Mailchimp vs Brevo (formerly Sendinblue): Which is Better in 2026?

The short answer

Messy list? Bulk sends now and then? You care about ₹ more than looking Fortune-500? Take Brevo. Mailchimp wins when design velocity is the bottleneck—when you’re already paying freelancers who live in that UI. Not when you’re squeezing per-send cost or pushing real transactional volume. No spin. That’s what we’ve seen for most SMBs here.

Where Mailchimp actually wins

Drag-and-drop that behaves. Templates your content intern can finish before midnight IST. Journeys are there. The win is polish—fewer “why is this greyed out?” headaches than you get in cheaper all-in-ones. Pricing hurts as you grow (we’ll cover that). Daily use can still be worth it if your team isn’t technical and barely has time to breathe.

• Monthly newsletter plus two or three promo blasts; landing pages without cracking Webflow open again.
• Agency quotes lower because “everyone knows Mailchimp”—meaning fewer billed discovery hours.
• Revenue attribution that’s board-passable without standing up a warehouse.
• US-adjacent SKUs (postcards, SMS) where MC’s roadmap matches who you sell to—India often shrugs at that.

Where it bites: 80,000 contacts in the CRM, you only mail 6,000 twice a month—that Indian “we imported a 2017 PDF once” database. You still pay like you’re hitting the whole file. Audience size drives the bill, not discipline.

Where Brevo (formerly Sendinblue) actually wins

Unlimited contacts, you pay for sends. That’s the cheat for Indian lists—CRM dumps, ancient leads, partner CSVs. Same login for transactional SMTP/API and marketing, instead of “we’ll move to SES later” (you won’t).

• WhatsApp, SMS, email in one place—the ops head wants “one dashboard” before they sign off.
• ₹50L–₹2 cr a year and you still run like a startup: you’ll swallow rough UI if the post-GST, post-forex invoice looks human.
• Your dev wants webhooks that actually work for receipts, resets, “order shipped”—without Mailchimp’s transactional awkwardness at volume.

The loser moment: brand team demands Apple-clean. Brevo’s noise gets old in twenty minutes. Fair.

Pricing, in INR, no spin

Both quote in [USD]; the bank tags 2.5%–3.5% on the card, GST on top depending how the India entity bills—so “$9” isn’t a flat ₹750. Budget ₹780–₹850 after slippage, pre-GST.

Back-of-envelope (Indian D2C, Shopify):

₹50,00,000 GMV a month, AOV about ₹1,200—ballpark 4,167 paid orders. Triggers: confirm + ship + one marketing ping—say three operational touches per buyer (~12,500 transactional/month). Four campaigns to a warm 35,000 list → 1,40,000 marketing sends. Total ~1,52,500/month.

• Brevo: you buy send budget, not a fight with a contact meter. Starter can pinch; you jump to Business [USD] or fight daily caps. Watch SMS/WhatsApp per-message, CRM seats you “just tried,” and the mid-month upgrade when a sale day collides with the limit.
• Mailchimp: 35,000 people on file—even half cold—escalates you past toy tiers fast. Essentials/Standard climbs on contacts, not on who you actually mail. Sneaky costs: features walking off free over time, paid support timing on lower tiers, integration rework.

People forget: your ₹62,00,000 GMV month might already be bleeding ₹1,00,000–₹1,50,000+ on MDR, failed retries, reconciliation—email pennies vs checkout noise is fake precision. Email is recurring; MDR screams louder; the CFO still asks why SaaS never stops climbing.

Forex matters. If treasury is twitchy after RBI on recurring cards and tokenisation, anything [USD] is a policy talk, not a checkbox.

What we’d actually use each for

Twelve people on Shopify, ₹40,00,000 MRR sounds great until you chart blended frequency—then Brevo’s usually grown-up: one API for transactional, promos, WhatsApp tests, without tripling audience logic.

Services shop, ~2,000 high-intent subscribers, one sharp monthly memo, rotating freelancers—Mailchimp’s good boring: forms, templates, landing pages, fewer “where’s my automation” tickets.

SaaS with serious product mail (resets, trial pings, invoices) plus a fat dormant list from Excel—Brevo’s “contacts won’t eat you” model fits; Mailchimp taxes the mess.

Indian fit (GST, UPI, IST, support)

GST lands via India billing entities (both handle India in practice; neither is “Indian pricing” in the sense of INR on the pricing page—still [USD] SMB posture). UPI to settle the subscription? Card and normal invoicing. Don’t wait on UPI from the ESP.

IST: campaign stuck on “Sending,” it’s Friday night before billing closes—Mailchimp gives 24×7 chat on paid; Brevo is email/chat that partly overlaps IST until it doesn’t. This isn’t your CA on e-invoicing thresholds; it’s SaaS support.

Migration: what’ll bite you

Mailchimp → Brevo: tags/groups don’t map 1:1 to lists/folders/attributes—plan a spreadsheet weekend. Automation recipes don’t travel—rebuild flows, re-check triggers, re-run Shopify journeys (order webhooks vs old MC events). Double opt-in and consent fields: “we were GDPR-cool in 2019” meets “why did half bounce.”

Brevo → Mailchimp: “unlimited contacts” vanishes; list hygiene suddenly matters. Transactional SMTP ties need a new home or MC’s transactional story (not the same for many). SMS/WhatsApp may shrink unless you bolt on elsewhere.

Either way: Shopify/Woo plugins aren’t drop-in—reinstall, re-authorise, remap attribution. Tracking and UTMs wobble for a week; someone will blame deliverability when it’s analytics. Prepaid annual [USD]? Price the pain before you switch mid-cycle.

What we’d pick

Typical Indian SMB we know—dirty lists, GST invoices, devs who want SMTP, marketing who want pretty—Brevo. Mailchimp stays when the operator isn’t technical and the brand pays for smoother UI.

Forced pick today across our own portfolio with mixed transactional + marketing: Brevo—unless hiring assumed Mailchimp literacy from day one. Invoice shocks, or how fast an intern ships a Diwali mailer without paging you—what are you actually optimising for?

Things people actually ask

“Bhai is Brevo really cheaper if I’m doing ₹2 cr/year revenue?”
Mostly yes on per-send if the list is huge but sends stay sane—Mailchimp’s contact ladder in [USD] ramps fast. Blast daily and Brevo caps can sting. Model sends, not bragging rights on subscriber count.

“Mailchimp free tier—still worth it in 2026?”
Fine to prove a newsletter exists (500 contacts / low volume). Watch free features shrink; last year’s “enough” turns into paid scaffolding. Treat free as a demo strip.

“Do I need to redo my GST invoice template if I switch tools?”
The ESP isn’t your GST ERP. Pain is whether order emails, SMS links, and merge fields still match finance after e-invoicing rules—not where these tools shine.

“UPI Lite energy: does either integrate cleanly?”
Wrong layer—payments stay in Razorpay/Paytm/etc. You want webhooks into journeys, not UPI inside the mail UI.

“Deliverability ‘guarantee’?”
No one serious promises inbox. Both work with hygiene. Brevo catches flak sometimes; Mailchimp rides brand, bad lists still sink you. Warm domains; SPF/DKIM. Boring wins.

“Transactional + marketing in one login—trap or feature?”
Feature when you’re small and fewer vendors help; trap when you want best-of-breed at scale and engineers despise bundles.

“Shopify: which app hurts less?”
Both ship something real; migration hurts when audiences duplicate and attribution doubles for a week—freeze before Diwali when everyone “tests” email at once.

“Support at 11pm IST—who answers?”
Mailchimp paid chat wins on raw availability; Brevo can work until it doesn’t for a timed blast—if revenue rides on that send, what’s your backup when neither ticket queue owes you a SLA you can bank on?
