For list owners
Listserv hosting when your institution retires its list service
Last updated: October 2026
Listserv hosting means running your email list on a service that handles delivery, members and archives for you, instead of on a university or office server. In 2026 that matters more than usual: universities are retiring LISTSERV, Mailman and Lyris servers, and the lists that need outside members have to find a new home before the shutdown date.
No credit card · Members don’t need an account · Free assisted migration
Three ways members can find the list after the move: your own domain, the old address forwarded for 90 days, or a new @gaggle.email address. Compare the routes
- 17,000+ groups run on Gaggle Mail
- 4.8/5 on G2
- SOC 2 Type 1 audited

Why now
Why universities are retiring their list servers in 2026
Three things are happening at once. Lyris can’t keep up with email-security changes and is no longer supported. Mailman 2 has been end-of-life since 2020; here’s what end-of-life means for Mailman 2. And LISTSERV licenses are being dropped in favor of the groups that come with Google Workspace and Microsoft 365, which most campuses already pay for.
The pattern is the same everywhere: internal lists move into the campus tenant, and owners of everything else get a date. Deadlines tend to fall in June, August and December.

The part IT’s email doesn’t say
Which lists survive the move, and which get stranded
Campus groups work well when everyone on the list is on campus. Every other kind of list falls through. Here’s how a typical list server sorts out when it’s switched off.
Moves fine
to Google Groups / Microsoft 365 Groups
- staff-announce@ Everyone is staff
- chem-101@ Every student has a campus account
- faculty-senate@ A committee inside one tenant
If all your lists look like these, IT’s plan covers you. You don’t need us.
Gets stranded
needs a new home before the deadline
- class-of-1998@ Alumni, no campus accounts
- regional-chapter@ A society hosted “as a favor”
- neuro-consortium@ Members at 50 institutions
- alumni-book-club@ Needs digests and an archive
- field-volunteers@ Owner isn’t an employee
- birding-club@ People join by themselves
| Moves fine to Google Groups / M365 Groups | Gets stranded |
|---|---|
| Staff and faculty announcement lists | Alumni and class-year lists |
| Course and department lists where everyone has a campus account | Professional societies and regional chapters hosted “as a favor” by a department |
| Committee lists inside one tenant | Research communities with members at 50 institutions |
| Lists that need moderation, digests, a searchable archive, or self-service join | |
| Any list where the owner isn’t an employee |
The University of Iowa’s own guidance tells owners of these lists to find “another university or entity” to host them.
If your list is on the stranded side, the rest of this page is for you.
Where it can live
Your options for hosting a list the university won’t keep
Every honest option, with what it costs at three real list sizes and the catch that comes with it.
| Option | Fits when | 500 / 2,000 / 5,000 members | Catch |
|---|---|---|---|
| Ask another university to host it | A member works there and their IT agrees | Free | Same problem in five years; you own nothing |
| Run Mailman 3 yourself | You have a sysadmin and a server | Server + time | A different product from Mailman 2; you become IT |
| Google Groups (personal) | Small list, members happy to use Google accounts | Free | Every member needs a Google account; no custom address; opaque moderation |
| Groups.io | Hobby or technical community | $20 / $80 / $200 | Dated, busy interface; public-archive culture |
| Simplelists (single list) | IT wants a plain list server with SSO | $27 / $77 / $77 | Thin member experience; some deployments drop archives and digests |
| L-Soft ListPlex | You want LISTSERV itself, hosted | ~$150/mo + per-delivery | Same 1990s interface; priced per delivery |
| Gaggle Mail That’s us | A modern list the owner can run without IT | $50 / $200 / $500 Standard · free up to 200 | Not the cheapest above 2,000 members — you’re paying for the admin UI, deliverability and paperwork |

Minutes, not weeks
What to do before the deadline — a checklist
Moving the list takes minutes, and you can do it today — there’s no reason to wait for the deadline. Only two things run on the calendar: a second announcement a few days later, and the forward on the old address.
When
Today
One sitting · minutes
-
1
Ask IT for your exact shutdown date, and whether they’ll keep a bounce notice on the old address.
One email. Cornell kept a bounce notice running for five weeks after switching off.
-
2
Export your subscribers.
Step-by-step guides: export your LISTSERV subscribers and archive · export your Mailman members and mbox archive
-
3
Export your archive — the LISTSERV notebooks or the Mailman mbox file.
Same guides as step 2. Once the server is gone, so is the archive.
-
4
Write down your settings: who may post, moderation, digest, reply-to.
A screenshot of each admin page is enough.
-
5
Decide the new address.
Three routes, below: keep an address people recognize.
-
6
Set up the new list and import your members.
It takes minutes. Send us the archive and we’ll import it for you. Keep the old list running alongside the new one until shutdown day — don’t switch it off the moment the new one works.
-
7
Announce the new address to the old list.
Everyone is already on the new list — this just tells them where to post. The postcard at the top of this page is the whole message.
When
A few days later
Step 7 again: Send the announcement a second time.
Some members miss the first one. Two minutes, and it catches them.
When
Shutdown day
keep it for 90 days after
Step 8: Ask IT to forward or bounce the old address for 90 days.
Late posters find the new list instead of silence.
Rather not do the exports yourself? Email us your deadline and we’ll import the members and archive for you, free.
The new address
Keep an address people recognize
Members filter, whitelist and reply to an address they know. Changing it is the riskiest part of a move, so choose the route before you announce — then announce it twice.
Route 1
A domain your society already owns
Old address: alumni-1998@lists.example.edu
New address: list@yourassociation.org
The address outlives any host, including us. Best for societies and chapters. Redirect it to your list on any paid plan, or host it with us on Premium and Enterprise.
Route 2
A redirect from the old address
Old address: alumni-1998@lists.example.edu
New address: class-of-1998@gaggle.email
Forwarding for 90 days
If IT allows it, the old address keeps delivering for a while. Ask for at least 90 days, and get it in writing.
Route 3
The old name, a new home
Old address: alumni-1998@lists.example.edu
New address: alumni-1998@gaggle.email
Same list name, recognizable at a glance. Works on every plan, including free.

If you choose us
Moving to Gaggle Mail
Gaggle Mail is free for lists up to 200 members. Standard, at $0.10 per member per month, adds sending from members’ own inboxes and a searchable archive: $50 a month for a 500-member alumni list.
We do the move with you, free. Send us your LISTSERV, Mailman, Lyris or Google Groups export and we import the members and the archive. Members keep their own inboxes — no accounts to create, nothing to install. Most lists move over in minutes.
- Free assisted migration, archive included
- Moderation and daily digests
- A searchable archive only members can read
- Your own domain, if you want one
- 17,000+ groups run on Gaggle Mail
- 4.8/5 on G2
- SOC 2 Type 1 audited
- DPA included
“Such an improvement to our old Listserv! Very easy to administer.”
Running the decommission?
For IT teams: a resource for your list owners
If you’re retiring a list service, link your owners here. For lists with outside members we’ll do the import, and we can take a batch of them at once — email us the decommission date and a list of owners.
To: help@gaggle.email
Subject: Listserv retirement
Hi — our list server shuts down on Dec 31, 2026. Twelve lists have outside members; owners and list sizes attached. Can you take them as a batch?

Questions list owners ask
Can I keep my archive?
Yes. Export the LISTSERV notebooks or the Mailman mbox file and send it to us, and we import it for free. The archive stays private to the list, and members can search it on any paid plan.
Do members need to create accounts?
No. Messages arrive in the inbox they already use, with any email provider, and there is nothing to install. On any paid plan they post and reply from that inbox too; on the free plan they post from a web page.
Can I keep my @university.edu list address?
Only if IT keeps a forward running. Most owners move to a domain their society already owns, or a new @gaggle.email address with the old list name, and ask IT to forward or bounce the old address for 90 days.
What happens to moderation, digests and reply-to settings?
All three are there: moderate every post or only the members you choose, offer a daily digest, and send replies to the list or to the sender. Set them to match your old list before you announce the move.
How long does a move take?
Minutes for the list itself: create it, import the members and match the settings. Send us the archive and we import it for you; a very large archive can take a little longer.
What does it cost for a small list?
Nothing up to 200 members, and no card. Sending from members' own inboxes and searching the archive come with any paid plan: Standard is $0.10 per member per month, $10 minimum.
Can the university move several lists at once?
Yes. Email us the list owners and the shutdown date and we will import the lists as a batch. Enterprise customers get assisted migration as standard.
What if my list has more than 20,000 members?
A Gaggle Mail group holds up to 20,000 members, and above 10,000 we price it with you rather than on the pricing page. For a bigger list, L-Soft ListPlex or a self-hosted Mailman 3 are the realistic options.
