Not a competition
People ask us whether they should use SMS or WhatsApp. The honest answer: it depends on the message. They are good at different things, and the best businesses use both.
Where SMS is strongest
- It reaches every phone. No app, no data, no smartphone needed. That matters when your audience includes people with basic phones or limited data.
- It's immediate and noticed. Messages arrive on the lock screen and are usually read quickly.
- It suits short, important messages. OTP codes, payment reminders, delivery updates, appointment alerts.
- You don't need the customer to have saved your number. With a sender ID, the message arrives with your name on it.
Where WhatsApp is strongest
- Richer content. Images, documents, catalogues and longer explanations.
- Conversation. Customers can reply easily and you can have a real back-and-forth.
- Customers who already live in the app. Many people check WhatsApp more often than they check anything else.
A simple way to decide
| If the message is… | Use… |
|---|---|
| A code, alert or reminder that must reach everyone | SMS |
| A short announcement to a large, mixed audience | SMS |
| A product catalogue, a receipt or a document | |
| A conversation, support or follow-up |
Using both together
A school can send fee reminders by SMS so every parent gets them, then answer questions on WhatsApp. A shop can announce a promotion by SMS and share the catalogue on WhatsApp. One channel makes sure people hear about you. The other lets them talk to you.
Both from one place
Yoola SMS supports bulk SMS and WhatsApp Business messaging from the same account, so you don't need two providers and two sets of contacts. Start with SMS to reach everyone, and add WhatsApp where a conversation helps.
