How to Plan the Dates of a Cold Email Sequence
Add each gap to the previous step's date, counting either sending days or calendar days. The cold email sequence date calculator does it for up to 12 steps and shows the date, weekday and days from the start for each.
The three counting modes
- Sending days (Monday to Friday). Each gap counts only days when you send. Weekends and no-send dates are skipped.
- Calendar days, move a weekend step. Each gap counts every day, but a step landing on a weekend or no-send date moves to the next sending day.
- Calendar days, no moving. Every day counts and nothing moves.
In the first two modes a start date on a weekend moves to the next sending day. A gap is a whole number from 1 to 60.
Worked example (made-up inputs)
These gaps are invented to show the arithmetic. They are not a recommended cadence. The first email goes out on Monday 16 November 2026, with gaps of 3, 4 and 5 days, and 26 November listed as a no-send date.
| Step | Sending days | Calendar days, moved | Calendar days, not moved |
|---|---|---|---|
| 1 | Mon 16 Nov | Mon 16 Nov | Mon 16 Nov |
| 2 | Thu 19 Nov | Thu 19 Nov | Thu 19 Nov |
| 3 | Wed 25 Nov | Mon 23 Nov | Mon 23 Nov |
| 4 | Thu 3 Dec | Sat 28 Nov moves to Mon 30 Nov | Sat 28 Nov |
In sending-day mode, step 4 counts five days after Wednesday 25 November: Friday 27, Monday 30, Tuesday 1 December, Wednesday 2 and Thursday 3, because 26 November is skipped.
Choosing a mode
Sending days keep the gap meaning what you said it means: three sending days between steps. Calendar days keep a fixed rhythm but can drop a step on a weekend. Pick the mode that matches how your sequencer counts, since the two can disagree. For cadence ideas see cold email follow-up sequences and the best time to send cold email.
What this calculation cannot do
- It does not send or schedule anything.
- It does not know time zones, so a date is the date in your own calendar.
- It does not know holidays unless you enter them.
- Your sequencer may count differently. Check its setting.
Verify before step 1
Bounced and invalid addresses drop out of every number above: a contact that bounces never reads the email, so it can never reply or book. Verify the list before you load it. Upload it on the verify page: the first 100 email checks are free with a Google sign-in, no card. Each address comes back valid, risky or invalid with a reason, and nothing is sent to anyone on the list. For larger or recurring lists, see bulk email verification, list cleaning and pricing.

Common questions
How do I work out the dates of each step in a cold email sequence?
Start from the first send date and add each gap in turn. The cold email sequence date calculator does it for up to 12 steps and shows the weekday and days from the start for each.
What is the difference between sending days and calendar days?
Counting sending days skips Saturdays, Sundays and any no-send dates you list. Counting calendar days counts every day, and can either leave a weekend step where it falls or move it to the next sending day.
How do I handle holidays?
Enter them as no-send dates. In the sending-day mode they are skipped when counting.
Are the example gaps a recommended cadence?
No. They are made-up gaps for the example. Choose your own cadence.
Does this send anything?
No. It only calculates dates. Scheduling happens in your sequencer.
Check your list before you send
Real mailbox checks over SMTP, and nothing is sent to the address. Sign in with Google and your first 100 email checks are free, no card. Plans for bigger lists are on the pricing page.
