Companies appear willing to invest more heavily in their email marketing channels next year, according to a study conducted by StrongMail in conjunction with Zoomerang.  As they do so, their focus will be one, or more, of these three areas: increasing subscriber engagement, improving segmentation and targeting–and growing opt-in email lists.

QR Codes, which are moving beyond their straight marketing applications, can help with that last point, according to a blog post in Bronto.

Steven DuBois walks readers through steps to take to grow a list via QR Codes. Among these is tracking. "On the webform of the QR code be sure you can assign a source to the user that signs up on your email list using the QR code. This will provide you insight on the quality and value of the user," he says.
