Cold email reply rate calculator: per prospect, per email and per step
In short: Sent, bounced, replies and positive replies for up to eight sequence steps give reply rate per prospect and per delivered email, positive share, each step's reply and bounce rate, and which steps earn their place. Limit: It assumes one reply per person; people who reply to several steps are counted more than once.
Cold email reply rate is replies divided by the people you reached, times 100: 42 replies from 958 delivered first emails is 4.38% per prospect. Divided by every delivered email in the sequence it reads lower (1.50% here). Enter each step's sent, bounced and replies to get both, plus each step's share of the replies and its bounce rate.

Sequence steps
The figures loaded are an example. Copy each step’s sent, bounced and replied counts from your sequencer’s campaign report; leave out auto-replies and out-of-office. Positive replies are optional.
4.38%
of the 958 people reached replied (42 replies). Per email sent and delivered, that’s 1.50% across 2,798 emails.

Step by step
- Step 11.98% replied · 0.63% positive · 45% of replies · 4.20% bounced
- Step 21.49% replied · 0.43% positive · 33% of replies · 0.32% bounced
- Step 31.00% replied · 0.22% positive · 21% of replies · 0.22% bounced
Step 1 has the highest reply rate per delivered email (1.98%). More than half the replies came after the first email, so the follow-ups are earning their place.
Step 1 bounced at 2% or more, the lowest line a sending platform publishes. Bounces on step 1 are the list’s fault, not the copy’s: verify the rest of the list before it gets the first email.
Per prospect counts each person once (replies ÷ people who got step 1); per email divides by every delivered email in the sequence, so it always reads lower. Published benchmarks mix the two, so check which one a number uses before comparing.
Next step
A bounce rate this high hurts the replies too. Clean the list before the next batch.
Every bounced address is a prospect who never saw the email, and a bounce rate above a couple of percent pushes the rest of the sequence towards spam. Verifying the next batch before step 1 keeps the sending domain healthy and the reply rate honest.

How do I calculate my cold email reply rate?
- Open the campaign report in your sequencer (Instantly, Smartlead, lemlist, Apollo and others show sent, bounced and replied per step).
- Enter each step's numbers, leaving out auto-replies and out-of-office messages. Positive replies are optional.
- Read the reply rate per prospect and per email, and each step's share of the replies.
- If step 1 bounces at 2% or more, verify the rest of the list before it gets the first email.
Example
- You enter
- A 3-step sequence: 1,000 sent, 42 bounced, 19 replies (6 positive); 940 sent, 3 bounced, 14 replies (4 positive); 905 sent, 2 bounced, 9 replies (2 positive).
- You get
- 42 replies: 4.38% per prospect (of 958 reached) and 1.50% per delivered email (2,798). 28.57% of replies positive. Step 1 brings 45% of replies and bounces at 4.20%, over the 2% line; steps 2 and 3 bounce under 0.4%.
- Limits
- Up to 8 steps; runs in your browser.
How do I calculate cold email reply rate?
Per prospect: replies ÷ people who received the first email × 100. Each person counts once, however many follow-ups they got, so it answers "what share of the people I emailed replied?". Per email: replies ÷ every delivered email in the sequence × 100, which answers "how many emails does a reply cost?". The same campaign gives both, and the per-email figure is always lower once there are follow-ups.
Count real replies only. Auto-replies, out-of-office messages and bounces that land in the inbox inflate the number; most sequencers can filter them. Use delivered, not sent, as the base: a bounced address can't reply.
What is a good cold email reply rate?
Published benchmarks range from under 1% to over 8%, and most of that gap is the formula rather than the copy: some divide by emails, some by prospects, some count auto-replies. Our cold email reply rate benchmarks post lists five studies and what each divides by. Match a benchmark's formula before comparing, or better, compare your own campaigns with each other using the same one.
The positive share tells you more than the raw rate. A 5% reply rate that is mostly "please remove me" is worse than 2% that books meetings, which is why the calculator takes positive replies as an optional column.
Why track bounce rate per step?
Because the first step carries almost all of a list's bounces: follow-ups skip addresses that already bounced. Step 1's bounce rate is the list's bounce rate. Sending platforms pause campaigns above published lines that start at 2%, as the bounce rate calculator sets out, and every bounce is a prospect who never saw the email, so a dirty list lowers the reply rate twice.
Who uses this tool, and for what?
- Cold emailers
- See whether step 3 still earns replies or only adds sends that wear out the domain.
- SDR managers
- Compare reps or campaigns with one formula instead of each sequencer's own definition.
- Agencies
- Report reply rate per prospect and per email side by side, so a client can match it to any benchmark.
- Founders
- Check whether a bad week is the copy or a list with 4% bounces on step 1.
What can’t this tool tell you?
- It assumes one reply per person; people who reply to several steps are counted more than once.
- Per-prospect rate uses step 1's delivered count as the number of people reached.
- It grades bounces against the lowest published platform line, not a mailbox provider limit.
- It can't tell whether the addresses on the list exist.
Common questions
- How do you calculate reply rate?
- Replies ÷ prospects reached × 100 for a per-prospect rate, or replies ÷ delivered emails × 100 for a per-email rate. 42 replies from 958 people reached is 4.38%; across 2,798 delivered emails in a three-step sequence it's 1.50%.
- Should out-of-office replies count?
- No. They say nothing about interest and inflate the rate. Leave them, and other auto-replies, out of the replies you enter.
- How many follow-ups should a cold email sequence have?
- Enough that each step still earns replies. The per-step view shows each step's share of all replies; a step that brings almost none while its bounces and unsubscribes continue is the one to cut.
- Is reply rate per email or per prospect better?
- Per prospect for judging a campaign, because each person counts once. Per email for cost and volume planning. Report which one you use.

Authentication and capacity are half of deliverability.
The other half is who you send to. Every hard bounce counts against the domain and inboxes you are sending from, and nothing in DNS can tell you which addresses on your list are dead.
