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.

Frequently Asked Questions
Everything you need to know about MailmanHost. If you dont find an answer here, reach out to our support team.
-
Yes we can. If your Mailman 2 list is using some form of Mailman 2.1xx, then our migration script will be able to migrate your list settings, members and archives.
-
Yes you can. Since Mailman is access via the web and email, a domain name is needed. So if you have control of a domain name that is NOT being used with another web or email service, then you can use it with us. If it is being used with another hosting service, then we recommend the use of a subdomain (e.g. list.yourdomain.com) that is based off of the domain name that you wish to use. It is also possible to use a subdomain for web access and a domain name for email, as long as that domain name is NOT being used with another email provider.
Most of our clients uses a subdomain with our Mailman service.
-
To migrate a Mailman 2.1 list, we would need each list’s config.pck file (members,settings) and mbox file (archives). Those are typically found in the following locations:
config.pck:
/mailman_install_dir/lists/listname/listname.mbox:
/mailman_install_dir/archives/private/listname.mbox/Your current hosting provider can assist with retrieving those files. If you use cPanel to run your Mailman 2 lists, then doing a full cPanel backup will contain the above files.
-
Mailman 3 is the version Mailman users should be using now. Mailman 2 is no longer being developed and Mailman 3 has a long future ahead of it. We have vastly improved the user experience of Mailman 3 with our Affinity and Empathy apps. They are a great improvement over the default apps of Mailman 3: Postorius and Hyperkitty.
-
Yes you can. Just contact us to request a trial list to use. That will give you access to Affinity and Empathy.
-
Yes we can. We have a data center in London and Frankfurt. Just let us know of your need to be in one of these locations when you place your order.
-
Yes, we will offer a nonprofit discount
-
Most definitely. We can use Zoom to do a screen share and walk you through the features and functions of Affinity and Empathy.
-
Yes we do. We can configure all list traffic from your list domain to be signed with a verifiable DKIM signature. Using DKIM does require the client to set up the necessary DNS (TXT) record for the DKIM signature to be verified by other 3rd party providers such as Gmail and Yahoo. We do provide assistance for getting that DNS record set up.
