I have a Rails application and I have a button which lets the user send an email using mailto.

Here is the code:

<%= button_to('e-mail Us', href="mailto:<email address>?subject=Private Lessons", :class => 'btn btn-large btn-success') %>

It’s working fine, but when the email opens, the body of the email has this in the body of the email.

I definitely don’t need it in the email. What can I do to have this not appear?

Thanks

You could use the mail_to helper method instead:

<%= mail_to "test@test.com","email-Us", :subject => "Private Lessons" %>
