Newsletters that don’t bill you per name
Listmonk is built for big lists and hard sends — SQL segments, campaign analytics, and a transactional API, on hardware that stays tiny. Deploy on StackBlaze with Postgres and HTTPS. Plug in SMTP. Keep the list.

Why teams pick it
High-volume mail without the contact tax
Mailchimp and Brevo charge as the list grows. Listmonk doesn’t. You run the app, store subscribers in your Postgres, and send through the relay you already trust.
Lists that scale past the pricing cliff
Single and double opt-in lists, millions of subscribers, CSV import, and an API that doesn’t throttle you for growing.
Segments written in SQL
Filter on attributes, status, and campaign history with Postgres expressions — the same language your data already speaks.
Campaigns with real analytics
Schedule and send, then watch views, clicks, top links, and bounces on the dashboard — not a vanity open-rate widget.
Templates your way
Drag-and-drop, WYSIWYG, Markdown, or raw HTML — plus Go templating with logic and 100+ functions in subject and body.
Transactional API included
Fire password resets, receipts, and alerts through the same instance. Messengers can fan out to SMS or webhooks when you need them.
Absurdly light under load
Production runs of millions of messages sit in a fraction of a core and tens of MB of RAM. Scale the send, not the SaaS invoice.
The admin you’ll actually live in
Deploy in seconds
One click. Postgres ready. Admin waiting.
Pick the Listmonk template. StackBlaze creates the app and managed Postgres, attaches uploads, and hands you a public hostname for /admin and signup pages.

platform SMTP when the pipeline has mail
- Stack
- Listmonk + PostgreSQL + Email addon
- First login
- Create the Super Admin at /admin on first open
- Sending
- Confirm SMTP in Settings before the first campaign
After you deploy
- 1
Open /admin and create the owner
First boot finishes migrations, then asks for the Super Admin email, username, and password. That account owns the instance.
- 2
Confirm SMTP
If the pipeline has platform mail, the Email addon is already attached — finish the SMTP row under Settings → SMTP before you send. Or point it at SES, Postmark, or your own relay.
- 3
Import the list, then ship a campaign
CSV or API for subscribers. Build a template, pick lists, schedule or send. Analytics light up as opens and clicks land.
On StackBlaze
Wired for sending, not for seat counts
Listmonk and Postgres ship together. The public hostname is admin and public pages. Mail leaves through SMTP you control.
Postgres is the source of truth
Subscribers, campaigns, templates, and analytics live in CloudNativePG. Restart the app — the list is still there.
You pick the relay
Listmonk queues and rate-limits. SES, Postmark, or platform SMTP does delivery. You’re not locked into a vendor’s inbox reputation.
One hostname for admin and signup
The StackBlaze URL serves /admin and public subscription pages. Attach a custom domain when the list should wear your brand.
Scale the blast, not the plan tier
Bump CPU and RAM when a campaign is huge. Postgres scales on its own. There is no “upgrade for 10k more contacts.”
Compare
Listmonk on StackBlaze vs hosted email marketing
| Feature | Listmonk on StackBlaze | Mailchimp / Brevo-style host |
|---|---|---|
| Pricing model | Compute and Postgres. No per-subscriber fee in the app. | Usually priced per contact, per send, or both. |
| Where the list lives | Your StackBlaze instance and attached Postgres. | Vendor-operated multi-tenant infrastructure. |
| Segmentation | SQL expressions over subscriber attributes and campaign history. | Vendor UI segments — powerful until you hit the plan wall. |
| Delivery | Your SMTP (SES, Postmark, platform mail, or anything else). | Bundled sending — convenient, and priced into the seat. |
| When it’s the wrong tool | Skip it if you need visual journey builders and SMS suites out of the box. | Strong when marketers want all-in-one automation more than ownership. |
Listmonk is campaigns, lists, analytics, and a transactional API. It is not a visual drip builder. You bring (or attach) SMTP.
FAQ
Common questions
Open the public URL and go to /admin. First boot runs migrations, then the Super Admin setup form. Create the owner account there — there is no shipped default password.
