How to design a cold email sequence that actually converts
A 4-touch cadence over 14 days — what each step is for, what to write in it, and when to stop.
The most common cold email sequence is wrong in three ways: too long (8+ touches), too aggressive (daily emails), and too templated (every step looks like every other vendor's). Here's a 4-touch sequence that's worked for B2B SaaS, recruiting, and agency outbound across thousands of campaigns.
Touch 1, Day 0: The plain hook.
100 words max. No links. No images. One specific detail about the recipient or their company. One sentence of relevance ("we built X because Y team had Z problem"). One question that's easy to answer in a sentence.
The point of touch 1 is not to close. It's to verify that the address works, the human is real, and the topic is even adjacent to anything they care about. Reply rates of 2–4% are realistic; anything higher and you've either nailed the targeting or are getting auto-replies.
Touch 2, Day 4: The reframe.
If they didn't reply to touch 1, they either (a) didn't see it, (b) saw it and dismissed it as generic, or (c) are interested but busy. Touch 2 addresses (b) and (c) — reframe the problem from a different angle, attach a one-line specific data point, and ask the same kind of low-cost question.
Bad touch 2: "just bumping this up." Good touch 2: "Adjacent to what I sent last week — when [specific company] hit your stage, [specific thing] was the bottleneck. Curious if it's the same for you."
Touch 3, Day 9: The break-up.
The break-up email is the most-replied-to email in most B2B sequences, by far. The format is well-established: short, specific about why this is the last attempt, low-stakes ask, easy out.
"Hadn't heard back so I'll close the file. If it's not the right time, I get it. If you'd rather I follow up in a quarter, just hit 'q' and I'll set a reminder." This converts because it (a) signals you're not going to keep mailing, (b) gives the recipient an easy reply that requires zero commitment, (c) self-selects the genuinely interested.
Touch 4, Day 14: The very-low-stakes nudge.
Optional. Only deploy if your ICP is high-value enough to justify a 4th touch. Format: a single sentence with a useful insight, no ask. "FWIW — [specific data point relevant to their world]. Closing this thread either way."
Stop at 4. Beyond that, every additional touch decreases the marginal reply rate while increasing the spam complaint rate. The math gets bad quickly.
What auto-stops the sequence:
- Recipient replies anything (even an OOO triggers manual review) - Recipient unsubscribes or bounces - Sender's mailbox gets auto-paused for bounce/complaint thresholds - Manual stop via the platform
In BoomSauce, all four are wired by default — reply detection in particular runs at the mailbox level (we read inbound from the same mailbox you sent from), so it catches replies that hit your shared inbox even if your sequence tool didn't see them.
