Waalaxy vs Prosp: Which Cold Outreach Tool Is Superior?

I've been running outbound for B2B teams since 2019 and have tested all three of these tools on live campaigns. This comparison is for anyone deciding between Salesforge, Waalaxy, and Prosp in 2026, with specific attention to what each tool actually does (and does not) include at the price advertised on its homepage. I've kept it focused on three things: which channels each tool covers, what you actually pay as you scale, and where each one falls short in real use.

This is a three-way comparison because Prosp and Waalaxy show up in the same evaluation set surprisingly often, even though they solve different shapes of problem. Both are LinkedIn-first. Salesforge is in the conversation because it's the platform people land on after either of those two stops scaling. For other head-to-heads in the same category, see the full Salesforge comparisons library, including the deeper Salesforge vs Instantly breakdown.

The real comparison problem

The reason these three tools end up on the same shortlist is that the buyer is usually thinking "I need to do outbound on LinkedIn and email, what should I pick." The honest answer is that only one of these three is actually built to do both. The other two are LinkedIn tools that have either bolted email on at the top tier (Waalaxy) or have not built it at all (Prosp). Buyers find this out two months in, after building sequences they then can't extend to email without leaving the platform.

The other thing I want to flag up front: pricing on all three tools is structured to look cheaper than it actually is. Waalaxy advertises $16/user/month on annual billing, but that plan can't send a single cold email. Prosp advertises $29/account, but that's a volume-tier price you only hit with multiple paid slots on annual billing. Salesforge advertises $40/month, but if you need email infrastructure you'll add Mailforge, Infraforge, or Primeforge on top. I'll break all three down in the pricing section.

Waalaxy overview

Waalaxy is a French LinkedIn automation product launched in 2019 by the team behind ProspectIn. It runs as a Chrome extension that automates LinkedIn invitations, messages, and follow-ups. The pitch is "easy LinkedIn outreach for non-technical users" and the interface lives up to that promise. Setup takes minutes.

The product structure matters here. Waalaxy is LinkedIn-first by design. Email outreach exists only on its top Business plan, and even there the email-finder credits are capped at 500 per month. The Pro and Advanced plans, where most users land, include only 25 email-finder credits per month - effectively LinkedIn-only sequences.

Core features:

• LinkedIn sequences: connection requests, messages, profile visits, follows, and InMails on a single timeline
• 99+ pre-built campaign templates for common outreach scenarios
• Email finder via Dropcontact integration (GDPR-compliant, credits capped by plan)
• AI message writer with GPT-powered suggestions
• Inbox Waalaxy - a reply management tool sold as a separate add-on
• CRM integrations through Zapier and Make (no native CRM connectors)
• Multi-channel sequences with email steps, available only on the Business plan
• Chrome extension as the primary delivery mechanism (a cloud option exists but adds friction)

Pricing (per user, per month, monthly billing - USD shown; Waalaxy serves regional currencies):

• Free: 80 LinkedIn invitations per month, 25 email-finder credits
• Pro: $20/user/mo ($16 on annual) - 300 invitations, 25 email-finder credits, LinkedIn sequences
• Advanced: $40/user/mo ($32 on annual) - 800 invitations, 25 email-finder credits, CRM sync
• Business: $69/user/mo ($55 on annual) - 800 invitations, 500 email-finder credits, multi-channel sequences with email
• Enterprise: Custom pricing for teams

The annual discount is currently 20% with full upfront payment. Note that SalesRobot's January 2026 review documented Waalaxy doubling prices since mid-2024 without adding proportional features, so any annual commitment locks in pricing that may not reflect prior-year value.

Who Waalaxy is built for: Solo operators, recruiters, and small teams who want fast LinkedIn automation and don't need significant email volume. Freelancers and consultants targeting LinkedIn-only motions get the most out of the Advanced plan. The interface is genuinely beginner-friendly.

Known limitations:

• Chrome extension architecture: the standard setup requires your browser to be open with a LinkedIn tab loaded; the cloud option exists but adds an extra layer of management
• Per-seat pricing: a 5-person team on the Business plan costs $345/month at monthly billing - and each user manages one LinkedIn profile
• Email is a side feature: 500 email-finder credits/month on Business is not enough for serious email volume
• No email infrastructure: Waalaxy doesn't sell mailboxes or warm-up. You bring your own and manage deliverability separately
• LinkedIn Inbox is an add-on: reply management is a separately paid product on top of the seat fee
• Pricing history: documented price hikes have roughly doubled costs since mid-2024 without proportional new features (SalesRobot review, January 2026)

What Trustpilot reviewers say about Waalaxy

The Trustpilot reviews trend toward billing disputes and refund-policy complaints. Cancellation friction and unexpected charges show up repeatedly. I'd take that as a signal to read the refund terms carefully before committing to annual billing on any plan.

Prosp overview

Prosp.ai (founded by Yann Dine) is a LinkedIn-only outreach tool built around AI personalization and voice notes. It runs in the cloud, not as a Chrome extension, and gives every connected LinkedIn account a free residential proxy. The headline differentiator is voice cloning - Prosp can clone your voice and send personalized voice notes inside LinkedIn campaigns. That feature is genuinely novel.

I want to be direct about one thing: Prosp does not have email. The Capterra review thread from 2026 explicitly notes "They still haven't added the emailing feature, waiting for that." If you are evaluating Prosp as a multi-channel tool, stop. It is a LinkedIn automation product. Anything you read elsewhere that describes it as multi-channel is either out of date or counting "voice notes inside LinkedIn" as a separate channel. There's a longer breakdown of user experience with Prosp in the full Prosp.ai review.

Core features:

• AI message personalization using prospect profile and social activity
• AI voice notes - clone your voice once, send personalized audio messages at scale
• Lead finder + Chrome extension for pulling leads from LinkedIn searches
• Free residential proxies - one per connected LinkedIn account, to reduce ban risk
• Unified inbox across multiple connected LinkedIn accounts (no email)
• Account rotation for distributing volume across multiple LinkedIn profiles
• Unlimited campaigns and contacts on all tiers (you pay per LinkedIn account, not per contact)

Pricing (per LinkedIn account, per month):

• Monthly billing: $79 (1 account), $59 (volume tier), $29 (higher volume tier)
• Annual billing (35% off): $49 (1 account), $39 (volume), $19 (higher volume)
• Free tier available for testing

Prosp also ran an AppSumo lifetime deal which gave it a 60-day money-back window for many users. That deal has driven much of its review volume on AppSumo.

Who Prosp is built for: Agencies and individual operators running LinkedIn-only outbound at meaningful volume. The per-account pricing scales reasonably for managing multiple client LinkedIn profiles. The voice-note feature is a real differentiator for teams whose prospects respond to audio.

Known limitations:

• No email at all. Not a feature gap, an architectural choice. Multi-channel outbound is not on the table here
• No email infrastructure, no warm-up, no deliverability tooling. Email is simply not part of the product
• Lead list capped at 2,500 contacts per list (per AppSumo product review, May 2025)
• No conditional campaign branching - sequences are linear, not behavior-based
• No AI-generated reply automation. The AI writes outbound messages but doesn't draft replies
• Voice cloning quality is inconsistent. User reviews note the cloned voice can sound robotic and doesn't always match the original speaker
• Account safety reports. Multiple Trustpilot and AppSumo reviewers report LinkedIn account restrictions, even when staying within stated limits
• Trustpilot rating of 3.89/5 across 71 verified users on AppSumo; the Trustpilot page itself shows 13 reviews with multiple billing-related complaints

What Trustpilot reviewers say about Prosp

The most-cited Trustpilot complaint about Prosp is AI message quality: one reviewer documented the AI getting prospect company names wrong in the opening line, which is the kind of error that damages sender reputation rather than building it. Support response time is the second recurring complaint. Read the negative reviews before committing.

Salesforge overview

Salesforge is the multi-channel outreach platform inside the Forge Stack. It runs email and LinkedIn sequences from one dashboard, with unlimited mailboxes on every plan and unlimited LinkedIn senders on the Growth tier. Where Prosp and Waalaxy are LinkedIn tools with limited or no email, Salesforge was built from the start to run both at scale.

What makes Salesforge structurally different is the stack underneath it. The platform isn't trying to be a thin layer on top of someone else's infrastructure. Mailforge (shared IP infrastructure), Infraforge (dedicated IPs), and Primeforge (real Google Workspace and Microsoft 365 mailboxes) all integrate natively, with no Zapier between them. Warmforge handles deliverability monitoring and warm-up at no extra cost on every Salesforge subscription.

Core features:

• Multi-channel sequences combining email and LinkedIn in one workflow, with conditional branching based on prospect behavior
• Unlimited mailboxes on every plan - no per-mailbox fees, no seat caps
• Unlimited LinkedIn senders on the Growth plan, replacing per-seat LinkedIn pricing entirely
• Unlimited workspaces - separate workspace per client, per project, or per brand
• Primebox unified inbox - free with every plan, captures email and LinkedIn replies (and direct mailbox replies, not just sequence replies)
• Free Warmforge warm-up - premium-by-default pool of aged Google Workspace and Microsoft 365 mailboxes, no shared low-quality SMTP
• AI personalization with Overdrive Mode - the AI can pull from prospect website, blog, and LinkedIn posts simultaneously
• Smart mailbox rotation and dynamic IP rotation across connected mailboxes
• Sentiment analysis on incoming replies (positive/neutral/negative tags)
• Multi-language sequences in 20+ languages on the Growth plan
• Salesforge API, MCP server, and Forge CLI for programmatic control
• SOC2 compliant across the entire Forge Stack
• Agent Frank AI SDR available as a separate optional subscription

The Forge Stack context: Salesforge is the outreach layer of a unified stack. Mailforge handles shared-IP infrastructure at $3-2 per mailbox per month. Infraforge handles dedicated-IP infrastructure at $4-3 per mailbox per month, with Woodpecker scaling to 2,500+ mailboxes on it. Primeforge provisions real Google Workspace and Microsoft 365 mailboxes at $4.50-3.50 per mailbox per month. Warmforge runs in the background for free. Leadsforge offers a 500M+ contact database for prospecting. Everything syncs natively.

Pricing:

• Pro: $40/month - 1,000 active contacts, 5,000 emails/month, unlimited mailboxes, 1 LinkedIn sender, 1 user
• Growth: $80/month - 10,000 active contacts, 50,000 emails/month, unlimited mailboxes, unlimited LinkedIn senders, unlimited users, full integrations, API access (note: price is listed as $96/month in some places on the site - verify the live price before subscribing)
• Agent Frank: Separate subscription at $499/month billed quarterly, or $416/month billed annually. Includes 1,000 active contacts. Demo required before purchase
• 2 months free on annual billing for all plans

Who Salesforge is built for (from Salesforge's own published ICP): B2B teams selling products or services with ACVs between $5K and $100K, targeting decision-makers at startups, SMBs, and mid-market companies, with a total addressable market of 3,000+ businesses. Agencies, growth teams, and SDR operations that have outgrown per-seat LinkedIn tools.

Case study anchor: UniteSync reached an 85.26% positive reply rate at a $2.86 CAC using Salesforge, Mailforge, and Warmforge together. ChannelCrawler hit 85.71% positive reply rate on Salesforge plus Infraforge plus Warmforge. These are public case studies on the Salesforge site.

Honest limitations:

• Email infrastructure is not included in the base price. You either connect your own Google/Microsoft mailboxes or add Mailforge, Infraforge, or Primeforge as a separate subscription
• The Pro plan caps you at 1 LinkedIn sender and 1 user. Anything bigger needs the Growth plan
• Several features are gated to Growth: API access, A/B testing, ESP matching, Primebox AI, multi-language sequences, the full integrations library
• Salesforge is explicit about who it's not for: Fortune 500 procurement cycles, six- to seven-figure ACVs, and RFP-driven enterprise sales motions are documented as poor fits on the Salesforge site itself

Head-to-head feature comparison

Multi-channel outreach

This is where the three tools diverge most. The shape of each product determines what's possible:

• Waalaxy: LinkedIn-native with email steps available only on Business plan ($69/user/month). Email-finder credits capped at 500/month on that tier. Multi-channel is technically possible but bottlenecked.
• Prosp: LinkedIn only. No email. The current Capterra review thread explicitly confirms email is not in the product.
• Salesforge: Email and LinkedIn equally weighted in one sequence. Conditional branching between channels based on prospect behavior. Phone outreach is on the roadmap.

If your outbound motion mixes channels, only one of these three is built for that.

Email deliverability and warm-up

Deliverability is a real area of difference, not a marketing one.

• Waalaxy: No native warm-up. You bring your own mailbox and manage deliverability outside the product.
• Prosp: Not applicable - no email.
• Salesforge: Warmforge is included free and unlimited with every subscription. The pool is curated: aged Google Workspace and Microsoft 365 mailboxes only, no recycled inboxes, no questionable SMTP vendors. Heat Score monitoring runs per-mailbox, with 97+ as the healthy target. Free placement testing once per month.

For context, ChannelCrawler hit 85.71% positive reply rate running Salesforge with Infraforge dedicated IPs and Warmforge warm-up. That combination is not reproducible on either competitor here.

AI and personalization

• Waalaxy: GPT-based message suggestions in the campaign builder. Useful for drafting; not deeply personalized.
• Prosp: AI personalization is the product's main differentiator. It pulls from prospect profile data and social activity to craft openers. Voice cloning lets you send personalized audio messages at scale - genuinely novel. Reviewer feedback on output quality is mixed: some say the personalization beats Waalaxy, others report the AI getting basic facts (like company names) wrong in the opening line.
• Salesforge: Overdrive Mode pulls personalization from prospect website, blog posts, and LinkedIn posts simultaneously - a single AI preview can reference multiple sources. AI-drafted replies inside Primebox (Growth plan). Sentiment analysis on every incoming reply. Knowledge Base feature lets the AI reference your uploaded product docs as source of truth.

Inbox management and reply handling

• Waalaxy: The Inbox Waalaxy add-on is a separately paid product on top of any plan. Reply management is a separate purchase.
• Prosp: Unified inbox across multiple LinkedIn accounts is included. No AI-drafted replies. You respond manually to every incoming message.
• Salesforge: Primebox is free with every plan. Unifies email and LinkedIn replies in one view. Catches direct mailbox replies (when prospects reply from a different address than the one contacted). Sentiment-tags every thread. AI-drafted replies in Co-Pilot or Auto-Pilot mode on Growth plan. Available as a mobile app.

Pricing and scalability

This is where the seat-based vs platform-based pricing difference shows up.

• Waalaxy: Per-user pricing. Each LinkedIn account is one seat. A 5-person team on Business is $345/month at monthly billing. The LinkedIn Inbox add-on is an additional separate per-user cost.
• Prosp: Per-LinkedIn-account pricing. The volume discount tiers help scale beyond 1 account, but you still pay per slot. No team-wide flat fee.
• Salesforge: Pro at $40/month has 1 LinkedIn sender and 1 user, so for true team scale you'll land on Growth at $80/month. Growth gives unlimited LinkedIn senders, unlimited mailboxes, unlimited workspaces, and unlimited users. A 5-person team on Growth pays $80/month, not $80 x 5.

Agencies, workspaces, and integrations

• Waalaxy: All team members must be on the same plan tier. CRM sync through Zapier/Make (no native CRM connectors).
• Prosp: Built for agencies with account rotation and unified inbox across multiple LinkedIn profiles, plus free residential proxies per account. No native CRM integrations published.
• Salesforge: Unlimited workspaces (one per client, project, or brand). Native CRM integrations with HubSpot, Salesforce, Pipedrive, Attio, GoHighLevel, folk, and Breakcold. API access on Growth plan. Whitelabel program for agencies with a 20% revenue share. Forge CLI and MCP server for programmatic control. Tool comparisons across the broader ecosystem are catalogued in the Salesforge sales tools directory.

Pricing comparison

A real scenario: a 5-person agency running email and LinkedIn outreach for clients, sending 25,000 emails per month across ~50 mailboxes spread over 10 domains, and managing 5 LinkedIn senders.

• Waalaxy: 5 x Business at $69 = $345/mo for LinkedIn (or $275/mo on annual). The LinkedIn Inbox add-on adds a separate per-user cost. Email is gated to Business and limited to 500 finder credits/user/month, so 2,500/month total - not enough for the scenario. The team would need a separate email sender on top.
• Prosp: 5 LinkedIn accounts at volume tier (~$29-39/account/month annual) = $145-195/mo. Plus a separate email sending tool entirely, because Prosp has no email.
• Salesforge: Growth at $80/mo covers all 5 users, all 50 mailboxes, and unlimited LinkedIn senders. Add 50 Infraforge mailboxes at $3 each = $150/mo. Total: $230/mo, fully integrated, including free Warmforge warm-up across all 50 mailboxes.

Who should use which

You might consider Waalaxy if:

• You're running solo LinkedIn outreach as a freelancer, consultant, or single-operator recruiter
• You're comfortable with Chrome extension architecture and don't mind keeping a LinkedIn tab open
• You want the lowest-friction interface to test LinkedIn automation, and email is a "maybe later" priority
• Your prospect volume on email is small enough that 500 email-finder credits/user/month is plenty

You might consider Prosp if:

• You're an agency or operator running LinkedIn-only outbound at meaningful volume across multiple accounts
• Voice notes are a real channel for your prospect base, not a gimmick
• You don't need email outreach at all - now or in the planned future
• You can tolerate the documented Trustpilot complaints around AI message quality, support response time, and billing

Choose Salesforge if:

• You sell B2B products or services with ACVs between $5K and $100K to startups, SMBs, or mid-market companies (this is Salesforge's published ICP)
• You're running multi-channel outbound and need email and LinkedIn from one platform with real infrastructure underneath
• You've hit the ceiling on per-seat pricing and want unlimited users, unlimited mailboxes, and unlimited LinkedIn senders on a flat fee
• You're an agency or growth team that needs separate workspaces per client and a whitelabel option with a 20% revenue share
• You want premium warm-up included free instead of paying for warm-up separately or relying on low-quality shared pools

One honest note from Salesforge's own published positioning: if you primarily target Fortune 500 companies with six- to seven-figure ACVs and long RFP cycles, Salesforge says explicitly that it's not the right fit. The platform is built for SMB/mid-market motion.

Final verdict

Prosp and Waalaxy solve LinkedIn outbound. Both do parts of that well. Prosp's voice cloning is the most differentiated feature in either product. Waalaxy's interface is the most beginner-friendly LinkedIn automation tool I've used. Neither sells email infrastructure, neither includes premium warm-up, and both have publicly documented support and billing complaints on Trustpilot worth reading before you commit.

For real multi-channel B2B outbound, Salesforge is the stronger choice. At $80/month for the Growth plan you get unlimited users, unlimited LinkedIn senders, unlimited mailboxes, free Warmforge warm-up, and Primebox - and the Forge Stack (Mailforge, Infraforge, Primeforge) sits underneath it natively. A 5-person agency running 50 mailboxes pays around $230/month all-in. Neither Waalaxy nor Prosp offers that price-to-capability ratio at any tier.

One falsifiable benchmark: UniteSync hit an 85.26% positive reply rate at a $2.86 CAC using Salesforge plus Mailforge plus Warmforge. The case study is public on salesforge.ai. ChannelCrawler hit 85.71% on Salesforge plus Infraforge plus Warmforge. Both are reproducible because the infrastructure is part of the product, not bolted on afterward.

FAQ

Is Salesforge better than Waalaxy or Prosp?

For multi-channel B2B outbound across email and LinkedIn at team scale, yes. Salesforge runs both channels natively, includes free Warmforge warm-up, and offers unlimited mailboxes and LinkedIn senders on the Growth plan at $80/month. Waalaxy and Prosp are LinkedIn-first tools - Waalaxy gates email behind its top Business plan, and Prosp doesn't sell email at all. For strictly LinkedIn-only single-operator workflows the comparison is closer; the moment email enters the mix, Salesforge is the only one of the three built for it.

What's the main difference between Salesforge, Waalaxy, and Prosp?

Channels and infrastructure. Salesforge runs email and LinkedIn natively with its own email infrastructure (Mailforge, Infraforge, Primeforge) and free Warmforge warm-up. Waalaxy is LinkedIn-first with email available only on its top Business plan at $69/user/month and limited to 500 email-finder credits per month. Prosp is LinkedIn-only with no email feature at all per its current product roadmap.

Which is cheapest: Salesforge, Waalaxy, or Prosp?

At entry pricing, Waalaxy's Pro plan at $20/user/month ($16 on annual) is the lowest sticker price, but it's LinkedIn-only and capped at 300 invitations per month. Salesforge's Pro at $40/month includes unlimited mailboxes and starts email outreach with 5,000 emails/month. Prosp starts around $29/account/month on annual billing at the volume tier. The honest comparison is at team scale, where Salesforge's flat-fee Growth plan at $80/month covers unlimited users and LinkedIn senders while the others scale per-seat or per-account.

Does Prosp support email outreach?

No. Prosp is a LinkedIn-only automation tool. Reviews on Capterra in 2026 confirm email is still not part of the product. If you need both LinkedIn and email outreach, Prosp is not built for that motion.

Does Waalaxy support cold email at every plan?

No. Waalaxy's Pro and Advanced plans include only 25 email-finder credits per month and don't allow email steps inside sequences. Multi-channel sequences with email require the Business plan at $69/user/month, which itself caps email-finder credits at 500 per month. For serious email volume, you'll need a separate sending tool.

Can I switch from Waalaxy or Prosp to Salesforge easily?

Yes. Salesforge supports CSV upload, Google Sheets connection, and native integrations with HubSpot, Salesforce, Pipedrive, and other CRMs. The 14-day free trial lets you run both platforms in parallel. Salesforge also offers a 30% migration discount for customers switching from Instantly; check with their team for similar terms when migrating from LinkedIn-first tools.

Which tool has the best email deliverability?

Only Salesforge has email deliverability as a built-in part of the platform. Warmforge is included free and unlimited with every subscription, the warm-up pool is curated (no recycled inboxes, no questionable SMTP vendors), and Heat Score monitoring runs per-mailbox. Waalaxy doesn't sell warm-up at all. Prosp doesn't have email at all.

Does Salesforge offer a free trial?

Yes. Salesforge has a 14-day free trial with no credit card required. The trial includes 50 contacts, 100 emails, unlimited mailbox connections, and email warm-up via Warmforge. Sign up at app.salesforge.ai/signup.
