Frequently Asked Questions
Will clearing the DB folder delete my emails?
No. Your emails are stored on your email provider's server, not locally. Clearing the DB folder removes local app data such as saved templates and signatures, but your emails will reload from your email provider's server after you relaunch Canary Mail.
Do I need to back up anything before clearing the DB folder?
Yes. Back up your data via iCloud before proceeding, especially if you have saved templates or signatures you want to keep.
Where can I download the latest version of Canary Mail?
You can always get the latest version from the Canary Mail downloads page.
What to Do Next
If clearing the cache resolved your crash, Canary Mail should now open and run normally.
