Frequently Asked Questions

Auto-renewal is an important feature, but it's not foolproof. Human error and technical glitches can still cause expiries to slip through the cracks. Even tech giants like Google and Microsoft have unintentionally lost domains due to expiry. Rexpiry adds an extra layer of security by monitoring expirations and sending valuable alerts, ensuring you stay protected against downtime and lost business opportunities.

If your domain expires, your website and email services will go offline. Most registrars offer a 30-day grace period for renewal without additional fees, but downtime is still possible. If the domain isn't renewed during this period, it enters a redemption phase, risking not just prolonged downtime but potentially losing the domain altogether. Rexpiry helps you avoid this by sending alerts before expiry, giving you plenty of time to renew and keep your online business secure.

If your SSL certificate expires, visitors will see HTTPS security warnings, which can quickly have a negative impact on trust and cause visitors to leave. Your data is exposed to risks without encryption, and your site's SEO rankings may drop due to insecure status. Rexpiry provides advance alerts so you can renew before expiration and maintain your site's security and credibility.

With ease of use as our top design principle, setting up Rexpiry is effortless. Just copy and paste your domain names into the system, click once, and you're good to go. It's that simple!

Yes. Rexpiry looks up your certificate issuer, SSL protocol, hash algorithm, Subject Alternative Name (SAN), and of course the validity dates.
