One email platform,
from first user to serious scale.
Transactional email, campaigns and sequences in one place — so you are not stitching three tools, three bills and three contact lists together while you are trying to build a company.
Your workspace is ready.
Sign in to start your first project. This is the kind of message your product sends the moment someone joins.
Open your workspaceOne place
An example workspace for Northstar, a fictional startup. Nothing here sends email.
Stop stitching three
email tools together.
Most startups end up running a transactional provider, a campaign tool and an automation platform side by side — three logins, three invoices, and a contact list that never quite agrees with itself.
utobo Email does all three. One workspace, one monthly bill, and one contact list that transactional, campaigns and sequences all read from.
Explore campaignsPricing you can
plan around.
Three tracks, each with a clear starting point. Transactional from $9/mo for 10,000 emails. Promotional from $19/mo for 2,500 contacts, with unlimited campaign sends — you pay for contacts, not sends. All-in-one from $24/mo brings both together.
AI drafting is included on every plan at no extra cost — so writing onboarding, a newsletter or a re-engagement note never costs more.

Built on AWS SES
A proven sending backbone under every message you send.
DKIM and SPF
Authenticate your sending domain in the setup flow to protect your reputation.
Bounces and complaints
Handled automatically, with hard failures added to your suppression list.
Suppression kept current
Addresses that should not be emailed are filtered out for you, so your list stays clean.
Deliverability,
handled for you.
Sending runs on AWS SES. Add your own sending domain, complete DKIM and SPF in the setup flow, and let bounces and complaints be handled and suppressed automatically — without a job of your own.
A successful send means the message was accepted for sending. The recipient's mail system still decides inbox placement.

grows with the company.
Start with the email your product needs, add campaigns when you have something to say, and connect the two as you scale — without changing tools.
Pre-launch
Wire up transactional email for your waitlist, onboarding and password resets. Transactional from $9/mo.
Post-launch
Add campaigns when you have something worth sending. Promotional from $19/mo, with unlimited sends to your contacts.
Scaling
Move to All-in-one and run transactional and marketing on one contact list, from $24/mo.
Bring the
whole team in.
Add your co-founder, your first hire and the contractor helping this month. Role-based access keeps each person to what they need — and keeps sending, contacts and API keys out of the wrong hands.
One workspace the team shares, rather than a password passed around.
See what each plan includesBefore you choose a stack.
Do I really get transactional and marketing in one account?
Yes. Transactional email, campaigns and sequences run in the same workspace, on one contact list and one bill. The All-in-one plan connects transactional and marketing directly; the Transactional and Promotional plans focus on one job each.
How does pricing work as I grow?
Transactional starts at $9/mo for 10,000 emails. Promotional starts at $19/mo for 2,500 contacts with unlimited campaign sends — you pay for contacts, not sends. All-in-one starts at $24/mo. AI is included on every plan.
Is AI really included at no extra cost?
Yes. AI drafting is part of every plan, so you can write onboarding, a newsletter or a re-engagement email without a separate subscription or a per-message fee.
How fast can I send the first email?
Verify a sending domain, create an API key, and send with one POST or an SDK call. Most teams have a test message out in a few minutes. SDKs are available for Node.js, Python, Ruby and Go, with PHP coming soon.
How is deliverability handled?
Sending runs on AWS SES with DKIM and SPF authentication for your domain. Bounces and complaints are handled automatically and added to a suppression list, so your list stays clean without a job of your own. A successful send means the message was accepted for sending, not that it reached an inbox.
Can I add my team?
Yes. Invite your co-founder, your hires and contractors, and give each the role they need. One shared workspace, no shared password.
What if I only need transactional email today?
Start on the Transactional plan for your app mail, and add campaigns later on the same account when you are ready — there is nothing to migrate and no second tool to learn.
One platform for every email your startup sends.
Start with transactional from $9/mo, add campaigns when you are ready, and keep everything on one login and one contact list. AI is included on every plan.
