Earth Day 2026: Our power, our planet – how your inbox can make a difference

This Earth Day, the theme “Our Power, Our Planet” reminds us that real change starts with the choices we make every day. Email is no exception: the average email generates about 4g of CO₂, and those with attachments can emit up to 50g—adding up to 410 million tons of CO2 from emails every year. Data center energy demands grew 12% over the last 5 years, with AI being a major driver, and most of these facilities still rely on fossil fuels to power our digital lives.

Users who were already logged in to webmail experienced fewer disruptions, but new logins and IMAP connections were significantly impacted. Our support system also lost operability during the outage.

We have since replaced the failed hardware, rebuilt the affected systems, and fully restored services with additional redundancy. No user data was lost, and we have taking immediate and longer-term steps to prevent a recurrence in the future.
