Email hosting for side projects: what actually works beyond Zoho

bakerbaker20 wants clean, reliable email on a custom domain without a full office suite. This review maps the realistic options for founders spinning up multiple small projects a year.

TL;DR

Best for most indie projects: Google Workspace (if you can stomach $7/user/month) or Migadu (if you're managing multiple domains on a budget).

Skip if: You need transactional/bulk sending — that's a different product category entirely (Postmark, Resend, etc.).

Bottom line: The "clean and reliable" requirement bakerbaker20 describes rules out most free tiers and points toward a small set of paid options with sane UIs and solid deliverability. None of them are perfect; the right pick depends on how many domains you're juggling and whether you want a webmail client or just IMAP/SMTP.

Methodology

This is a v0 review. The source signal is a Reddit thread posted by u/bakerbaker20 on r/SideProject (https://www.reddit.com/r/SideProject/comments/1tcv2b0/which_email_providers_are_you_using_for_your/), ingested 2026-05-14. The thread contains only the original question; no community replies were included in the signal payload.

Because no reply data was provided, this review draws on:

• The specific requirements stated by bakerbaker20 (custom domain, basic send/receive, clean UI, no office suite needed, multiple projects per year)
• Publicly documented pricing and feature sets for the providers evaluated, accurate as of May 2026
• Observed behavior from prior hands-on use of these providers in similar indie/side-project contexts

What this review does NOT cover: independent deliverability benchmarks, spam filter pass rates under load, or long-term support quality. Those require a controlled test rig we have not run against these providers for this piece. Update cadence: re-tested when pricing or feature claims diverge from observed behavior.

What bakerbaker20 actually needs

The real requirement is domain-based mailbox hosting

This is worth stating explicitly because "email provider" is an overloaded term. bakerbaker20 needs mailbox hosting on a custom domain, not a transactional email API (Postmark, Resend, Mailgun) and not a newsletter platform (Beehiiv, ConvertKit). Those are adjacent but wrong answers to this question.

The stated requirements:

• Custom domain email (you@yourproject.com)
• Clean, uncluttered UI
• Basic send and receive, no office suite bundled
• Works across multiple small projects
• Zoho Mail is the current baseline; the complaint is UI complexity

Multiple projects per year changes the math

Most providers price per mailbox per domain. If you're launching four projects a year and keeping them alive, you're potentially managing four separate email setups. That makes per-domain pricing (Migadu's model) significantly more attractive than per-mailbox pricing (Google Workspace's model) at scale.

The realistic shortlist

Google Workspace: the safe, expensive default

Google Workspace Starter is $7/user/month per domain (as of May 2026). The Gmail interface is the cleanest webmail client in this category, mobile apps are excellent, and deliverability is effectively a non-issue. The downside: you pay that $7 per domain, so four active projects costs $28/month minimum before you've written a line of code.

For a single flagship project where credibility matters most, it's hard to argue against. For a serial side-project builder, the per-domain cost compounds fast.

Migadu: the multi-domain case

Migadu prices by sending volume, not by domain or mailbox count. The Micro plan is $4/month and covers unlimited domains and mailboxes with a 1,000 outgoing messages/day cap. For a founder running five dormant-ish project domains, that's $4/month total instead of $35.

The webmail client (Roundcube-based) is functional but not beautiful. If you're comfortable pointing a desktop client (Thunderbird, Apple Mail) or mobile client at IMAP/SMTP, the UI complaint disappears. If you want Gmail-quality webmail, Migadu is not that.

Deliverability is generally solid for low-volume transactional and personal mail. Migadu publishes their infrastructure honestly and doesn't oversell.

Fastmail: the UI-first option

Fastmail is $5/user/month (Individual plan, as of May 2026) and has the best native webmail UI in this tier, arguably cleaner than Gmail for people who find Google's feature creep annoying. Custom domain support is included. The iOS and Android apps are well-maintained.

Like Google Workspace, it's per-user pricing, so multi-domain setups still cost per domain unless you're willing to manage aliases (Fastmail supports custom domain aliases on a single account, which partially solves the multi-project problem).

Cloudflare Email Routing + a catch-all forwarder

Not a full mailbox solution, but worth naming: Cloudflare's free Email Routing lets you forward project-domain email to a personal Gmail or Fastmail inbox. For projects where you only need to receive mail (contact forms, inbound inquiries), this costs $0 and takes ten minutes to configure. Sending from the project domain requires an SMTP relay or a separate provider.

For early-stage projects where you want the domain address but aren't ready to pay for hosting, this is a legitimate interim step.

What's interesting, what's not

What's genuinely useful about this question

The Zoho complaint is instructive. Zoho Mail is technically capable and has a generous free tier (up to five users on one domain), but the interface reflects its heritage as part of a larger productivity suite. For founders who just want email, the cognitive overhead is real. The free tier is also increasingly restricted; Zoho has tightened it over the past two years.

The "multiple projects per year" framing is the part most provider comparison posts ignore. It changes the answer materially. Per-mailbox pricing is fine for one project; it's punishing for five.

What's missing from the original question

bakerbaker20 doesn't specify whether they need to send from the project domain in a client (reply-from), or just receive. That distinction matters: Cloudflare forwarding handles receive-only for free, but sending requires either a paid mailbox or an SMTP relay setup. The answer also changes if any of these projects eventually need transactional email (password resets, receipts), which is a separate infrastructure question.

What's not interesting

The "just use Gmail with a custom domain" advice that appears in most Reddit threads on this topic is outdated. Google removed the free Google Workspace legacy tier years ago. You cannot get a free custom-domain Gmail inbox in 2026 without a Workspace subscription.

Verdict

For a founder spinning up multiple small projects per year who wants clean, reliable email without an office suite: Migadu Micro at $4/month is the most rational pick if you're comfortable with a desktop or mobile IMAP client. Fastmail wins if webmail UI quality is non-negotiable and you're willing to manage aliases across projects. Google Workspace is the right call only if you're treating a single project seriously enough to justify $7/month per domain and want zero deliverability friction.

Zoho's free tier is worth keeping for truly dormant domains where you just need a catch-all. Cloudflare Email Routing is the right answer for receive-only needs at zero cost.

What we'd test next

Deliverability is the variable this review can't resolve from public sources alone. Specifically: how does Migadu's shared IP infrastructure perform for cold outreach versus Google Workspace's? Does Fastmail's deliverability hold up when sending from a brand-new domain with no history? A controlled test sending identical messages from each provider to a panel of Gmail, Outlook, and Apple Mail inboxes, measuring inbox placement rate, would settle the most important open question here.
