Call Blasting for Business
Does your business want to connect with users on a more personable level? Is there information you need to communicate which would be inappropriate for a text or email? Are you seeking to create more robust communication and marketing strategies? If these are true, your businesses would greatly benefit from a call-blasting service.
Call blasting allows businesses to send bulk calls to customers worldwide, instantly connecting to thousands of users. Call blasting software and service expedite this process by using an interface to create, schedule, and even send these calls. Read on to learn about call blasting, how your business can leverage it, the benefits you will experience, what pricing you can expect, and more.
Call Blasting Services for Businesses
If your business needs clarification about the meaning of call blast, do not worry: call blasting, also known as phone blasting and voice broadcasting, refers to a communication method wherein hundreds (or thousands) of calls are sent out to customers simultaneously.
To accomplish this, businesses use a call blasting or broadcasting service, streamlining and automating this process so that businesses no longer have to do it manually.

All About Call Blasting
Call blasting is an often-overlooked component of marketing and communication strategies. Though perhaps not as expedient as bulk SMS messaging, phone blasts offer a more personalized experience that users appreciate. This can help businesses build stronger customer relationships, which can be especially important for the educational, political, financial, and medical sectors.
What is Phone Blasting?
Call blast online allows businesses to instantly send more than 10,000 calls per minute to users worldwide, all mediated through a website interface or software. Both have benefits: websites require no programming, but the software provides more customizable capabilities (i.e., it is scalable and can grow with your business). Though it may seem too good to be true, call blasting is legal, provided businesses follow federal regulations. Such regulations include gaining prior consent to contact users, refraining from sending illegal or inappropriate content, and allowing users to stop receiving calls at any time.
Phone blasting is more economical than manually calling users, which could take one employee all day (depending on how many calls need to be placed) or tie up multiple employees for an hour or more. Though your business is unlikely to find a free phone blast service, the current software providers offer cost-effective options with flexible plans and ample opportunities for discounts.

How Do You Call Blast?
Call blast websites offer an interface that handles every component of the voice broadcasting process with minimal input from businesses. You upload your contact lists, record or type your desired message, and schedule a time for the call blasts to send.
Here is a breakdown of each step in more detail:
- Contact Lists – Upload your user contact lists, ideally segmented into the primary groups that your business targets for communication. (For example, a school may upload separate lists for students, teachers, parents, administrators, etc.)
- Call Message – Your business can either record a message or upload a written script and use speech software to turn it into a verbal message. The latter option is advantageous if you need to translate your message or want to leverage a specific accent.
- Blast Schedule – After completing these steps, select the users you want the blast to go to and schedule a date and time for it to send. You can send the call blast immediately after crafting your message or schedule it for the future.
With call-blasting software, your business can reach an extraordinary number of users in seconds. Such software is handy whether you are a small business looking to better connect with your community or a large corporation wanting to expand your customer reach into new markets.
But remember: to remain compliant with federal and state regulations, your business must have prior permission from users to contact them. Otherwise, your calls will be labeled as spam, and your business may be subject to service suspensions, fines, and other penalties.

Call Blast Rules for Business
Call blast is a great way to reach a large audience with your message. However, there are a few fundamental rules that businesses need to follow to ensure that their call blast are effective:
The average person's attention span is limited, so it's essential to keep your call blast concise and to the point.
No one wants to listen to a fuzzy or crackling message, so make sure that the audio quality of your call blast is top-notch.
Your call blast message should be delivered professionally and straightforwardly. Avoid using slang or jargon that could confuse your listeners.
Make sure your call blast message includes a call to action, such as telling your listeners to visit your website or giving them a phone number to call. By including a call to action, you'll better gauge the effectiveness of your call blast message.

Call Blasting Services Explained
If you want to learn more about phone blasting, we put together a quick YouTube video explaining how these services work, using our service as an example. (Seriously, it’s super quick— less than one minute.) This video covers what these services do, how they work, and some benefits.
For those who want a transcribed rundown, these services offer an all-in-one voice-calling solution by allowing you to send out thousands of calls in minutes. We offer two options for the call: uploading a prerecorded sound file or a script that our text-to-speech software reads with your choice of language and accent.
We also touch on one of the most popular features of call blasting services: interactive voice response (IVR) menus. With IVR, your business can automatically and quickly route incoming calls to the correct department (or personnel) instead of manually routing them. Some companies associate each routing option with a number (i.e., ‘press one for …’), while others choose spoken words or phrases to associate with each routing option (i.e., ‘say one for…’).
Other popular features include answering machine detection (AMD) and text-to-speech (TTS) capabilities. The former indicates whether an actual human, fax machine, or answering machine responds to your calls; the latter translates written text into verbal speech, also acting as a translator if needed.
