Mailing List Software (2026)
“Mailing list software” means two different things, and picking the wrong kind is the most common mistake.
- Discussion lists. Members email the list and everyone receives it, like a group conversation by email. Replies go to the whole list. Think open-source project lists or a club’s members list.
- Announcement lists. One sender, many readers. You write a newsletter or an update and send it to subscribers, who can unsubscribe but don’t reply to everyone. This is what most businesses mean.
Discussion list software
| Tool | Hosting | Notes |
|---|---|---|
| GNU Mailman 3 | Self-hosted, free | The standard for open-source projects. Web archives, moderation, digests. Needs a mail server you run. |
| Sympa | Self-hosted, free | Common at universities. Strong on large numbers of lists and permissions. |
| Google Groups | Hosted, free | The easiest start. Works as an email list and a web forum. |
| Groups.io | Hosted, free and paid | A modern hosted list service with calendars, files and wikis. |
If members need to talk to each other by email, use one of these. Newsletter tools don’t relay replies to the whole list.
Announcement and newsletter list software
| Tool | Hosting | Notes |
|---|---|---|
| Listmonk | Self-hosted, free | A fast, lean mailing list manager. Lists, templates and campaigns, no automations. |
| Sendy | Self-hosted, about $69 once | Sends only through Amazon SES. |
| Broadcast | Self-hosted, $250 once | Lists, segments, sequences with branching, double opt-in, an API. Sends through SES, Postmark, Mailgun or any SMTP. |
| MailerLite | Hosted, monthly | Inexpensive, with a website builder. |
| Mailchimp | Hosted, monthly | The best-known, with a large integration directory. Priced by contact. |
We make Broadcast, so weigh that row accordingly.
What to look for in announcement list software
Double opt-in and clean unsubscribes. Confirmed sign-ups protect your sender reputation, and Gmail and Yahoo require one-click unsubscribe on bulk mail.
Bounce and complaint handling. The software should stop mailing addresses that bounce or complain, automatically. Otherwise your sending gets paused.
Choice of sending service. Self-hosted tools send through a provider like Amazon SES. Being able to switch providers keeps you in control of cost and deliverability.
Segments and automation. Plain lists are enough for one newsletter. Once you want welcome sequences or to email only part of a list, you need segments and automations.
Your own data. Hosted tools keep your list on their servers. Self-hosted tools keep it in your database.
Frequently asked questions
What is the best free mailing list software?
For discussion lists, GNU Mailman or Google Groups. For newsletters and announcements, Listmonk if you can run a server, or Kit’s free plan if you want it hosted.
Can I run a mailing list on my own server?
Yes. Mailman and Sympa run discussion lists. Listmonk, Sendy and Broadcast run announcement lists and send through a service like Amazon SES, so you don’t have to run your own mail server for delivery.
Do I need my own mail server for self-hosted mailing list software?
For discussion lists like Mailman, you usually do, because the list has to receive mail. For announcement lists, no: the software sends through a provider such as Amazon SES or Postmark.
