Mailchimp vs ConvertKit (Kit): Which is Better in 2026?

The short answer

Newsletter or course-first brand? Kit. Default.

Shopify-led D2C with pretty campaigns and “we need something everyone has heard of”? Mailchimp. I’m not being cute; that’s the fork we kept seeing after six months of running both in parallel (different brands, same accountant headaches).

Where Mailchimp actually wins

The editor is the product, really. Drag a block, panic less. When your designer is on Diwali leave and you still have a Republic Day drop to prepone, that matters more than any “creator philosophy” slide deck (your performance marketing lead will still complain about margins, obviously).

• Shopify receipts + promos: Abandoned cart and basic e-commerce rails are where Mailchimp still feels native; Klaviyo is deeper, but Mailchimp beats Kit for-store use cases.
• Template library: If the founder insists each mail “looks like a banner ad from 2019,” Mailchimp’s template muscle wins; Kit will look fine and boring on purpose.
• Hiring freelancers: Say “Mailchimp” in a Mumbai WhatsApp group. Half the interns nod. Say “Kit.” Someone Googles.
• Landing pages in the same login: One fewer SaaS invoice until you outgrow what their page builder can do.

Counter-example: You sell a ₹4,999 Notion template pack and want tag-based drips tied to which upsell someone clicked. Mailchimp can glue that. Kit is already holding the glue in its teeth.

Where ConvertKit (Kit) actually wins

Simplicity is strategy here. Tags instead of five overlapping lists named FINAL_v3_REALLY. Automations that don’t feel like you’re building a tax audit workflow.

• Paid newsletters + digital SKUs: Selling the PDF, the cohort, the “office hours” tier — without bolting WooCommerce drama on top — is where Kit paid for itself for us; Mailchimp is email-with-store-features, not store-with-email-brain.
• Creator sequences: Visual builder + “if they clicked link A, not B” logic stays readable at 11 p.m., which is when Indian founders actually debug flows (IST after US tool office hours).
• Deliverability reputation: Anecdotal but consistent across four founders we asked — fewer “why is Gmail Promotions eating my launch” threads when lists were warm and content was editorial.
• Free tier headroom: 10,000 subscribers free sounds insane until you notice automations are paywalled — still useful for a pre-PMF newsletter hoarding signups from LinkedIn threads about RBI’s recurring payments chatter.

Counter-example: You’re running Diwali SKU floods with 14 segments by RTO pincode and want revenue dashboards that scare your CFO. Kit’s reporting will feel thin; you’ll swear and export CSVs.

Pricing, in INR, no spin

Both bill in [USD]. Your bank will remind you politely with ~2–2.5% forex spread on cards, sometimes worse on corporate cards; budget that like a tiny recurring MDR you can’t negotiate away.

Rough spot math (₹83/$, rounded; check live rates before you commit):

Scenario (so the spreadsheet crowd stops DMing): Suppose you’re at ₹50,00,000 GMV/month with ₹1,200 average order value → ~4,170 orders/month. Assume 40% unique repeat-heavy list growth efficiency and you maintain ~12,000 mailable contacts after hygiene. At that band:

• Mailchimp [USD]: You’re almost certainly off the cheap Essentials headline; Standard/Premium-ish pricing often stacks to roughly $120–$180/mo before add-ons → ~₹9,960–14,940/mo + forex pain + possible SMS/postcard modules ([USD]) that look cheap per send but add reconciliation work.
• Kit [USD]: At 12,000 subscribers, Creator-tier pricing typically sits well above the $25 sticker; budget ~$100–$150/mo class unless you’re on a grandfathered deal → ~₹8,300–12,450/mo + same FX sting.

Hidden costs nobody puts in the landing:

• GST: Mailchimp often routes through Intuit India billing per their India setup — expect 18% GST showing up like an uninvited uncle at a house party. Kit may hit reverse charge mechanics for Indian businesses; your CA will say “depends on entity type” and bill you ₹12,000 for saying it.
• UPI/checkout friction: Neither is “collect ₹99 via UPI inside the app.” You’ll still wire Stripe [USD] or similar for product sales; settlement T+2/T+7 behaviour is real working-capital math, not a footnote.
• Stack creep: Mailchimp’s “replace Unbounce” pitch dies the day you need split URL testing + serious heatmaps. Kit’s commerce saves tools until you need GST invoicing above ₹5 crore turnover talk and e-invoice discipline — then you’re back to Zoho or ClearTax battles.

What we’d actually use each for

If you’re a 12-person D2C team on Shopify with ~₹40L monthly revenue and one retention hire who lives inside discounts: Mailchimp. Not because it’s “better.” Because campaign velocity + template debt + freelancer availability beats Kit’s editorial purity when your Diwali calendar has 47 sends.

If you’re a solo operator with ₹1.8L MRR from cohort courses and a waitlist that feeds a paid Substack-style letter: Kit. Sell the template bundle, tag the buyers, run the post-purchase sequence without inventing a database degree.

If you’re a Bengaluru B2B SaaS with ICP in India and sales-assisted trials: Probably neither as your endgame — but for newsletter + webinar nurture only, Kit’s tagging matches how your SDRs actually think; Mailchimp wins if marketing is hiring an agency that only knows monkey branding.

Indian fit (GST, UPI, IST, support)

Mailchimp gives 24×7 chat on paid plans, which matters when your deploy is at 1 a.m. IST and something breaks. Kit trends US-hours-ish for deep support; fine if you’re async; annoying if your list is actively Indian and your launch is colliding with a long weekend.

INR on invoice? No and no. Budget forex + FEMA-compliant cards; some startups route via virtual USD from Neobanks — your finance team can fight that battle.

UPI for your buyers? Not native. You’ll still lean on Razorpay/Cashfree for India checkout and push emails from whichever tool.

GST templates for transactional mail: Don’t fantasise. These are marketing ESPs, not Clear GST simulators; compliance for e-invoicing thresholds stays in your billing stack.

Migration: what’ll bite you

Mailchimp → Kit: You’ll cry about list vs tag semantics. Unsubscribes and cold segments need a ruthless hygiene pass — Kit hates paying for philosophical dead weight as much as you do. Landing domains and form embeds must be rebuilt; hidden JS on WordPress breaks in exciting ways. Re-map Shopify tags if you were using Mailchimp’s deep integration; webhooks won’t magically rename themselves.

Kit → Mailchimp: Visual automation parity is the lie you tell yourself; you’ll simplify flows or lose branching. Digital products hosted on Kit need a new home — Gumroad, Instamojo workflows, or your own LMS — so expect a week of URL redirects and angry early buyers. Creator Network–style growth loops don’t port; you’ll feel traffic blips.

Both directions: Expect duplicate sends if DNS (SPF/DKIM) isn’t re-warmed conservatively. Export formats are “fine,” not loving; schedule a Saturday where you andCSV become best friends.

What we’d pick

We’d default Kit for our own content-led bets where the product is pixels + PDFs + cohort seats, and Mailchimp when the org’s bottleneck is “make tonight’s mail look acceptable without opening Figma.”

If you can only pay one [USD] bill and your list is India-heavy but your revenue is still mostly cards processed abroad, which pain do you want on your calendar — GST lines from Intuit India or Kit’s lighter reporting — and is your next 90 days anchored on SKUs or subscriptions?

Things people actually ask

“Is Kit really cheaper if I do ₹2 cr/yr?”
Not automatically. Both scale on subscriber/contact counts, not your revenue glory. ₹2 cr with 3,000 VIP buyers can be cheap; ₹2 cr with 80,000 bargain hunters can be expensive. Model headcount of mailable people, not GMV flex.

“Mailchimp Essentials says $13 — why am I seeing $94?”
Because 500 contacts marketing is a honeytrap. Your Diwali list already breached that in 2019. The calculator jumps in [USD]; multiply by ₹83 and swear.

“Do unsubscribes still burn money on Mailchimp?”
Plan-dependent historically; people still rant about unsubscribed-but-stored.contact billing weirdness. Export, archive, fight your past self.

“Can I run UPI collection inside Kit’s checkout?”
No fairy tales. You’ll integrate Indian PSPs around it or stay on Stripe’s India rails and accept the settlement cycle as working capital cost.

“Will Intuit India GST break my runway model?”
It’s predictable 18% if that’s how your invoice routes — bake it like a subscription line item, not a surprise in FY closing week.

“We need serious Diwali segmentation by SKU — who wins?”
Mailchimp if your life is Shopify SKUs and promo codes; Kit if your life is content tags and “clicked pricing page vs syllabus.”

“Reverse charge on Kit — is my CA going to disown me?”
Only if you hide exports. Treat overseas SaaS like adult documentation: invoices PDF’d, GL codes clean, GSTR stories boring on purpose.

“Can we migrate this weekend?”
Technically yes. Emotionally you’ll discover three Zapier zaps nobody documented. Budget Monday for apologising in #growth.

“Which one plays nicer with RBI’s recurring-token anxiety?”
Your payment gateway carries that burden; ESP is Broadcast Raj, not NPCI warrior.
