COMPARISON

MailKaka vs MailerSend

MailerSend is a solid dev-first email API with team features baked in. Here's what changes if you're sending to Indian customers specifically -- region, currency, and what happens after someone hits reply.

WHY TEAMS SWITCH

Four things that actually matter.

A larger free tier. MailerSend's free plan is 500 emails/month. MailKaka's free tier is 3,000 emails/month with no fixed daily cap.

No forex, no GST guesswork. MailerSend invoices in USD. MailKaka bills in INR through Razorpay with GST-compliant invoicing.

Data closer to your customers. MailerSend runs on EU-based infrastructure with no published India region. MailKaka sends from AWS SES's Mumbai region.

Replies don't disappear. MailerSend is built for outbound sending -- there's no built-in inbox for customer replies. Every MailKaka domain gets a real shared mailbox by default.

MIGRATING

Switching from MailerSend.

MailKaka's API follows Resend's request shape, not MailerSend's /v1/email format, so this isn't a one-line swap -- you'll change the request body, not just the endpoint. Sender identity, recipient arrays, and HTML/text bodies map directly.

await fetch("https://www.mailkaka.in/api/emails", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${MAILKAKA_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    from: "hello@yourdomain.in",
    to: ["customer@example.com"],
    subject: "Welcome aboard",
    html: "<strong>It just works.</strong>",
  }),
});

FAQ

Does MailKaka offer WhatsApp/SMS like MailerSend?

No -- MailKaka is email and reply-inbox only, by design. If you need WhatsApp or SMS alongside email from one vendor, that's outside MailKaka's current scope.

What happens to emails MailerSend already sent?

Nothing -- this only affects new sends going forward. There's no data to migrate; you're just pointing new API calls at a different host and request format.
