General Questions

Is MailDeck available on multiple devices?

MailDeck is available for the iPad (second generation and newer), iPad mini, iPhone, and iPod touch.

Which versions of iOS does MailDeck support?

MailDeck is compatible with versions of iOS 7 and beyond. If you are running an earlier version of iOS, a simple update to the newest version is recommended so you can enjoy the MailDeck email app. We recommend using the most recent version of iOS with MailDeck.

What email providers work with MailDeck?

MailDeck supports all IMAP email accounts including Gmail, Yahoo, iCloud, AOL,, and many more. Additionally, MailDeck supports Microsoft Exchange accounts with EWS enabled. Currently, we do not support ActiveSync Exchange accounts or POP email accounts.

What happens if MailDeck crashes?

No worries. Just restart the app and you should be up and running in no time. If for some reason the problem persists, please send us an email at feedback (at) or select the ?Feedback? shortcut in the side-bar menu within the app.

The MailDeck team is committed to bringing you the best email app on the market. While we are constantly working on new features, we would love to hear your ideas on how to make MailDeck even better. Please reach out to us by using the Feedback button within the app or at feedback (at)

Does MailDeck support Push Notifications?

Yes. To enable push notifications, go to your account settings within the app, select the email account for which you would like to receive push notifications, and tap ?Account Preferences.? Here you will be able to toggle push notifications on/off.

Why don?t my push notifications display any information about the message besides the account to which it was sent to?

In order to keep your messages private from other users who may be using your device, by default we only display the account to which the email was sent to. That way your messages are never shown to unwanted individuals. If you would like to show the subject of the message in your push notifications, follow the instructions below.

Can more information be included in push notifications?

The default push notification includes how many new messages you have and the account that they were sent to. If you would like your push notifications to include the subject of the email, you can enable this option in ?Account Preferences.?

Can I choose the sound for push notifications?

Yes. In ?Account Preferences,? you can select a sound for your push notifications.

Why am I receiving an error message that I have an invalid username or password?

If you are receiving this message, it could be that you have too many connections hitting the email provider?s servers. Most email providers only allow a certain number of connections from an account at any given time. Therefore, if your email account is connected on several apps, you may have exceeded the number of allowable connections.

Can I setup an alias with MailDeck?

Yes. To setup an alias for an account, first, you must setup the alias with your email provider via webmail. Then, go into your account settings for the account that you would like to add the alias to and select ?Account Aliases.? Add a display name and the email alias, and you can now send messages from that email address.

I just downloaded MailDeck and my inbox was not populated with all of my emails. Why aren?t all of my emails downloaded?

Upon initial sync, MailDeck will sync the most recent month (28 days) worth of emails for IMAP, and the most recent 3 weeks of emails for an Exchange account. If the account has less than 200 messages, MailDeck will sync all of the messages.

My Exchange account won?t connect, what should I do?

Do deleted emails get archived or are they permanently deleted?

When you delete an email within any of the inbox views, the deleted email will go to the Trash folder. That way if you accidentally deleted an email, you will be able to retrieve the email and move it back to your inbox. However, if you delete an email from the Trash folder, the email will be permanently deleted. If you wish to archive an email, tap the archive button (the folder with an arrow pointing down).

What does archiving an email do?

If you are using a Gmail account and you archive an email, it will remove the email from the inbox, but it will leave the email in your ?all mail? folder. When archiving with other accounts, the email will be moved to the Archive folder.

How can I delete a message or create a task from the ?List? view?

After checking the items above, if you still are not receiving push notifications, please email us at [email protected]

How do I import my Apple contacts into MailDeck?

Upon setting up your first email account, tap Contacts from the sidebar and you will be prompted for permission to access your contacts. Allowing MailDeck to access your contacts will automatically sync your contacts for use within the app. We do not compile this information or use this information in any way; it simply gives you quick access to the contact information you already have saved on your device.

If you previously denied MailDeck access to your contacts and have had a change of heart, tap on the ?Privacy? tab within your device Settings, select ?Contacts,? and toggle the MailDeck switch on.

When I try to delete an email, I am getting an error message. What do I do?

There are a few possible reasons that an email will not delete. First, please check to make sure that you have entered the correct email address and password for the account you are trying to delete an email with. Assuming you have the correct email and password, the most likely reason is because the folder mapping is setup incorrectly. To make sure your trash folder is mapped correctly, go into your settings, select an email account, and tap the ?Folders? option. Within the ?Folders? screen, select folder mapping and make sure that ?Trash? is correctly mapped to the trash folder. Another likely reason for emails not deleting is that your email account is setup in a foreign language. Currently MailDeck is not localized, so you will have to change the folder mapping of your account to English folder names.

How do I add custom signatures?

After purchasing the subscription, go into your settings and select the email account you would like to create a signature for. Once you have selected an account, tap ?Account Preferences? and select ?Signatures.? Now just add a signature name and your custom signature. To setup signatures on another account, simply select the account and follow the same steps. When composing an email, select ?tap signature to change? in order to choose a signature.

I bought the subscription, but I am still seeing ads. Why is this happening?

If you have purchased the subscription to remove ads and you are still seeing ads or you are unable to add signatures or an Exchange account, please close out of the app (double tap the home button and close the app) and restart the app. If this does not fix the problem, restore your purchase from the ?Upgrade? option within settings. If you are still encountering issues, please contact us at feedback (at)


How do I create a passcode for my user account?

When you are on the user account sign on screen, tap the settings gears in the corner of the user tile to access the tile settings. To enable passcode protection for your user account, toggle the ?Passcode? feature on and select a four-digit passcode. After confirming the passcode, select the timeout preference that suits your needs (logout immediately, after one minute, 10 minutes, or one hour) and hit the save button.

When I leave the app and open it again, why am I prompted to enter my password?

MailDeck allows you to select a timeout period for your account. The timeout options available include: On logout, instantly, 1 minute, 10 minutes, or 1 hour. To select the timout period, tap the settings gears on your User tile and select your option from the ?Request Passcode After? section.

I can?t remember my passcode. What do I do?

We offered the option of creating a passcode to ensure unauthorized individuals cannot access your email accounts. Unfortunately, as we do not track or store your passcode anywhere on our servers, that also means that MailDeck is unable to recover your passcode. Please be mindful of this when selecting your passcode. The alternative is to try all 10,000 possible combinations, although we highly recommend you choose a passcode that you will remember.
