Forrester periodically surveys marketers to get a pulse on how they employ the most veteran of tools in their interactive toolkits — email. We've found that more business-to-consumer (B2C) than business-to-business (B2B) firms use email; email budgets were idle in 2011; and email marketers expect email to get more effective, even though they don't comprehensively employ best practices yet.

This report describes the email marketing landscape for interactive marketers.
