I never set out to become the cold email whisperer at my own startup. Started this compliance SaaS with two engineers and me doing literally everything else. Sales, support, writing docs, making coffee. You know the drill.
By last January we'd hit about $12k MRR through inbound and a couple of LinkedIn posts that caught fire. But inbound plateaued hard around March and I knew I had to figure out outbound or hire someone. Couldn't afford to hire. Still can't, honestly.
So March 2024 I started cold emailing. First month was a catastrophe. Bought a list from Apollo, wrote what I thought were clever emails, sent them from my main domain. Bounce rate hit 11%. Got our domain flagged within two weeks. Lost deliverability on actual customer support emails for days - absolutely terrifying.
Learnt the hard way you need separate domains. Bought three sending domains, set up SPF DKIM DMARC on all of them, started warming them through Mailscale. That warmup took about three weeks before I felt comfortable sending anything real. During that time I researched how others were doing it and realised my list quality was utter garbage.
April I switched to building lists manually through LinkedIn Sales Navigator. Painfully slow but the targeting was sublime. Compliance officers, risk managers, heads of legal at mid-market companies. I'd pull maybe 40-50 prospects a day - not much but all I could manage while running everything else.
For enrichment I started running everything through Prospeo then verifying with MillionVerifier before sending. Email accuracy was around 82-85% from Prospeo which is solid, and after verification my bounce rate dropped to under 2%. Night and day from that first month.
By May I was sending about 35 emails a day across three inboxes through Saleshandy. Reply rate hovered around 2.8%. Not amazing but I was booking 3-4 calls a month and closing about 1 in 4. Our ACV is around $18k so even one deal a month moved the needle.
June and July I tried to scale up. Added two more domains, got to about 60 sends a day. Hit another wall. Writing personalised emails for 60 people a day while also doing product calls and managing support tickets... I was working until midnight most nights. Something had to give.
August I simplified everything. Stopped trying to write unique first lines for every email. Built four templates based on trigger events: new hire in compliance, recent funding, regulatory change in their industry, expansion into EU markets. Each template had maybe three variations. Not as personalised but I could build a day's worth of sends in about 45 minutes instead of three hours.
Reply rate actually went up slightly. Around 3.1%. My theory is the trigger-based approach was more relevant even if less 'personal' than my forced custom first lines.
September was the turning point. Closed three deals in one month. MRR jumped from about $28k to $34k. I remember sitting in my kitchen at 11pm looking at the numbers thinking, ok this actually works. The math works. If I can keep doing this consistently we can get to $50k MRR by spring.
October I added Close CRM because tracking everything in a spreadsheet was becoming insane. $49/mo which felt expensive but it probably saved me five hours a week. Also started using Prospeo for enrichment on all my Sales Nav exports instead of the mixed approach.
November was rough though. Deliverability tanked on two domains. Couldn't figure out why for almost two weeks. Turned out one domain had gotten on a blacklist because I'd been sending from it for seven months straight without rotating. Lesson learned. Burned that domain, bought a replacement, went through warmup again. Lost probably 2-3 weeks of productive sending.
By December I had a better system. Five domains, rotating which ones are active, never sending more than 25 per domain per day. Prospeo handles enrichment, MillionVerifier for cleanup, Saleshandy for sequences. Total monthly cost for all tooling around $380 including domains. That's... manageable.
January 2025 I closed two more deals and we crossed $41k MRR. February another one. Sitting at $47k now with a pipeline that actually looks real for the first time.
The numbers that matter: I send about 80-100 cold emails per day across five domains. Reply rate is 3.2% on average. Positive reply rate (meaning they actually want to talk) is about 1.4%. I book roughly 5-6 calls a month from cold email alone. Close rate on those calls is around 25%. Cost per meeting is somewhere around $70-80 when you factor in all the tooling.
I should probably hire someone to take this over. A dedicated SDR could do 3x my volume and free me up to focus on product and existing customers. But at $47k MRR with three employees the budget is tight and I'm terrified of hiring someone who doesn't understand compliance well enough to write emails that don't sound generic.
So for now it's still me. Every morning 7 to 8:30am building lists and queuing sends. Then the rest of the day doing everything else. It's not sustainable but it's working and I don't want to mess with it yet.
Anyway, that's basically where things stand. A year of doing my own outbound, went from $12k to $47k MRR, most of the growth directly attributable to cold email. Cost me maybe $4,500 total in tooling over the year. And a lot of sleep.
