Mailpro keeps your data only as long as it is needed for the services you use, your legal obligations, and our legitimate operational interests. The table below shows exactly how long each type of data is retained.
Retention schedule at a glance
| Data type | How long we keep it | Why |
|---|---|---|
| Account data (after voluntary closure) | 45 to 60 days | Allows data subject rights to be exercised before deletion |
| Inactive accounts (no login, sending, or billing) | 12 months — then deletion possible | Avoids indefinite storage of unused data |
| Campaign statistics (opens, clicks, unsubscribes) | Up to 5 years | Deliverability analysis and audit history |
| Hard bounce records | 1 year | Suppression list maintenance |
| Soft bounce records | 6 months | Temporary delivery issues |
| Billing and accounting data | Per Swiss legal obligations (typically 10 years) | Tax and accounting compliance |
| SMTP sending feature | Auto-deactivated after 180 days without sends | Protects against compromised credentials |
| SMTP after high-bounce activity | May be temporarily disabled after 30 days idle | Protects platform reputation |
Active accounts
While your relationship with Mailpro is active, your account data, contact lists, templates, and statistics remain available in your workspace. Backups are retained on the same Swiss infrastructure described in our data security page.
What happens after you close your account
Voluntary closure triggers deletion of personal account data within approximately 45 to 60 days. Some records are retained longer where the law requires — for example, billing data kept for Swiss accounting and tax obligations. You can also exercise your GDPR rights (access, rectify, port, erase) before the deletion window starts.
Inactive accounts and the 12-month rule
An account with no meaningful activity (login, sending, or billing) for 12 consecutive months is considered inactive. After that, the account and its data may be deleted automatically. Prepaid credits follow the same rule: log in at least once a year to keep them.
SMTP and bounce-protection rules
SMTP sending is automatically disabled after 180 days without an email being sent — you can reactivate it on demand. We may also temporarily disable an account after 30 days of inactivity if a high bounce rate is detected, to protect deliverability for everyone on the platform.
