Can I use Postbox for Gmail, Yahoo mail, AOL mail or other webmail accounts?
You bet! Postbox lets you keep existing email addresses and accounts. In fact, we make any webmail account even better by making it easy to find and use almost anything from your webmail accounts.
Does Postbox work like Gmail?
Postbox and Gmail work beautifully together, a match made in heaven. But there are some important differences between Gmail's webmail interface and Postbox that you should know about. Please see our Using Postbox with Gmail page.
Can I use Postbox to get mail from my Exchange server?
Postbox currently supports POP3, IMAP, and SMTP protocols, so if your administrator has those protocols turned on in Exchange, then you can use Postbox to send and receive mail from those servers. Postbox does not currently support native Exchange protocols.
Does Postbox include a calendar?
Not directly, but you can use the Lightning calendaring extension within Postbox, which provides an integrated calendaring experience. Please see our visit our Lightning page to learn more. Note: Lightning is developed by a third party, and as such, is not supported by Postbox, Inc.
Are there add-ons available for Postbox?
Yes! Please see our Add-ons Center for a list of third party add-ons developed for Postbox.
Do you provide support for add-ons?
Postbox does not provide support for the functionality of third party add-ons, as these are not developed by Postbox. If an add-on isn't working as you expect, or if an add-on is causing problems within Postbox, we recommend disabling the add-on, or contacting the add-on developer directly for assistance.
Do Mozilla add-ons work in Postbox?
Unmodified Mozilla add-ons do not work within Postbox at this time. Developers of existing Mozilla add-ons need to port their add-ons to Postbox. Sometimes this can be as simple as changing a few parameters, such as product, version, etc., other times the porting effort may be more complex.
What if I do not see my favorite add-on listed?
We work with extension developers as much as possible, but if there is a particular add-on that you really like, our suggestion is always to contact the add-on developer to have them port their add-on to Postbox.
Where can I find help?
We have found that the best way to service Postbox customers is to help them, help themselves. As such, we have a number of support resources available to you.
Since Postbox is based on Mozilla code, you can search the popular MozillaZine forums to see if any questions are similar to the ones that you have.
Try searching Google, as it is very likely that other people have posted similar questions/answers to the web, particularly for issues that relate to POP or IMAP protocol issues that are common to all email clients.
Additionally, we're currently evaluating a number of different Forum solutions that will enable Postbox users to collaborate and share ideas. We thank you in advance for your patience as we work towards a solution on this front.
Please note that we do not offer one-on-one support offerings to new users. All support efforts are currently dedicated towards providing better documentation and self-help solutions so that users can more quickly find the answers they need.
What does the single-user license cover?
Postbox is licensed on a "per person" basis. A single-user license allows you to install Postbox on as many computers that you personally use. For example, you can install and use Postbox on your computer at home and/or your laptop at work.
IMPORTANT: Purchases made through the Mac App Store can only be run on Mac computers. If you need to run Postbox on both Mac and Windows, you MUST purchase through the Postbox Store. We cannot issue licenses to Windows users if you purchase from the Mac App Store!
What is your upgrade policy?
If you purchased Postbox from the Postbox Store or the MacLegion Fall 2011 bundle on or after August 15th, 2011, you will automatically be upgraded to Postbox 3, as the license key that was issued to you is in fact a Postbox 3 key.
If you purchased Postbox 1.x or Postbox 2.x from the Postbox Store prior to August 15th, 2011, then you are eligible to upgrade to Postbox 3 at a discount.
If you purchased Postbox from the Mac App Store, then you are currently not able to upgrade to Postbox 3 at a discount. As a reseller of Postbox, Apple does not provide a mechanism for software upgrades, however, we are hopeful that they will implement this capability in the future.
Updates within a major version (e.g. from 2.0 to 2.0.1, 2.1, etc.) are provided free of charge.
Does a license cover both Mac and PC?
Yes! Your Postbox license will work on a Mac, PC, or both! However, you must purchase from the Postbox store to receive a license that works on Windows. We cannot issue licenses to Windows users if you purchase from the Mac App Store!
Do you offer discounts for seniors, non-profits, or other groups?
Not at this time. But we encourage everyone to become a Facebook Fan, follow us on Twitter, or subscribe to our blog to learn about special deals!
Do you charge taxes?
Sometimes, depending upon where you live. Taxes are calculated automatically by our e-commerce provider (FastSpring), and once you enter your address, the e-commerce system will summarize the applicable taxes (if any) on your order confirmation screen prior to purchase.
Can I try Postbox before I buy?
Absolutely! Try Postbox for free for 30 days.
Do you offer a guarantee?
Purchase with confidence! We know that Postbox will provide a terrific email experience for you, so in addition to our free 30-day trial, we also offer a 60-day money-back guarantee. That's up to 90 days to determine if Postbox is right for you!
If for any reason you would like a refund, simply submit a refund request within 60 days of purchase, and we'll promptly refund your order -- no questions asked!
If you purchased Postbox from the Mac App Store or through a bundle deal, please refer to the refund policies for those retailers.
How do I retrieve a lost license key?
Please enter the email address used to purchase Postbox on this form and we'll send your license key to you right away.
