Professional mailboxes on your domain — and a transactional API to send password resets, notifications, and receipts — unified in one dashboard. The only backend platform with real email hosting built in.
Mailboxes and transactional sending are separate products with separate vendors, separate APIs, separate billing, and separate deliverability configurations. Everyone needs both. Nobody offers both.
SPF, DKIM, and DMARC records need to be configured correctly for emails to reach inboxes. Get any one of them wrong and your emails land in spam — or get silently dropped.
Most email APIs charge per-email at rates that become significant at scale. A high-traffic app sending welcome emails, receipts, and notifications can accumulate thousands in email costs alone.
Send password resets, receipts, notifications, and campaigns via API. Reliable delivery, real analytics, and full control over your templates.
When you add your domain, we guide you through DNS record setup and auto-publish every record needed for proper email authentication. You go from zero to full deliverability in under 10 minutes.
Authorizes our servers to send email on behalf of your domain. Auto-published when you add your domain.
Cryptographically signs every outgoing email. Proves authenticity to receiving servers and protects against spoofing.
Tells receiving servers what to do with emails that fail SPF or DKIM. Protects your domain reputation from abuse.
Enter your domain in the dashboard. We generate the DNS records you need to add — SPF, DKIM, DMARC, and MX records.
Add the DNS records to your registrar. We verify them automatically and activate your domain within minutes.
Create as many mailboxes as you need. Configure them in any IMAP client — or use our webmail interface immediately.
Use your API key to send transactional emails from the same domain. Your app sends from the same address as your team's mailboxes.
We're the only BaaS that includes real email hosting. Every other platform makes you integrate a third-party email provider — a separate bill, separate API key, separate dashboard. We include it.
2 mailboxes + 1,000 transactional emails/month. No credit card required.
A local business owner wants professional@theirbusiness.com email without paying for Google Workspace per seat. ONVIX gives them mailboxes on their domain, a webmail interface, and the ability to send order confirmations via API — all on the free tier initially.
A SaaS startup sends welcome emails, password resets, and weekly reports from noreply@theirapp.com via API, while their team uses support@theirapp.com as a real mailbox. Same domain, same dashboard, one platform.
An e-commerce store sends 50,000 order confirmation emails per month. With per-email transactional APIs, that's $500+/month in email costs alone. ONVIX's flat pricing makes high-volume transactional email predictable and affordable.
All five products include a generous free tier. No credit card required. Pricing announced at launch — early waitlist members lock in founding rates.
