# Can I modify a campaign that’s already running?

Yes! You can edit any recurring campaign at any time.

**What Can Be Edited:**

✅ Campaign name and description
✅ Message content
✅ Frequency (interval and unit)
✅ Recipients (batch numbers or groups)
✅ Sender ID
✅ DLT Template ID
✅ Message type (Text/Unicode)
✅ Start date, end date, time
✅ All optional settings (Flash, Link tracking, etc.)

**What Cannot Be Edited:**

❌ Historical execution reports
❌ Already sent messages
❌ Past trigger dates

**How to Edit:**

1. Go to **Compose SMS → Recurring SMS**
2. Find your campaign
3. Click the **"Edit"** button (pencil icon)
4. Modify any fields needed
5. Click **"Update Recurring SMS"**
6. Changes apply to all future executions

**Important Notes:**

⚠️ **Changes apply immediately:**

- Next execution uses new settings
- Already scheduled executions use new settings
- Past executions remain unchanged in reports

⚠️ **Frequency changes recalculate trigger:**

- If you change from "Weekly" to "Monthly"
- System recalculates next trigger date
- Based on last execution + new frequency

⚠️ **Recipient changes:**

- Adding groups: New contacts receive messages
- Removing groups: Those contacts excluded
- Changes effective from next execution

**Best Practices:**

1. **Test Before Changing Recipients:**

1.

- If unsure, create a duplicate campaign
- Test with small group first
- Then update main campaign

**2. Update Message Carefully:**

1.

- Review character count
- Check personalization placeholders
- Verify DLT compliance

**3. Consider Creating New Campaign:**

1.

- If changes are major
- Keeps historical reports separate
- Easier to compare performance

**4. Document Changes:**

1.

- Update campaign description
- Note why changes were made
- Helps future reference

**Example Scenarios:**

**Scenario 1: Seasonal Message Update**

- Original: "Winter sale ends soon!"
- Updated: "Summer collection now available!"
- Edit message content only

**Scenario 2: Frequency Adjustment**

- Original: Every 1 Week
- Business grows, want more frequency
- Updated: Every 3 Days

**Scenario 3: Expanding Audience**

- Original: Group A only
- Add Group B and Group C
- Check recipient count doesn't exceed budget
