How to Grow Your Business With Voice Blast

There are many ways to connect with customers, including calls, emails, and text messages. For businesses that prefer voice calling and voicemail drops, voice blasts and IVR blasts are ideal. This software is flexible, powerful, and easy to use, perfect for new and experienced businesses. Keep reading to learn more about voice-blasting APIs, IVR features, and how both can help you grow your business.

How Can Voice Blasting Improve My Business?

Voice blasts involve sending mass calls to customers using software or API, allowing businesses to connect with thousands of customers each second. This involves sending out a pre-recorded message versus having an employee make each call in real-time.

If customers respond to the message and call back, businesses can use an Interactive Voice Response (IVR) system to route calls to the customer’s needs quickly. Each routing path is dictated by a customer pressing a corresponding number or stating a specific word or phrase. Because these systems are closely linked, voice blasting may also be called IVR or call blasting.

However, remember that IVR is one of many optional features that can make voice blasting more effective. With voice blast software or API, the IVR blaster has more functionality.

Getting started with voicemail blasting is simple enough that any company can integrate it into its marketing and communication campaigns, even without extensive experience with software or APIs.

Most software or APIs are easy enough to set up that your businesses can begin sending out campaigns within the same day. Remember that every service provider has a slightly different product, so the specifics of each software or API will differ.

However, the general process remains the same. We’ve outlined the steps in this process below so that your business can become familiar with the following:

Set Your Goals

Before investing in voice blast software, your business must carefully consider what you want to get out of it. Do you want to expand your user base? Improve your response and engagement rates. Improve brand recognition?

Review Your Contact Lists

Once you decide on software, you must upload your contact lists. Before doing this, review and scrub your contact lists to remove any phone numbers that are inactive or incorrect.

Upload and Segment Contacts

Upload your newly-scrubbed contact lists and segment them into targeted audiences. Consider which audiences would respond best to specific campaigns and for what reasons. Your driving focus should always be effectiveness.

Record Campaign Messages

Depending on the needs of your business and how you prefer to connect with customers, you can create one-time messages or reusable voice templates. Both have advantages, so creating a few of them may be wise.

Schedule Campaigns

Once your custom or templated voice blast is ready, you can send it out immediately or automatically schedule it to send at a future date and time. This should depend on your segmented audience and what works best for them.

Use Available Resources

If your business has questions or concerns during this process, do not hesitate to contact your provider and use available resources. These should include documentation, tutorials, and customer service.

Each of these steps has opportunities to further the goals of either your business or the goals of a specific marketing and communication campaign. Ideally, these goals should align and support each other.

After you set up your voice broadcast API or software and start sending out campaigns, there is another step your business should take: analyzing each campaign’s performance. To gauge how well your campaigns support your goals in Step 1, utilize features like real-time reporting to see listen/ open rates, response and engagement rates, and similar information.

Based on these reports and any feedback you gain directly from customers, you can tweak future campaigns to make them more closely support your goals and perform more effectively. This might include adjusting the campaign message, targeted audiences, send times and dates, or a combination of these factors.

Voice broadcasting is an effective medium, but only if businesses use it to its fullest extent. This means taking advantage of available features to optimize resources and savings and carefully adjusting your campaigns to make them as effective as possible.

To make it even more effective, here are some tips for your voice broadcasting campaigns:

  • Use Multi-Lingual Capabilities Many voice blast and IVR blast software offer translation and multi-lingual capabilities so that you can connect with customers regardless of what language anyone speaks.
  • Leverage Full Voice Blast Uses Voice blasting and IVR software can be used for various purposes, including marketing, customer surveys, appointment reminders, lead routing, fraud alerts, and more; businesses should take advantage of this flexibility.
  • Integrate Multiple Software/ APIs For services that offer multiple software and API options. Your business can integrate them for more effective communication across all channels; common APIs include SMS, verification, and email services.
  • Ensure Compliance Use features like call quality monitoring, call recording, and call and control to ensure your business complies with all federal regulations and industry best practices, avoiding fines or other penalties.

For more tips on making your voice broadcasting as effective as possible, consult your chosen and potential service providers for recommendations.

Choosing the Best Voicemail Blast Service

Many voice blast services are available, some only specialize in voice blasting, and some offer various communication and marketing services. The latter can allow your company to integrate multiple services and utilize the collective benefits. However, both types can still be serious contenders.

Below are some tips on how to choose the best blast service providers:

  1. Research, Research, Research Choosing the best voicemail blast service starts and ends with research; look at the available voice blast services and compare their pricing, software or APIs, customer service, etc.; compare the pros and cons for each.
  2. Analyze Features Features can make or break your business’s communication and marketing experience; carefully review available features and see how they could benefit your business, currently or in the future.
  3. View Demos To understand how the software or API will work in real-time, ask each service provider to view a demo of it in action; it would also benefit your business if you could take advantage of a free trial or free trial credits.
  4. Read Reviews Many service providers make claims as to their software or API’s capabilities, but customer reviews reveal how well the software or API works and whether these claims are substantiated (and to what extent)

The best service providers will have a record of excellence, as indicated by positive customer reviews and how the software or API performs during demos and free trials. There should be ample evidence that customers are pleased with the software or API regarding functionality, scalability, and support.
