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.
| MailKaka | MailerSend | |
|---|---|---|
| Sending region | Mumbai, India (AWS ap-south-1) | No India region -- EU-based infrastructure |
| Free tier | 3,000 emails/month, no fixed daily cap | 500 emails/month |
| Entry paid plan | ₹899/month (25,000 emails) | $5.60/month (~₹470+, 5,000 emails) |
| Billing currency | INR via Razorpay, GST invoicing | USD (also shows EUR/GBP, invoiced in USD) |
| Replies | Land in a real shared team mailbox | Outbound-focused -- no built-in reply mailbox |
| Extra channels | Email only, by design | Adds WhatsApp and SMS as paid add-ons |

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.
