Share it. It lands in your inbox.

Yes, To-inbox is free to use, without ads. A one-time To-inbox Pro purchase unlocks up to 10 labels (free: 3), label forwarding, scheduled reminders and a note when sharing. No subscription.

No. With Google sign-in the app only asks permission to send email. It cannot read, delete or manage your messages.

Sending uses a Gmail account, but you can set any email address as the recipient.

A separate 16-character password you create at myaccount.google.com > Security > App passwords. 2-Step Verification must be on. You can revoke it at any time.

Yes. Turn on "Auto-send on share" in the app and choose a default label. Shared items then go straight to your inbox in the background.

Yes. In Account, under "Default recipient", enter that service's own email address (for example your Evernote address, or the email address of a Todoist project or Trello board). To-inbox then sends directly there. If you pick a label, it's automatically added as a hashtag to the subject (for example #to-read), so you can search or filter for it in that service. The regular Gmail labels via plus addressing no longer apply, since those only work when sending to a Gmail address. Want to send only certain labels to such a service and keep the rest in your Gmail? That is what Forward labels in Pro is for.

Yes, and usually it happens automatically. If your phone's backup is on, your labels, label settings and preferences come along with the Google backup. Install To-inbox on your new phone and everything is ready right away. Signed in with Google? Then your Gmail connection is back straight away too. For security, an app password is never included: you enter it once more. Prefer to do it yourself? Make a backup file under Menu > Preferences and restore it from the welcome screen.

Yes. The home screen shows an overview of everything queued up. From there you can send an item right away, change its time or delete it. If you delete one by mistake, you have a few seconds to undo it.

Yes, with To-inbox Pro: when scheduling, choose daily, weekly or monthly. You can get a notification once it has been sent.

Yes. In the app, swipe a label to the left under Labels. A custom subject is free, for example "Read: {title}". You can use {prefix}, {title}, {label}, {date} and {tag}. With Pro you can also choose "Other address" as the destination, for example the email address of a Todoist project, your Evernote address or a Trello board. That way +to-do goes to Todoist while +to-read stays in your Gmail.

Pro is a one-time purchase and simply stays active. If a purchase is reversed anyway, for example after a refund, all your labels are kept and you choose which 3 are active. Repeating reminders stop after their last send and forwarded labels go back to your own inbox. Your settings are kept; nothing is lost.

Yes. To-inbox sets an alarm for every scheduled item, so it is sent even when Android is in sleep mode, and sets it again after a restart. With Exactly on time (Menu > Preferences, under Notify for scheduled items, Android 12 and newer) it goes out to the minute; without that permission it can be a few minutes later.

In Menu > Preferences, turn on Labels in share menu. Your first labels then appear at the top of the share menu (3 by default; under Number of labels in share menu you choose 1 to 5, Android sometimes shows fewer): one tap and it is sent. It is off by default, so you only see the To-inbox icon. A long press on the app icon still shows your labels. On some phones it takes a moment before the share menu updates.

Tap an item for a menu: open the website, copy, resend or remove it. To clear everything at once, tap Clear above the list. Removed one by mistake? Tap Undo.

Under Menu > History, or through the link below the recently sent items on the home screen. You see your last 5 sent items; with To-inbox Pro up to 500, with search, a label filter and statistics. The history is stored only on your device and is included in your phone's backup. You can clear it at the bottom with Clear history; your emails in Gmail stay where they are.

Your phone is holding back sending in the background. Usually Data Saver is on: on mobile data an app may then only go online once you open it. Go to Settings > Apps > To-inbox > Mobile data and Wi-Fi and turn on Unrestricted mobile data usage. If battery usage for To-inbox is set to Restricted, choose Optimized or Unrestricted. The app warns you about this on the home screen, with a button to the right setting.

The app waits and sends the message automatically as soon as you're back online. If it still fails after a few attempts, it shows up on the home screen under Not sent, where you can retry with one tap.
