 Leslie Stubblefield, Insurance Media Services

CallHub has become my go-to platform for affordable phone canvassing campaigns, voice broadcasts and text message blasts. I used the Voice Broadcast feature in various ways, from inviting people to events to, in one case, contacting almost every household in a small province to generate leads for people wanting more information about a plebiscite that was taking place.”
