Settings
Threads
Control the number of concurrent connections.
| Plan | Max Threads |
|---|---|
| Air | 500 |
| Pro | 2,000 |
Higher thread counts increase speed but use more system resources and may trigger rate limits on some providers.
Timeout
Connection timeout per check attempt. Default: 30 seconds. Increase for slow networks or distant servers.
Retries
Number of retry attempts for transient errors. Default: 2 retries.
Only transient errors are retried: connection failures, timeouts, proxy errors, and TLS errors. Permanent results like invalid credentials, 2FA, or locked accounts are never retried.
Protocols
Enable or disable protocols for checking.
| Protocol | Plan | Notes |
|---|---|---|
| IMAP | All | Primary protocol for most providers |
| POP3 | All | Fallback for providers without IMAP |
| SMTP | All | Validates sending capability |
| Outlook | Pro | Microsoft domains |
| ABV | Pro | ABV.bg, gbg.bg, gyuvetch.bg |
| GMX | Pro | gmx.com, gmx.net, gmx.de |
Microsoft domains are automatically routed to the Outlook protocol when enabled. If Outlook is disabled or unavailable, they fall back to IMAP.
