Email infrastructurethat sets itself up.
Connect your DNS provider, authenticate every sending domain in minutes, set up managed mailboxes and send through custom SMTP or dedicated IPs — with deliverability protection on every email.
Reviewed 14-day trials · DNS setup in minutes · Free deliverability audit
From new domain to first reply in five steps.
The infrastructure work that used to take a week — DNS, authentication, mailbox setup, warmup — now runs automatically in the background.
Authenticate every domain in minutes.
Connect your DNS provider once through its API — or pick manual setup. CloudJet writes SPF, DKIM, DMARC, MX and tracking records for every domain, verifies them, and keeps checking.
- API connection to Cloudflare, GoDaddy, Namecheap & more
- SPF, DKIM, DMARC, MX & tracking CNAME
- Daily re-checks that fix drift automatically
Hundreds of mailboxes, ready in minutes.
Create Google Workspace, Microsoft 365 or private SMTP mailboxes in bulk — names, signatures, forwarding and warmup are configured for you.
- Bulk-create from CSV or naming rules
- Google, Microsoft & private SMTP mailboxes
- Warmup and daily caps applied automatically

Custom SMTP, SMTP API and dedicated IPs.
Bring your own SMTP servers or send through ours. Call the REST or SMTP API from your app, and isolate your reputation with dedicated IPs and managed IP pools.
- Custom SMTP with TLS & connection pooling
- REST + SMTP API with real-time webhooks
- Dedicated IPs, pools & automatic IP warmup
Sender protection that never sleeps.
CloudJet watches bounces, complaints and seed placement on every send. When a mailbox, domain or IP shows risk, traffic is paused or rerouted before your reputation takes the hit.
- Auto-pause & health-aware rotation
- Inbox placement tests across providers
- Lead verification blocks bad addresses

No — you bring domains you already own (or register yourself). Each plan sets how many of your domains you can connect and authenticate. DNS automation runs on those connected domains. If you want us to buy and configure domains for you, that’s an optional paid add-on.
