Pobox is a service of Fastmail, and we use their best-in-breed webmail service and applications. Some elements of webmail have changed since we have switched to their interface.
What's different about Fastmail
What's new with Fastmail
Fastmail has a full suite of access options -- webmail that's optimized for a range of device sizes, plus native apps for both iOS and Android.
The calendars and contacts include invitations, improved support for use on other devices, and drag-and-drop editing.
App support (both Fastmail's webmail apps, and within your own calendar and contact apps) is available today for users with standard passwords. App support for 2FA users is coming soon.
Delete for conversations can act on all folders. To match Pobox's behavior, it is currently set to act on the current folder only. Please be aware, if you switch to the "all folders" option, Sent and Mailstore Archive folders are included in "all".
