Welcome back to another episode of the Send & Grow podcast. This week, SparkLoop cofounder Louis Nicholls sits down with Emanuel Cinca, creator of the Stacked Marketer newsletter.

We jump straight into the good stuff, including:

• how to actually keep your email-list clean
• what audience growth channels are performing for Stacked Marketer right now
• what mistakes publishers make when trying to close sponsorship & advertising deals

... and much, much more.
