If you have a problem with Pegasus Mail or Mercury, the following resources are available to help you:

For both Pegasus Mail and Mercury:

  • Your first port of call is the Pegasus Mail and Mercury community web site, at This public resource brings together Pegasus Mail and Mercury users from all over the world, and is the primary place to find information about development, to get support, and to keep in touch.

  • There are public mailing lists available where the Pegasus Mail community meets, shares problems and solutions and generally discusses issues related to Pegasus Mail. These lists range from an extremely low-volume list for announcements about Pegasus Mail, to lists discussing specific versions of the program.

  • You can submit a request for technical support with Pegasus Mail to our support mailing lists, where experienced volunteers will attempt to assist you as time permits - send your request to

For licensed Mercury users:

  • If you have purchased a Mercury license, then you are entitled to a certain number of technical support incidents each year, handled directly by the author of the program. Send your request, including a detailed description of the problem you are seeing, to, making sure you include your license number in the subject line of your message. If you do not include your license number in the subject line, you may not get any kind of reply because of filtering processes we have had to implement in order to control access to the resource.

Please note that we cannot provide technical support by telephone, or by fax. We understand that many people may be more comfortable with phone support, but it's a simple resource problem - we're a quite small operation and telephone technical support is just too staff- and time-intensive to be practical. We apologize if this causes any inconvenience.
