DownNotifier.com monitors websites and sends alerts when they are down. It counts connection errors and HTTP status codes below 200 or above 399 as downtime, and can alert users when specified text is missing from a monitored page. SSL monitoring checks certificates once per hour and emails alerts about expiry within 10 days, incorrect operation, insecure configuration, or compatibility issues with older browsers. Its email deliverability validator checks SPF, DKIM, DMARC, and BIMI records; DKIM validation requires sending a test email. The site links to API documentation. The FREE plan is free and checks five websites every 10 minutes, with email alerts and SMS alerts requiring credits. PREMIUM costs 14.95 USD per year and includes 10 websites, one-minute checks, multiple contacts per monitor, SSL monitoring, extended reports, and unlimited history. PROFESSIONAL costs 99.00 USD per year and includes 25 websites, 20-second checks, 500 yearly SMS/WhatsApp credits, seven days of full monitoring logs, and WhatsApp notifications. The terms state a monthly service availability target of 99.7%. The monitoring FAQ also notes that passwords embedded in monitor URLs are not stored encrypted and are visible when editing a monitor.
