Boost Sales From Existing Customers


Boost Retail Sales & Service With Voice Broadcasting

Many retailers, whether an online eCommerce website or a brick and mortar retail store know keeping in touch with customers on a regular basis is extremely important.

Email Marketing is good, but...

Sending an email broadcast from time to time is a great way to stay in touch with customers.

There are a couple of problems though.

Problem #1) Everyone is doing it.

Customers inboxes become flooded with emails and ultimately get ignored.

Problem #2) You may not have customers email address.

There is another option.

Voice Broadcast? No way! On second thought...

Using a voice broadcast from time to time can be a game changer.

You might be thinking, I would never call my customers with an automated phone call.

Is it really that big of a deal?

Think about it.

Your customers already receive automated phone calls.

Perhaps, it is an important call from the school or a dentist appointment reminder phone call.

Or worse yet, perhaps your competitor is using an automated phone call to remind them about special VIP sales or courteous customer service satisfaction surveys.

How Does Voice Broadcasting Work?

Generally speaking, here is how it works.

When your customers receive the automated call, they will first look at the Caller ID display on their phone.

The Caller ID display will show your Company Phone Number and your Company Name.

Next, the customer makes a tiny decision.

The decision is to answer the phone call or let it go to voicemail.

Live Answer

If your customer answers and say 'Hello', a friendly, if not, recognizable, human voice recording will play to them.

The recording can be created by the store manager or the store owner over the phone.

The message can be about a special event or sale at your store.

Answering Machine

If the call goes to voicemail, the recording will simply be played "after the beep".

When, not if, your customer checks her voicemail, she will hear the recording in its entirety.

This is another benefit of voice broadcasting.

People listen to their voicemail messages. Don't you?

What if...

Ok. that does not sound bad right?

Well, what if a customer still does not want to receive automated phone calls.

The answer is to just add that phone number to your Do Not Call list in your Sigma Voice account.

The Do Not Call phone numbers will never be called again during your calling campaigns.

Of course, there will be an opt-out option for customers that do not want to receive phone calls.

The Result

In many cases, with a well thought out message, the overall response is very positive and can lead to new sales.

Email broadcasting is either free or a very low cost.

Voice broadcasting does have a small cost because our system uses minutes with our phone lines.

We have competitive straightforward pricing.

We feel if the voice broadcast is done well, the new sales will greatly outweigh the related costs.

If your organization is new to this type of proactive customer contact, Sigma Voice can help.

Also, we recommend starting with a small list and making any necessary adjustments moving forward.

Just give it a try and you will be amazed at the results!

Call Broadcast

Just like email broadcasting or sms broadcasting, there are a few things to know about call broadcasting.

Caller ID

This is just the 10 digit phone number that shows on the Caller ID Display. Also, the Caller Name registered with the Local Exchange Carrier may be displayed as well.

This is very important your contacts will be able to see who is calling.


Simply call our dedicated toll free phone number to record your message or upload your recording file from your device into your Sigma Voice account.

Note: Include a clear opt out statement within your recording. "To be removed from our notification list, simply call back and you will be added to our do not call list immediately."

Most recordings are around 30 seconds long but your recording can be up to 5 minutes in length.

Phone List

Your phone lists are YOUR phone lists. Sigma Voice does not share or sell customer information. Review our privacy policy for more information.

File Format

Your phone list can be in any of these popular file formats: Microsoft Excel (.xls or .xlsx), Comma-Separated Values (.csv) or Text (.txt).

Phone Number Format

A valid phone number must be 10 digits. If your phone numbers have parentheses and hypens or even a leading 1, that's ok.

Duplicate Phone Numbers

Our system automatically checks for and removes duplicate phone numbers.

This is done so that your contact is only called 1 time per call broadcast.

Additional Contact Fields

In additon to the phone number column, your phone list can also contain a first name and a last name columns as well.

These data fields will be included in your call broadcast report for easy tracking.

Do Not Call List

If you have a list of phone numbers you want to make 100% sure you do not call, this do not call list can be uploaded into your do not call list.


Most of your phone calls will be answered by a human or a machine. A small percentage will be busy or no answer.


Your contact's phone is ringing.

She looks at the Caller ID display and recognizes your phone number.

She answers and says "Hello?"

Almost immediately, your recording will start playing.


So your contact is not available.

Don't worry! After the answering machine greeting plays and of course the famous BEEP, your recording will play.

All the while, the answering machine will record your important message.

Sometime later, your contact will play her messages and listen to your recording.


The Call Broadcast Report is available in your account on a real-time basis. It is also emailed to you upon completion of the call broadcast. The columns are below.
