To select multiple emails for deletion, tap and hold an email until a check mark appears next to it. Then, just tap the other emails you want to select. But there’s an even easier way! Canary’s Bulk Cleaner feature allows you to quickly select and remove multiple emails automatically!
To use the Bulk Cleaner tool in Canary Mail, follow these instructions:
1. Tap on Home > More.
2. Choose ‘Bulk Cleaner’.
3. Scroll down so that emails are automatically identified and selected in your android device. More emails are selected as you scroll further. You can then select an action and it is applied to all selected emails.
