Average Marketing & Digital Agency Email Benchmarks
Email marketing for marketing and digital agencies covers client newsletters, case study distribution, service promotion campaigns, thought leadership content, and new business outreach. Agencies typically have sophisticated email programmes because they understand the channel intimately, yet they also face intense inbox competition from other agencies and consultancies targeting similar audiences.
