High performance email deliverability platform for serious senders who care about their critical emails landing in the inbox.
Originally built in-house at
Bento
to monitor billions of emails, Tatami gives high-volume senders real-time deliverability intelligence, reputation tracking, and actionable alerts in one place. Designed for ESPs, multi-tenant SaaS, and people who send a lot of emails where delivery is critical.
We support all major ESPs and MTAs.

Tatami is now AI-first
NEWAsk Tatami how the night went. Ask who is in Spamhaus. Ask how to fix a bounce.
how is delivery today
Pretty quiet overnight.
About 1.89M went out, 98% landed, bounce sat at 2.05%. The ~67k deferrals look like backlog and concurrency, not a fire.
Gmail, Outlook, and Yahoo all look fine. Yahoo and Outlook deferrals are just the usual throttle noise.
Nothing to chase. Most of the bounces are mailbox-full. Two Microsoft “admin banned” rejects, those are recipient-side, not your IPs. No reputation or auth spikes.
Simple, transparent pricing
$10 per million emails. First 100 IPs are free. Everything else is included.
Billed at $10 per million. 3 million minimum.
First 100 IPs are free. $1 each after that.
Tenants, providers, users, and domains are unlimited.
