I want to start up an interesting conversation here. Many marketers over here rely on email as a source of reaching a wide range of demographic to sell their ideas. Because there is a reason behind it. According to Mckinsey and Company research email is still significantly effective at gaining customers than social media sources like Facebook and twitter.
But the problem comes when your email doesn't reach your recipients inboxes. So my question from all warrior fellows at this forum is to enlighten us with your experience that "How you guys avoid getting filtered into the spam box''.
It's a pretty basic question and different experiences shared on this topic can really help new marketers out here.
