All your business email, in one place.

One platform
Three ways to use Ozi. Start with one.
Most businesses start by sending a newsletter or setting up their inboxes. Everything shares the same domain, contacts and reputation, so adding the rest later takes minutes.
Email marketing
Newsletters and campaigns people open.
Write in a visual editor, send to your lists, and see who opened and clicked. Welcome emails and follow-ups send themselves.
Learn moreBusiness email
Real inboxes on your own domain.
Give everyone an address like [email protected]. Read and reply in the browser, with folders, filters, out-of-office and calendars.

An email API, SMTP and AI agents.

Built to land in the inbox
Every email, accounted for.
See where each email got to, and let Ozi handle the things that quietly hurt your sender reputation.
Delivery you can see
Every email shows whether it was sent, delivered, opened and clicked, or exactly why it wasn't.
Bad addresses blocked for you
Addresses that bounce or mark you as spam are blocked automatically, so one bad list doesn't hurt the rest.
Unsubscribe, done properly
One-click unsubscribe in every campaign, and a page where people choose which topics they hear about.
Double opt-in
New subscribers confirm their address before they're added, keeping lists clean from day one.
Signed from your domain
Mail is signed for your domain, and you can show your logo next to it in inboxes that support it.
Reputation at a glance
Your bounce and complaint rates sit against the lines inbox providers watch, with plain advice when one climbs.

Free for up to 3,000 emails a month. After that, $10 a month covers your first $10 of sending, then $0.001 per marketing email. Pay yearly and save 12%. Your contacts are always free.

What is Ozi?
Ozi is one place for your business email. You can send newsletters and campaigns to your contacts, give your team real inboxes on your own domain, and let your website or app send receipts and alerts through an API.
Do I need to be technical to use it?
No. Adding your domain means copying a few records into the site where you bought it, and Ozi checks them for you. After that, campaigns, contacts and inboxes all work from the dashboard. The API is there for when a developer wants it.
Can I send from my own domain?
Yes, and you should. Every email goes out from your domain, like [email protected], signed so that inboxes trust it.
Do you charge for the contacts I store?
No. You pay for the emails you send, not for the size of your lists. Keep every contact you have.
Is there a free plan?
Yes. The free plan is free for as long as you use it, with no card needed. Upgrade when you outgrow it.
