Cold email meetings target calculator: how many contacts and inboxes for a meetings goal
In short: Enter a meetings goal and your own rates at each step: show, booking, positive replies, reply and bounce. Get the contacts to load, emails to send and inboxes needed, one line of math per step. Limit: Every rate is your own; a wrong rate gives a wrong plan.
Work backwards from the meetings you want. Divide by the share that show up to get meetings booked, by the share of positive replies that book to get positive replies, then up through the reply rate to the contacts you must email. Add the bounces, count the emails and divide by what an inbox sends. This calculator does it with your rates.

Your own show rate.
Any reply, all steps together.
Sequence steps, assuming nobody leaves early.
The cap you set in your sending tool.
The numbers in the boxes are examples to show how it works. Replace every one with your own; nothing here is a benchmark.
- Contacts to load
- 7,526
- Emails to send
- 22,126
- Emails per sending day
- 1,054
- Inboxes
- 36
The math, with your numbers
- Meetings booked = 20 / 70% show rate = 29 (rounded up)
- Positive replies = 29 / 40% book rate = 73
- Replies = 73 / 25% positive = 292
- Reachable contacts = 292 / 4% reply rate = 7,300
- Contacts to load = 7,300 / (1 - 3% bounce) = 7,526, of which 226 bounce on the first email
- Emails = 7,300 x 3 emails + 226 bounced x 1 = 22,126
- Emails per sending day = 22,126 / 21 days = 1,054
- Inboxes = 1,054 / 30 per inbox = 36 (rounded up)
Next step
7,526 contacts only help if the addresses exist.
The plan assumes 226 bounce. A list that bounces more needs more contacts for the same meetings. Check the addresses first so the bounce rate you plan with is the one you get.

How do I work out how many contacts I need for a meetings target?
- Enter the meetings you want to hold in a month.
- Enter your own rates: booked meetings that happen, positive replies that become a meeting, replies that are positive, and replies per reachable contact.
- Enter the share of your list that bounces, the emails each contact gets, the emails an inbox sends a day and the sending days in the month.
- Read the contacts, emails and inboxes needed, and the math for each step.
Example
- You enter
- A target of 20 meetings held, with 70% showing, 40% of positive replies booking, 25% of replies positive, a 4% reply rate, 3% bounces, 3 emails per contact, 30 emails per inbox a day and 21 sending days.
- You get
- 29 meetings booked, 73 positive replies, 292 replies and 7,300 reachable contacts. Load 7,526 contacts (226 bounce), send 22,126 emails, 1,054 a sending day, from 36 inboxes.
- Limits
- Runs in your browser; nothing is uploaded. Every rate is your own and the example rates are not benchmarks.
How does it work backwards?
Each rate turns the number after it into the number before it. Meetings held divided by the show rate gives meetings booked. Booked divided by the booking rate gives positive replies. Positive replies divided by the positive share gives all replies, and replies divided by the reply rate gives reachable contacts.
Every step is rounded up to a whole number, and each line on the page uses the line above it, so you can follow it with a calculator.
How do bounces change the plan?
Your reply rate is per contact who can receive mail. Contacts who bounce never reply, so the list you load is the reachable contacts divided by one minus the bounce rate. A bounced contact costs one send, because the sequence stops, while a reachable one costs a send for every step.
That is why a list check pays off in this plan: each point of bounce rate you remove is contacts you do not have to buy to hit the same meetings.
Which rates should I use?
Yours. The boxes start with example figures so you can see it work, and none of them is a benchmark. Use the rates from your last few campaigns, and if you have none, try a low and a high guess to see the range the plan covers.
To see what the same activity costs, use the cost per meeting calculator. For how many leads your domains can use in a month, use the leads needed calculator.
Who uses this tool, and for what?
- Cold emailers
- Turn a monthly meetings goal into a list size and an inbox count.
- Agencies
- Quote a client the volume a meetings promise needs before agreeing it.
- Founders
- Check whether a goal is possible with the inboxes you have.
- SDR managers
- Show a team why the list, not just the copy, decides the result.
What can’t this tool tell you?
- Every rate is your own; a wrong rate gives a wrong plan.
- It assumes the same rates all month and nobody leaving a sequence early.
- The inbox count ignores warm-up, so new inboxes need more weeks or more inboxes.
- It says nothing about whether the emails will reach the inbox.
Common questions
- Are the starting numbers typical?
- No. They are examples chosen to show the math. Replace each with a rate from your own campaigns; the page does not claim any of them is average.
- Why divide by the show rate?
- Because you want meetings held, and some booked meetings do not happen. If you count booked meetings as the goal, enter 100 for the show rate.
- What is the reply rate here?
- Replies of any kind per contact who can receive mail, across all steps. It is not the rate per email.
- Does it count follow-ups in the emails?
- Yes. Each reachable contact is counted for every email in the sequence you enter, assuming nobody leaves early, which makes the plan a little high.
- How are inboxes worked out?
- Emails a day divided by what one inbox sends a day, rounded up. The daily cap is your own setting and is not checked against any provider's limits.
- Is anything uploaded?
- No. It runs in your browser.
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.
- Bulk verification with real SMTP mailbox checks
- Hard bounces removed before a send, not discovered after
- Catch-all, disposable and role detection on every row
