Email address requirements and recommendations
Last updated: Apr 1, 2025
These guidelines are designed to help you choose which email address to use with your Kraken account.
Email address requirements
The same spelling of an email address cannot be associated with multiple Kraken accounts (active, unconfirmed or closed).
Email address recommendations
We highly recommend using a free public domain email that you will always have access to.
We discourage the use of the following email domains as we often see clients lose access to them:
- •
Self-hosted domains
- •
University domains
- •
Internet service provider (ISP) domains
- •
Work domains (unless you're opening a business account)
