Sendinblue vs MailerLite for Local Small E-shops

Free Tier Math: Subscriber Caps and Daily Sends

MailerLite’s free plan gives you 1,000 subscribers and 12,000 monthly email sends — no daily cap. That’s four broadcast newsletters per month to a thousand contacts, which covers a boutique doing RM20k monthly revenue from Instagram traffic. Sendinblue’s free tier caps at 300 emails per day (roughly 9,000 monthly), which punishes you the day you run a payday sale blast to 800 customers — you’ll hit the ceiling by noon and the queue just drops.

The paid floors matter for cash-strapped startups:

– MailerLite: USD 10/month (~RM 47) for 1,000 subscribers, unlimited monthly sends. Cost scales with list size, not volume.

– Sendinblue/Brevo: USD 9/month (~RM 42) for 5,000 monthly emails. Cost scales with volume, not list size.

For a small e-shop sending 2,000 promotional emails a month to a 2,500-address list, MailerLite is RM 47. Sendinblue would be on a higher tier (around 20,000 emails at USD 39, ~RM 182). The math flips only if you need heavy transactional volume.

Automation Triggers for Carts and Replenishment

Local e-shops live on abandoned cart recovery — Klang Valley customers browse on mobile, add to cart, then close the browser to check Shopee. Both tools handle the basic trigger: 60 minutes after checkout abandonment, send a two-email sequence with a 10% off code.

MailerLite’s automation builder is linear but readable — you build a flow as a single vertical line, which is fine for cart recovery and a first-purchase thank-you loop. Sendinblue’s builder supports multi-branch logic: if the customer clicks the WhatsApp link, skip the email sequence and log the action. That’s genuinely useful because Malaysian customers respond faster to WhatsApp pings than email follow-ups — Sendinblue can trigger a WhatsApp message from the same flow. MailerLite has zero WhatsApp or SMS triggers; you’d need Zapier or a third-party workaround.

Another concrete edge: Sendinblue lets you add a replenishment trigger — “bought coffee beans 30 days ago, send a refill prompt.” MailerLite requires you to manually segment purchase history from Shopify. Both integrate with Shopify and WooCommerce, but Sendinblue pulls order data deeper into the flow builder without custom code.

Transactional SMTP: Where Sendinblue Separates

This is the real operational split. Your e-shop sends order confirmations, FPX payment success notifications, and shipping updates from the same domain. MailerLite has no transactional email API — you cannot send a WooCommerce receipt through their SMTP endpoint. You’d pair MailerLite with a separate transactional service like Postmark or Amazon SES, adding RM 30–50/month in cost and a second dashboard to monitor.

Sendinblue/Brevo includes a transactional SMTP relay on all plans. Free tier gets 300 transactional emails per day — enough for a store doing 20–30 WooCommerce orders daily (each order typically triggers 2–3 emails: receipt, payment confirmation, shipping). The sender reputation is shared but reliable; for Malaysian domains, Gmail and Hotmail deliverability holds up if you authenticate SPF and DKIM on your .com.my domain.

One local warning: if you’ve been blasting 5,000 emails from a new domain with a rented database (common mistake for e-shops buying lists from third parties in Kuala Lumpur), both platforms will flag you. MailerLite enforces a stricter opt-in policy — it will suspend accounts on high spam complaints faster. Sendinblue gives you a warning window but throttles your sends. Clean your list before importing either way.

Shopify and WooCommerce Integration Reality Check

For a WooCommerce store hosted on a RM 60/month shared server in Singapore, both plugins install in under ten minutes. The difference is in sync behavior.

– MailerLite: Syncs subscribers from a custom “newsletter” checkbox at checkout. It respects GDPR and PDPA compliance (Malaysia’s Personal Data Protection Act), which is legally relevant if you’re collecting email at checkout. Historical orders are imported, but the automation builder only sees new events after the connection is activated — past abandoned carts won’t retroactively trigger.

– Sendinblue/Brevo: Pulls in full order history and syncs product catalog metadata, which enables those replenishment triggers. You also get a Shopify checkout form that appends buyers to transactional lists by default — MailerLite doesn’t do this without setting up a second list and a webhook.

For stores on Shopify, both work natively. However, MailerLite’s native landing page builder is superior — 40+ templates that load fast on Malaysian 4G connections. Sendinblue’s landing page editor feels dated, and if your paid ads on Meta send traffic to those pages, you’ll lose conversions to slower load times.

Pick Based on Your KL Store’s Email Volume

Run this decision against your actual weekly data, not feature marketing:

Choose MailerLite if your e-shop is promotional-first — weekly newsletters, product drops, and simple cart flows. You stay on the free plan longer, the editor is faster to build on, and the interface is genuinely easier for a non-technical founder managing marketing from a phone in a Bangsar café.

Choose Sendinblue/Brevo if your e-shop is operational-first — transactional receipts matter, you want WhatsApp follow-up for order status, and you plan to run replenishment campaigns for consumables. You’re paying for the SMTP relay and the order-data depth, not the newsletter editor.

One concrete metric to decide today: pull your last 30 days of Shopify order counts. If you send more than three emails per order (receipt, fulfillment, review request), go Sendinblue. If your email list is bigger than 2,000 and growing via Meta ads, go MailerLite and save RM 100+ monthly.
