Best B2B Email Marketing Tools Listicle

Even as texting and other communication methods gain traction, email remains a powerful tool for marketers. Email offers your company a direct line to engage with prospects and customers. It allows you to build relationships, nurture leads, and drive conversions effectively. Just how effective is email marketing? One study concluded that the average ROI for B2B companies is $42 for every dollar spent. Another found that email open rates hover around 20% but are nearly double that for software providers.

That’s especially amazing when you consider that B2B SaaS marketing benchmarks for PPC click-through rate are just 1.6% across industries, 2.1% for SaaS. Just imagine what you could accomplish if you could multiply that success by 20X! However, the unique needs of SaaS companies—such as long sales cycles, complex customer journeys, and the necessity for personalized communication—require specialized B2B email marketing tools. To meet these needs, SaaS companies must partner with a platform that offers robust features tailored for their specific challenges.

Just like when you’re shopping for the best CRM for B2B SaaS, you’ve got to do the research required to make an informed choice to select the right email platform for your company. Here are some recommendations to get you started:
