Aslio vs Brevo
Brevo already got the billing right. This is about the rest.
Most comparisons on this site turn on pricing model. Not this one — Brevo bills by emails sent with unlimited contacts, exactly as we do. The differences that remain are unit price, and whether you want a platform or an endpoint.
In short
Brevo and Aslio use the same billing model — unlimited contacts, priced by emails sent — so the honest difference is unit price and product shape. Brevo Starter is about $65 for 100,000 emails a month as at 30 August 2026; the same volume on Aslio is roughly $21 at ₹0.02 a message. Brevo gives you a full marketing platform with a campaign builder; Aslio gives you a REST API.

What you get
What Aslio gives you instead
Fewer features, stronger guarantees on the one thing it does.
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 Brevo is the right choice
- You want SMS or WhatsApp working this month. Brevo has both live. Ours are built but not shipping — do not choose us on a promise.
- You want a campaign builder, forms, landing pages or a CRM. Brevo bundles all of it; Aslio is one endpoint.
- Your marketing team, not your engineers, owns sending.
- You are in the EU and want an EU-headquartered vendor with the compliance posture that comes with it.
- 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.
- 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 Brevo?
Per email, substantially: about $21 against $65 for 100,000 sends a month as at 30 August 2026. But note that Brevo already bills per send with unlimited contacts, so this is a unit-price difference, not a model difference — and Brevo's price includes a campaign builder, landing pages, SMS and a CRM that Aslio does not have.
Do Brevo and Aslio charge for contacts?
Neither does. Brevo gives unlimited contacts on every plan including free, and Aslio has no contact concept at all — you send to addresses. If a vendor is charging you to store a list, that is Mailchimp's model, not Brevo's or ours.
Does Aslio do SMS and WhatsApp like Brevo?
Not yet. Both are built and neither is shipping — SMS is waiting on Indian DLT registration and WhatsApp on Meta verification. Brevo has both live today. If multi-channel matters now, that is a real reason to choose Brevo.
What does Aslio do better?
Two specific things, both unglamorous: idempotent retries enforced by a unique index rather than left to you, and automatic wallet refunds when a charged message permanently fails. Plus a flat rate with no volume bands to cross.
Can I run both?
Yes, and for a cautious move it is what we would suggest — keep campaigns in Brevo, move your application's transactional mail to Aslio, and compare the delivery events before shifting anything else.
Same model. A tenth of the rate.
Top up a wallet and send. No monthly platform fee, no seat charge, no minimum commitment — a hundred test emails costs about one rupee.
