Backup & Restore
New Campaign
← Settings › Backup & Restore
What's included in a backup: Campaigns, leads, templates, sender accounts (SMTP/Gmail/Outlook credentials), AI settings, all app configuration, variations, and knowledge base.
Not included: DNS records (SPF/DKIM/DMARC) — these live in your DNS provider and are unaffected by backup or restore.

Restore Backup
Upload a .zip backup file
Upload a previously downloaded backup to fully restore your app — campaigns, senders, leads, settings, and all AI-generated content. The current database is automatically saved before restore.

Only .zip files exported from this app
⚠ Restore will replace all current data. The existing database is saved as mailer.db.before_restore in the app folder.
Clear Database
Danger zone — removes all data
Deletes all campaigns, leads, sender accounts, templates, settings, and AI data. The database schema is preserved so the app continues to work. A pre-clear backup is saved automatically.

This cannot be undone unless you have a backup. Download a backup first.
