Now I know checking or testing your subject lines sounds boring, but ECC makes it fun because ECC will score your subject lines, tell you what's wrong and give you the answer in seconds.
ECC transforms your subject lines into strong headlines that will make the spam filters jump for joy, so your emails land in the user's inbox.
Imagine getting 20%, 30%, 50% or more opens, signups, leads, and sales, just by making a few small tweaks to your emails.
