Modern Inbound vs Belkins: Which B2B Lead Gen Agency Fits Your Team?

Both agencies book B2B meetings through outbound outreach, but they operate on fundamentally different models. Modern Inbound runs fully managed cold email campaigns on a quarterly retainer. Belkins offers multi-channel outreach with a heavier emphasis on LinkedIn and phone alongside email. Your choice depends on budget structure, channel preferences, and team size.

Quick Verdict: Modern Inbound vs Belkins

Pricing and Contract Structure

Modern Inbound charges a flat quarterly retainer that bundles everything: domains, mailboxes, verified leads, copywriting, campaign management, and lead delivery. There are no per-lead fees or hidden costs. Belkins uses custom project-based pricing that varies by campaign scope, channel mix, and team allocation. Most Belkins engagements start at a higher monthly minimum due to their multi-channel approach and dedicated SDR assignments.

For teams with predictable budgets under $5K/month, Modern Inbound offers more cost certainty. Belkins tends to fit mid-market companies with $8K-$15K+ monthly outbound budgets who want phone and LinkedIn layered on top of email.

Service Scope and Channel Coverage

Modern Inbound is a cold-email-first agency. They own the entire email infrastructure: 7-30 secondary domains per client, SPF/DKIM/DMARC configuration, 14-day warmup cycles, and 20 emails per mailbox per day sending limits. Every campaign runs plain-text-first sequences designed to land in primary inbox.

Belkins takes a multi-channel approach combining email, LinkedIn outreach, and phone calls. Their team includes dedicated SDRs who handle manual LinkedIn engagement and cold calling alongside automated email sequences. This broader channel mix can work well for prospects who are less responsive to email alone.

Proven Results and Track Record

Modern Inbound has booked over 1,800 B2B meetings across its client portfolio in six months. One Bangalore-based B2B brand received 117 leads in 60 days. A staffing agency client started getting positive replies on day one of campaign launch. The agency maintains zero churn across 18 active clients at peak capacity.

Belkins reports having worked with 1,000+ clients across various industries. They emphasize their appointment-setting track record and maintain a team of 200+ SDRs and researchers. Their case studies typically highlight enterprise and mid-market wins in SaaS, professional services, and technology sectors.

Onboarding and Time to First Results

Modern Inbound onboarding follows a structured process: signed agreement, ICP definition, domain procurement and DNS setup, 14-day warmup, then campaign launch. Most clients see first positive replies within 1-3 days of launch. The entire ramp takes about 3 weeks from contract signing.

Belkins onboarding involves strategy sessions, ICP workshops, SDR assignment and training, and multi-channel playbook development. Due to the broader scope, initial setup typically takes 4-6 weeks before full campaign velocity is reached.

Which Agency Fits Your Team?

Choose Modern Inbound if: You want a focused cold email engine with predictable retainer pricing, founder-level WhatsApp access, and you are a recruitment agency, B2B SaaS company, consulting firm, or HR tech company looking for meetings without managing infrastructure.

Choose Belkins if: You need multi-channel outreach (email + LinkedIn + phone), have a larger monthly outbound budget ($8K+), and want a dedicated SDR team handling personalized touches across channels.
