We host mailing lists, and we're genuinely good at it
Universities, libraries, research organizations, and hobby communities all trust their lists to us. We bring the harmony; you just hit send.
What working with us feels like
The same three things bring back research groups, colleges, and one-person hobby lists alike: it is easy to run, someone answers when you need help, and it stays up.
Just hit send
Configure the list once. After that, post to its address and our servers handle delivery, moderation, and archiving for you.
Real support, quickly
Mailman 2 and Mailman 3 are both fully supported. Requests get resolved fast, including mail-delivery issues and sending-IP reputation.
Reliable and powerful
Lists run on a flexible cloud with a 40 Gbps inbound and 1000 Mbps outbound network, SSD storage, and an enterprise-class database behind Mailman.
The suite that runs your list
Two applications we build ourselves, the Mailman core they sit on, and a way in from wherever your lists live now.
Fifteen years of lists that just work
Harmony Lists has hosted Mailman lists for over 15 years. Every list server runs in our cloud, in high-availability environments built for uptime. Mailman 3 hosting comes with two applications we build ourselves: Affinity for administration and Empathy for archives.
Pricing is honest and starts at $8 per list each month, with billing cycles you choose and clear invoices in a secure client area. No surprises, on the list or the bill.

Trusted by people who’ve experienced the difference.
I’ve had a day full of Zooms, including getting all of the list owners up to speed on the new Affinity/Empathy interface… which is awesome!! We love it and I think it will be a big hit.
With the much improved archives that Empathy now provides, we had an interesting effect: People actually look at them!
Affinity and Empathy both look good! The Affinity interface is very nice and very intuitive.
Finally, we can share photos using Empathy. Thanks again, it’s really nice!
Affinity looks great! The interface is quite easy to use.
When we unexpectedly learned that our last web host would not meet our list needs, Harmony Lists came to the rescue. Within 48 hours we had moved our large broadcast-only Mailman list of 25,000 subscribers. Harmony Lists's quick action and prompt attention was exactly what we needed to get back in business. Thanks, Harmony Lists, for a job well done!
My experience with Harmony Lists has been excellent. The scalable billing model is ideal for my specific setup and requirements. I look forward to continuing to use your services for a long time to come. Thank you for all your assistance in getting my mailing list started up successfully. So much better than my previous host!
I can confirm the reliability of Harmony Lists's Mailman hosting. Our lists have always run seamlessly, this is vital as this is our main point of contact with our emergency response riders and without it, it would greatly affect the service we provide and ultimately the lives that depend on our service.
