FAQ – Frequently Asked Questions

Is it possible to integrate SMS sending with my CRM or current system?

Yes. Zenvia offers one of the most robust and well-documented APIs on the market. You can automate messages based on triggers from your system (e.g., purchase confirmation, invoice due date) or integrate natively with partner platforms through Zenvia Customer Cloud.

Does SMS work for customers who do not have internet access?

Yes. SMS uses the GSM mobile network, ensuring your message reaches any mobile phone, from the most modern smartphones to basic devices, without relying on 4G, Wi-Fi, or app installations.

What is the difference between sending via an Official Broker (Zenvia) and “SIM farms”?

Security and delivery assurance. Zenvia uses official routes directly connected to mobile operators. This prevents your number from being blocked as spam (common with SIM farms/gray routes) and delivers over 98% delivery rates, in addition to providing legal validity for notifications and billing messages.

Can I send links and images in my SMS campaigns?

The SMS protocol is text-only (up to 160 characters), but you can enhance the experience by using a link shortener, like the one available in Zenvia Customer Cloud. With it, you send a short link that leads to an image, video, or landing page, and our platform tracks clicks, generating accurate conversion reports.

What is a Short Code and when should I use it?

Short Codes are short numbers (e.g., 28555) designed for high volumes and high credibility. They inspire more trust among end users than regular mobile numbers (Long Numbers) and have traffic priority with carriers. They are ideal for banks, large retailers, and security validation (2FA).

How do I know if my customer actually received the message?

Unlike homemade solutions, Zenvia’s platform provides real-time delivery status reports. You will know exactly who received the message, who clicked the link, and which numbers are invalid, helping you clean your database and reduce costs.
