How to end a cold email is really a question about two lines: the wrap-up line that follows your ask, and the sign-off word above your name. Everything else in the ending, the call to action and the signature block, is its own discipline with its own rules, and we keep each in its own guide: the ask itself lives in our cold email CTA guide and the block under your name in signature best practices. This article is about the two lines in between, because they are the last thing a prospect reads before deciding whether replying feels easy or expensive.
The advice here is grounded in volume. Our parent agency, Referral Program Pros, has run more than 4,000 outbound campaigns and booked over 7,000 meetings for clients, and GTM Bud was built on that same agency playbook, backed by a reply-rate guarantee of 5 percent positive replies on LinkedIn or 1.5 percent on email, or a full refund. Endings are one of the few parts of a cold email where small wording changes are cheap to test and visibly move replies, which is exactly why they deserve two deliberate lines instead of a reflexive “Looking forward to hearing from you.”
The three-layer ending, and which layers this article owns
Cold email guides, including Woodpecker’s widely referenced framework, converge on the same anatomy for an ending: a wrap-up line, a sign-off phrase, and a signature. It is a useful map, and it makes the division of labor clear. The CTA just above the ending does the asking. The signature does the proving, who you are, that you are real. The two lines in between do something subtler: they set the emotional price of replying.
Here is the core principle, stated once and usable on its own: end a cold email by lowering the cost of responding, not by raising the pressure to respond. A stranger reading your last two lines is deciding between a ten-second reply and the zero-second delete. Pressure phrases, urgency theater, and presumptuous gratitude all raise the perceived price of engaging, because they tell the reader a reply commits them to something. An ending that offers an out, caps the scope of the ask, or hands control back does the opposite, and the reply you get from a prospect who felt free to say “not my area, try our COO” is worth more than the silence you get from one who felt cornered.
The wrap-up line: de-risk, do not re-ask
The wrap-up line sits directly after your CTA, and its one job is to make the ask just above it feel safe. Three patterns do that reliably:
- The out. “If this is not a priority right now, no problem saying so.” Permission to decline paradoxically raises replies, because a no costs the reader nothing and plenty of nos arrive wrapped around referrals and not-yets.
- The scope cap. “Happy to send the two-line summary first.” It shrinks the imagined commitment from a meeting to a glance.
- The control handoff. “Either way, thanks for reading this far.” No demand survives in the sentence, which is precisely what makes answering it feel voluntary.
And three patterns that do the opposite. A second ask, “also, who handles marketing there?”, splits attention and doubles the price of replying. Urgency theater, “I only have two slots left this week”, reads as the template it almost always is. And the classic “Looking forward to hearing from you” quietly asserts an obligation the reader never accepted; it is not fatal, but it spends your last line saying nothing in your favor.
The sign-off: what the data says, and what it does not
The most quoted numbers in this topic come from Boomerang’s analysis of over 350,000 email threads, which found gratitude closings at the top of the reply-rate table: “thanks in advance” around 65.7 percent, “thanks” around 63 percent, and “thank you” around 57.9 percent, against neutral professional closings like “best regards” in the low 50s. Those figures are real, and they are widely reprinted by cold email vendors as if they were cold email benchmarks. They are not. The dataset was opted-in business and community correspondence, where reply rates in the fifties are normal; cold email reply rates live an order of magnitude lower, as our cold email response rate benchmarks lay out. The honest read is that the ordering transfers, gratitude outperforms formality, while the magnitudes do not.
One ranking deserves a cold-specific correction. “Thanks in advance” topped the Boomerang table, but in a first touch to a stranger it claims a yes you have not earned, and that presumption is exactly the register a cold ending should avoid. Our practice across campaigns is plain “Thanks,” “Best,” or a bare first name, matched to the tone of the email above it. What to avoid is clearer than what to pick: “Sincerely” and “To whom it may concern” signal form letter, emoji in a first-touch sign-off reads as unearned familiarity, and anything long enough to need a comma mid-phrase, “Wishing you a wonderful and productive week ahead,” is throat-clearing at the exit.
| Sign-off | First cold touch? | Why |
|---|---|---|
| Thanks / Thank you | Yes | Gratitude signal without presumption |
| Best | Yes | Neutral, short, invisible in a good way |
| First name only | Yes, in plain-text styles | Reads like a real one-to-one note |
| Thanks in advance | Only after a tiny, specific ask | Claims a yes; presumptuous to strangers |
| Sincerely / Regards | Avoid | Form-letter register |
| Cheers | Situational | Fine for casual industries, off elsewhere |
The table’s deeper point: sign-offs mostly lose rather than win. The gap between fine choices is small; the gap between fine and template-flagged is not. Spend the optimization effort on the wrap-up line and the ask, and let the sign-off be quietly unremarkable. One mechanical note that outranks all wording: the ending should leave the email short enough to stay whole, and the length budget it fits inside is covered in how long a cold email should be.
Endings across the sequence: touch two is not touch one
A cold email is almost never one email, and the ending should move as the sequence does. Based on data from over 4,000 outbound campaigns run by our parent agency, Referral Program Pros, the majority of positive replies arrive after the first touch, which means your follow-up endings collectively matter more than your opener’s. The pattern that works: shrink and vary. If touch one ended on an interest question with an out, touch two ends on an offer to send the specific thing, touch three on a different angle entirely, and the final touch on the breakup framing, “if the timing is wrong, I will close the file, and no hard feelings either way,” which converts silence into a decision and a surprising number of decisions into replies. What never works is the same ending re-sent with a new date, because it tells the prospect the sequence is a machine. The full cadence design, spacing, thread choice, and angle changes, lives in our follow-up sequences guide.
A P.S. line can earn a place in one or two touches of a sequence, carrying a genuinely personal note or a zero-pressure pointer at a resource. Once per campaign template, though, is the limit; a P.S. that could sit under every email in the batch is a spam tell, not a touch of charm.
Frequently asked questions about ending a cold email
What is the best sign-off for a cold email?
Short and plain: Thanks, Best, or your first name alone. The Boomerang study of over 350,000 threads found gratitude closings on top, but that was opted-in correspondence, so carry over the ordering, not the percentages. The real rule is negative: avoid anything that smells like a form letter, because the sign-off’s main power is to flag a template.
Should you use “Thanks in advance”?
Only directly after a small, specific ask, and even then plain Thanks is safer in a first touch. It topped the reply-rate table in opted-in email, but to a stranger it presumes a yes that has not been given, which raises the social price of replying instead of lowering it.
What should the last line before the sign-off say?
Something that lowers the cost of replying: an out, a scope cap, or a handoff of control. Its one prohibition is adding a second ask, which belongs to the CTA line and only to the CTA line, per our cold email call to action guide.
Should you put a P.S. in a cold email?
Occasionally, for a personal note or a low-pressure pointer, never as a standing template element. If the P.S. would read identically under every email in the campaign, it has become a spam signal and should be cut.
How should follow-up endings differ from the first touch?
Shrink the ask and change the angle every time: interest question, then an offer to send the resource, then a new angle, then the breakup line that makes silence an acceptable answer. Repeating one ending across a sequence is the fastest way to confirm you are a machine, and it wastes the touches where, in our campaign data, most of the replies actually live.
Make the last two lines do quiet work
Ending a cold email well is undramatic on purpose: a wrap-up line that makes replying cheap, a sign-off nobody notices, and the discipline to vary both across the sequence while the ask keeps shrinking. The senders who get this right do not win because their endings sparkle; they win because nothing in the last two lines gives the reader a reason to flinch.
Writing one great ending is easy. Writing researched, situation-specific emails with disciplined endings for hundreds of prospects a week, and varying them across every follow-up, is the part that consumes a calendar, and it is the part GTM Bud automates: an AI cold email writer built on real prospect research, running inside a done-for-you sending motion, guaranteed at 1.5 percent positive replies on email and 5 percent on LinkedIn, or a full refund.
