What Is A Voice Broadcast Service?

Voice broadcasting allows companies to directly record messages and send them to customers, creating a streamlined process. It provides businesses and consumers alike with an effective and efficient way to connect.

Voice message broadcasting can be used in so many ways to communicate your message to customers and staff effectively. Here are a few ideas you could implement into your business to increase sales, improve customer engagement, and lead generation.

Marketing & Promotions

Broadcast voice messages with discounts & offers that advertise your services.

Send mass phone calls to learn what customers think or resolve their issues.

Call-To-Win Competitions

Call and broadcast opportunities to win prizes to entice your customer base.

Emergency Notifications

With voice message broadcast, you can send time-sensitive alerts to customers.

Benefits of Voice Broadcasting

There are numerous benefits to mobile and telephone broadcasting.

Variety of Use Cases

You can use voice broadcasting services for appointment reminders, payment reminders, delivery status notifications, marketing and promotions, customer loyalty rewards, emergency and weather alerts, event alerts, password resets, political campaigns, and more.

Powerful Features

Though businesses can use voice broadcasting to call customers directly, multiple features are available that integrate with programmable voice APIs to meet each company’s unique marketing needs.

Customer Engagement

The nature of voice broadcasting and the structure of its communication method create built-in opportunities for customer connection, even more so than sending a text message.

Multichannel Communication

Another voice broadcast advantage is integrating it with other mediums and applications to create comprehensive communication and marketing strategy. These include phone verification to scrub your calling list and an SMS API or SMS software to send text messages.

Saves Time and Money

Voice broadcasting already saves businesses time and money because it doesn’t require individuals to call customers one by one manually. It exponentially expedites the process by allowing you to upload contact lists, record a message, and send out mass calls to everyone.

A mass phone call campaign is more than just sending voice messages to customers. There is a strategy.

1. Set Goals

Before starting your campaign, ask yourself what goals you want to accomplish with your voice marketing platform. Do you want to generate more leads, boost brand awareness, or receive feedback on a new product?

2. Target Audience

Use demographic data to target your audience and tailor your message. Audiences radically differ depending on their circumstances in life, and the usefulness of the product or service you offer will fluctuate due to this.

3. Provide Benefits

Instead of just stating that your company is rolling out a new service, including a promotion where customers who call in or text a unique keyword will receive 60% off the service or a free trial. Simple state the benefits.

4. Call to Action

Customers won’t respond to your voicemails if they don’t know-how. Make your call to action clear and easy to follow. This way, when your audience listens to your voice messages they can respond accordingly.

5. Features

Voice marketing services have continually expanded and improved upon the features they offer. Use this to your advantage to save time and money while also adding value to your voice messages.
