FAQ
Frequently asked questions
Does Clesk Uptime offer blacklist monitoring?
No, deliberately not. Clesk Uptime focuses on availability, SSL, keywords and cron jobs. If you need DNSBL monitoring for mail servers, specialist services like HetrixTools are the right tool.
Why does the free plan check every 5 minutes instead of every minute?
The free plan is meant for getting to know the product permanently, not as a race for free limits. On Pro, Clesk Uptime checks every 60 seconds, for €79 per year including VAT.
What happens if I do not log in for a while?
Your account and monitors keep running and alerts keep arriving; there is no 90-day login requirement. Only a free account unused for more than twelve months may be deleted after an email notice with a grace period.
