Why

Why Are People Switching From Klenty to Outbound System

Klenty only works when you have SDRs dialing and sending every day. Teams choose Outbound System to get the meetings without building that team.

Built for Teams Without SDRs

Klenty is designed for phone-first SDR teams to run, so it assumes you have reps dialing and sending every day. Outbound System is the team. We handle targeting, copy, sending, calling, and reply handling, and we pass you the prospects who want to talk. You get an outbound program without hiring, training, or managing SDRs.

Lists Built For You

Starter and Growth plans list no contact data credits, so you bring your own lists through CSV uploads or CRM import. Plus includes 4,000 credits. We build and verify your full list using 10+ intent signals, live on the kickoff call. With Outbound System, the list is part of every plan, not a credit balance to track.

AI Calling, Not a Dialer Add-On

Parallel and power dialing is a $45 per user per month add-on in Klenty that helps your reps dial faster. Our AI cold calling makes 250 to 1,000 dials a day for you, with voice agents built in-house that follow your script with 100% adherence. Outbound System places the calls and books the meetings, with no rep on the phone.

Expert-Written Sequences

Our copywriters write every sequence for your buyer and test new angles weekly with A/B tests. Each email uses AI personalization built on buying signals, not basic merge tags, and the copy draws on 10,400+ campaigns we have run. With Outbound System, you approve the messaging and we handle every draft and every revision.

Infrastructure Included

With Klenty you configure sending settings yourself, such as domain tracking, random intervals, and volume control. We set up and manage domains, inboxes, SPF, DKIM, DMARC, and warmup for you, on dedicated U.S. IPs with 100+ Outlook inboxes per campaign. Outbound System keeps your main domain out of cold email entirely.

A Dedicated Account Manager

Every client gets a U.S. account manager, a real-time dashboard, and monthly strategy sessions. Your account manager watches list quality, copy, and deliverability, and walks you through what changed and why in each session. At Outbound System, one person owns your results, so you always know who to call about your campaigns.

What Klenty Costs for a Calling Team

Billing for Klenty is annual or quarterly. For two reps, Growth with calling is $70 per user a month, or $1,680 a year, and Plus is $99 per user a month, or $2,376 a year. The parallel dialer adds $45 per user a month. Add reps' salaries, inboxes, and domains. Outbound System starts at a flat $1,499 a month, with AI calling run for you.

When the People Who Ran It Leave

A web development agency with ten years in business had cold outreach that worked. The founder set up the sending himself with a couple of helpers. When the helpers left, outbound stopped, and he didn't have time to rebuild the senders and track the stats. Outbound System becomes that team, so outbound keeps running when someone leaves.

Why teams comparing Klenty choose Outbound System:

1

You Don't Have SDRs to Run a Dialer

Klenty helps reps call and email faster, which assumes you already have SDRs on the phone every day. If you don't, Outbound System's team and AI calling do the work. We build the list, write the sequences, place the calls, and handle replies, and you show up to the meetings that come out of it.

Your Outbound Depends on One Person

If one SDR or ops person leaves, a tool-based program stalls until you hire and train a replacement. At Outbound System, an account manager, copywriters, and an infrastructure team all work on your campaigns. If someone is out, the rest of the team keeps the sending, the copy, and the reporting on schedule.

Outbound System's voice agents are built in-house and follow your approved script with 100% adherence on every call.

You Want Email Backing Up Your Calls

We run cold email and AI calling from one prospect list, so the people we call have already heard from you. Adding LinkedIn outreach puts a third channel on the same list. Run together, the channels reach your entire market every 60 days, and Outbound System's three channels produce 2 to 3 times the meetings of email alone.

"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..."
