Can we use one business WhatsApp number for marketing and sales instead of giving customers different numbers to contact?

One number connects campaigns with sales conversations

With WhatsApp Business API connected to respond.io, your business can use the same number for general inquiries, click-to-WhatsApp ads, broadcasts and individual sales conversations. Marketing can send a promotion, and your sales team can continue the conversation when a customer replies.

WhatsApp broadcasts let your team send or schedule campaigns to selected customer segments. Replies arrive in the inbox where your team already handles incoming inquiries. A customer who responds to an offer can ask questions and discuss a purchase in that same WhatsApp chat, without being asked to message a different sales number.

Customers keep one chat while your team hands it over

Multiple salespeople can work from one business number through respond.io's team inbox. Each conversation can be assigned to an owner, and the next salesperson can review its history before replying. The customer continues speaking to your business through the same number, even when a different team member takes over.

For campaign replies and ad inquiries, AI Agents can answer questions, qualify interest, recommend products and book appointments. When a salesperson is needed, the AI Agent assigns the conversation to them with its history intact. Workflows, respond.io's rule-based automation, can also route conversations according to criteria such as branch or language.

For example, a customer can reply to a promotion asking about availability. An AI Agent can clarify what they want and pass the conversation to a salesperson, who continues from the same number with the earlier messages visible. The customer does not have to repeat the request in another chat.

WhatsApp messaging rules still apply to one shared number

Using one number does not remove WhatsApp's requirements for outbound messages. Marketing broadcasts require customer opt-in and approved message templates. For ordinary sales conversations, your team can send free-form replies within 24 hours of the customer's last message. After that window closes, follow-up requires an approved template.

Businesses with fewer than 500 conversations a month can usually run a single contact number on the WhatsApp Business App. Above that volume, sharing one number across campaigns and sales follow-ups needs the WhatsApp API and a shared inbox like respond.io's.
