Before starting, make sure you have:

• A Dewx account (replaces your marketing agency if you do not have one)
• 30-60 minutes of uninterrupted time
• Access to any existing data you want to import
• A clear goal for what you want to achieve

Step-by-Step Instructions

Step 1: Access the Right Section

Log into Dewx and navigate to the relevant hub. For whatsapp setup, work primarily in Portal inbox. Click the sidebar icon to expand the module.

Time estimate: 2 minutes

Step 2: Initial Configuration

1. Open the settings panel (gear icon)
2. Set your preferences — labels, default values, notification settings
3. Save your configuration

Step-by-step implementation reduces time-to-value by 60% for new software tools. Customizing labels to match your terminology improves team adoption.

Time estimate: 5-10 minutes

Step 3: Import Your Data

1. Click "Import" in the toolbar
2. Choose your import method: CSV upload, direct integration, or manual entry
3. Map your data fields to Dewx fields
4. Review the preview and confirm

Operations Hub can also handle data migration — describe what you want to import and from where.

Time estimate: 10-15 minutes

Step 4: Build Your First Workflow

1. Navigate to the automation section
2. Choose a pre-built template or create custom
3. Set trigger conditions
4. Configure actions
5. Set notification preferences

New users who complete onboarding tutorials retain at 80% versus 40% for self-guided (Appcues). Start simple and add complexity later.

Common workflow examples:

• When a new contact is added, send a welcome email within 5 minutes
• When a deal moves to "Proposal Sent," schedule a follow-up for 3 days later
• When a support ticket is created, assign to the team member with fewest open tickets

Time estimate: 10-15 minutes

Step 5: Test Your Setup

1. Create a test record
2. Trigger your workflow manually
3. Verify each step executed correctly
4. Check notifications
5. Review automated messages for accuracy

Time estimate: 5-10 minutes

Step 6: Go Live and Monitor

1. Remove test data
2. Announce the new workflow to your team
3. Monitor the first 24-48 hours
4. Check the activity log in CX Hub

Users who complete a guided setup are 4x more likely to become paying customers.

Testing Checklist

• Data imported correctly (spot-check 5-10 records)
• Workflow triggers fire on correct conditions
• Automated messages have correct content
• Notifications reach the right team members
• Dashboard metrics updating in real time

Troubleshooting Common Issues

Issue: Data import shows mismatched fields. Solution: Re-run the import wizard and manually map unrecognized fields. Common mismatches: date formats (MM/DD vs DD/MM) and phone number formats.

Issue: Workflow does not trigger automatically. Solution: Check trigger conditions match your test data exactly. Conditions are case-sensitive. Verify timezone settings.

Issue: Notifications not being received. Solution: Check notification preferences in workspace settings. Verify email delivery and check spam folders.

Issue: Automated messages contain placeholder text. Solution: Edit the message template and replace {{variable}} placeholders with correct field mappings. OPS Hub can help configure templates.

Tutorial completion rates increase 3x when estimated time is displayed upfront.

Scaling This Setup for Larger Teams

If your team grows beyond 5 people, you will need to add a few additional configurations to maintain efficiency:

Role-based access. Set up user roles so team members see only the data relevant to their function. Sales sees deals and contacts. Support sees tickets and conversations. Finance sees invoices and payments. This reduces noise and prevents accidental changes to data outside someone's responsibility.

Team-based routing. As you add team members, update your automation rules to distribute work evenly. Round-robin assignment ensures no one person is overloaded while others are idle. Skill-based routing sends specialized inquiries to the team members best equipped to handle them.

Manager dashboards. Create overview dashboards that give team leads visibility into performance without requiring them to check individual records. Portal inbox provides pre-built manager views that show team metrics, bottlenecks, and trending KPIs at a glance.

Approval workflows. For teams handling high-value deals or sensitive communications, add approval steps to your automations. Proposals over $10,000 require manager review. Client communications about contract changes get flagged for legal review. These guardrails prevent costly mistakes as more people touch the system.
