Why CARIO
Everything you need to be read.
From the first welcome email to your biggest campaign of the year, CARIO keeps your messages looking good, landing in the inbox and easy to measure.
Inbox, not spam
We set up your domain properly and watch your reputation around the clock, so mailbox providers trust you.
AI that helps you write
Get a first draft, a second subject line to test and tips that keep you out of the spam folder.
Results you can trust
See delivered, opened and clicked side by side — and which subject line won your split test.
Respectful by design
One-click unsubscribe, automatic bounce cleaning and GDPR-friendly contact lists keep your sender name spotless.
Your brand, everywhere
Every email comes from your own domain with your logo — never from a shared address.
Made for real businesses
Shops, studios, SaaS teams and agencies use CARIO for receipts, sign-in emails, reminders and newsletters. Simple for marketers, powerful for developers.
Honest numbers. Always.
Many tools count an email as “delivered” the moment it leaves. We only call it delivered when the receiving inbox confirms it.
On its way
Your email has left and the receiving server accepted it.
Delivered
The recipient's mailbox confirmed it arrived. Only then do we say so.
Bounced or reported
We remove the address automatically and warn you before it can hurt your reputation.
Pricing
Simple pricing that grows with you.

Do I need technical skills?+
No. Campaigns, contacts and reports work in the browser. You'll add three records to your domain once — we show exactly what to copy, and most people are done in ten minutes.
Will my emails land in spam?+
We set up your domain authentication (DKIM, SPF, DMARC), clean bounces automatically and watch complaint rates 24/7. Good content and a permission-based list do the rest.
Can I send newsletters and receipts from the same account?+
Yes. Send campaigns to your audiences and everyday emails like order confirmations or password resets from your app — all with one dashboard.
What does it cost?+
Free for up to 1,000 emails a month. Paid plans start at €45 a month, and you can cancel any time.
Where are my emails sent from?+
Your emails are sent through Amazon's EU region in Stockholm, and your contacts live in your own private workspace that no other customer can ever see.
