I recently bought a domain and set up a small website.
I'm offering a free eBook that I prepared on the website in exchange for email addresses.
The website is only a few days old and people have been signing up. Till now I've been handling the emails manually.
Since I'm a full-time student and spend pretty much all my income from freelancing on tuition and the bare necessities, I can't invest any more money into my site.
My question is - is there any free service that I can rely on to collect emails and send them an automated response?
