But in 2025, if the goal is do marketing<\/strong>, automate conversations<\/strong> And improve customer experience<\/strong>, the real question is not \u201ccan I send SMS from a VoIP number?\u201d, but rather: What is the most effective and comprehensive channel for business conversations?<\/strong><\/p>\n In Italy, the answer for many companies is WhatsApp Business<\/strong>: a channel already present on almost everyone's phone, with richer conversations than SMS, the possibility of approved templates, automations, catalogues and above all integration with Conversational AI<\/strong>.<\/p>\n In this guide we will see:<\/p>\n \u201cVoIP texting\u201d refers to sending and receiving messages using a VoIP number<\/strong> (therefore, a number managed via the Internet and not tied to a physical SIM card). In practice, the company maintains its own telephone identity (the number customers call) and, if that number is enabled, can also receive\/send messages.<\/p>\n Technically, the text travels as data over the Internet to the messaging provider, and only at the final stage is it delivered to the recipient as an SMS (if the recipient is on a traditional mobile network). This makes VoIP messaging convenient for those who work from a PC, use CRM systems, help desks, or want to integrate automations.<\/p>\n For the end user, often nothing changes: they receive a text message. For the company, a lot changes:<\/p>\n The problem is that SMS remains a "poor" channel\u201c<\/strong>No interactive buttons, limited contextualization, difficulty managing long conversations, and often costs that increase with volume. For many companies, the natural progression is to move conversations to WhatsApp Business, keeping SMS as a backup channel.<\/p>\n If you're considering VoIP messaging for marketing or customer service, it's helpful to compare what you get with SMS versus WhatsApp Business.<\/p>\n WhatsApp allows:<\/p>\n For an Italian brand, this means being able to do customer experience<\/strong>, not just \u201cnotifications\u201d.<\/p>\n With WhatsApp Business and a platform like SendApp, you can build automated workflows: cart recovery, post-purchase follow-up, appointment reminders, onboarding, NPS, and customer reactivation. SMS can do this to a more limited extent; WhatsApp makes it more effective because the conversation is continuous and contextual.<\/p>\n The leap in quality comes when you combine WhatsApp with a AI chatbot<\/strong> Able to understand requests, respond coherently, and hand over to an operator when needed. With conversational AI, you can:<\/p>\n Learn more about the AI part here: AI Chatbot for WhatsApp<\/a>.<\/p>\n Below you'll find concrete examples designed for Italian companies. In many scenarios, SMS from VoIP can be a useful channel, but WhatsApp Business (with official APIs) is becoming the primary channel for conversions and engagement.<\/p>\n Scenario:<\/strong> An online clothing boutique in Milan that wants to promote its spring collection and increase repeat purchases.<\/p>\n SMS\/VoIP approach:<\/strong> Sending a text with a link to the landing page works, but it's not very distinctive and doesn't handle questions well ("What size do you recommend?", "Do you have cream?").<\/p>\n WhatsApp approach with SendApp:<\/strong><\/p>\n Typical result: more useful conversations<\/strong> and less \u201ccold\u201d traffic to the site.<\/p>\n Scenario:<\/strong> Beauty salon in Bologna with a full schedule and many last-minute cancellations.<\/p>\n WhatsApp approach:<\/strong> Automatic reminder 48 hours in advance + message 4 hours in advance with "Confirm" \/ "Move" buttons. If the user chooses "Move," the AI suggests 3 alternative slots and updates the reservation (or passes it on to the operator).<\/p>\n In this case, SMS remains useful as a backup for those who don't use WhatsApp, but the primary management on WhatsApp reduces no-shows and lightens the voicemail.<\/p>\n Scenario:<\/strong> Boiler maintenance company in Turin that receives repetitive requests (costs, availability, documents, warranty).<\/p>\n Recommended automation:<\/strong><\/p>\n This type of flow is much more natural on WhatsApp than a chain of SMS.<\/p>\n Scenario:<\/strong> Real estate agency in Rome that receives contacts from portals and social media campaigns.<\/p>\n WhatsApp Flow with AI:<\/strong> Within 60 seconds of the lead, a welcome message and 3 questions (region, budget, timing) are asked. The AI classifies the lead (hot\/warm\/cold) and suggests an appointment. The agent only engages with qualified leads.<\/p>\n Here, the speed and quality of the conversation make the difference: an SMS can initiate contact, but WhatsApp turns it into a negotiation.<\/p>\n When a company starts with a VoIP PBX or a "historic" business number, the frequent question is: "Can I use the same number for WhatsApp?" It depends on the technical constraints and the current setup, but the strategic objective is clear: consolidate the brand identity<\/strong> and offer a reliable conversational channel.<\/p>\n To do marketing automation and support at scale you need the Official APIs<\/strong>Template management, delivery quality, scalability, multi-operator, integrations. With SendApp, you can start from here: Official WhatsApp APIs<\/a>.<\/p>\n A common mistake is using WhatsApp only for bulk emails. It works best if you include it in your email lifecycle:<\/p>\n Each stage can be automated with rules, tags, segments, and dynamic messages.<\/p>\n Whether you send SMS from a VoIP number or WhatsApp messages, compliance isn't a detail: it's part of performance. Clean lists and clear consent improve deliverability, reputation, and results.<\/p>\n Sending everyone the same message is the fastest way to increase blocking and unsubscriptions. It's best to segment by:<\/p>\n With WhatsApp, users expect dialogue, not spam. Therefore, conversational AI must:<\/p>\n In many companies the best combination is:<\/p>\n This way you reduce conversational costs, increase marketing effectiveness and maintain broad coverage.<\/p>\n Scenario:<\/strong> Restaurant in Naples with reservations, takeout, and delivery.<\/p>\n Objective:<\/strong> Increase weekday bookings and reduce callbacks.<\/p>\n Flow with SendApp:<\/strong><\/p>\n This is real marketing automation: not just sending, but managing the end-to-end experience.<\/p>\n SendApp offers complete solutions to manage WhatsApp Business professionally and efficiently:<\/p>\n Learn what VoIP texting is and why WhatsApp Business with SendApp is ideal for marketing automation and conversational AI.
