By the end of this guide, you'll know how to create multiple sending schedules within a single campaign, understand when to use multiple schedules versus separate campaigns, and configure schedules that maximize engagement by reaching prospects at optimal times.

Email timing directly impacts open and reply rates. Sending at 9 AM when your prospect is starting their day gets better results than sending at 3 PM when they're in meetings. Multiple schedules let you target different time windows throughout the day, increasing the chances your emails land when prospects are most likely to engage.

Benefits of multiple schedules:

This is especially powerful for high-volume campaigns where you want to maximize daily sends without appearing like a mass blast.

Before setting up multiple schedules:

Multiple schedules let you define multiple time windows per day when emails can be sent.

Example single schedule:

Example multiple schedules:

This gives you more precise control over when emails land in inboxes.

Step 1: Open your campaign

Go to Campaigns and select the campaign you want to edit (for example, “Re-engagement - Inactive Leads”).

Step 2: Open campaign settings

After opening the campaign, click the Sequence tab to access the sequence editor.

From the sequence editor, click the gear icon (⚙️) at the top (next to the campaign name and toggle) to open the campaign settings.

Step 3: Navigate to Schedules & launch

In the campaign Settings panel (which opens over the sequence editor), click Schedules & launch.

This is where you'll create and manage all sending schedules for the campaign.

Step 4: Set up the first schedule

In Schedules & launch, you’ll typically see an existing Default schedule under Your campaign schedules.

To create an additional schedule, click Create a new schedule. (You may also notice the Auto launch section above. This controls automatic sending to new leads, but it’s not required for creating multiple schedules.)

Step 5: Configure Schedule 1 details

The schedule editor appears inline under Your campaign schedules. Configure the fields using the same labels shown in the UI:

You’ll also see an estimate like “This schedule will reach out to X new leads per day.”

Step 6: Save the first schedule

Click Add this schedule to create Schedule 1.

Step 7: Create a second schedule

Back in Schedules & launch under Your campaign schedules, click Create a new schedule again.

Step 8: Configure Schedule 2 details

Create a second window using the same fields as Schedule 1. Example configuration:

Step 9: Save the second schedule

Click Add this schedule.

Step 10: Review both schedules

You should now see both schedules listed in Your campaign schedules (for example, “Morning sends” and “Afternoon sends”). From here, you can also click Create a new schedule again if you want to add more windows.

Step 11: How emails are distributed

When you have multiple schedules, lemlist distributes sends across all active time windows.

Example with 100 emails to send today:

The exact distribution depends on lemlist sending algorithm, your daily sending limit and how many leads are ready to send.

Step 12: Test the schedules

Launch a small batch of leads (10-20) and monitor when emails are actually sent.

Check the Leads tab to see send times and verify they fall within your configured windows.

Configuration 1: Morning and Afternoon Windows (Most Common)

Use case: B2B campaigns targeting office hours while avoiding lunch

Why it works: Emails land when prospects are at their desks and checking email (morning start and afternoon return), not during lunch break.

Configuration 2: Multiple Daily Bursts (High Volume)

Use case: High-volume campaigns that need to spread sends evenly throughout the day

Why it works: Distributes sends across four windows to avoid sending limits and appear more natural.

Configuration 3: Peak Engagement Times

Use case: Data shows your audience engages most at specific times

Why it works: Concentrates sends during proven high-engagement windows based on analytics.

Configuration 4: Weekend + Weekday Schedules

Use case: B2C campaigns targeting consumers who check email on weekends

Why it works: Covers weekdays and weekends with appropriate time windows for each.

Use multiple schedules within one campaign when:

✅ Targeting the same timezone with multiple sending windows

✅ Spreading sends throughout the day to avoid limits or spam filters

✅ Avoiding specific hours (lunch, early morning, late evening)

✅ Managing one audience with time-based distribution

Use separate campaigns when:

✅ Targeting different time zones (US East Coast vs. West Coast vs. Europe)

✅ Targeting different audience segments with different messaging

✅ Testing different sending times (A/B test: morning sends vs. afternoon sends)

✅ Managing different products or offerings

💡 Pro tip from the original article: If your leads are in different timezones, create separate campaigns for each timezone and import leads accordingly. This ensures 9 AM in New York doesn't become 6 AM in Los Angeles.

Marketing Agency Managing High-Volume Campaign

A marketing agency runs a cold outreach campaign for a SaaS client targeting 500 leads per day. Their email provider limits them to 150 sends per hour.

Challenge: Sending 500 emails in one burst (9-10 AM) would hit hourly limits and appear unnatural.

Solution: Multiple schedules

Result:

Key takeaway: Multiple schedules helped avoid technical limits and improved engagement by appearing more human and natural.

Issue: Emails are only sending during one schedule, not both

Root cause: One schedule may be filling your daily sending limit before the second schedule activates

Fix:

Issue: I'm not sure which time windows to use

Root cause: No data on when your audience engages most

Fix:

Issue: Emails are being sent outside my configured schedules

Root cause: Timezone settings may be incorrect, or there's a technical issue

Fix:

Issue: I want to delete or edit a schedule

Root cause: You need to modify an existing schedule

Fix:

Issue: My schedules overlap (e.g., 11 AM - 2 PM and 1 PM - 4 PM)

Root cause: Overlapping schedules can cause confusion in the send distribution

Fix:

Avoid lunch hours: Create schedules that skip 12 PM - 2 PM for B2B campaigns. People are less likely to check email during lunch.

Test morning vs. afternoon: Run A/B tests comparing morning-only sends (9 AM - 12 PM) vs. afternoon-only sends (2 PM - 5 PM) to see which performs better for your audience.

Consider timezone clusters: If you have leads across US timezones, create separate campaigns for Pacific, Mountain, Central, and Eastern. Use the same local time schedules (e.g., 9 AM - 5 PM) adjusted for each timezone.

Align with prospect behavior: If targeting busy executives, avoid early morning (they're in meetings). Try late morning (10-11 AM) or late afternoon (4-5 PM) when they're back at their desks.

Use analytics to refine: After running your campaign for 2-3 weeks, export send time data and analyze which windows produced the best results. Adjust your schedules accordingly.

Spread high-volume sends: If sending 1,000+ emails/day, use 3-4 schedules to distribute evenly and avoid spam filters or rate limits.

Weekend schedules for B2C: If targeting consumers (not businesses), add weekend schedules. Saturdays and Sundays can perform well for B2C outreach.

Name schedules clearly: Use descriptive names ("Morning prime time 9-11 AM") so team members understand the strategy at a glance.
