Hi Rob at the moment only the password reset email works. Are you able to check them please?
<p>Hello <%= @resource.email %>!</p>
<p>Someone has requested a link to change your password. You can do this through the link below.</p>
<p><%= link_to 'Change my password', edit_password_url(@resource, reset_password_token: @token) %></p>
<p>If you didn't request this, please ignore this email.</p>
<p>Your password won't change until you access the link above and create a new one.</p>
Confirmations dosen't
<p>Welcome <%= @email %>!</p>
<p>You can confirm your account email through the link below:</p>
<p><%= link_to 'Confirm my account', confirmation_url(@resource, confirmation_token: @token) %></p>
Email changed doesn't
<p>Hello <%= @email %>!</p>
<% if @resource.try(:unconfirmed_email?) %>
<p>We're contacting you to notify you that your email is being changed to <%= @resource.unconfirmed_email %>.</p>
<% else %>
<p>We're contacting you to notify you that your email has been changed to <%= @resource.email %>.</p>
<% end %>
Cheers Dave
