The multi-product email problem
Every option available to indie hackers has the same flaw: it was built for someone else.
You just launched product #4
ProductHunt wants `[email protected]`. Google Workspace charges $7/month per domain — that's $84/year for a product that might fail in 3 months. So you try Cloudflare Email Routing instead. It forwards fine, but when you reply, recipients see "via gmail.com". Not exactly the brand you're building.
$84/year × 10 domains = $840/year on Google Workspace
Your app needs to send password resets
You set up Resend for transactional email. Now you're on two billing dashboards, two DNS setups, two deliverability problems to monitor. The domain your app sends from isn't the same as your inbox domain. Alignment costs overhead you don't have.
Resend Pro: $240/year on top of whatever you pay for email
Self-hosting sounded like a good idea
Mailcow on Hetzner. Took a weekend. Three months later: Gmail spam folder, a failed DKIM rotation, Rspamd tuning you haven't had time to do. You're an indie hacker, not a mail server operator. The deliverability problem is worse than the billing problem.
Hetzner VPS + operational time: more than $0, more than $49
Built for the way indie hackers actually work
Three specific problems, solved together — not as three separate subscriptions.
Unlimited domains, flat price
Add every product domain you launch. No per-domain charges, no per-mailbox fees within your plan's storage limit. One $49/year plan covers all of them — whether you have 3 domains or 30.
Catch-all and unlimited aliases per domain. Auto-configured DKIM, SPF, and DMARC records — one click if you're on Cloudflare DNS.
Google Workspace: $84/year × 10 domains = $840. MailStoa Maker: $49 total.
SMTP relay for your apps
Your app's password resets, signup confirmations, and receipts send through MailStoa. Same credentials, same domain, same bill. No separate Resend or Postmark account for light transactional volume.
Connect via smtp.mailstoa.com:587 (STARTTLS) or :465 (TLS). Standard SMTP — works with Nodemailer, smtplib, ActionMailer, Laravel Mail, and anything else that speaks SMTP.
Resend Pro: $240/year separately. MailStoa: included in your plan.
EU jurisdiction, indie operator
All customer mail stored on Hetzner in Falkenstein, Germany. EU privacy law applies. Operated by one person — me, Khoa, from Nha Trang, Vietnam. Public roadmap, public status page, no surveillance.
StoicSoft has shipped and maintained Server Compass and 1DevTool. MailStoa is the same operational standard — built for the long game, not a venture-backed sprint.
Most email providers: American or Australian jurisdiction. MailStoa: Germany.

* Cloudflare Email Routing is free but forward-only — cannot send replies from your custom domain. Fastmail pricing assumes $60/year per user across 10 domains. MXroute pricing is Studio plan.

Built by someone who uses it
I'm Khoa, a solo developer operating from Nha Trang, Vietnam. I built Server Compass and 1DevTool under StoicSoft — tools I use myself that pay the bills while I build the next thing.
MailStoa came from my own frustration. Running multiple products means managing multiple domains, and nothing on the market handles this the way indie hackers actually work. Google Workspace is priced for companies. MXroute is technically excellent but the UI feels like 2010. Self-hosting sounds appealing until your first Hetzner deliverability problem.
I'm building MailStoa because I want to use it. If I can validate demand with 30 paying founding members in 30 days, I'll commit 6 months to the infrastructure build. If not, I'll refund everyone and move on. That's the deal.
Solo-operated means one decision-maker, one accountability, one person who answers the support email. That's a feature, not a limitation.

Frequently asked questions
Specific answers to real objections. If something's missing, email [email protected].
What is MailStoa?
MailStoa is flat-priced email hosting for indie hackers running multiple SaaS products. You get unlimited custom domains, a built-in SMTP relay for your apps' transactional email, and modern webmail — all for $49/year on the Maker plan.
Who is it for?
Indie hackers and solo founders who manage 2–20 product domains. If you've ever paid Google Workspace per domain, tried Cloudflare Email Routing and hit the forward-only limitation, or spent a weekend configuring Mailcow only to land in spam folders — MailStoa is for you.
How is MailStoa different from MXroute?
MXroute is technically excellent and we respect it. The difference is UX and positioning. MXroute uses DirectAdmin and Roundcube, which work but feel like 2010. MailStoa is building a modern UI, mobile-friendly from day one, with a SMTP relay feature specifically marketed to indie hackers who need app email in the same service as inbox email.
How is MailStoa different from Google Workspace?
Google Workspace charges $7/month per user per domain. For 10 domains, that's $840/year — and that's per user, meaning shared inboxes cost more. MailStoa Maker costs $49/year total for unlimited domains. Google also logs and processes your email for product improvement. MailStoa does not.
How is MailStoa different from Fastmail?
Fastmail is excellent for personal and professional email. It's built for individuals and small teams who mainly use one domain. Multi-domain support in Fastmail is buried in settings and expensive. MailStoa is built specifically for the multi-domain indie hacker use case.
Where is customer mail hosted?
Hetzner data center in Falkenstein, Germany. EU jurisdiction, GDPR applies. No data stored in the US or under US legal jurisdiction. Backups encrypted off-site.
Who runs MailStoa?
One person: Khoa, a developer operating from Nha Trang, Vietnam. StoicSoft also runs Server Compass and 1DevTool. Solo operation means one accountability — when something breaks, one person owns it and fixes it.
What happens if you shut down MailStoa?
If the project is killed after the pre-sale validation period, all founding members are refunded within 48 hours and a public retrospective is published. Once V1 launches, a documented continuity plan exists: customer data export in standard format, at least 90 days notice, and a partner operator identified for handoff if needed.
What is the founding member offer exactly?
A $99 one-time payment for Maker tier benefits locked in for life. Maker tier is the $49/year plan: unlimited domains, 25 GB storage, 500 transactional emails/day. You pay once, you never pay again. Fully refundable until V1 ships in Q3 2026.
Is my email end-to-end encrypted?
No. MailStoa does not offer zero-access encryption in V1. Mail is stored encrypted at rest on LUKS volumes, transit is TLS 1.3, but Khoa (as operator) has theoretical access to mail contents. This is documented honestly. If zero-access E2E is a hard requirement, use Proton. V3 planning includes a Vault tier with client-side key generation.
Do you train AI on my email?
No. Written policy: no AI model has access to customer mail bodies. No training, no summarization, no product improvement using mail content. This is a hard line.
What is the refund policy?
30-day full refund, no questions asked. Founding members: refundable until V1 ships. Annual subscribers: pro-rated refund for downgrade after first month. Annual cancel: refund unused portion if requested within 30 days of renewal.
Founding member — $99 lifetime
Maker tier benefits locked in forever. One payment, no recurring bill. Refundable until V1 ships in Q3 2026.
Limited to 100 members. If fewer than 10 join in 30 days, everyone is refunded and the project is killed.
