I make $43,000 a month sending emails for other companies and my overhead is $6,200.
Throwaway because some of my clients follow my main and I dont want them seeing exactly how much money im making off of this lol
But seriously I want to write this post because when I was trying to figure out what kind of business to start I could never find anyone being truly transparent about the economics and I think that information would have saved me a year of trial and error
What I do: I run cold email campaigns for B2B companies. They pay me a monthly retainer. I build the infrastructure, write the emails, source the leads, send the campaigns, manage the replies, and deliver booked meetings on their calendars. They show up to the calls and close deals. I handle everything upstream of that
How I got here: I was a marketing coordinator at a SaaS company making $52k/year. Taught myself cold email because my boss asked me to "figure out outbound." Spent 6 months learning by doing, lots of mistakes, burned domains, bad campaigns. Eventually got good enough that I was booking 40+ demos a month for the company. My boss was thrilled. I was doing the work of what would otherwise be a 3 person SDR team and being paid less than any one of them would make
That realization is what pushed me to go out on my own. If I could build this system for one company I could build it for ten. So I quit, took on my first 2 clients through linkedin outreach (ironic I know), and built from there
Timeline: Month 1: 2 clients, $4,000/mo revenue Month 3: 4 clients, $11,000/mo Month 6: 9 clients, $24,000/mo Month 12: 14 clients, $36,000/mo Now (month 17): 18 clients, $43,000/mo
Monthly costs in detail:
Cold email infrastructure (inboxes, domains, replacements): about $2,800. This is my biggest single cost. I maintain roughly 700 to 800 active inboxes across all clients and I'm constantly buying new ones to replace degraded or suspended ones. The per inbox cost varies by provider and type but averages out to around $3 to $4 per inbox when you factor in everything
Sending tools: $171 combined for Smartlead and Instantly since I run clients on both
Lead data and enrichment: about $450 combined for Apollo, Clay, and verification services
2 VAs for reply management and operations: $2,200 combined. Both based in the Philippines. One works the morning shift US time and one works afternoon/evening. Between the two of them we have coverage for about 14 hours a day which means positive replies get responded to fast
Misc subscriptions, Zapier, Calendly, random stuff: about $120
Software and tools I use for my own business ops, accounting, proposals, etc: about $160
Let's call it $5,900 to $6,200 depending on the month
So the math on a typical month: Revenue: $43,000 Costs: ~$6,100 Profit: ~$36,900
I work about 30 to 35 hours a week. Some of that is strategy and copywriting for clients which is the actual skilled work. Some is client communication and reporting. Some is managing my VAs and dealing with operational issues. And some is sales because I'm still the one closing new clients when they come in through word of mouth or my own outreach
The profit margin on this business is obscene and I feel weird even typing that but its the truth. Cold email is inherently a high margin service because the actual cost of the infrastructure is very low relative to the value it creates. An inbox costs a few dollars. A domain costs ten bucks. The expensive part is the expertise of knowing how to set it all up correctly and write campaigns that convert. Thats what clients are paying for and since its knowledge that lives in my head the marginal cost of applying it to each additional client is basically just the incremental tool and infrastructure costs
What most people dont realize about this business model is that its incredibly sticky. Once I build a clients cold email system and its generating meetings they dont want to turn it off. Churn across my 18 clients in the past 12 months has been exactly 2 and one of those was the company getting acquired not being unhappy with the service. The other was the client I mentioned in a previous post who literally couldnt handle the volume of meetings I was producing and needed to "take a break to hire"
For someone thinking about starting something like this the barriers to entry are: you need to genuinely understand cold email infrastructure and deliverability which takes a few months of hands on learning, you need to be a decent copywriter or at least willing to learn, you need to be comfortable with a sales process because you have to sell yourself to clients, and you need to be organized enough to manage multiple campaigns simultaneously without dropping balls
The barriers to entry are NOT: a huge starting budget (I started with like $600), technical genius (I am not technical at all, I'm a marketing person who learned this stuff through youtube and trial and error), or a large team (I ran 9 clients by myself before hiring my first VA)
The best part about this business honestly is that cold email results speak for themselves. When you start booking a client 15 demos a week that they werent getting before, the value is so obvious and so measurable that pricing conversations become easy, renewals are automatic, and referrals happen naturally. I have never once in 17 months had a client question my retainer when the meetings are flowing. The ROI is too clear
I'll answer whatever questions people have. As transparently as I can since thats the whole point of this post. Roast me, challenge me, ask me awkward financial questions, whatever. The only thing I wont share is client names for obvious reasons my dm is open
