sequence if they meet certain criteria at the time of enrollment

• Exit-level exclusions: Can automatically remove contacts from active sequences when their status changes mid-sequence

By default, contacts will continue receiving sequence emails even if their exclusion criteria change after enrollment (for example, if an opportunity is opened for their account). To automatically unenroll contacts when their status changes, you must enable the "Automatically unenroll from sequence" toggle in your sequence settings.

Allow 15–45 minutes for exclusion changes to propagate through the system before expecting new enrollments to occur.

Common use cases for enabling automatic unenrollment include:

• Removing contacts when they become opportunities

• Unenrolling contacts when deals are marked as closed-won

• Stopping sequences when contacts reach certain lifecycle stages

Max Enrollments Per Company

The “Max enrollments per company” setting enforces a global, count‑based limit on how many contacts from the same company can be enrolled across all sequences simultaneously. This limit does not consider CRM lifecycle stage, deal status, or active conversations—it only counts the number of contacts from that company currently enrolled in any sequence.

To prevent outreach when there’s an active deal or conversation, use company‑level exclusions driven by your CRM deal/opportunity fields (such as open opportunity or specific deal stages) instead of relying on the max enrollments setting. Enable the exclusion’s “Exclude from Sequences” toggle to block new enrollments and automatically unenroll active contacts when the condition becomes true. You can optionally combine this with “Max enrollments per company = 1” to further limit parallel outreach, but the exclusion criteria should be the primary mechanism for suppressing enrollment based on actual deal activity.

Important Limitations and Considerations

Maximizing Daily Send Volume with Manual Tasks

Both manual and automated emails count toward your daily send limit. If your sequences include manual tasks (like personalized first emails), those tasks must be completed before the sequence can progress to automated steps. Incomplete manual tasks will prevent your sequences from reaching full daily sending capacity, even if you have available email quota remaining.

Key strategies to maximize send volume:

• Use smart snippets and personalization to create natural variation in email copy patterns

• Re-enrolling contacts who were previously excluded

• Re-enrolling contacts after a specific period has elapsed

Advanced Email Deliverability Optimization

Content Repetition Prevention

Critical Issue: Sending repetitive email content at large volume can cause Google to flag and block your emails, even when staying within daily limits. This occurs regardless of proper infrastructure setup and can affect entire domains.

• Use smart snippets and personalization to create natural variation in email copy patterns

• Diversify messaging across sequences rather than sending identical copy

• Email providers actively monitor for repetitive content patterns, so variation is essential for maintaining deliverability

Spam Recovery Techniques

Inbox Training Method: If recipients report that your emails are landing in spam, ask them to move those emails from spam to their inbox. This helps train their email system to recognize future emails from your sequences as legitimate and can significantly improve deliverability over time.

• Monitor spam folder delivery through recipient feedback

• Proactively request spam-to-inbox moves when deliverability issues are identified

• Track improvement patterns after implementing inbox training

Advanced Monitoring

• Content Pattern Analysis: Pay special attention to content repetition patterns, as this is a primary cause of email blocking by providers like Google

• Recipient Feedback Loops: Establish communication channels with key recipients to identify deliverability issues early

• Domain-Level Monitoring: Track deliverability across entire domains, not just individual sequences

Mailbox Reassignment Impact

Be cautious when reassigning mailboxes for enrollments that have queued emails. When you reassign a mailbox for an enrollment, the system creates an entirely new enrollment and cancels any previously queued manual emails. This means you'll need to re-queue those emails after the reassignment. To avoid this issue, complete mailbox assignments before queuing emails to send.

Understanding Enrollment Status

The "Queued" status in sequences can be misleading. An enrollment may show as "Queued" even when the first manual step hasn't been completed yet. True queuing only occurs after you've completed and scheduled the initial manual email task. Check that manual steps are actually completed before expecting emails to send according to your configured schedule.

Sequence Version Upgrades

When you update a sequence step, Unify creates a new version. However, existing enrollments can be upgraded mid‑sequence when the changes are compatible. Compatible changes—such as editing email copy, adjusting delays, or adding steps after the last completed step—are applied to enrollments already in progress, affecting only steps that have not yet been sent. Incompatible changes—such as deleting steps that contacts have already passed or inserting new steps between completed steps—require resolution before publishing.

Compatible changes:

• Copy edits to email content

• Adjusting delays between steps (shortening or lengthening)

• Changes that don't delete steps someone has already passed

• Changes that don't insert new steps between completed steps

Incompatible changes:

• Deleting steps that enrollments have already passed

• Inserting new steps between completed steps

Critical limitation: If you have queued manual emails (step 1 tasks that are completed but not yet sent), upgrading the sequence will reset these tasks back to your To‑Do list, even though you already completed and scheduled them. This occurs because the system treats emails as incomplete until they actually send. To avoid re‑queuing work, wait until all queued manual emails have sent before upgrading your sequence. If you must upgrade immediately, be prepared to re‑queue any manual tasks that were reset.

Upgrading queued enrollments on Step 1

1. Open the sequence's Enrollments tab

2. Filter to contacts on Step 1

3. Select the contacts you want to upgrade

4. Choose “Upgrade to latest version”

Sequence Scheduling Variations

If you have multiple sequences running simultaneously, they may send at different times even when scheduled for the same day. This occurs when sequences are assigned to mailboxes with different backlogs - sequences using mailboxes with larger backlogs will send later as the backlog needs to clear first. You can reassign sequences to different mailboxes with smaller backlogs on the email backlog page to prioritize certain campaigns.

Configuring Mailbox Routing for Sequences

Mailbox routing determines which mailboxes will be used to send emails from your sequence. Important: Mailbox routing cannot be configured directly in the sequence settings. Instead, you must configure it through the Play Builder in the associated play.

1. Open the play in Play Builder and click into the Sequence node

2. In the Routing section, click Edit persona routing

3. Select the specific mailboxes you want to use as a group (Unify will automatically rotate across them)

4. Save and republish the play

Once configured, Unify automatically rotates email sending across the selected mailboxes in the group. This routing configuration affects sequence scheduling, backlog distribution, and send capacity as described in the sections below.

Managing Email Backlogs and Sequence Priority

If you're experiencing email backlogs where important sequences are delayed, you can use these strategies to resolve them:

Understanding Backlog Metrics: The “total emails in backlog” metric includes both queued emails and blocked emails. Blocked emails occur when enrollments cannot send due to missing template variables (such as company name not being populated for a contact). These blocked emails inflate backlog numbers but do not affect new enrollments or prevent new sequences from sending. Additionally, the “time to clear backlog” estimate can be misleading during periods of high email volume. If your backlog appears larger than expected, check for blocked enrollments in your sequences and use the bulk refresh feature (right‑click enrollments and select “Refresh template variables”) to resolve missing data and queue those emails for sending.

Unify's email queue operates on a first-in, first-out (FIFO) system, which means emails are prioritized by the time they are queued and cannot be manually reordered. The “urgent” priority tag only applies to manual email tasks in BDR queues and does not affect automated email sending order. All automated emails are sent on a first-in, first-out (FIFO) basis regardless of priority settings.

• Pause lower-priority sequences: Navigate to your sequences page and toggle lower-priority sequences to "Paused." This allows the system to recalculate send times and prioritize your critical sequences. Alternatively, you can add more mailboxes to high-priority sequences to increase their send capacity.

• Dedicate mailbox groups: Assign specific mailbox groups to different campaign types (such as warm vs. cold outreach) to ensure your most important sequences get priority sending capacity.

• Reassign sequences to less congested mailboxes: Use the email backlog page to identify mailboxes with smaller backlogs and reassign high-priority sequences to them for faster sending.

• Resolve blocked enrollments: Check your sequences for blocked enrollments caused by missing template variables. Use the bulk refresh feature to update template variables for multiple enrollments at once, which can significantly reduce your backlog count and queue previously blocked emails for sending.

These approaches help you work within the daily sending limits while ensuring your high-priority sequences aren't delayed by backlogs.

When this setting is enabled, individuals can be re‑enrolled into the same Sequence after their previous enrollment has completed. When this is toggled on, there is no need to manually unenroll users from the Sequence before re‑enrolling them.

To allow re-enrollment into Sequences, toggle "Allow re-enrollment into Sequences" on

This setting permits contacts to be enrolled in new Sequences even if they were previously part of other Sequences. However, if "Allow re-enrollment into the same Sequence" is toggled off, the system will not permit contacts to be re-enrolled into Sequences they were already enrolled in unless they are manually unenrolled first.
