Quick answer
InboxArmy and Outbound Pros both work in email, but they solve opposite problems. InboxArmy is a full-service email marketing agency (51-200 employees, Grapevine, Texas) that manages campaigns to your *existing* audience, template production, automation, ESP migration, deliverability audits, and lifecycle email, billed around $50-$100/hour. It suits brands that already have a list and want expert hands running their newsletters, flows, and ESP. Outbound Pros is a founder-led, deliverability-first managed *cold outbound* agency that books meetings with *net-new* prospects who have never heard of you, running email + LinkedIn from one stack (Salesforge with the Primebox unified inbox) on dedicated, owned domains, with transparent live reporting and flexible retainer-plus-performance pricing. If your goal is net-new pipeline from cold prospects, not better marketing to people already on your list, Outbound Pros is the stronger fit.
I'm Jānis, founder of Outbound Pros. We run 36 active outbound campaigns and have shipped 200+ since we started. InboxArmy is a genuinely strong agency in its lane, I'd never tell you otherwise, so this comparison is the honest version: what each does well, where each wins, and which buyer should pick which. The twist here is that we're not really direct competitors. We both touch email, but we sit on opposite sides of the funnel. This is the straight answer on which one your problem actually calls for.

What Is Outbound Pros?
Outbound Pros is a founder-led, deliverability-first managed-outbound agency that runs cold email and LinkedIn campaigns for B2B companies from a single coordinated stack. We run 36 active client campaigns and have shipped 200+ since starting. Our job is the opposite end of the funnel from a marketing-email agency: we start conversations with net-new prospects who have never heard of you, then book qualified meetings. Instead of an account-management layer between you and the work, you get senior operators who treat cold email as a craft, because on cold sends, deliverability is the difference between a campaign that books meetings and one that lands in spam.
Our stack is modern and AI-native: Salesforge for email + LinkedIn sending (whitelabel tier, with the Primebox unified inbox), Clay for waterfall enrichment and AI personalization, Leadsforge and Apollo for sourcing, and Agent Frank as an optional AI SDR for clients who want it. Every client gets dedicated, owned domain infrastructure with documented SPF/DKIM/DMARC and a proper 4-6 week warm-up, plus a live reporting dashboard and a monthly report that interprets the numbers rather than just dumping them.
Where Does InboxArmy Win?
InboxArmy wins decisively on everything that happens *after* someone is already in your audience. If your problem is "we have a list and our email program is underperforming," InboxArmy is the right call, and I'd tell a prospect that directly. Three specifics matter most:
- Marketing email execution at depth. Campaign management, template production, lifecycle automation, and custom integrations are its core craft. That's a different discipline from cold outbound, and InboxArmy does it full-service with a 51-200-person bench.
- ESP evaluation and migration. If you need to choose a new email platform or migrate off your current one cleanly, InboxArmy runs ESP vendor evaluation and migration as a named service, specialist work most outbound shops don't touch.
- Embedded, flexible resourcing. Clients praise InboxArmy for integrating with internal teams and culture, and it offers dedicated email marketing resources plus audits. The hourly model means you can scope a small audit or a large ongoing program.
If your goal is better email to people who already know you, InboxArmy is built for exactly that.
Where Does Outbound Pros Win?
Outbound Pros wins when the goal is net-new pipeline from cold prospects, a fundamentally different motion from marketing to an existing list, with different infrastructure, deliverability rules, and success metrics.
- Cold deliverability is the specialty, not a checkbox. Sending to people who never opted in is the hardest deliverability problem in email. Every client gets dedicated, owned domains, documented SPF/DKIM/DMARC, and a disciplined 4-6 week warm-up aimed at 85-95% inbox placement, built specifically for cold sends, separate from your main marketing domain so your sender reputation is never at risk.
- Net-new prospecting, end to end. We source, enrich, personalize, send, and manage replies for prospects who aren't on any list yet. That sourcing-through-reply motion is the whole point, it's not something a marketing-email agency is set up to do.
- True multichannel from one inbox. Cold email and LinkedIn run as one coordinated sequence, with replies landing in the Primebox unified inbox instead of being split across tools. That coordination lifts reply rates and stops leads falling through the cracks between channels.
- Transparency by default. You get a live dashboard you can check any time plus a monthly report that interprets volume, quality, funnel, and ROI, what we tested, what the data said, what changes next.
- Modern, AI-native outbound stack. Clay-driven enrichment and personalization, signal-based sourcing, and an optional AI SDR (Agent Frank) mean cold sequences are tailored at scale rather than blasted generically.
- Pricing aligned to meetings. Beyond standard retainers we offer hybrid retainer-plus-performance terms (a base plus a per-meeting fee above a baseline), spend tied directly to the booked meetings that justify cold outbound in the first place.
Pricing: InboxArmy vs Outbound Pros
The two price on different logic because they sell different things. InboxArmy bills roughly $50-$100/hour, an hourly model that fits project-based or variable-scope marketing-email work, where you pay for the hours your newsletters, flows, and audits actually take. Outbound Pros runs $1,500-$10,000/month on a service-based model, with public tiers around $1,500 (startup), $3,000 (growth), and $5,000 (scale), and, for trust-based accounts, a hybrid model of a $2,000-$3,000 base plus $25-$50 per meeting booked above a baseline.
A fair note on value: an hourly rate is hard to compare directly to a monthly retainer, because they're priced for different outcomes. With InboxArmy you're paying for skilled email-marketing hours against your existing program; with Outbound Pros you're paying for a managed system, owned cold infrastructure, sourcing, and senior operators, built to produce booked meetings from net-new prospects. Neither is "cheaper" in the abstract.
Who Should Choose InboxArmy?
Choose InboxArmy if you already have an email audience and want expert hands running it: campaign management, template production, lifecycle automation, deliverability audits on your marketing sends, or a clean ESP migration. It's the right fit for brands across financial services, consumer products, and technology that need a full-service email marketing partner, and the hourly model suits teams that want to scope work flexibly rather than commit to a fixed monthly retainer.
Who Should Choose Outbound Pros?
Choose Outbound Pros if your goal is net-new pipeline, booking meetings with prospects who have never heard of you. That's a different job from marketing to an existing list: it needs dedicated cold infrastructure, owned domains kept separate from your marketing reputation, a sourcing-through-reply motion, and senior operators who treat cold deliverability as the core craft. If you want email and LinkedIn run as one coordinated sequence with replies in a single inbox, transparent live reporting, and incentive-aligned pricing via the hybrid retainer-plus-performance option, Outbound Pros is built for that.
If You're Comparing Options
If you're weighing InboxArmy against Outbound Pros, the honest test is which end of the funnel your problem sits on. Need to market better to an audience you already have, newsletters, flows, ESP work? InboxArmy. Need net-new pipeline from cold prospects who've never heard of you? That's Outbound Pros managed outbound, we onboard in ~21 days, run the full stack from sourcing through reply management on dedicated owned infrastructure, and report monthly on meetings booked, reply rate, and ROI. The conversation starts with what you're trying to achieve and whether cold outbound is even the right channel for it.
Frequently Asked Questions
Is Outbound Pros an InboxArmy alternative?
Partly. They overlap on the word "email" but solve different problems. InboxArmy is a full-service email *marketing* agency that manages campaigns, automation, templates, and ESP work for your existing audience. Outbound Pros is a deliverability-first cold *outbound* agency that books meetings with net-new prospects via coordinated email + LinkedIn on dedicated owned infrastructure. If you're choosing between "improve our marketing email" and "generate net-new pipeline," that decision tells you which one you actually need, and for net-new pipeline, Outbound Pros is the direct fit.
What's the difference between InboxArmy and Outbound Pros?
InboxArmy does marketing email to people already on your list, newsletters, lifecycle flows, automation, audits, and ESP migration. Outbound Pros does cold outbound to people who aren't on any list yet, sourcing, personalization, sending, and reply management to book meetings. The funnel position is the core difference: one nurtures and converts an existing audience, the other creates net-new conversations.
How much do InboxArmy and Outbound Pros cost?
InboxArmy bills roughly $50-$100 per hour on an hourly model. Outbound Pros runs $1,500-$10,000 per month with tiered packages and an optional hybrid retainer-plus-performance structure (a base fee plus a per-meeting fee above a baseline) for aligned incentives.
Can Outbound Pros run my newsletter or marketing automation?
No. Outbound Pros is built for cold outbound, net-new prospecting via email + LinkedIn, not for managing marketing email to your existing audience. If you need newsletters, lifecycle flows, template production, or an ESP migration, InboxArmy is the better fit. If you need booked meetings from cold prospects, Outbound Pros is built for that.
Which one should I pick if I want more meetings booked?
Outbound Pros. Booking meetings with net-new prospects is exactly what cold outbound is for, and it requires dedicated cold infrastructure and a sourcing-through-reply motion. InboxArmy is the stronger choice when the goal is improving how you market to an audience you already have.
