Google Groups alternatives for real mailing lists

Google Groups alternatives split into two real paths: groups.io, a hosted mailing-list service billed per member once you outgrow its free tier, and GNU Mailman 3, open-source list software that a host runs under your own domain for a flat fee. Google Groups itself has no single announced shutdown date, but its consumer and Workspace tiers have been reshaped often enough that most serious communities plan an exit rather than wait for one — and the two paths above are where they land.

This comparison is written for the moment right before that decision: a list owner who already senses the current setup will not carry a growing community for another five years, and wants to know what actually changes — in cost, in ownership, in day-to-day reliability — before committing to a replacement.

## where Google Groups runs out of road

Consumer Google Groups is free, and free is exactly why it is thin: moderation tools are basic, there is no reliable bulk-export API for a public archive, and a group's continuity depends on whoever created it staying reachable — if the founding admin leaves the organisation, access can get stuck. Google Workspace Groups for Business fixes some of that, but usually by requiring a paid Workspace seat for every member who needs full features, which turns a mailing list into a per-head software bill.

• No committed multi-year roadmap for the free consumer product — features have moved between tiers before and can again.
• Bulk export of a large archive is manual; Takeout was not built for mailing-list migration.
• Moderation and ownership are tied to individual Google accounts, not to the list itself.
• Workspace Groups for Business effectively bills per subscriber once you need its real feature set.

None of this is a single dramatic failure. It is a pattern of small, cumulative changes that a group's owners do not control — which is the actual reason to plan a move before you need one, not after an email arrives.

## groups.io: the closest like-for-like

groups.io is the hosted service most people mean when they say "a Google Groups alternative" — same core idea (subscribe by email, post to one address, browse an archive), run as a subscription rather than a free product. Its pricing is per member above a small free tier, so the bill tracks your community's growth directly.

Source: groups.io published pricing, as of July 2026.

Translate that into a growth curve and the shape becomes obvious: the Premium minimum covers you up to roughly 500 members ($20/month). Past that, the per-member rate takes over — at 2,000 members you are paying about $80/month, and at 10,000 members, about $400/month. The bill grows exactly when your list is succeeding, which is the opposite of what most communities want from their infrastructure cost.

## GNU Mailman 3: the open-source path

Mailman has been the reference mailing-list manager since 1998 — long enough that "will this still exist in ten years" is not a real question for it the way it is for a product roadmap. Mailman 3 pairs the mail engine with Postorius, a web admin UI for creating and moderating lists, and HyperKitty, a permanent, threaded, searchable public archive with a stable URL per message. Reply-To-List and per-list DKIM signing come configured correctly rather than left as a setting you have to find.

Because the software is open source, the actual cost is whatever your host charges to run it — and that can be a flat, per-list-count price instead of a per-member one. Managed Mailman 3 at mailman.hosting runs Single List at €9/month, Community (10 lists) at €29/month, and Institution (unlimited lists) at €69/month — net prices, excl. VAT, no setup fee, with 20% off on annual billing. The bill does not move whether your one list has 50 members or 15,000.

## the decision, side by side

you@lists:~$ cat 05-how-to-decide.txt

## how to actually decide

If a group is small, informal and genuinely disposable, keep using consumer Google Groups — the effort of migrating outweighs the risk for now. If it needs some structure (a wiki, files, a shared calendar) and its owners would rather not think about a mail server at all, groups.io is a fair, hosted middle ground; just budget for the bill to grow with the list.

If you want the archive to outlive any single vendor, if Reply-To confusion or spam-foldered announcements are already a recurring complaint, or if a per-member bill worries whoever holds the budget, Mailman 3 is the option whose pricing model does not change as the community succeeds.
