We're almost ready to offer the custom domain feature. First we need to make sure our script which is responsible for parsing emails works without any errors. To help us test it, please create an alias in your profile settings with new domain @7nd.me (read as send.me). And try to send email to new alias from other email address.
Our goal is to make sure that you are receiving emails without any problems. If you sent an email, but haven't received it, please contact me at email@example.com. Please provide the email domain you sent it from and the email text. It will help us tremendously to speed up custom domain delivery.
Also, the Minimum length for aliases has decreased to 3 letters. This will allow you to make a very short address.
