I spent a full year obsessing over cold outreach. Tried every tactic, every framework, every 'unlock' that gets peddled on LinkedIn. Most of it? garbage. A few things actually paid my mortgage. Here's the honest ranking, least useful to most.
10. optimising subject lines - Wasted 40 hours on A/B testing. Short, long, questions, curiosity gaps. The difference between best and worst? 0.4% reply rate. Stop spending time here.
9. Personalised opening lines - Spent months writing custom openers about prospects' posts or podcasts. Felt clever. Did nothing. Everyone's seen 'loved your post' - brains skip the whole paragraph. Lead with the offer. Replies went up.
8. 'Optimal' send time - Every guide says Tuesday 10am. I tested for two months. Within reason it doesn't matter. Send during business hours and stop overthinking. Embarrassing how much mental energy I burned on this.
7. Long, story-driven emails - Tried 150-word essays with hooks and soft asks because some guru swore by them. Replies tanked. Busy people want the point in under 10 seconds. Went back to 50-70 words and numbers recovered instantly.
6. Video prospecting - Recorded Loom videos for 6 weeks. reply rate identical to a well-written text email, took 8x longer. Only worth it if you've got a dozen dream accounts and time to burn.
5. Multi-channel sequences - Email then LinkedIn then call then email again. Works slightly better than email alone but the operational complexity is a nightmare. Decent for 50 dream accounts. terrible for 2000.
4. following up properly - First thing that actually moved the needle. Sent one email and gave up for 6 months. Then added two follow-ups at 4 and 8 days. Reply rate doubled. Most replies come from follow-up 2 or 3. The first email isn't the campaign - the sequence is.
3. Tight, specific offers for specific segments - Sent the same generic offer to everyone for a year. Then built separate sequences for 50-person vs 500-person companies. Reply rates roughly tripled. generic gets ignored. Specific gets answered.
2. List quality over everything - i spent ages optimising the email instead of the list. Massive mistake. perfect email to a bad list fails. average email to a good list succeeds. now 60% of my time goes on building the list, 15% on writing. Best campaigns all shared one trait: unusually well-targeted lists.
1. Sending infrastructure - The boring stuff nobody wants to talk about. SPF records, secondary domains, proper warmup, low daily volumes. For 8 months i was sending from my main domain and landing in spam. Wrote off my copy as trash and rewrote it 30 times. sorted the infrastructure and the exact same emails went from 1.2% reply rate to over 5%. The only thing that changed was where they landed.
If I could go back, I'd tell myself to spend two weeks on infrastructure before a single hour on copy. The unlock isn't a clever angle - it's the boring stack of fundamentals: good list, specific offer, real follow-ups, reliable delivery. Get those right and a 5/10 email works. Get them wrong and a 10/10 email doesn't.
Ask me anything in the comments - I'm not selling anything, just someone who learned this the hard way.
