Hiya, I'm looking for a tool, online I imagine, that will help me send bulk HTML emails. This will be a newsletter, so some sort of automatic opt-out function would be helpful. Extra helpful would be a way of integrating a signup box on my website for the newsletter. I'm hoping to pay as little as possible, while maintaining the highest quality - so, - no branding on emails sent out - effective spam-box avoiding I'd be very grateful to hear people's recommendations, experience, and any pitfalls to look out for etc. Thanks
