Designed for performance marketers, Phonexa’s email marketing module, E-Delivery, enables you to scale outreach with almost unlimited messages, ESPs, and domains, while our suppression list management tool, Opt-Intel, helps manage email compliance risks, customize opt-out pages, and securely share suppression data with partners.
Both solutions integrate with the rest of Phonexa’s kit, in particular, our flagship products – LMS Sync for managing leads and Call Logic for calls. With this tandem, you can, for instance, automatically follow up on leads or callers who didn’t sell, using remarketing to keep them engaged and, thereby, valuable for buyers.
We have a pretty consultative approach. We don’t just dive in and show people a demo – we’ll spend some time discovering their business and spending, finding out if there is a use case for our software. There’s nothing worse than someone trying to force you down a road of using software that’s not the right fit for you. If Phonexa isn’t right for you, we will be the first people to tell you that. – David Pickard, CEO, Phonexa, from the Pioneering Pay-Per-Call Excellence webinar
