Maximum accounts per email address

[jalada]

Is there a maximum number of accounts per email address? There isn’t anything listed in the rate limits but it feels like something that might be limited.

I manage the letsencrypt-rails-heroku Ruby library which doesn’t persist account registrations between renewals; it just re-registers each time. It’s on our roadmap to persist account details, just wondered if an undocumented rate limit makes it a little more urgent!

There’s no limit. You can check the implementation of all rate limits here. This matches what’s described in the documentation.
