One platform. Three superpowers.
Everything your startup needs to send emails — built into one clean dashboard.
Your transactional email infrastructure. Three lines of code.
Send welcome emails, password resets, order confirmations, and any programmatic email straight from your app. The Averium API is dead simple — if you've used Resend, you already know it. If you haven't, you'll figure it out in 10 minutes.
- Resend-compatible REST API
- 100 req/min per key, 500/min per org
- Full delivery logs + error reporting
// Send a transactional email
const res = await fetch(
"https://api.averium.ai/v1/send",
{
method: "POST",
headers: {
"Authorization": "Bearer av_live_••••••",
"Content-Type": "application/json"
},
body: JSON.stringify({
from: "noreply@yourstartup.com",
to: "user@example.com",
subject: "Welcome to YourApp 👋",
html: welcomeEmailTemplate
})
}
);
// → { "id": "msg_01JX...", "message": "Email sent." }Hey there,
Just a heads up — our 30% off sale ends at midnight tonight. We're not extending it this time, so grab what's been sitting in your cart before it's gone.

What founders are saying.
Real feedback from real startups.
"I was paying $22 for Resend, $35 for Beehiiv, and $50 for Mailchimp. Moved everything to Averium in a weekend. Saved $85/month and honestly the product is better."
Jake M.
Founder at Replo
Switched from Resend + Beehiiv + Mailchimp
"The AI writer is unreal. I described our product launch in one sentence, it wrote a subject line and full email that outperformed every email we wrote manually. Open rate was 47%."
Priya S.
Co-founder at Supermaven
Using Broadcast + Automation
"I'm a developer, so the API was the first thing I tested. Clean, fast, well-documented. I integrated it in 30 minutes and it hasn't had a single failure in 3 months."
