Aslio vs Mailchimp
Mailchimp charges for the list. We charge for the sending.
Mailchimp prices by contacts stored, so a list you grew and rarely mail costs the same as one you mail daily. If your sending is occasional and your list is large, that is the whole problem — and it is the one thing this fixes.
In short
Mailchimp is priced by contacts stored — about $75 a month for 5,000 contacts on Essentials as at 30 August 2026, charged whether or not you send. Aslio is priced per message at ₹0.02 each, roughly $0.21 per 1,000, so mailing those 5,000 contacts weekly costs about $4 a month. Mailchimp is a complete marketing platform; Aslio is an API, with campaign tooling in Aslio Flow.

Side by side
Mailchimp figures are their published Essentials and Standard rates as at 30 August 2026; check theirs before deciding. Ours are exact.
| Mailchimp | Aslio | |
|---|---|---|
| What you are billed for | Contacts stored | Messages sent |
| 5,000 contacts, no sends | About $75/month (Essentials) | ₹0 — you are billed for nothing |
| 5,000 contacts, mailed weekly | About $75/month | About $4/month |
| Growing the list | Raises the bill immediately | Changes nothing until you mail them |
| Campaign builder and templates | Yes, and it is the product | No — API only; campaigns are in Aslio Flow |
| Landing pages, ads, social | Yes | No |
| Audience segmentation UI | Yes, mature | In Aslio Flow, early access |
| Deliverability tooling | Extensive | Own domain and DKIM, suppression, delivery events |
| Suits | A marketer who wants a whole platform | Someone technical who wants to send |
This comparison is only fair if you would actually use an API. Mailchimp is a far more complete product for a marketer, and if you want to build a campaign in a browser on Tuesday afternoon, buy Mailchimp.
Code
Mailing a list
Up to 1,000 recipients a call, each with their own merge variables, its own charge and its own unsubscribe link.
POST /v1/email/send-batch
{
"from": "Acme <news@acme.com>",
"subject": "Hi {{firstName}}, your invoice is due",
"html": "<p>Hi {{firstName}} — {{plan}}</p>",
"recipients": [
{ "email": "priya@example.com",
"variables": { "firstName": "Priya", "plan": "Pro" } }
]
}
// Up to 1,000 recipients per call. Each gets its own message
// row, its own charge and its own unsubscribe link. Suppressed
// addresses are skipped and reported, never silently dropped.What you get
What sending on Aslio gives you
The infrastructure, without the platform around it.
Idempotency that holds
Send with an Idempotency-Key and retry as often as you like. A duplicate replays the original response instead of sending twice — enforced by a unique index, not a check-then-write race.
Refunded when we fail
If a message is charged and then permanently fails, the wallet is credited back automatically and the key is released so your retry can succeed.
Suppression before billing
Hard bounces and complaints go on your do-not-mail list. Later sends to that address are rejected before you are charged, which protects your sender reputation and ours.
One-click unsubscribe
Marketing sends carry RFC 8058 headers, so Gmail and Yahoo show a native Unsubscribe button — required for bulk senders since 2024.
Delivery pushed to you
Sent, delivered, bounced and complained events arrive on your statusCallbackUrl webhook, on every account from the first message.
Your own sending domain
You verify your domain and sign with your own DKIM, so your reputation stays yours instead of being pooled with every other sender on a shared IP.
Honestly
When Mailchimp is the right choice
- You want to build campaigns in a browser. Mailchimp's editor, templates and audience tools are the product, and we do not have them.
- You need landing pages, ad integrations or a customer journey UI today. Aslio Flow covers some of this and is in early access, not general availability.
- Nobody on the team writes code. Aslio is an API. That is a hard requirement, not a preference.
- We hold no SOC 2 report and no ISO 27001 certification. If your procurement requires one, we will not pass it today and would rather say so now.
- SMS and WhatsApp are still in build. Email is the channel that ships today. Do not pick Aslio this week for a multi-channel launch next week.
- We are a young, small company — Asli One Global was incorporated in February 2026. That is a legitimate thing to weigh for a critical dependency.
FAQ
Frequently asked questions
Is Aslio cheaper than Mailchimp?
On sending, dramatically — but they bill for different things. Mailchimp charges for contacts stored, about $75 a month at 5,000 contacts on Essentials as at 30 August 2026, whether or not you send. Aslio charges ₹0.02 per message, about $0.21 per 1,000, so mailing 5,000 people weekly is roughly $4 a month. What Mailchimp gives you for the difference is a whole marketing platform.
Can Aslio replace Mailchimp?
For sending, yes. For the campaign builder, templates, landing pages and audience UI, no — those live in Aslio Flow, which is in early access and included with Aslio Pro. If your campaigns are generated by your own application, Aslio replaces Mailchimp cleanly. If a person builds them by hand each week, it does not.
Do I pay for contacts I never email?
No. There is no contact charge at all. A list of fifty thousand you mail twice a year costs you the two sends and nothing else.
What about unsubscribes and compliance?
Marketing sends carry RFC 8058 one-click unsubscribe headers, so Gmail and Yahoo show a native Unsubscribe button — required for bulk senders since 2024. Hard bounces and complaints are suppressed automatically and enforced before you are charged again.
How do I move a Mailchimp audience across?
Export the audience as CSV and send through the batch endpoint with merge variables per recipient. There is no import UI — this is an API, and that is the trade.
Stop paying rent on a list.
Top up a wallet and send. No monthly platform fee, no seat charge, no minimum commitment — a hundred test emails costs about one rupee.
