Singapore's DNC Registry covers voice calls, SMS, and fax to Singapore numbers, so check every number against the registry before calling or texting. Convention is also to avoid telemarketing calls on Sundays and public holidays. B2B email sits outside the DNC regime but must comply with the Spam Control Act.
Holiday dates are the gazetted 2026 national holidays per market; state and regional holidays vary. Conversions use standard offsets and do not adjust for daylight saving. Runs entirely in your browser.
Why send time matters less than send day
Send time is the most over-discussed and least decisive factor in cold email. A perfectly timed email to the wrong person still fails, and a relevant email at a slightly off hour still works. The signal that does hold up is the day: mid-week beats Monday and Friday, because people are buried on Monday morning and checked out by Friday afternoon.
Within the day, inside working hours beats evenings and weekends for B2B, and early morning or just after lunch tends to catch people between meetings. Beyond that, consistency matters more than the perfect minute; a reliable cadence builds sending reputation, which does more for deliverability than any clever timing trick.
The APAC timezone spread problem
If you are in Singapore emailing prospects in Jakarta, Ho Chi Minh City, Kuala Lumpur, Manila, or Bangkok, "send at 9am" is ambiguous. A send that lands at 9am Singapore time arrives at 8am in Bangkok, Jakarta, and Hanoi. One hour sounds trivial, but it is the difference between landing mid-commute and landing when someone is at their desk, and the gap widens fast once your list includes India, Japan, or Australia.
The fix is to schedule in the recipient's local working hours, not yours. The best time to send is during the recipient's working day, in the recipient's timezone. Everything else is a rounding error next to relevance.
Public holidays and outreach
Public holidays are where APAC scheduling genuinely differs from the US playbook. Each of the six markets in this planner has a different holiday calendar, and the big breaks empty offices for days, not hours: Tet in Vietnam pauses business for a week or more, Hari Raya Aidilfitri reshapes March in Malaysia and Indonesia, and Songkran does the same to mid-April in Thailand. An email sent into a holiday week is buried by the time anyone returns.
Singapore adds a regulatory angle for the rest of your sequence. The DNC Registry covers voice calls, SMS, and fax to Singapore numbers, and the convention is not to make telemarketing calls on Sundays or public holidays. Email is outside the DNC regime, but if your cadence mixes in calls or SMS, the holiday list above is also your do-not-call list. See our Singapore DNC Registry guide for sales teams for the full rules.
How HuntSales schedules sends per contact timezone
This planner tells you when to send; HuntSales does the sending. Set a send window and timezone on each campaign and the sequence only goes out during sensible local hours, never at 2am, with each step spaced to look like a person wrote it. Set it once, then spend your energy on targeting and message, which is where the real gains are.
Stop converting timezones by hand
HuntSales sends from your own mailbox, inside the send windows and timezone you set per campaign, with warmup and suppression built in.

What is the best time to send cold emails in APAC?
Mid-week, inside the recipient's local working hours. Tuesday to Thursday tends to beat Monday and Friday, and early morning or just after lunch catches people between meetings. Send time moves response rates at the margin; relevance and targeting matter far more.
Should I avoid sending cold emails on public holidays?
Yes. An email that lands on a public holiday sits unread under everything that arrives after it, and holiday-adjacent days are often half-days or travel days. Around major breaks like Tet in Vietnam or Hari Raya in Malaysia and Indonesia, pause sequences for the whole week rather than the single gazetted day.
Does Singapore's DNC Registry affect cold email?
No. The DNC Registry covers voice calls, SMS, and fax to Singapore numbers, not email. B2B email to business addresses is governed by the PDPA and the Spam Control Act instead. If your sequence includes calls or SMS to Singapore numbers, check them against the registry first, and follow the convention of not telemarketing on Sundays or public holidays.
How do I handle multiple timezones in one campaign?
Schedule in the recipient's local time, not yours. The APAC spread from GMT+7 to GMT+8 looks small, but a 9am Singapore send is 8am in Jakarta, Bangkok, and Hanoi, and the gap grows once you add India, Japan, or Australia. The clean fix is per-contact timezone scheduling, so each prospect gets the email in their own working hours.
How accurate are the holiday dates in this planner?
They are the gazetted 2026 national public holidays per market, taken from official government announcements. Islamic holiday dates depend on moon sightings and can shift by a day, the Philippines proclaims Eid holidays separately once dates are confirmed, and Malaysia and Indonesia add state holidays and collective leave days on top of the national list.
