They needed a smarter way to show up consistently, educate their audience, and turn interest into real conversations.
The “How”: MIG’s Role and Services Provided
Marketing Insider Group partnered with these teams to design and execute a repeatable demand generation system built around two core channels:
- Email marketing that delivers real value, not promotions

Email & LinkedIn Campaigns
I'm thoroughly impressed with how well the MIG writers do their research about our industry, our target audience, what they care about, and the keywords we should be targeting. The MIG team is incredibly flexible, pivoting quickly to adjust to our evolving strategy, and the content is always spot on, addressing what really matters to our audience. This approach has been incredibly effective at writing content that speaks directly to our audience's needs, focusing on results and practical benefits rather than technical jargon. And it has significantly improved our engagement and lead quality.
