Cold email has a bad reputation because most of it is done badly — generic templates, blasted to unverified lists, with no personalization. Done properly, it's still one of the most cost-effective ways to reach new business customers.
1. Start with a verified list
No amount of clever copywriting fixes a bad list. If your bounce rate is high, your emails start landing in spam for everyone — including the good contacts. Verified, recently-updated data is the foundation everything else depends on.
2. Warm up your sending domain
If you're sending from a brand-new domain or one that's never sent bulk email before, ease into it. Start with smaller batches and increase volume gradually over a couple of weeks so mailbox providers learn to trust you.
3. Write subject lines like a person, not a marketer
Short, specific, lowercase-friendly subject lines usually outperform anything that sounds like an ad. "quick question about [company]" beats "Unlock 10x Growth Today!!!" almost every time.
4. Personalize beyond the first name
Mention their industry, a recent company milestone, or a specific pain point relevant to their role. One genuinely relevant detail is worth more than ten generic compliments.
5. Keep it short
Three to five short paragraphs, one clear ask. Long cold emails get skimmed, not read.
6. Lead with their problem, not your product
Open with something relevant to them, not a pitch about how great your company is. Get to why you're emailing quickly.
7. One call to action
Pick a single next step — a reply, a 15-minute call, a link — and ask for that. Multiple asks dilute your response rate.
8. Follow up (politely)
Most replies come from the second or third email in a sequence, not the first. Space follow-ups a few days apart and add new value each time rather than just "checking in."
9. Respect opt-outs immediately
Beyond being the right thing to do, quickly honoring unsubscribe requests protects your sender reputation for every email after it.
10. Track and adjust by segment
Open rates, reply rates, and bounce rates should be tracked by list segment, not just overall — it tells you exactly where to refine your targeting next.
