01 Lead story

Accounts getting restricted? Put the business on the official WhatsApp API.

When a company number is carrying real customer volume, it belongs on the WhatsApp Business Platform — the official Cloud API. Best SMS Bulk connects that API to OneBox, so the same number your customers already know is answered by the whole team, from one inbox.

Official WhatsApp API workspace with a protected business phone

The official API keeps business messaging on the platform Meta built for companies.

Best SMS Bulk is a Meta Business Partner. The platform gives you the Cloud API, approved message templates, and OneBox as the place the team works. Alerts, reminders, and campaigns leave through templates. Replies land in a shared inbox, with assignment, labels, and a record of the conversation. Chatbots and your own systems can sit on the same connection.

What the API gives a business
Official Cloud API onboarding · multi-agent OneBox inbox · approved templates for notifications and campaigns · quality and opt-in controls · web and Android for the team

WhatsApp still expects opted-in contacts and a healthy quality rating. The API is the setup that matches those rules. A personal app, or an unofficial tool, is what usually puts a business number at risk.

02 Now in OneBox

Monthly and yearly subscriptions, with a reminder before each renewal.

Gyms, clinics, retainers, memberships, service plans — if customers pay on a cycle, Renewals now lives inside OneBox. Add the customer, the plan, the amount, and a monthly or yearly cycle. OneBox sends a welcome on WhatsApp, then a reminder a few days before the next date.

Renewal calendar and a WhatsApp reminder on a customer phone

A calendar of renewals, and a message that reaches the customer before the date.

Set it once. Name, phone, plan, value, start date, and how often it renews. Choose how many days ahead the reminder goes out.

Bring the list in. Add people one by one, or import them from Excel. Stop a subscription and further messages stop with it.

03 Now in OneBox

Tasks List — the follow-up stays next to the chat.

Notes and checklists are part of OneBox. Open Tasks List from the inbox, write the work down, and tick it off. A task stays private until you share it. Hand one note to a colleague, or share a whole list, when a follow-up needs more than one person.

Tasks List with checklists beside the OneBox conversation

Checklists on one side, the customer conversation on the other.

From any customer message, choose Add to Tasks List. The note is titled with the customer\'s name and number, so the promise you made in chat is still there after the thread moves on. Pin it, color it, or file it under a category.

04 Now in OneBox

Bulk SMS and bulk WhatsApp, sent from the same inbox.

Campaigns have moved into OneBox. Send WhatsApp and Send SMS each follow the same four steps: choose when to send, write the message, add the recipients, then review and send. Schedule it, or send it now, without leaving the place the team already answers customers.

WhatsApp and SMS campaigns prepared for many recipients

One desk for both channels: WhatsApp on the left, SMS on the right.
