Respond.io costs US$99 a month for Starter, US$199 for Growth and US$349 for Advanced on monthly billing, which is about S$127, S$255 and S$447 at about S$1.28 per US dollar. Pay yearly and the same plans work out at US$79, US$159 and US$279 a month (about S$101, S$204 and S$357), and Meta's WhatsApp message fees are charged on top of every plan.
Respond.io does not publish a Singapore dollar price list. Every figure below is the US dollar price as listed on respond.io's pricing page in November 2026, check their site for changes. The SGD figures are our own conversion at about S$1.28 per US dollar, so your card statement will differ slightly with the exchange rate and any foreign currency fee your bank adds.
Respond.io plans and prices in Singapore dollars
Respond.io sells four plans. Three have public prices and Enterprise is quoted on request. Yearly billing is advertised as saving up to 20%, and it is paid upfront as one annual charge.
| Plan | Monthly billing | Yearly billing (per month) | Yearly charge upfront | Users included | Extra user |
|---|---|---|---|---|---|
| Starter | US$99 (about S$127) | US$79 (about S$101) | US$948 (about S$1,213) | 5 | US$12 a month (about S$15) |
| Growth | US$199 (about S$255) | US$159 (about S$204) | US$1,908 (about S$2,442) | 10 | US$20 a month (about S$26) |
| Advanced | US$349 (about S$447) | US$279 (about S$357) | US$3,348 (about S$4,285) | 10 | US$24 a month (about S$31) |
| Enterprise | Not listed publicly | Not listed publicly | Not listed publicly | Custom | Not listed publicly |
The free trial runs for 7 days with no credit card, on Growth features for 5 users and 1,000 contacts, with broadcasts excluded. A 28-day onboarding programme is shown as an add-on, and its price is not listed publicly.
What each plan includes, and what Starter leaves out
The headline price matters less than which plan you actually need. On the pricing page, Starter lists team and custom inboxes, the mobile app, AI Prompt and AI Assist, basic reports and two-factor authentication. Broadcasts, workflow automation and AI Agents are listed from Growth upward, and they are not listed under Starter.
That has a practical effect for a Singapore business. If you want to send a promotional WhatsApp message to your customer list, the plan to budget for is Growth at US$199 a month (about S$255), not Starter at US$99. Advanced adds incoming and outgoing webhooks, single sign-on, multiple workspaces and custom channels, which mostly matter to larger teams with developers.
To be fair to respond.io, the product is strong where it aims to be. It brings WhatsApp, Instagram, Messenger, email and other channels into one inbox, its workflow builder is mature, and the reporting is deeper than most low-cost tools. A team that genuinely uses those features is paying for something real.
Monthly active contacts: the cost that moves
Respond.io prices Growth and Advanced by monthly active contacts, or MACs. Its own pricing guide defines a MAC as a contact who sends or receives a message during the billing month, and says contacts who only receive a broadcast are not counted.
- Growth: starts with 1,000 MACs. Extra contacts cost US$12 per 100 (about S$15), billed at the end of the cycle in blocks of 100.
- Advanced: starts with 1,000 MACs. Extra contacts cost US$15 per 100 (about S$19).
- Starter: respond.io's pricing guide says Starter has unlimited MACs. The pricing page layout is less clear on this, so confirm it with their sales team before relying on it.
The arithmetic is simple. A clinic on Growth that chats with 1,800 people in a month has 800 contacts over the allowance, which is 8 blocks at US$12, or US$96 (about S$123) on top of the plan fee. AI credits work in a similar way: Starter includes 5,000, Growth starts with 10,000, Advanced with 20,000, and extra credits cost US$15 per 1,000 (about S$19).

WhatsApp fees on respond.io: no markup, but separate
Respond.io's pricing page states that WhatsApp fees are not included in any subscription and that Meta charges them based on usage. Its blog says it passes Meta's rates through unchanged, with no markup, and that numbers provisioned through respond.io draw from a prepaid WhatsApp balance that you top up on the platform. The same blog says the card processing fee on those top-ups has been waived from 1 October 2026 until further notice. The fee that applied before the waiver is not listed publicly.
So the WhatsApp side of the bill is the same Meta rate card whichever provider you choose. For messages delivered to Singapore numbers, Meta's rates from October 2026 are about:

Worked example: 3 agents, 1 number, 2,000 marketing messages
Take a Singapore retailer with 3 agents and 1 WhatsApp number that sends 2,000 marketing messages to Singapore recipients in a month. Because broadcasts are listed from Growth upward, the respond.io column uses Growth. Three agents fit inside the 10 included users, and we assume the business stays within the 1,000 MAC allowance.
| Line item | Respond.io Growth (monthly billing) | Respond.io Growth (yearly billing) | RichAutomate Pro |
|---|---|---|---|
| Plan fee | S$254.72 (US$199) | S$203.52 (US$159) | S$19.00 (US$15), credited in full to your wallet |
| Agents | 3 of 10 included | 3 of 10 included | 3 of up to 5 included |
| Meta fees: 2,000 marketing messages at S$0.0937 | S$187.40 | S$187.40 | S$187.40, billed by Meta to your own card |
| Platform usage fees | None listed | None listed | At most S$15.40, paid from the S$19 credit |
| Contact overage | S$0 within 1,000 MACs | S$0 within 1,000 MACs | No contact tiers |
| Monthly total | S$442.12 | S$390.92 | S$206.40 |
The RichAutomate usage line is 2,000 messages at S$0.0026 (S$5.20) plus up to 2,000 conversation windows at S$0.0051 (S$10.20), which is S$15.40 at most. That comes out of the S$19 plan credit, so it is not an extra charge. The Meta line is identical in all three columns, because neither provider marks it up.
Two caveats keep this comparison honest. First, if 500 of those recipients reply and push the respond.io account to 1,500 active contacts, Growth adds 5 blocks at US$12, which is US$60 (about S$77). Second, the yearly price requires US$1,908 (about S$2,442) upfront. All totals exclude GST.
How RichAutomate prices the same job
RichAutomate bills in US dollars outside India. There are three plans:
- Starter: US$9 a month (about S$12), 2 team members
- Pro: US$15 a month (about S$19), up to 5 team members
- White-label: US$19 a month (about S$24), everything in Pro plus up to 10 client accounts
Every plan fee is credited in full to your wallet, so it is spent on usage and not charged on top of it. Our own fees are S$0.0026 per message (US$0.002) plus S$0.0051 for each 24-hour conversation window opened, drawn from that credit. Meta bills its message fees directly to your own card in Meta Business Manager at Meta's rate, with zero markup from us. There is no setup fee, there is a free trial, and there is no lock-in. The full plan list is on our WhatsApp Business API pricing page.
The trade-off is scope. RichAutomate is built around WhatsApp: shared inbox, broadcasts, templates, chatbot flows and an API. If you need Instagram, email and web chat in one inbox, respond.io covers more ground.
Which one fits a Singapore business?
Respond.io suits you if you run several channels at once, have 5 to 10 agents who will use the workflow builder and AI Agents daily, and can keep active contacts near the included 1,000 or accept the overage. At that level the US$199 to US$349 plan fee buys a lot of software.
A lower-cost WhatsApp API plan suits you if WhatsApp is your main channel, your team is 5 people or fewer, and most of your spend is message fees. In the worked example above, the platform fee is the whole difference between S$206.40 and S$442.12.

The short answer
Budget about S$255 a month for respond.io Growth on monthly billing, or about S$204 a month if you pay a year upfront, then add Meta's message fees and any contact overage. Starter is cheaper at about S$127, but broadcasts are not listed on it. Check respond.io's pricing page before you sign, because plans and limits change.
