WhatsApp is where your customers already are, but running marketing campaigns there comes with rules. HellouOne's new marketing campaign tools give you everything you need to do it right, with consent handling built into the core of the product.
Why consent comes first on WhatsApp
WhatsApp is a personal channel. People use it to talk to family and friends, so an unwanted message from a business feels far more intrusive than an email ever does. WhatsApp's rules reflect that. Businesses need permission before sending marketing messages, marketing templates are reviewed, and every account has limits on how many people it can reach. Customers can also block or report a business, and that feedback affects the account's quality rating and how much it is allowed to send. Respecting consent is the right thing to do, and it is also what keeps your campaigns running.
How a campaign works in HellouOne
Start by uploading your audience as a CSV. Every template is validated before sending, and the send engine enforces quotas and tier limits so you stay within WhatsApp's policies. Delivery tracking shows you what was sent, delivered, and read.
A typical campaign starts with a clean list. Export your contacts from your CRM, your online store, or your booking system, and upload the CSV. Pick a marketing template, fill in the personalized fields, and review who will receive it. Because templates are validated before anything is sent, formatting mistakes and missing variables are caught early instead of landing on your customers' phones. Quotas and tier limits are applied automatically, so a large send is paced to stay within what your account is allowed to do.
After the send, delivery tracking gives you a clear view of the results. You can see how many messages were delivered and read, spot numbers that failed, and compare campaigns over time to learn which offers and timing work best for your audience.
STOP and START, handled for you
The part that matters most is consent. Customers can opt out with a STOP keyword and opt back in with START, and HellouOne tracks it all automatically. Your campaigns only reach people who want to hear from you, which protects your sender reputation and keeps you compliant.
This matters more than it might seem. Without automation, someone has to read every reply, notice the opt-outs, and remember to remove those numbers from the next list. It is easy to miss one, and a single message sent to someone who asked to stop can turn into a block or a report. With HellouOne, the opt-out is recorded the moment it arrives and respected in future campaigns automatically. If the customer changes their mind and sends START, they are back on the list without anyone on your team lifting a finger.
Putting it into practice
Consider a restaurant that wants to announce a new weekend menu, or an online store preparing a seasonal sale. Both can upload their customer list, choose a template with a clear offer, and send it to the people who agreed to hear from them. Anyone who replies STOP will not be contacted again, and the business can focus on the customers who are genuinely interested. Over time, a list built on consent tends to perform better, because the people on it actually want your messages.
A few habits help you get the most out of every campaign. Send only when you have something useful to say, keep messages short and specific, and make it clear who is writing and why. Segment your CSV by interest or past purchases so each group gets an offer that fits. Then review the delivery and read numbers after each send and adjust the next one.
From the campaign UI you can manage audiences, templates, and settings in one place. It is marketing on WhatsApp the way it should be: effective, measurable, and respectful of the customer.
