Cold email reply workload calculator: hours and people needed to answer replies
In short: Type the emails you send, your reply rate, the share needing a written answer and minutes per reply. Get replies a day, hours a month and the people needed, with the math shown. Limit: Every figure is yours; it does not know typical reply rates or handling times.
Replies a month are emails sent times your reply rate. Multiply by the share that need a written answer, then by the minutes one takes, and divide by 60 for hours. Divide hours by working days and by the hours one person gives each day to get people needed. This calculator does it with your numbers.

Your own rate, auto-replies included if you handle them.
The rest are out-of-office or unsubscribes you handle in bulk.
The numbers in the boxes are examples to show how it works. Replace every one with your own; nothing here is a benchmark.
- Replies a month
- 600
- Needing an answer
- 360
- Hours a month
- 24
- People needed
- 0.57
The math, with your numbers
- Replies = 20,000 emails x 3% = 600 (rounded)
- Replies needing an answer = 600 x 60% = 360 (rounded)
- Hours = 360 x 4 minutes / 60 = 24 hours a month
- Per working day = 360 / 21 days = 17.1 replies, 1.1 hours
- People = 1.1 hours a day / 2 hours each = 0.57
Next step
Bounces are not replies, but they still land in the inbox.
Delivery failure notices add to the pile someone has to sort. Checking the list first keeps them out and leaves the time for real replies.

How do I estimate the time cold email replies will take?
- Enter the emails you send in a month and your reply rate per email.
- Enter the share of replies that need a written answer and the minutes one takes you.
- Enter the working days in the month and the hours a day one person gives to replies.
- Read replies a day, hours a month and people needed, and the math.
Example
- You enter
- 20,000 emails a month, a 3% reply rate, 60% of replies needing an answer, 4 minutes each, 21 working days and 2 hours a day per person for replies.
- You get
- 600 replies, 360 needing an answer, 24 hours a month. 17.1 replies and 1.1 hours a working day, 0.57 of a person.
- Limits
- Runs in your browser; nothing is uploaded. Replies are assumed to arrive evenly; every rate and time is yours.
How is the workload worked out?
Replies are emails times the reply rate. The ones needing a person are replies times the share that need an answer. Hours are those replies times minutes each, divided by 60. People needed are hours per working day divided by the hours one person gives to replies each day.
Each line is shown with your numbers filled in, and rounding is only applied to whole replies.
Which replies need a written answer?
Interested replies and questions do. Out-of-office replies, simple unsubscribes and delivery failure notices usually can be handled in bulk or by rules in your inbox. The share is yours to set: look at the last few hundred replies and count.
Unsubscribe requests still have to be acted on, so keep them in the count if you handle them by hand. Reading them in bulk is a faster route; the unsubscribe reply email generator can help with the wording.
What does it change in the plan?
A bigger list means more replies and more hours. If the hours do not fit, you can add people, cut minutes per reply with saved answers, or send less. To work out the sending side, use the meetings target calculator.
Bounces are not replies, but they land in the same inbox as automatic notices. Keeping dead addresses off the list keeps that pile small.

What can’t this tool tell you?
- Every figure is yours; it does not know typical reply rates or handling times.
- It assumes replies arrive evenly across working days, and they often come in waves.
- It does not model back-and-forth threads; count each follow-up reply in the minutes.
- It cannot tell a good reply from a bad one.
Common questions
- What reply rate should I use?
- Your own, from your sending tool, per email sent. The page names no typical rate.
- Does it count auto-replies?
- Only if you include them in your reply rate. Set the share that needs an answer lower to leave them out of the time.
- How long does a reply take?
- Time a few and average them, including finding the thread and any notes you write. The box takes minutes, with halves allowed.
- What does people needed mean?
- Hours of reply work per working day divided by the hours one person gives to replies a day. 0.57 means a little over half of one person's reply time.
- Does it include booking the meeting?
- Only if you include that time in minutes per reply.
- Is my data 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
