Email has been the default for years, but the channel your customers actually open first looks a lot different these days. Consider that Meta reports that WhatsApp has more than 3 billion active users worldwide1. And yet, most businesses are either sitting on the sidelines entirely or they’ve set up WhatsApp as a separate silo with no connection to the campaigns, contacts, or automations they’ve already built in their email marketing platform.
That gap is an opportunity. The advantages of WhatsApp as a channel are compelling on their own. But when WhatsApp is natively integrated in Mailchimp alongside your audience data, email workflows, and reporting in Mailchimp, the picture changes.
So, what are the advantages of WhatsApp in Mailchimp? This article covers what makes WhatsApp worth using and why the platform you use it on matters more than most businesses realize.
The advantages of WhatsApp fall into three areas that reinforce each other: reach, engagement, and platform fit. WhatsApp gives you access to a massive, already-active audience.
In a study published by Meta, 74.6% of consumers trust a business more when they can exchange messages with them directly.2 And when it runs through Mailchimp, it connects to the customer data and cross-channel workflows that turn those messages into real results.
Reach advantages with WhatsApp and Mailchimp
WhatsApp starts with an audience advantage that no other channel can replicate. Here's what that looks like in practice:
Your audience is already there
WhatsApp is the most widely used messaging app in the world, which means businesses don't need to convince anyone to download a new app, create an account, or learn a new platform.
Once you’ve obtained consent to send WhatsApp messages, the friction that comes with building an audience on a newer channel simply doesn't exist here. On WhatsApp, your customers are already active, checking it daily, and comfortable using it to communicate with people and organizations they trust.
A channel customers associate with people they trust
WhatsApp is where people have their most personal conversations. That context carries over to business messaging in a meaningful way.
A verified business profile lets your brand step into that space with your name, logo, and details displayed upfront, so customers know exactly who they're hearing from before they open a single message.
Engagement advantages when you connect Mailchimp and WhatsApp
The reach is there, but what determines results is what happens after a message lands, and how Mailchimp makes each one smarter.
Messages that actually get read
According to Meta, 80% of people globally already message with a business weekly on WhatsApp.3
For time-sensitive messages, high-priority announcements, or anything where visibility directly affects outcome, WhatsApp is in a category of its own. Getting seen is the first problem in marketing, and WhatsApp largely solves it. That immediacy is also what makes conversational commerce possible. A customer sees the message while it’s still relevant, replies, and can act on it without ever leaving the chat.
Rich content that drives action
WhatsApp messages aren't limited to text. Businesses can include images, promo codes, quick reply buttons, and tap-to-call options, giving customers a clear path to act without ever leaving the conversation.
Two-way conversations, not one-way broadcasts
Customers can reply to your WhatsApp messages, and when your WhatsApp integration runs through Mailchimp, those replies land in a single inbox alongside each customer's full history.
Your team can see what someone purchased, what they've clicked, and what they've asked before, all in one view. No toggling between tools, no missing context, and no starting the conversation from scratch every time a customer reaches out.
Messages that feel personal, not promotional
WhatsApp's format is conversational by design. A message that arrives in the same place as texts from a customer's closest contacts reads differently than a promotional email in a crowded inbox.
When the message is also relevant and personalized to what someone has actually bought or browsed, it stops feeling like marketing and starts feeling like useful information from a business that's paying attention.
Platform advantages (why Mailchimp changes the equation)
Standalone WhatsApp tools work within WhatsApp. Mailchimp works across your entire marketing setup, and that changes what WhatsApp can actually do.
Segmentation powered by everything you already know
Mailchimp lets you target WhatsApp messages using purchase history, email engagement, tags, sign-up source, and more—the same data already driving your email and mobile messaging strategy.
A standalone WhatsApp tool doesn't have any of that. It knows who opted in to WhatsApp and nothing else. Mailchimp knows your whole customer, which means your WhatsApp sends can be as precise as your best email campaigns.
Automations that work across every channel
With Mailchimp, you can build a single automation that spans email, SMS, and WhatsApp in one flow. An email goes out first. If it goes unopened, a WhatsApp message follows. If a customer clicks, the next step adjusts accordingly.
Every trigger is based on what a contact actually did—not on a timer that fires regardless of behavior. That's a level of coordination that standalone tools simply can't replicate.
One place to plan, send, and measure
WhatsApp campaigns sit in the same calendar and reporting view as your email and SMS sends. Delivery rates, click rates, and conversions are all visible in one place, with no exporting, no manual stitching, and no gaps in the picture.
When you can see how every channel performs side by side, the decisions about where to invest and what to test next become a lot clearer.
List growth without starting over
Your existing Mailchimp signup forms can collect WhatsApp consent at the same time as email opt-ins, making WhatsApp integration a seamless addition rather than a separate project. There's no separate list to build, no parallel setup to manage, and no reason to start from zero.
The audience you've already grown becomes the foundation to opt-in for your WhatsApp channel from the moment you turn it on.
WhatsApp messaging advantages by industry
The advantages of WhatsApp apply across sectors, but the use cases look different depending on the business. Here's how three of Mailchimp's core customer groups put the channel to work:
Retail
Retail brands get some of the most immediate returns from WhatsApp.
Abandoned cart messages, personalized promotions based on past purchases, order and shipping updates, and loyalty program alerts are all high-relevance use cases that perform well in a channel where open rates are near-universal. Connected to Mailchimp's segmentation, those messages reach the right customers at the right moment.
Entertainment & Leisure
Hotels, tour operators, and travel brands can use WhatsApp to stay in touch with guests from booking confirmation through well after checkout. That means sending pre-arrival information, room upgrade offers, day-of logistics, and post-stay follow-ups, all automated and personalized based on reservation data.
Entertainment venues and event companies can also use WhatsApp to reach fans directly, sharing event announcements, ticket drops, on-site logistics, exclusive content, and post-event recaps; all in the same channel fans already check throughout the day.
Publishing
WhatsApp offers direct, algorithm-free access to readers and listeners. New content alerts, exclusive drops for subscribers, and re-engagement campaigns for lapsed readers all land without fighting for inbox placement or dealing with deliverability variables.
Subscription-based publishers in particular can use the channel to make their most engaged readers feel like insiders.
Start putting WhatsApp to work in Mailchimp
The advantages of WhatsApp are real on their own. Connected to Mailchimp, every send is backed by the audience data, automation logic, and reporting you've already built, so the channel works harder from day one.
If you're already using Mailchimp for email or SMS, adding WhatsApp doesn't mean starting over. It fits into what's already there and gives you a direct line to a channel your customers check constantly. Explore WhatsApp messaging in Mailchimp.
