Frequently Asked Questions
Why do long-term EterMails cost more credits?
Vaulting an asset securely across decades is a serious commitment. The rising credit cost supports the compounding technical endurance required to protect your message: perpetual cloud storage hosting, continuous cryptographic encryption updates, multi-region disaster recovery backups, and maintenance against infrastructure decay over many years.
How much does a single credit cost?
Purchased individually, the base price is $0.50 per credit. However, we highly recommend purchasing one of our Package Plans or Subscriptions where credits are heavily discounted!
Where can I directly buy credits?
You can top-up your balance directly from the My Credit page after logging into your dashboard. It's fast, secure, and credits are available immediately.
Are there limitations on what I can send?
To ensure optimal storage and delivery through time, here are the generous limits per EterMail:
- Text: Up to 50,000 words
- Photos: Up to 9 images (compressed to 1080p quality)
- Video: Up to 10 minutes in length (1080p quality)
