I´ve been using GetResponse for many years now, after trying several other Email Marketing Programs. I choose it for the following reasons, where the first one is the most important:1) Landing in the normal Inbox of my clients, so reliable high delivery percentages.(Not in the SPAM/Promotions Folder)2) I have created my website and a lot of landingpages with GetRespsone as well. So, one subscription ,no integration needed, all in one tool.
