Is there any way for users to register, edit and cancel their subscription by themselves?

Yes, it is easy to add a registration, editing and cancelation form to your website. The form's html code is available on the BLAYNMAIL system. It's simply a matter of copying and pasting the HTML code into that of your website.

An alternative method is to simply add the link to the desired form (available in the BLAYNMAIL system), to your website for subscribers to click.

By providing these forms to your clients they will be able to register, edit and cancel their subscriptions by themselves.
