Every once in a while a MailChimp customer will ask me, "Hey, MailChimp’s been great for keeping in touch with my loyal customers. But is there any way to buy or rent an email list from you guys, so I can promote my business to potential customers in my area?" That’s when I explain to them the perils of purchased emails, and the virtues of organically growing a permission-based list. I also tell them they could just look around for other local merchants who might have newsletters (or similar publishers in their industry), then partner with them. In the back of my mind though, I’ve always dreamed of creating a tool for MailChimp customers to make that process easier.
That tool would analyze your list, then scour the vast database of MailChimp customers, looking for similar publishers to recommend. But this idea has been on the back burner for years, because such a tool would require 1) a vast database of MailChimp customers, and 2) the ability to analyze it–fast. Well, going freemium back in 2009 kinda helped with requirement #1. We’re at 1.2 million users, and manage over 800 million email subscribers for them all. And launching our Email Genome Project helped with requirement #2.
Helloooooo, serendipity. Finally, we have all the pieces we need to build Wavelength: a MailChimp service that uses a massive amount of email data to help you find publishers who share something in common with you:
Wavelength doesn’t help you send a promotion to another list, and it definitely doesn’t give you other lists or email addresses. It simply shows you screenshots of other newsletters that some of your subscribers read. The goal is to help you contact those publishers and maybe form a relationship with each other. Ideally, you can link to each other and help each other grow your lists organically.
How Wavelength Works
Basically, Wavelength analyzes your MailChimp list, then compares it to all other MailChimp lists (really, really fast). It looks for subscriber overlap, then recommends similar publishers by showing you screenshots of the email campaigns they’ve sent.
For example, let’s say I own a local pub, and I’d like to find some email newsletter publishers in town to partner with.
