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.

Step 2: Open campaign schedule settings

Inside the campaign, click the gear icon, then select Schedules & launch, and click Create a new schedule. This opens the schedule editor where you can add another sending window.

Step 3: Configure the new schedule

In the schedule editor, fill in the schedule details using the fields shown in the UI:

You’ll also see an estimate of how many new leads this schedule can reach per day. When you're done, click Create new schedule.

Step 4: Confirm the schedule was added

After saving, the new schedule appears under Your campaign schedules alongside the existing default schedule. You can repeat the same process to add more time windows.

Step 5: Create a second schedule

Click Create a new schedule again under Your campaign schedules.

Step 6: Configure Schedule 2 details

Use the same fields as before to create another time window. Example configuration:

Step 7: Save and review

Save the schedule, then review the list under Your campaign schedules to make sure all time windows appear correctly.

Step 8: 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 9: 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

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.
