Automatically deliver each email at the moment your contact is most likely to open it — no guesswork required.
What You'll Learn
AI Schedule uses send-time optimization to analyze each contact's historical engagement and automatically schedule delivery inside a window you define. This article explains how to use AI Schedule to boost your opens, clicks, and replies with zero extra work.
AI Schedule lives alongside your existing send options in Conversations, making it easy to switch between Send Now, Send Later, and AI-optimized delivery while composing emails.
AI Schedule uses engagement intelligence to deliver each email when a contact is most likely to notice, open, and respond. Instead of picking an exact time yourself, you choose a time window and the platform's AI selects the optimal send time within that window based on the contact's historical behavior.
If there isn't enough data for a recipient, the message is sent immediately to avoid delays.

2Key Benefits of AI Schedule
Understanding the practical advantages helps you decide when to rely on AI Schedule versus standard scheduling.
Benefit 1
Higher Engagement
Timing is selected from predicted high-engagement moments within the window you choose, increasing the likelihood your email gets noticed.
Benefit 2
Per-Recipient Optimization
Delivery timing is tailored for each recipient individually when sufficient behavioral data exists — no one-size-fits-all scheduling.
Benefit 3
Hands-Off Efficiency
The AI chooses the send time so you don't need to calculate time zones or research optimal send hours for each segment.
Benefit 4
Less List Fatigue
Individualized timing spreads send volume naturally, reducing the "email blast" effect and lowering the risk of spam complaints.
3How AI Schedule Works
Here's a quick mental model of the decision process so you understand what happens behind the scenes after you click send.
Step 1
You choose a time window
For example, next 12 hours, 48 hours, or 72 hours.
Step 2
AI analyzes historical engagement
The system reviews the recipient's historical open and reply patterns to identify when they tend to be most active.
Step 3
AI picks the best time within your window
From the predicted high-engagement moments, the AI selects the optimal delivery time that falls inside your chosen window.
Step 4
Email is scheduled automatically
No further action needed — the email is queued for delivery at the optimized time.
Fallback
Insufficient data? Sent immediately.
If there isn't enough engagement history for a recipient, the message is sent right away so your window is never missed.
4Important Limitations of AI Schedule
Important
After you confirm Send with AI Optimization, the message cannot be deleted or rescheduled. Make sure your email is final before confirming.
Email Provider Requirement
AI Schedule is only available for sub-accounts using LC Email or Mailgun as their email provider.
2-Way Sync Not Supported
AI Schedule is not supported for accounts with 2-way sync enabled, even if they use LC Email or Mailgun.
5Choosing an Optimization Window
The window balances personalization and speed. Larger windows give the AI more flexibility to find a high-engagement moment, while smaller windows prioritize faster delivery.
Short Window (e.g. 12h)
Prioritize Speed
Best for time-sensitive updates or announcements where you need delivery soon with moderate optimization.
Medium Window (e.g. 48h) — Recommended
Balanced Approach
The recommended balance of timing precision and delivery speed for most use cases.
Long Window (e.g. 72h)
Maximum Optimization
Best when timeliness is less critical, such as newsletters or long-running nurture sequences.
Tip
Consider your campaign goals. Time-sensitive updates may benefit from a shorter window, whereas newsletters or nurture emails often perform better with a longer window.

Q: What happens if there isn't enough engagement data for a recipient?
The email is sent immediately so you don't miss your selected window. Engagement data builds over time as contacts interact with future emails.
Q: Is AI Schedule available for SMS?
Currently, it's email-only. AI Schedule is not available for SMS at this time.
Q: Which email providers support AI Schedule?
