How to Connect Mailchimp to WhatsApp with DMHub

Mailchimp is great for email marketing. But email engagement has been declining for years. Average open rates across industries are now 21%, down from 28% five years ago. For businesses in WhatsApp-dominant markets, those numbers are even lower because email simply isn't the primary channel.

DMHub connects Mailchimp to WhatsApp, letting you extend your email campaigns to the channel where your audience is most active. Same audience, same segments, dramatically higher engagement.

What This Integration Does

• Audience sync: Mailchimp lists sync to DMHub contacts bidirectionally
• Campaign extension: Send WhatsApp versions of your Mailchimp campaigns to contacts who prefer WhatsApp
• Cross-channel analytics: See email and WhatsApp engagement side by side
• Segment sharing: Mailchimp segments available for WhatsApp targeting in DMHub
• Opt-in management: Mailchimp subscription status syncs with DMHub WhatsApp preferences

Step-by-Step Setup

Step 1: Connect Mailchimp

1. In DMHub, go to Settings > Integrations > Mailchimp
2. Click Connect and authorize with your Mailchimp account
3. Select which audience lists to sync
4. Map Mailchimp fields to DMHub contact properties

Step 2: Sync Your Audience

DMHub imports your Mailchimp subscribers and matches them to WhatsApp contacts via phone number. For subscribers without phone numbers, you can:

• Add a "WhatsApp number" field to your Mailchimp signup forms
• Run a campaign asking email subscribers to opt in to WhatsApp updates
• Use DMHub's web widget to capture WhatsApp numbers from website visitors

Step 3: Create Cross-Channel Campaigns

For each Mailchimp campaign, create a WhatsApp companion:

1. Design your email in Mailchimp as usual
2. In DMHub, create a WhatsApp message with the same offer or content
3. Target: Mailchimp contacts who have a WhatsApp number and haven't opened the email
4. Timing: Send the WhatsApp message 24 hours after the email to catch non-openers

Step 4: Measure and Optimize

Compare engagement across channels:

• Which contacts engage more on email vs WhatsApp?
• What content performs better on each channel?
• What's the incremental lift from adding WhatsApp to your email campaigns?

Global Impact

A fashion brand with 50,000 Mailchimp subscribers added WhatsApp as a second channel:

• Email-only campaign: 19% open rate, 3.1% click rate
• Email + WhatsApp: 19% email open + 94% WhatsApp read = 67% total reach
• Revenue per campaign increased 42% from the incremental WhatsApp engagement
