Why direct messages win in 2026

Average email open rate: 23%. SMS open rate: 95% within the first 3 minutes. WhatsApp open rate: 85-90%. When you have something important to communicate (an order confirmation, a limited offer, an appointment reminder), no channel beats the phone's direct inbox.

SMS marketing: what works and what doesn't

When SMS makes sense

Order or delivery confirmations (zero conversion, but better customer experience)
Appointment reminders (cut no-shows by 40-60%)
Flash sales with real urgency (max 24h)
Exclusive discount codes for SMS subscribers
Back-in-stock alerts for sold-out products

Costly mistakes in SMS marketing

Sending without explicit GDPR consent (ANPC fine of up to 20M EUR)
Long messages that get cut off or cost double
Excessive frequency: 2-4 SMS/month is the most your audience will tolerate
No clear way to unsubscribe (STOP to number X)

SMS platforms in Romania

SMS Eutelia, SMSLink.ro, Twilio (international), Brevo (has an SMS module). Cost per SMS in Romania: 0.04-0.09 EUR, depending on volume and provider.

Frequently asked questions

Can I send promotional SMS messages to my existing customers without asking for consent again?

If you have their number from an existing commercial relationship, told them you would use it for marketing communications and they did not object, you may send SMS messages about similar products or services (soft opt-in). For new customers, explicit opt-in is mandatory.

How much does the WhatsApp Business API cost for a small business?

A provider such as WATI or 360dialog charges 30-80 EUR a month for the platform plus 0.04-0.09 EUR per conversation (not per message). For a small volume (100-500 conversations a month), the total cost is 50-150 EUR a month. The WhatsApp Business app covers small needs without the API.

Does WhatsApp work for B2B?

Yes, surprisingly well in Romania: the local market prefers WhatsApp even for business. A post-meeting follow-up on WhatsApp gets a response rate of 60-80%, compared with 20-30% for email. A word of caution: professionals prefer to keep their personal and work inboxes separate, so respect those boundaries.

Can I automate replies on WhatsApp?

Yes, through the WhatsApp Business API with a chatbot integration (Manychat, Tidio or a custom chatbot). You can automate FAQ replies, lead qualification, order confirmation, delivery tracking and appointment reminders. The chatbot must state clearly that it is automated and offer a hand-over to a person.

What is the cost difference between SMS marketing and WhatsApp marketing?

SMS: a fixed cost per message (0.04-0.09 EUR), with no platform required. WhatsApp API: a cost per conversation (not per message) plus a monthly platform fee; more expensive per message, but richer conversations (images, documents, buttons). For short notification messages, SMS wins on cost. For interactive communication, WhatsApp.
