10 Best Overloop Alternatives for Sales Teams in 2026

Your last Overloop campaign bounced 23% of its emails. You watched the sender reputation score tick down in real time, did the math on what those credits actually cost, and started searching for something better. That's why you're here.

Overloop's credit system charges $0.28 per prospect on the Starter plan ($69/mo for just 250 credits). Before a single email goes out, you've already spent more per lead than most tools charge for verified, deliverable contacts. The Sortlist acquisition has raised questions about the product roadmap, G2 review activity has noticeably declined, and the data storage limitations make scaling painful.

The case for switching is straightforward.

Our Picks (TL;DR)

• Best for data accuracy: Prospeo - 98% verified emails at ~$0.01/lead, free tier included. Starts at $39/mo.
• Best all-in-one: Apollo.io - massive free tier (10K email credits/mo), 275M+ contacts, built-in sequences. Free to $79/user/mo.
• Best for high-volume sending: Instantly.ai - flat pricing, unlimited email accounts, agency-ready. From $37.60/mo (annual).
• Best for personalization: Lemlist - visual sequence builder, multichannel, 600M+ leads database. From $63/mo (annual).
• Best on a budget: Snov.io - unlimited team seats on Pro, generous credits, recent plan upgrades. From $29.25/mo (annual).

Why People Switch From Overloop

The credit economics are the first thing that breaks. Overloop's Starter plan gives you 250 credits for $69/mo - each consumed when you source a prospect or find an email. That's $0.28 per prospect just to get them into your pipeline. A 5-person team on the Growth plan ($99/user/mo) burns through 500 credits per seat. If you're running any kind of volume, you're either rationing credits mid-month or negotiating Enterprise pricing.

The credit cost wouldn't sting as much if the data was bulletproof. G2 reviews tell a different story. Out of 132 reviews, 8 call out the pricing as expensive, 7 flag missing features, 6 mention slow performance, and 6 report inaccurate email tracking metrics. When your open and click rates aren't reliable, you can't optimize campaigns. You're flying blind.

The Sortlist acquisition adds real risk. While there's no confirmed shutdown, the declining G2 engagement and uncertain product roadmap make long-term commitment a gamble. Overloop also struggles with data storage as businesses grow - a scalability ceiling that hits mid-market teams hard. One Reddit user looking for a replacement needed 2,000+ emails per week with automatic enrollment logic and multi-account support, basic requirements that Overloop's credit caps make expensive to hit.

Then there's the support issue. Overloop's team operates exclusively in European timezone hours. If you're a US-based team running into a Salesforce integration bug at 2 PM EST, you're waiting until the next morning for help. And that Salesforce integration specifically has a reputation for being buggy.

Credit where it's due: Overloop's UI is genuinely intuitive, the AI email writing is solid, and it includes built-in email warmup - something Apollo still doesn't offer. But intuitive UI doesn't matter when you can't afford to source enough prospects to fill a campaign.

How We Evaluated These Overloop Competitors

Every tool was evaluated against six criteria:

• Data accuracy and bounce rates - the single most important factor. A tool with 15% bounce rates will destroy your sender reputation faster than any feature can save it.
• Pricing transparency - no "talk to sales" black boxes. If we can't find the price, we estimate it and say so.
• Scalability - can a 2-person team use it today and a 20-person team use it next year without a painful migration?
• Multichannel capabilities - email-only tools are fine if that's your workflow, but most teams need email + LinkedIn at minimum.
• Integration ecosystem - HubSpot, Salesforce, Pipedrive, and sequencing tools like Instantly and Lemlist.
• G2 ratings weighted by review count - a 4.8 from 30 reviews means less than a 4.5 from 1,000.

We excluded enterprise tools like ZoomInfo and Outreach (starting at $14K+/year) and LinkedIn-only browser extensions that don't match Overloop's feature set. Every tool here is a realistic replacement, not a category stretch.

Overloop Alternatives at a Glance

The Best Tools to Replace Overloop (Detailed Reviews)

Prospeo - Best for Data Accuracy

Most tools compete on features - more channels, more AI, more automation. Prospeo competes on the thing that actually determines whether your campaigns work: data quality.

The database covers 300M+ professional profiles with 143M+ verified emails and 125M+ verified mobile numbers. The headline number is 98% email accuracy, backed by a proprietary email-finding infrastructure and 5-step verification that includes catch-all handling, spam-trap removal, and honeypot filtering. Every record refreshes on a 7-day cycle - the industry average is six weeks. The email finder includes 30+ search filters covering buyer intent, technographics, job changes, and headcount growth signals.

The cost math is what makes this interesting for Overloop refugees. At ~$0.01 per email, you're paying roughly 28x less per prospect than Overloop's Starter plan. The free tier gives you 75 verified emails and 100 Chrome extension credits monthly - enough to test whether the accuracy claims hold up before spending a dollar. One customer, Meritt, tripled their pipeline from $100K to $300K/week and dropped bounce rates from 35% to under 4%.

Use this if: You need a dedicated data layer that feeds into your existing sending tool. Prospeo integrates natively with Instantly, Lemlist, Smartlead, HubSpot, and Salesforce.

Apollo.io - Best All-in-One Platform

Apollo is the consensus #1 Overloop replacement for a reason: it does everything in one place, and the free tier is absurdly generous.

The free plan gives you 10,000 email credits/mo and 5 mobile credits - more than Overloop's paid Starter plan. The Professional tier at $79/user/mo (annual) unlocks A/B testing, multichannel sequences, and an auto-dialer. The database covers 275M+ contacts across 73M+ companies, and the G2 rating (4.7/5 from 9,111 reviews) dwarfs Overloop's 132 reviews.

The catch: Apollo's email bounce rates run 15-20% on some segments. We've seen this consistently across bake-offs. There's no built-in warmup, and the credit system has hidden costs: overages run $0.03-$0.10 per credit. A 5-person team on Professional with typical overages lands around $7,140/year ($4,740 base + ~$2,400 in typical credit overages). Still cheaper than Overloop, but not the bargain the free tier suggests.

Where Apollo beats Overloop: Database depth, free tier, G2 social proof, workflow breadth. Where Overloop had an edge: AI email personalization was genuinely good. Apollo's sequences are more linear and template-driven.

Here's the thing: Apollo is the best all-in-one platform on this list. But most teams don't actually need all-in-one - they need accurate data and a good sending tool. The all-in-one convenience tax is a 15-20% bounce rate.

Instantly.ai - Best for High-Volume Sending

Instantly solved the pricing problem that makes Overloop painful: no per-seat charges. Period.

The Growth plan runs $37.60/mo (annual) for unlimited email accounts and unlimited warmup. Hypergrowth at $77.60/mo (annual) bumps you to 25,000 contacts and 100,000 emails/month. Every plan includes unlimited email accounts - the killer feature for agencies and teams running multi-domain setups.

Instantly's inbox rotation, warmup, and 30-emails-per-inbox-per-day cap keep you out of spam. The 450M+ lead database is solid but lives on a separate pricing tier ($47-$197/mo for data credits), so budget accordingly. An agency running Hypergrowth sending ($77.60/mo annual) plus Hyper lead credits ($197/mo) lands at ~$275/mo total for unlimited accounts and 10,000 lead credits. Still cheaper per-prospect than Overloop, but not the $37.60 headline number.

Skip this if: You need LinkedIn automation built in. Instantly is email-first, full stop.

Lemlist - Best for Personalization

If generic cold emails aren't cutting it, Lemlist is where you go. The real question is whether the personalization features justify the per-seat pricing.

Strengths: The visual sequence builder with branching logic, custom images, and video thumbnails creates campaigns that feel genuinely personalized. The database covers 600M+ leads. The Multichannel Expert plan ($87/mo annual) adds LinkedIn automation, WhatsApp, and a built-in dialer. Email Pro starts at $63/mo (annual) for email-only. The "if opened but didn't reply -> LinkedIn touch -> wait 3 days -> follow-up email" workflows are something Overloop's linear campaigns can't touch.

Watch out for: Multiple LinkedIn accounts. Each one requires its own license - three accounts means three Multichannel Expert subscriptions at $109/mo each ($327/mo). This complaint surfaces on Reddit constantly. Add-on costs also stack: email finding runs $0.01/credit (5 credits per email find), and extra email senders cost $9/mo each.

Snov.io - Best on a Budget

Five people on Snov.io Pro S costs $74.25/mo total. Five people on Overloop Growth costs $495/mo.

That's a 6.7x difference. That single number tells you everything about why Snov.io belongs on this list.

The Starter plan at $29.25/mo (annual) gives you 1,000 credits and 5,000 recipients for solo users. The real value lives on Pro plans and above, where unlimited team seats are included at every tier. A mid-2025 update nearly doubled recipient limits on Pro plans at the same price - Pro S now handles 25,000 recipients for $74.25/mo (annual). The 7-tier email verification system is more thorough than most competitors bother with. G2 rates it 4.5/5 from 467 reviews.

The tradeoffs: Snov.io's 50M+ company profiles is the smallest dedicated database among the tools here that include one. The Starter plan lost team features in the mid-2025 update - it's now solo-use only. And LinkedIn automation is an add-on at $69/mo per slot, which chips away at the budget advantage. But if your priority is getting a team running outbound without per-seat pricing eating your budget, nothing else comes close at this price.

Reply.io - Best for AI-Powered Outreach

Reply.io's standout is Jason AI, an autonomous AI SDR that runs multichannel campaigns. It starts at $500/mo for 1,000 active contacts - expensive, but it's replacing a human SDR, not a software tool.

The standard Email Volume plan starts at $49/mo (annual) for 1,000 active contacts with unlimited mailboxes. Multichannel runs $89/user/mo (annual) and adds LinkedIn, calls, SMS, and WhatsApp. For teams that want AI doing the heavy lifting on outbound, Reply.io is the most ambitious option here.

QuickMail - Best for Email Purists

Waalaxy - Best Budget LinkedIn Automation

Waalaxy's free tier gives you 80 LinkedIn invitations per month. Pro at EUR19/mo (annual) bumps that to 300 invitations with full LinkedIn automation. Email features are locked behind Business at EUR69/mo (annual), and the email finder accuracy runs 60-70% - mediocre at best. Each subscription covers a single LinkedIn account.

For LinkedIn-first prospecting on a budget, it's the obvious starting point. Just don't rely on it for email data.

Expandi - Premium LinkedIn Automation

Expandi runs $99/mo per LinkedIn account ($79 on annual), with cloud-based execution and a dedicated country-based IP per account. The per-account pricing gets brutal at scale - 10 accounts costs $990/mo. And 67% of users report LinkedIn account restriction issues, which is a dealbreaker for teams that can't afford downtime.

Breakcold - Social Selling CRM

Breakcold's unique angle is engaging with prospects' social posts directly from your CRM. CRM Essentials starts at $29/user/mo. No free plan, and advanced features are limited. Interesting for social-first sellers, too niche for most outbound teams.

The Data Accuracy Problem That Kills Campaigns

Every article comparing Overloop competitors focuses on features, UI, and pricing. Almost none ask the question that actually determines whether your campaigns work: what's the bounce rate?

Here's what we've seen across dozens of tool evaluations: most all-in-one platforms deliver email accuracy in the 70-87% range. That means 13-30% of your emails either bounce or hit dead inboxes.

A 15% bounce rate doesn't just waste credits - it actively damages your sender reputation. Once your domain gets flagged, even your good emails start landing in spam. You're not just losing the bounced prospects; you're losing deliverability on every future campaign.

This is the "all-in-one compromise" that nobody wants to talk about. Tools that bolt on a database as an afterthought - because their core product is sequences or LinkedIn automation - can't match a platform built specifically to get data right. Stack Optimize, an agency running client campaigns, maintains deliverability above 94%, bounce rates under 3%, and zero domain flags across all clients. That's not a feature comparison. It's the difference between campaigns that work and campaigns that burn your domain.

The smart move isn't picking one all-in-one tool and hoping the data is good enough. It's picking a dedicated data layer with verified accuracy and feeding it into whatever sending tool fits your workflow. If your average deal size is modest - say under $10K - you probably don't need a $79/seat all-in-one platform. You need clean data and a $37/mo sending tool.

Which Alternative Is Right for You?

Your best Overloop alternative depends on your team size, budget, and workflow. Here's how to decide:

Solo founder on a budget: Start with Snov.io Starter ($29.25/mo) for outreach. Total cost: under $30/mo with 1,000 credits. Add a free email verification tier to keep bounce rates low.

5-person SDR team: Apollo Professional ($79/user/mo) gives you the all-in-one platform, or pair a dedicated data layer with Instantly for better accuracy and deliverability. The data + Instantly stack runs roughly $80-120/mo total versus $395/mo for five Apollo seats - and you'll get cleaner data.

Agency managing 10+ clients: Instantly Hypergrowth ($77.60/mo annual) plus a verified data source. Instantly's unlimited email accounts mean you're not paying per client, and verified data means you're not burning client domains. Budget ~$275/mo total for the full agency stack.

LinkedIn-first prospecting: Waalaxy Pro (EUR19/mo) handles the LinkedIn automation. Pair it with a verified email tool when you need to move conversations to email - Waalaxy's 60-70% email accuracy isn't reliable enough on its own.

Email-only, high personalization: Lemlist Multichannel Expert ($87/mo annual) is the clear winner. The visual branching sequences and custom image personalization are unmatched.

Cheapest possible start: QuickMail Starter at $9/mo for sending. You're running cold email for under $10/mo - add a free data tier when you need verified contacts.

FAQ

Is Overloop shutting down?

No confirmed shutdown, but Overloop's acquisition by Sortlist and declining G2 review activity raise questions about long-term product investment. If you're evaluating Overloop today, test alternatives before committing to annual contracts.

Is Overloop the same as Prospect.io?

Yes - Prospect.io rebranded to Overloop in 2021, shifting from a pure email finder to a multichannel sales engagement platform with LinkedIn automation, AI email writing, and a 450M+ prospect database. If you used Prospect.io years ago, today's Overloop is a fundamentally different tool.

What's the best free alternative to Overloop?

Apollo.io offers the most generous free tier: 10,000 email credits/month, 5 mobile credits, and basic sequences - 40x more monthly credits than Overloop's paid Starter plan. Prospeo's free tier (75 verified emails + 100 Chrome extension credits/month) is smaller but delivers 98% accuracy, making it the better pick if deliverability matters more than volume.

Can I use these tools with my existing CRM?

Yes. Apollo, Lemlist, Snov.io, Reply.io, and Prospeo all integrate natively with HubSpot, Salesforce, and Pipedrive. Most also support Zapier and Make for custom workflows. QuickMail and Instantly connect via Zapier. Waalaxy and Expandi have limited CRM integration since they focus primarily on LinkedIn.

What's the cheapest Overloop alternative for cold email?

QuickMail Starter at $9/mo is the lowest entry point - one sender, 1,000 contacts, 3,000 emails/month with free warmup included. Pair it with Prospeo's free 75 monthly credits and you're running outbound for under $10/mo total.
