Business email on your own domain
Mail that looks like your company, not a leftover inbox.
Add a domain, create hello@ and sales@, then work from a calm inbox with search, drafts, and organization tools in one place.

How it works
From domain to inbox in three steps
No mail-server puzzle. Mailkub walks you through the parts that matter.
Connect a domain
Add acme.com or your brand domain. We generate the DNS records and can write them to Cloudflare.
Create addresses
Spin up hello@, sales@, or a personal mailbox. Set quotas and reset passwords when you need to.
Send and receive
A quiet inbox with folders, search, drafts, and attachments — plus an org view for domains and people.
Custom domains
MX, SPF, DKIM, and DMARC instructions for every domain you add.
A calmer inbox
Star, search, draft, and reply without the clutter of a 2004 mail client.
Team addresses
Give each person or role their own mailbox on your domain.
Org tools that stay out of the way
Users, quotas, and mailboxes in one place — only when you need them.
Sign-in you control
Workspace and platform admin stay separate. Turn on authenticator 2FA yourself.
DNS without the guesswork
Copy records, or let Cloudflare apply them so verification is not a scavenger hunt.
