11 Best Belkins Alternatives for B2B Cold Email

Key Takeaways

• Belkins is a capable omnichannel agency, but its retainer size pushes many B2B teams toward a lighter, clearer option.
• OutreachBloom ranks first here for teams that want cold email, LinkedIn, and AI-search visibility run together, and yes, OutreachBloom publishes this list.
• SalesBread wins on a stated lead guarantee, CIENCE on enterprise scale, and a self-serve software stack on price.
• Judge every option on booked meetings, not on activity metrics.

Belkins is one of the better-known B2B lead generation agencies, and it earns the reputation. It runs omnichannel outbound, reports over $2 billion in client revenue since 2017, and books 100 to 400 appointments per client yearly.

So why leave? Usually money and fit. Belkins retainers commonly run into the thousands monthly, and the program suits teams wanting a full managed omnichannel motion. Plenty of B2B teams want something lighter, cheaper, or focused on a single channel done well.

This guide ranks 11 Belkins alternatives for cold email, compared on model, channels, pricing, customer fit, and one strength and weakness.

One quick disclosure: OutreachBloom publishes this site, and we ranked ourselves at the top. That’s us at number one.

Wait, doesn’t that make the list suspect? Fair question. So we held every agency to the same test, gave each a real weakness, and flag when a rival fits you better.

One test decides all of it: the calendar. An agency can send 50,000 emails and show beautiful open rates. None of it matters if nobody books time with your team. Every pick below is judged on whether it puts qualified meetings on your calendar.

How We Evaluated These Belkins Alternatives

We ranked each option on five things: what it replaces, the channels it runs, its pricing, its best-fit customer, and its trade-offs. We weighted booked-meeting outcomes and pricing clarity most heavily, since those are where teams get burned.

Competitor facts here come from each company’s own website, verified in July 2026. Our own details are current as of July 2026. Where an agency does not publish pricing, we say so rather than guess.

1. OutreachBloom: Best for B2B Teams That Want Outreach and AI Visibility Together

Quick take: OutreachBloom runs cold email, LinkedIn, and Reddit outreach. It also gets your brand cited in AI search results, so buyers find you in inboxes and inside ChatGPT.

OutreachBloom is a B2B outbound agency that has served 1,000-plus brands since 2010, led by CEO Jayson DeMers. We build the lists, write the messaging, run the sending, and manage replies. Your team shows up to booked calls instead of babysitting tools.

The piece that sets us apart is AI-search visibility. Buyers now ask ChatGPT, Claude, and Gemini for recommendations before they ever open an email. We work to make your brand the one those tools name. In one program, a client moved from 14% to 61% AI visibility over 90 days.

• Replaces: Belkins’ managed outreach, with AI-search visibility added on top.
• Channels: Cold email, LinkedIn, Reddit, and AI search.
• ICP: B2B SaaS and services companies with 10 to 200 employees.
• Strength: One team runs your outreach and your AI-answer presence together.
• Weakness: We run a monthly model rather than pay-per-meeting, and we fit B2B only, so B2C or local businesses should skip us.

Key features:

• Managed cold email: list building, personalized copy, sending infrastructure, and reply handling.
• LinkedIn outreach through connection requests, DMs, and InMails.
• Reddit community outreach where buyers ask for recommendations.
• AI-search optimization with prompt research, citation building, and visibility reporting.
• Named client work including EmailAnalytics, RevenueBase, and Vulcan7.

Pricing: Monthly and quote-based; see how we stack up against the best cold email agencies for context on rates.

Who should choose OutreachBloom:

• B2B SaaS and services teams that sell to other businesses.
• Founders who want outreach and AI visibility handled by one team.
• Companies with 10 to 200 employees ready to commit to a monthly program.

Limitations: If you only want appointments billed per meeting, a pay-per-meeting shop fits better. We also focus on B2B, so consumer and local businesses should look elsewhere.

2. SalesHive: Best for Predictable Flat-Fee Sales Development

Quick take: SalesHive is a US-based B2B sales agency that books meetings through cold calling and email. It runs on its own AI platform at a flat monthly fee.

SalesHive positions itself as the AI-powered sales agency with your “pipeline, predictably full.” It reports 129,000-plus qualified meetings booked and $2.5 billion in pipeline generated across 2,285 clients, with 100% US-based SDRs. Listed clients include Shopify, Siemens, and Otter.ai.

Its model leans on calling and email rather than social selling, which suits teams whose buyers still answer the phone.

• Replaces: Belkins’ appointment setting, on a flatter and more predictable fee.
• Channels: Cold calling and email, with CRM sync and intent signals.
• ICP: B2B companies across 47-plus industries wanting managed SDR capacity.
• Strength: Flat monthly pricing and US-based callers make budgeting simple.
• Weakness: Lighter on LinkedIn and social selling than omnichannel agencies.

Key features:

• US-based SDR team booking meetings on SalesHive’s own platform.
• Power Dialer for cold calling volume.
• eMod email personalization.
• List building and CRM sync included.

Pricing: Flat monthly fee; SalesHive lists rates on a dedicated pricing page rather than its homepage.

Who should choose SalesHive:

• Teams that want predictable, flat monthly billing.
• Companies whose buyers respond to phone outreach.
• Buyers who prefer 100% US-based callers.

Limitations: SalesHive is calling-and-email led, so teams that need heavy LinkedIn or Reddit presence will find the channel mix narrow.

SalesHive vs OutreachBloom

SalesHive and OutreachBloom both manage outbound for you, but they aim at different buyers. SalesHive is built for phone-and-email pipeline at a flat fee. OutreachBloom pairs email and LinkedIn with AI-search visibility for buyers who research in AI tools first.

Point	SalesHive	OutreachBloom
Lead channels	Calling and email	Email, LinkedIn, Reddit, AI search
Pricing model	Flat monthly fee	Monthly, quote-based
AI-search visibility	No	Yes
Best ICP	Phone-responsive B2B buyers	B2B SaaS and services, 10 to 200 staff

3. CIENCE: Best for Enterprise Teams Needing Per-Meeting Pricing at Scale

Quick take: CIENCE offers a month-to-month, performance-based GTM system with transparent per-meeting pricing. It is built for mid-market and enterprise scale.

CIENCE describes itself as a “Complete GTM System” that is “Month-to-Month” and “Performance-Based.” It reports serving 2,500-plus B2B companies across 250-plus industries, with client logos including Okta, Microsoft, Google, Uber, and Salesforce.

Its scale and data operation make it a fit for larger programs that need thousands of prospects reached with structured reporting.

• Replaces: Belkins’ enterprise outbound, on a per-meeting, month-to-month basis.
• Channels: Cold email, targeted campaigns, physical mail, syndicated content, and ads.
• ICP: Mid-market to enterprise B2B companies.
• Strength: Per-meeting pricing and deep data at enterprise scale.
• Weakness: The scale and setup can feel heavy for a small team.

Key features:

• Outbound and inbound SDR teams with multi-channel outreach.
• Transparent per-meeting pricing with month-to-month contracts.
• B2B, local, and audience data solutions.
• Enterprise GTM setup for large teams.

Pricing: Per-meeting, month-to-month; specific rates are quoted rather than published.

Who should choose CIENCE:

• Mid-market and enterprise teams with high prospect volume.
• Buyers who want to pay per booked meeting.
• Companies that need structured data and reporting at scale.

Limitations: CIENCE is geared to larger programs, so a five-person startup may find it more machine than it needs.

CIENCE vs OutreachBloom

CIENCE and OutreachBloom serve opposite ends of the market. CIENCE is an enterprise-scale, per-meeting operation, while OutreachBloom fits leaner B2B teams that want outreach plus AI-search visibility without an enterprise footprint.

Point	CIENCE	OutreachBloom
Best ICP	Mid-market to enterprise	SMB to mid-market B2B
Pricing model	Per meeting, month-to-month	Monthly, quote-based
AI-search visibility	No	Yes
Channel focus	Multi-channel at volume	Email, LinkedIn, Reddit, AI search

4. Martal Group: Best for a Fractional Outsourced Sales Team

Quick take: Martal Group is an omnichannel B2B sales outsourcing agency. It provides fractional, full-time, or enterprise SDR teams on its own AI platform.

Martal Group calls itself an “AI-powered outbound engine” and an award-winning global agency staffed by SDRs. It offers three team structures and three service tiers, with a monthly funnel that targets 3,000 to 5,000 prospects. One technology case reports 145 booked meetings and 158 SQLs over 27 months.

Martal works well for companies that want an outsourced sales function rather than a single campaign.

• Replaces: Belkins’ managed outbound, structured as a fractional sales team.
• Channels: Email, LinkedIn, and cold calling, guided by an AI platform.
• ICP: Mid-market to enterprise B2B across 24-plus sectors.
• Strength: Flexible fractional-to-enterprise team models.
• Weakness: The mid-market focus fits smaller budgets poorly.

Key features:

• Fractional, full-time, and enterprise sales team options.
• Omnichannel outreach across email, LinkedIn, and calling.
• Intent-based list building with technographic data.
• Tiered services from lead generation to full account management.

Pricing: Quote-based across its team structures and service tiers.

Who should choose Martal Group:

• Companies wanting an outsourced sales team rather than a one-off campaign.
• Mid-market firms scaling pipeline without new headcount.
• Teams in tech, SaaS, and adjacent B2B sectors.

Limitations: Martal targets mid-market and up, so the smallest teams may find the model larger than their needs.

Martal Group vs OutreachBloom

Martal Group sells a fractional sales team, while OutreachBloom sells managed outreach plus AI visibility. Martal fits companies replacing headcount; OutreachBloom fits companies that want channel coverage and AI-answer presence without staffing a full desk.

Point	Martal Group	OutreachBloom
Core offer	Fractional outsourced sales team	Managed outreach plus AI visibility
Best ICP	Mid-market to enterprise	SMB to mid-market B2B
AI-search visibility	No	Yes
Channels	Email, LinkedIn, calling	Email, LinkedIn, Reddit, AI search

5. SalesBread: Best for a Money-Back Lead Guarantee

Quick take: SalesBread promises 20-plus sales-qualified leads per month or your money back, using manual, ultra-personalized LinkedIn and email outreach.

SalesBread’s pitch is “1 lead per day” backed by a money-back guarantee of 20-plus qualified leads monthly. It runs manual personalization instead of AI-generated messaging, and it works LinkedIn and email through Sales Navigator. Reported case numbers include 294 leads for Purple.AI at a 41% reply rate.

The guarantee and the month-to-month terms lower the risk for a team testing outsourced outreach for the first time.

• Replaces: Belkins’ lead generation, with a stated qualified-lead guarantee.
• Channels: LinkedIn and email.
• ICP: Smaller teams wanting a predictable lead floor.
• Strength: A money-back guarantee of 20-plus qualified leads per month.
• Weakness: A narrower channel mix and lower volume by design.

Key features:

• Money-back guarantee of 20-plus SQLs per month.
• Manual, human personalization on every message.
• LinkedIn and email outreach via Sales Navigator.
• Daily lead delivery with month-to-month terms.

Pricing: Month-to-month; rates are quoted rather than published.

Who should choose SalesBread:

• Small teams that want a guaranteed lead floor.
• Buyers who value manual personalization over automation.
• Companies testing outsourced outreach with low commitment.

Limitations: SalesBread skips LinkedIn ads and content, and its manual model produces steady rather than high-volume output.

SalesBread vs OutreachBloom

SalesBread leads with a lead guarantee on two channels, while OutreachBloom runs a wider channel mix plus AI-search visibility. SalesBread is the safer first step for a cautious small team. OutreachBloom is the broader program for teams ready to invest in inbox and AI presence.

Point	SalesBread	OutreachBloom
Guarantee	20-plus SQLs per month or money back	No stated lead guarantee
Channels	LinkedIn and email	Email, LinkedIn, Reddit, AI search
AI-search visibility	No	Yes
Best ICP	Small teams wanting a lead floor	B2B SaaS and services, 10 to 200 staff

6. Nerdy Joe: Best for Pay-Per-Meeting Cold Email on a Budget

Quick take: Nerdy Joe is a cold email agency that charges based on meetings booked rather than emails sent. It is pitched as a cheaper substitute for an SDR hire.

Nerdy Joe promises to “fill your calendar with more sales-qualified leads” and prices around appointments booked. It claims customers pay 5 to 15 times less than the $48,000 to $120,000 cost of an in-house SDR. Its approach centers on research and personalization over volume.

The homepage leans on approach and testimonials, with no published case numbers, so ask for recent results before signing.

• Replaces: Belkins’ cold email, on a pay-per-meeting budget.
• Channels: Cold email.
• ICP: Smaller B2B teams without budget for a dedicated SDR.
• Strength: Pay-for-results pricing tied to booked meetings.
• Weakness: Mostly single-channel, with thin public proof.

Key features:

• Pricing based on meetings or appointments booked.
• Psychographic research for targeted list building.
• Personalization-led messaging that avoids spam tactics.
• No long-term contract.

Pricing: Subscription tied to booked meetings; quoted rather than published.

Who should choose Nerdy Joe:

• Small teams that want to pay per meeting rather than per retainer.
• Founders replacing a first SDR hire.
• Buyers who want email done carefully instead of at spray volume.

Limitations: Nerdy Joe runs mostly on email and publishes little hard data, so its proof is lighter than the larger agencies here.

Nerdy Joe vs OutreachBloom

Nerdy Joe is a focused, budget cold email option, while OutreachBloom is a broader managed program. Nerdy Joe fits a founder replacing one SDR; OutreachBloom fits a team that wants several channels and AI visibility handled together.

Point	Nerdy Joe	OutreachBloom
Pricing model	Pay per meeting	Monthly, quote-based
Channels	Cold email	Email, LinkedIn, Reddit, AI search
AI-search visibility	No	Yes
Best ICP	Budget-conscious small teams	B2B SaaS and services, 10 to 200 staff

7. A Pay-Per-Meeting Agency: Best for Aligning Cost to Outcomes

Quick take: A pay-per-meeting agency charges only for the appointments it books, which ties your spend directly to results.

This model appeals when you want risk sitting with the agency rather than with you. You can read our full breakdown of pay-per-meeting outbound agencies to compare the specific players.

• Replaces: Belkins’ retainer, with cost tied to booked meetings.
• Channels: Usually email and LinkedIn.
• ICP: Teams that want outcome-based billing.
• Strength: You pay for booked meetings rather than activity.
• Weakness: Per-meeting rates can top a retainer once volume climbs, and meeting quality varies.

Who should choose it: teams that want spend aligned to booked meetings and are willing to vet meeting quality closely.

8. A Specialist LinkedIn Agency: Best for Social-Led Pipeline

Quick take: A specialist LinkedIn agency focuses only on social selling, which produces deeper craft on that single channel.

This fits teams whose buyers live on LinkedIn and respond better to a connection than a cold inbox.

• Replaces: Belkins’ LinkedIn motion, run by a dedicated specialist.
• Channels: LinkedIn only.
• ICP: Teams selling to active LinkedIn audiences.
• Strength: Deep expertise on one channel.
• Weakness: A single channel caps reach and volume.

Who should choose it: teams whose buyers are demonstrably active on LinkedIn and who want that channel run expertly.

9. A Cold Email Software Stack: Best for Self-Serve Teams on a Budget

Quick take: A self-serve software stack gives you sending tools, warmup, and data at a fraction of an agency’s cost. You run it yourself.

This is the cheapest path and the most hands-on. You own every step, which means you also own deliverability when it wobbles.

• Replaces: Belkins’ execution, moved in-house on your tools.
• Channels: Email, and LinkedIn if you add a tool.
• ICP: Teams with the time and skill to run outreach themselves.
• Strength: Lowest cost and full control.
• Weakness: You carry the setup, the sending, and the deliverability risk.

Who should choose it: hands-on teams with someone who can own data, sending, and inbox placement.

10. A Boutique Deliverability-First Agency: Best for Inbox Placement

Quick take: A deliverability-first boutique obsesses over inbox placement, which protects the one thing that makes cold email work at all.

When your emails land in spam, nothing else matters, so this model puts placement ahead of volume.

• Replaces: Belkins’ sending, with deliverability as the priority.
• Channels: Email.
• ICP: Teams burned by past deliverability problems.
• Strength: Best-in-class inbox placement.
• Weakness: Smaller scale and a premium price.

Who should choose it: teams recovering from spam-folder problems who need placement fixed before scale.

11. An In-House SDR Team: Best for Full Control of the Motion

Quick take: Building an in-house SDR team gives you complete control and an owned asset. The cost is time and money to ramp.

Hiring your own reps makes sense once outbound is core to the business. You want the knowledge kept in-house. Just plan for the ramp before the results, since it takes months and real budget.

• Replaces: Belkins entirely, with an owned internal team.
• Channels: Whatever you staff and train for.
• ICP: Companies making outbound a permanent core function.
• Strength: Full control and an owned, compounding asset.
• Weakness: Slow, expensive ramp plus ongoing management overhead.

Who should choose it: companies committed to outbound long term with the budget and patience to hire, train, and manage reps.

How to Choose Your Belkins Alternative

Start with the model rather than the logo. Decide whether you want a retainer, a per-meeting fee, or a tool you run yourself. That single choice removes most of this list.

Next, match channels to where your buyers are. If they research in AI tools and read LinkedIn, a calling-led agency fits poorly. The reverse holds for phone-responsive markets.

Then weigh proof and guarantees. SalesBread offers a written lead guarantee, CIENCE and Nerdy Joe tie cost to meetings, and the larger agencies lean on case history. For a wider view of the field, compare the B2B lead generation agencies and the specific cold email agencies before you commit.

What Working With a Cold Email Agency Looks Like, Month to Month

The first month is setup, and it is slower than you want. Expect domain and inbox provisioning, warmup, list building, and messaging drafts before a single send goes out. At OutreachBloom we treat this as non-negotiable, because rushing it burns deliverability you can’t easily win back.

By month two, campaigns are live and replies start landing. This is where the calendar becomes the scoreboard: you should see booked meetings on it, well beyond opens and clicks.

From month three on, the work is iteration. We cut the segments that don’t reply and double down on the ones that do. We report on booked meetings and pipeline over vanity metrics. Ask any agency you consider to report the same way.

Pro Tip

Before you sign, ask the agency to show you a recent client’s booked-meeting count for a comparable ICP. An agency proud of its calendar will share it fast; hesitation tells you what the reporting looks like.

How to Vet a Cold Email Agency Before You Sign

Four questions separate the agencies worth paying from the ones selling activity.

• “How do you protect deliverability?” A vague answer means your emails will end up in spam. Look for specifics on domains, warmup, and monitoring.
• “What exactly do you report?” If the answer centers on opens and sends rather than meetings, the incentives are wrong.
• “Who writes the copy?” Fully automated personalization reads like a template to buyers. Ask how much a human touches.
• “Can I see results for a client like me?” Comparable proof beats a wall of famous logos every time.

Any agency that dodges the deliverability question is telling you how your program ends.

Frequently Asked Questions

What is the best Belkins alternative?

OutreachBloom is the best Belkins alternative for B2B SaaS and services teams. It runs cold email, LinkedIn, and AI-search visibility together on a monthly model. SalesBread is the better pick for a stated qualified-lead guarantee, while CIENCE fits enterprise teams needing per-meeting pricing at scale.

Why look for a Belkins alternative?

Belkins is a strong omnichannel appointment-setting agency. Its retainers commonly run into the thousands per month, and its scope suits larger programs. Smaller B2B teams often want a lighter model, clearer pricing, or a channel mix Belkins does not lead with.

What does Belkins do?

Belkins is a B2B lead generation and appointment-setting agency that runs omnichannel outbound across email, LinkedIn, cold calling, voicemail, and SMS. It reports generating 100 to 400 or more qualified appointments per client per year across 50-plus industries.

How much do Belkins alternatives cost?

Most agency alternatives run on a monthly retainer or a per-meeting fee, and few publish rates. Retainers commonly start in the low thousands per month, and per-meeting models charge only for booked appointments. Self-serve software stacks cost far less but need you to run the program yourself.

Should I pick an agency or a cold email tool instead?

Choose an agency when you want booked meetings without building the process in-house. Choose a tool when you have the time and skill to run sending, data, and deliverability yourself. Agencies cost more but own the outcome, while tools cost less but hand you the work.

Which Belkins alternative is best for the smallest teams?

SalesBread suits the smallest teams because of its money-back guarantee of 20-plus qualified leads per month and its month-to-month terms. Nerdy Joe is another fit for small budgets, since it charges based on meetings booked rather than a large fixed retainer.

Choosing the Right Fit

Belkins is a strong agency, and for a large omnichannel program it may still be the right call. For most B2B teams, though, one of these alternatives delivers the same booked meetings at a model and price that fit better.

Pick the one whose model matches how you want to buy, then hold it to the calendar. Book a strategy call with OutreachBloom if you want cold email, LinkedIn, and AI-search visibility handled by one team.
