The verdict in three sentences
For a Singapore B2B company, an email campaign produces its first meetings from the third week of sending at best, and a steady flow between week 6 and week 12 of the project (2026 estimate). The critical path is not copywriting but the list of 1,000 to 5,000 contacts and domain warm up, which alone takes 2 to 4 weeks. Plan by phase with a weekly meeting target, check PDPA and Spam Control Act obligations up front, and send from a secondary domain to protect your main one.
Phase by phase plan
Durations below are 2026 market ballparks for a company starting cold outreach with no sending history. Several phases overlap.
| Phase | Duration | What happens | Deliverable |
|---|---|---|---|
| Target and offer scoping | 3 to 5 days | Segments chosen (finance heads at SMEs, regional HQs, logistics firms) | Target sheet and value proposition |
| List building | 1 to 3 weeks | Sourcing, enrichment, address verification | 1,000 to 5,000 verified contacts |
| Technical setup | 2 to 5 days | Secondary domain, SPF, DKIM, DMARC, sending tool | Authenticated domain |
| Domain warm up | 2 to 4 weeks | Volumes ramped from 20 to 150 emails per day per inbox | Stable sender reputation |
| Sequence writing | 4 to 7 days (in parallel) | 3 to 5 emails, subject variants, stop rules | Approved sequence |
| Launch and first replies | Sending weeks 1 to 3 | Batch sends, reply triage | First meetings |
| Optimisation | Sending weeks 4 to 8 | Tests on subjects, segments, offers | Stable reply rate |
In practice, preparation takes 3 to 5 weeks before the first useful send, then 3 to 6 weeks of sending to reach a steady rhythm: hence the 4 to 12 week total.
What to expect, week by week
With a 4 email sequence over 3 weeks and 250 new contacts entering each week, here is a prudent projection.
| Sending week | Cumulative contacts | Reply rate (2026 estimate) | Cumulative positive replies | Cumulative meetings |
|---|---|---|---|---|
| 1 | 250 | 1 % | 1 | 0 |
| 2 | 500 | 1.5 % | 3 | 1 |
| 3 | 750 | 2 % | 6 | 3 |
| 4 | 1,000 | 2.5 % | 10 | 5 |
| 6 | 1,500 | 3 % | 18 | 9 |
| 8 | 2,000 | 3 % | 24 | 12 |
A 1 to 5 % reply rate is a common 2026 ballpark; the table counts positive replies only, about half of all replies, and the latest contacts have not yet received their full sequence.
Budget and causes of delay
| Item or risk | 2026 ballpark or typical delay | How to handle it |
|---|---|---|
| Sending tool and inboxes | 150 to 500 SGD a month | Two or three inboxes on a secondary domain |
| Data enrichment and verification | 200 to 800 SGD a month | Keep bounce rate under 2 % |
| Bought or unverified list | 2 to 4 weeks lost rebuilding reputation | Verify every address before sending |
| Main domain used without warm up | Weeks of poor deliverability | Secondary domain and gradual ramp |
| Internal approval of copy | 1 to 2 weeks | One approver, 48 hour turnaround agreed upfront |
| Sales team unavailable for calls | 1 to 3 weeks of lost momentum | Block meeting slots before launch |
| No CRM sync | Lost replies, missed follow ups | Automatic reply sync |
In Singapore, the PDPA governs personal data such as named business contacts, and the Spam Control Act sets rules for unsolicited commercial email, including clear sender identity and a working unsubscribe facility. Read the PDPC's own guidance before building the list, rather than relying on a tool vendor's summary.
Email goes out to find prospects. To also capture companies already searching for your service in Singapore, Google visibility takes over once the campaign ends.

Mini case study
Illustrative example: Wei Ling, sales director of a 30 person B2B accounting software firm in Singapore, wants 12 qualified meetings before a regional trade event. She plans 4 weeks of preparation (2,000 contact list, secondary domain, warm up) and 8 weeks of sending, 12 weeks in total: she must start in early June to be ready by early September. Budget: about 600 SGD a month for tools and verification, plus 3 internal days a week. If 1 meeting in 4 turns into an annual subscription worth 14,000 SGD, the 12 meetings represent about 42,000 SGD of annual revenue against roughly 1,800 SGD of tooling over three months.
FAQ
How long until the first meeting?
As a 2026 estimate, 5 to 8 weeks from project start: 3 to 5 weeks of preparation, then 2 to 3 weeks of sending. A domain that is already warm saves 2 to 4 weeks.
Can we skip domain warm up?
Not advisable: a new domain sending 500 emails on day one risks the spam folder for weeks. Plan 2 to 4 weeks of gradual ramp up.
How many contacts fill the calendar?
With 3 % replies and half of them positive, 2,000 contacts produce about 30 positive replies and a dozen meetings. A list of 1,000 to 5,000 contacts covers most SMEs.
How many emails per sequence?
3 to 5 emails spaced 3 to 5 days apart. Beyond 5, unsubscribes grow faster than replies.
What if reply rate stays under 1 % after 3 weeks?
Revisit the target first, then the offer, then the subject line, changing one variable at a time on at least 250 contacts.
