PostShiba's public beta is open. No more invites.
It's the email infrastructure behind Bento. Now you can build on it too.
We're building it for apps that send and receive email for their customers. Think booking confirmations sent from a customer's domain, or replies landing in your support desk.
The useful bits
Each customer gets their own tenant: a separate space for domains, SMTP credentials, inboxes and suppressions. If you need to suspend one tenant, the others keep sending.
Send over SMTP, HTTP inject or the REST API. Receive replies in hosted inboxes and pass them into your app through signed webhooks.
If an email doesn't arrive, check its delivery events and the receiving server's exact response. If you're stuck, open a ticket.
One fixed price per cluster
Pick a cluster that fits your busiest hour and any rolling 24-hour period. One monthly price. No per-email overages or per-domain fees. Compare the plans.
Start with a test email
Create an account, add a payment method, and tell us what you're sending and your daily volume. Your first cluster comes with a 7-day free trial.
Verify a domain and send a test email to a team member. Before sending to external recipients, request approval through the banner in your dashboard. We review every account by hand, and you can keep testing with your team while we review yours.
The production approval guide covers what you can do before approval.
Build something with it
It's still a beta. Tell us what breaks, what feels awkward, and what's missing. We'd like to see what you're building.
