A full-time B2B lead generation specialist, cold outreach strategist, and founder of Convo Digital LLC.
I started Convo Digital and Mizanur's Guide to share battle-tested B2B prospecting playbooks, high-reply cold email frameworks, and automated outbound systems that turn research into real revenue.
Helping B2B teams, founders, and agencies generate qualified prospects and build predictable revenue systems.
Hand-verified prospect lists targeted by exact ICP, firmographic filters, tech stack, and intent signals. Every contact is 100% verified with zero bounce guarantees.
Personalized, conversational multi-touch campaigns crafted to cut through noisy inboxes and start genuine business conversations without risking your primary domain reputation.
Custom n8n workflows, CRM pipelines, automated data enrichment, and webhook integrations that eliminate manual data entry and keep your sales team focused on closing.
From a solo freelancer on Upwork and Fiverr to building Convo Digital and helping 50+ B2B companies scale their outbound revenue. Here is how our story evolved:

Clients Served
Started providing B2B web research, prospect list building, and email marketing for international startups and agencies.
Turned freelance consulting into a full-service agency with repeatable systems, dedicated researchers, and client outreach campaigns.
Delivered over 500,000 human-verified leads and supported outbound campaigns for SaaS startups across North America and Europe.
Integrated autonomous AI enrichment, webhook pipelines, and modern CRM synchronization to eliminate manual data entry.
Expanding into product development with Sublix (subscription & trial reminders) and PostNow (LinkedIn content workflows).
Most outbound outreach today is completely broken. Founders purchase outdated databases of 10,000 generic emails, blast impersonal templates, burn their primary company domains, and get zero replies.
I built Convo Digital on the fundamental belief that outreach must be rooted in deep research, verified data, and real human relevance.
Outreach Performance
Client Campaign Stats
I graduated in Electrical and Electronics Engineering from North Bengal International University and Electronic Technology from Rajshahi Polytechnic Institute. That engineering background instilled in me a deep obsession with systems, precision, and repeatable processes.
In 2017, I stepped into the digital marketing and sales world, offering B2B market research, data verification, and email marketing. Over the next 7 years, I worked with international clients across the US, UK, Canada, and Australia as a Top Rated specialist on Fiverr and Upwork.
In 2021, I founded Convo Digital LLC to formalize these methodologies into a full-service outbound engine. My philosophy has always stayed simple: “A short, relevant message to the right person beats a clever message to a random list.”
I regularly share practical outreach breakdowns, email sequences, and list-building strategies.

Outbound Notes
A disciplined, engineering-grade approach to outbound sales development.
We define the exact job titles, company size, tech stack, and trigger events (such as recent funding or hiring) that signal a company is ready to buy.
Instead of buying stale databases, our researchers curate bespoke lists and run multi-layer SMTP and DNS checks to guarantee 99%+ deliverability.
We write short, personal cold sequences that focus on solving urgent pains rather than generic feature dumping, driving real replies and meetings.
Inbox rotation, custom tracking domains, domain health monitors, and automated CRM routing so every warm lead is responded to in minutes.
Only battle-tested platforms that provide reliable data and enterprise uptime.
We're a dedicated team of B2B researchers, data engineers, and outbound strategists committed to driving real pipeline results.
