The verdict in three sentences
For a Singapore B2B services firm emailing 5,000 contacts, a solid launch in 2026 costs 2,850 to 9,750 SGD, then 40 to 250 SGD a month in tooling plus follow-up time. The most underestimated lines are list cleaning and domain authentication: skip them and 20 to 40% of emails land in spam, wasting the rest of the budget. Under the PDPA, consent and Do Not Call checks are also part of the job, not optional extras.
The sample quote, line by line
The example: a Singapore IT managed services firm (30 staff) re-engaging 5,000 contacts (clients, past prospects, event attendees) with a 5 email sequence. 2026 estimates, day rate 700 to 1,000 SGD.
| Line item | Days | 2026 range (SGD) | Deliverable |
|---|---|---|---|
| Scoping: segments, offer, calendar | 0.5 to 1 | 350 to 1,000 | Segments, targets, KPIs |
| List cleaning and segmentation (5,000 contacts) | 1 to 1.5 | 500 to 1,400 | Duplicates removed, addresses verified, consent status flagged |
| Domain authentication (SPF, DKIM, DMARC) and warm-up | 0.5 | 350 to 600 | Domain compliant with mailbox provider rules |
| Responsive email template | 0.5 to 1 | 400 to 900 | Reusable branded template |
| Copywriting, 3 to 6 emails | 1.5 to 3 | 750 to 3,600 (250 to 600 per email) | Subject lines, copy, CTAs, A/B variants |
| Tool setup and automation | 0.5 to 1 | 350 to 1,000 | Sequences, unsubscribe, CRM sync |
| Per campaign report | 0.25 per send | 150 to 250 per report | Opens, clicks, replies, meetings |
| Total launch | 5 to 9 days | 2,850 to 9,750 |
Recurring costs to add
| Recurring item | 2026 range | Note |
|---|---|---|
| Email platform (Brevo, Mailchimp or similar) | 40 to 250 SGD a month | Monthly subscription, public price varies by plan and list size |
| Email verification | 0.005 to 0.015 SGD per address | Before each import |
| New quarterly sequence | 1,000 to 2,500 SGD | 3 to 4 new emails |
| Reporting | 150 to 250 SGD per campaign | |
| List enrichment | 0.30 to 1.50 SGD per contact | When expanding the target |
Deliverability and PDPA requirements to demand
Major mailbox providers now require SPF, DKIM and DMARC plus one click unsubscribe for bulk senders. In Singapore, the PDPA requires consent (or a recognized exception such as deemed consent) for collecting and using personal data, and the Spam Control Act requires a clear sender identity, an accurate subject line and a working unsubscribe for bulk commercial email. Business contact information used purely for business purposes is largely excluded from PDPA consent rules, but your contract should still require documented sources. Demand a dedicated sending subdomain, a bounce rate target under 2% and removal of contacts inactive for over 12 months. PDPC fines can reach 10% of local annual turnover for larger firms, or 1 million SGD.
Mini case study
Illustrative example: Wei Ling, marketing manager at the managed services firm in Paya Lebar, accepts a 6,300 SGD quote (7 days) for a 5 email sequence plus a platform at 110 SGD a month. After cleaning, 4,250 contacts remain valid. With a 36% open rate and a 1.1% positive reply rate across the sequence: 47 replies and 16 meetings. Launch cost per meeting: (6,300 + 3 × 110) / 16 = 414 SGD. With 3 contracts signed at an average of 24,000 SGD, the campaign generates 72,000 SGD of revenue for 6,630 SGD invested over three months.

How much does a B2B email campaign cost in Singapore?

Three to six, spaced 3 to 7 days apart. Beyond six unanswered emails, unsubscribe rates climb sharply.
