There are no agents to install, no passwords or API keys to share, and no DNS or code changes. Add domains one at a time, or paste a list or load a CSV file, on any port, like example.com:8443."}},{"@type":"Question","name":"I use auto-renewal. Do I still need monitoring?","acceptedAnswer":{"@type":"Answer","text":"Auto-renewal can fail quietly after DNS changes, server moves or config updates. CertAvert checks the certificate your server is actually serving, so you find out before your visitors do."}},{"@type":"Question","name":"Is CertAvert really free?","acceptedAnswer":{"@type":"Answer","text":"Yes. The Free plan monitors up to 15 domains with no time limit and no card needed. If you need more, Starter ($50/year, 25 domains), Plus ($100/year, 50 domains) and Pro ($150/year, 100 domains) are yearly subscriptions you can cancel anytime."}},{"@type":"Question","name":"How does billing work for paid plans?","acceptedAnswer":{"@type":"Answer","text":"Paid plans are billed once a year through Paddle, our reseller, and renew automatically until you cancel. You can upgrade anytime and pay only the difference for the rest of your year. Downgrades and cancellations take effect at your renewal date, so you keep what you paid for. Every payment comes with a 14-day money-back guarantee. If a plan ends, domains above the new limit are paused, never deleted."}},{"@type":"Question","name":"Which emails will I get, and how often?","acceptedAnswer":{"@type":"Answer","text":"It depends on your plan: Certificate expiring: Free 30 days before; Paid plans 30, 14 and 7 days before; on Plus and Pro, or up to 3 days you choose. Certificate expired: Free Yes; Paid plans Yes. Certificate problem: Free No; Paid plans When confirmed, a reminder after 7 days, and when fixed. Domain name renewal: Free No; Paid plans 30 and 7 days before, and when it ends. Monthly summary: Free Yes (can be turned off); Paid plans Yes, to the alert addresses you pick. Sent to: Free Your account email; Paid plans Starter up to 3, Plus up to 5 and Pro up to 10 addresses. Also posted to Slack or Discord: Free 1 channel, the same alerts; Paid plans Starter 2, Plus 5 and Pro 10 channels, the same alerts. Short-lived certificates (under 90 days) are emailed later, at no more than a third of their lifetime (a quarter under 80 days), so routine renewals don't set them off."}},{"@type":"Question","name":"Which certificate problems send an email, and how fast?","acceptedAnswer":{"@type":"Answer","text":"On paid plans, we check again about 30 minutes after first seeing a problem and email you only if it is still there. If it isn't fixed, one reminder after 7 days, then one email when it is. Self-signed or untrusted certificate, missing intermediate: Yes. Certificate revoked by its certificate authority: Yes. Name mismatch, certificate not valid yet: Yes. Can't connect, timeout, name doesn't resolve, no certificate: Yes. Expired certificate: Its own email, right away. TLS versions, DNS records, other names: Shown on the Domains page only. Problem emails can be turned off for any domain in its Expiry alerts tab. The Free plan gets expiry emails only."}},{"@type":"Question","name":"Can my team get the alerts too?","acceptedAnswer":{"@type":"Answer","text":"Yes, on paid plans: Starter up to 3, Plus up to 5 and Pro up to 10 email addresses, for example you, a colleague and a shared team inbox. Each address gets its own email and is used only after someone at that address confirms it. The domain name renewal reminders go to every one of those addresses too, and you pick which of them also get the monthly summary, so your web designer or hosting person can see it. Alerts can also be posted to Slack or Discord channels (Starter 2, Plus 5 and Pro 10). Free sends alerts to your account email and one Slack or Discord channel."}}]}]}
