email marketing software without double opt in
I currently use MailChimp but this has double opt in. I know you can get around it if you import emails manually but I have a landing page which people sign up on and I want them to get the auto-responder right away without having to re-confirm their email.
Can anyone advise me on an email marketing tool that doesn't require this extra layer of verification?
Many thanks
