Mass calling is a popular mass messaging technology like email and texting that broadcasts a pre-recorded audio message to a list of your contacts without the need to dial each phone number one by one. The Sigma Voice platform makes it easy to launch call blast campaigns from a computer, tablet or even your smartphone fast.
The Sigma Voice system delivers your audio message within a few minutes to all your contacts. After your contacts answer and say hello, your message will be played. Alternatively, Sigma Voice will play your message to your contact's answering machine/voicemail recorder after the beep.
When your message must be received in a timely manner, regular mail and email won't get the job done. Regular mail or snail mail is costly and slow. Email is cheap and fast, but open rates are only about 25% (1 out of 4 people) according to MailChimp.
Sigma Voice offers a web-based mass calling system that allows you to get your pre-recorded audio message to your contacts within minutes. There are no software license fees or phone lines you have to manage.
Also, Sigma Voice provides real-time detailed reports so you can be sure your message was received and heard. You'll even know which calls were answered by a human and which calls were answered by a machine.
Many organizations throughout the US and Canada use Sigma Voice to communicate with their customers, members and employees. Below are a few industries that get a great ROI from running calling campaigns on a weekly, monthly or quarterly basis.
Our online automated calling system is very user-friendly and employs industry-standard SSL Encryption for security and privacy.
Once you've registered for our free trial, just follow the steps below to set up and launch your first mass phone calling campaign.
