Don't worry, your account is safe :-)
And we've given you free credit to make sure you don't need to renew until our new billing system is ready.
We're doing essential maintenance work for a major modernisation of our servers: read more here.
We think the transition will take until Wednesday to fully complete. ActiveInbox, as an app, has fully moved to the new servers, but we're doing billing and account management as a secondary stage.
If you're suffering any problems with ActiveInbox while this happens, please let us know ASAP and we'll get you fixed up. Just email us: firstname.lastname@example.org.
