TL;DR
The best follow-up adds new value — a relevant case study, a data point, or a different angle on the problem — rather than asking 'just checking in.' Send 3–5 follow-ups over 3–4 weeks. The breakup email ('I won't reach out again after this') often has the highest reply rate in the entire sequence.
"Just checking in" is the most useless phrase in sales. Never send it. Every follow-up should give them a reason to reply that didn't exist before.
The 5-email sequence structure:
Email 1 (Day 1): The hook. 80 words, specific, direct. As covered above.
Email 2 (Day 4–5): Add a new data point or reframe. 100 words max. "One stat I forgot to mention: teams using structured enablement see 40% lower quota attainment variance in the first 90 days. The variance is actually the bigger problem than average ramp time." Give them something new to chew on.
Email 3 (Day 8–10): Social proof. Share a one-paragraph mini case study of a similar company. "We helped [similar company] do X in Y timeframe — worth a quick read if you're facing a similar situation?"
Email 4 (Day 14–16): Alternative value. Offer something useful without requiring a meeting. A guide, a template, a relevant benchmark. "Putting together our 2025 SDR Benchmarks report — would you want a copy when it's out? No sales call required."
Email 5 (Day 20–22): The breakup. This is often the highest-converting email in the sequence. "I've reached out a few times and haven't heard back — I'll respect your inbox and stop here. If timing isn't right now, hope we can connect when it is. — [Name]" The breakup email converts because it removes pressure. People who felt guilty about not replying finally do.
What not to do: - "Per my last email..." (hostile, passive-aggressive) - "I wanted to follow up on my previous email" (obvious, no value) - Following up every single day (marks you as spam and damages your reputation) - Continuing to follow up after an explicit "not interested" response

Write one sentence that's specifically about them, one sentence on their problem, one on your solution, and one CTA. The email should be under 80 words, reference something real about their company, and ask a yes-or-no question at the end.
How do I find leads for cold email?
Start with Apollo.io or LinkedIn Sales Navigator to build a list from your ICP criteria. Enrich it through Clay or a waterfall of data providers for verified emails. Target trigger events — recent funding, new hires, job postings — to catch companies in active buying moments.
What is a good cold email reply rate?
A good cold email reply rate is 3–8% for a broad ICP campaign and 8–15% for a highly personalized, trigger-event-based campaign. Anything above 15% with meaningful volume is excellent. Below 2% means something fundamental is wrong — ICP, targeting, or the email itself.
How many cold emails should I send per day?
New domains should warm up for 2–4 weeks before sending real campaigns, starting at 10–20 emails/day and capping out at 30–50/day per domain for sustained campaigns. With multiple warmed domains running in rotation, total volume can reach 500–2,000+/day without domain damage.
