WhatsApp, Instagram and email automation for businesses in Singapore

Meta moved Singapore out of its Rest of Asia Pacific group on 1 July 2026, so messages to +65 numbers now have their own rate line, and Meta publishes a Singapore dollar rate card. That changes Meta's price per message, not Slide's currency: Slide bills a Singapore workspace in US dollars and takes WhatsApp charges from its prepaid wallet.

Marketing is where Singapore differs most. The Do Not Call provisions apply to marketing messages sent to Singapore numbers by voice, SMS or data applications such as WhatsApp. Unless you hold clear and unambiguous consent in a form you can produce, check each number against the DNC registry within the 21 days before you send. The registry check happens outside Slide; inside Slide, keep checked or consented numbers in their own tag or segment and send marketing templates only to that segment.

Singapore is also one of the two markets, with India, where WhatsApp address request messages work, which helps when a delivery address is needed inside the chat. For the full picture, read WhatsApp automation in Singapore and the sales conversion workflow, which builds DNC checks into lead follow-up.

The DNC rules attach to Singapore telephone numbers, so they do not govern a reply to an Instagram account. Instagram automation in Slide runs on Meta's global rules instead: replies within 24 hours of the person's last message, one private reply per comment within 7 days, no broadcast DMs and nothing after the window closes.

Inside those rules Slide replies to comments with keyword rules, answers story replies and live comments, asks quick-reply questions, captures email addresses into contacts, and can pass the conversation to an AI agent or a teammate. Anything you collect is personal data under the PDPA, which generally needs consent and a notified purpose, so say what an email address will be used for when the DM asks for it.

The Spam Control Act has covered instant messaging accounts since 2020, and it is aimed at unsolicited commercial messages sent in bulk. Slide sends Instagram messages only as replies to people who wrote or commented first; whether a particular reply falls under the Act is a question for your adviser.

The Spam Control Act sets the email rules. It covers unsolicited commercial messages sent in bulk, meaning more than 100 in 24 hours, 1,000 in 30 days or 10,000 in a year, and requires the "<ADV>" label and an unsubscribe facility on that email. Instant messages are in scope as well but are exempt from the label.

Slide's email campaigns carry one-click unsubscribe and suppress hard bounces and complaints, and sequences add an unsubscribe line by default. Add the "<ADV>" label yourself when you write a campaign that needs it. The automation "send email" step adds no unsubscribe and ignores the unsubscribe list, so keep marketing out of it. The setup, including the PDPA, is on email automation in Singapore.

Slide bills a workspace created with a Singapore number in US dollars; there is no Singapore dollar billing. Plans and current prices are on the pricing page, and paid plans start with a 14-day trial. Confirm the payment method, for the plan and for wallet top-ups, with the Slide team before you subscribe.

WhatsApp messages are charged by Meta per message, by category, at the Singapore rate for +65 numbers, and Slide takes the charge from your prepaid wallet; when the wallet is empty, sends stop. Since 1 October 2026 service replies are charged too, once a business number has used its 1,000 free service messages for the month. Conversations opened from a Click-to-WhatsApp ad stay free for 72 hours when you reply within 24 hours.

The exact per-message price for your account is shown in the wallet. Email sends use the email credits in your plan, and a sequence pauses when they run out.
