What is a 'blank email'?

A blank email is basically an email without any content (no body and no subject).

Blank emails are used in BLAYNMAIL to make registration easy for subscribers.

How it works : Those who want to register for your mailing list send a blank (contentless) email using the "blank email" address you provide them. When that email reaches BLAYNMAIL, it sends a confirmation email back to the client containing a link to the registration form.

Why it's advantageous: Prospective subscribers can get a link to the registration form without having to visit your website. People who use internet on their mobile phones often have difficulty loading regular websites. Even if they have the ability, it is often expensive to do so. By sending a blank email from their mobile phone, they can easily access the registration form without having to load your website
