Proactive cost & quality control

Reduce campaign costs before you send

The real cost of bulk messaging isn't just the price of an SMS. It's paying for messages that never reach their destination.

Apifonica helps reduce unnecessary campaign costs by validating your data before messages are sent. Depending on contact quality, businesses can reduce overall campaign costs by 15% to 45%.

Improve contact quality before sending

Before launching a campaign, you can review and prepare your recipient list to improve delivery rates and reduce unnecessary messaging costs.

For businesses that require automated phone number validation within their own applications or workflows, Apifonica also offers a dedicated HLR Lookup API that can be integrated separately.

Preparing contact lists before sending helps improve delivery rates while reducing wasted spend on undeliverable messages.

Voice SMS

For critical notifications and authentication messages, Apifonica can automatically convert SMS into text-to-speech voice calls when required.

This fallback helps important messages reach recipients.
