Why Outbound System

Why Are People Switching From Apollo.io to Outbound System

Apollo.io is a powerful database. But databases don't book meetings. Outbound System is a fully managed outbound engine that turns data into revenue, without you lifting a finger.

You Get a Team, Not a Tool

Apollo gives you software and says good luck. Outbound System gives you a dedicated strategist, copywriter, and campaign manager who build and run your entire outbound operation. No hiring, no training, no learning curve.

99% Inbox Placement vs. Shared Servers

Apollo sends your emails from shared servers alongside thousands of other users. If anyone on that infrastructure sends spam, your deliverability suffers too. Outbound System runs 350+ dedicated Microsoft Azure inboxes with full authentication.

Pre-Verified Data, No Credit Games

Independent testing shows 22% of Apollo contacts are undeliverable at export. Outbound System verifies every contact before it enters a sequence. No credits, no overages, no surprises.

AI Cold Calling at Scale

Apollo has a basic dialer for manual calling. Outbound System's AI calling makes 250 to 1,000+ dials per day with 100% script adherence and zero downtime. That's the difference between 50 dials and 1,000.

Flat Pricing vs. Credits That Spiral

Apollo charges per user plus credits that expire and cost $0.20 each in overages. A 5-person team realistically spends $30,000 to $40,000 per year. Outbound System is flat monthly pricing with everything included.

44+ Case Studies With Real Revenue

Tools don't publish case studies with revenue data because they can't control the outcome. Outbound System publishes 44+ detailed case studies with exact meetings booked, pipeline generated, and ROI calculated.

10,400+ Campaigns of Performance Data

Every campaign at Outbound System is backed by data from 10,400+ campaigns across every major B2B vertical. Apollo gives you raw data. We give you intelligence that converts.

Multi-Channel From Day One

Apollo's sequencer handles email and basic LinkedIn steps. Outbound System runs cold email, LinkedIn outreach, and AI cold calling as one integrated engine. Clients running all three channels see 2-3x the meetings.

"Because of the processes that Outbound System has developed and put into place, we have been fortunate to have cashflow of multiple six figures per year now. It's been a real game changer type of a gain that we've been fortunate to experience."

Monil Shah

Managing Partner at Tortoise Finance

"Before Outbound System, our deliverability was broken. We weren't landing in inboxes and were losing pipeline across all 35 markets we operate in. Within two weeks of onboarding, we were seeing significantly better results. Since joining, we've generated over 95 leads and built a pipeline that keeps converting months down the road."

Andrew Luedtke

Founder & Managing Partner at AVID Media

"For our business, landing even just one new client per month made this a worthwhile investment. We were easily engaging with 10+ high-intent leads each month (which in the marketing space, is very difficult to do with ice cold leads). I would heavily recommend Outbound and their team."

Will Laub

Co-Owner at Maverick Strategies

"I enjoy working with you personally and the team I have met so far! I think a lot of the value here is the collective wisdom of the Outbound System team to advise and optimize the campaigns. That’s premium is worth is weight in gold."

Derek Merrill

CEO & Founder at Vigur

"Over a year in and we've put up 120+ qualified leads, several of which have turned into long-term association partners. The thing I appreciate most is that Brandon hasn't changed since day one, same guy, same level of care, every single month. Honestly the lowest-maintenance vendor relationship I have right now and one of the highest-ROI."

Tyler Gilham

Sales Director at Lead Marvels

"Outbound Systems' onboarding and ongoing support is great. They were truly thought partners while creating our campaign, and the user interface is sleek. We've generated around 70 meetings so far and have cut down on our time spent messaging significantly"

Ace McGill

CEO & Founder at Value Buddy

"I'm actually extremely impressed with the results so far. It's only been a month into the cold email service with Outbound System, and we've already generated 36 leads in a notoriously difficult market (targeting medical practices). Keep it coming!!"

Randy Young

CEO at Med Profit Lab

"Before Outbound System, we were only getting 3-10 inconsistent leads per month through networking and referrals. In just one month with Outbound System, we've generated about 20 interested responses, booked 15 meetings, and closed 2 new clients. As I always say, doing LinkedIn outreach by yourself is only valuable if your time has no value!"

Clifton Jackson

CEO at FireVibe Web Design

"10 qualified conversations in 6 weeks, targeting is dialed in and we're refining our sales process and offer based on our learnings from Outbound System. So far so good!"

Michael Jaskulsky

Director of Business Development at UnDigital

"Outbound System has been great! I'd highly recommend their LinkedIn lead gen service. We ran 3 profiles with them, and we consistently generated at least 20 positive responses every single month in our local market. So very happy with the team. Great job guys!"

Melanie Shores

Director of Marketing at Modern Mingle

"The results that I got in the first month were WAY higher than the expectation set on the original sales call. I got 64 leads in less than 30 days. I had to pause the system for a while to work the pipeline. Brandon and the rest of the team at Outbound System really have something special here, and I'm speechless..."

Michael Larkin

Founder & President at SC Media Partners

"After getting burned by our previous lead gen provider, Outbound System actually delivered results. Their personalized approach worked when nothing else did. Worth every penny and would recommend to anyone tired of empty promises!"
