AI picks the optimal send time
Built on the principles email should have had all along.
The substance under the hood — what makes Utobo Mail feel different the moment you start sending.
One contact graph
Transactional events, broadcast engagement, and automation triggers share the same contact record. No CSV juggling between tools.
An AI writer that ships the whole email
Subject, body, CTA, follow-ups. In every surface: broadcast, automation, even quick API templates.
Reach the inbox, not the spam folder
Managed warmup, DMARC/DKIM/SPF guidance, suppression lists, and DNSBL monitoring on every plan.
Delivery logs you can actually read
90 days of every send, open, click, bounce, and complaint — searchable, exportable, webhook-able.
Automations as easy as A, B, C
Trigger, sequence, launch. No flowchart canvas to fight with — describe each email, AI drafts it, you ship.
Built for the whole team
Your engineers ship transactional code. Your marketers ship campaigns. Same dashboard, same contacts, no Zapier in the middle.
From zero to sending in four minutes.
No sales call. No onboarding. No setup fee.

What founders are saying.
Real feedback from real startups.
"We send order receipts, password resets, and merchant announcements from one stack now. Utobo Mail replaced our transactional provider and our newsletter tool — deliverability went up, bill went down."
Raj Sahu
CEO at utobo.com
Using API + Broadcast
"Spinning up campaigns for client stores used to eat our week. The AI writer drafts subject lines and full sequences that actually convert, and the automation flows mean we ship in days, not sprints."
Ryan
Head of Marketing at Botsmate
Using AI Writer + Automation
"Abandoned-cart and post-purchase flows are doing the work of a junior marketer. Revenue-per-email is now a number I actually watch — Utobo Mail attributes it cleanly back to each send."
