# Configure custom SSL certificate expiration thresholds

When we first launched Oh Dear, we had a fixed certificate expiration timer: 14 days. As soon as the expiration date came within 14 days, we'd start sending a daily reminder to _hurry up_ and renew those certificates.

Our first exception was made when Let's Encrypt gained more in popularity. We started notifying Let's Encrypt certificates _7 days_ before expiration date. The reason there was most auto-renewal systems will kick in 14 days before expiration date, our default threshold was _just_ at that edge and caused us to send renewal reminders right around the time most scripts would renew automatically.

This 7/14 split worked pretty well for a long time and served most of our customers. But we understand not all renewals are as simple as that.

Because internal rules or validations might take longer, we're adding a custom setting per site that allows you to inrease or shorten the threshold for when you want to start receiving renewal reminders for your <strike>SSL</strike> TLS certificates.

You can now choose any number of days you'd like, whatever suits your need. 

For Extended Validation certificates or Organization Validated certificates, we recommend a safety net of 30 days.
