B2B Email Marketing Statistics and Trends

Email remains the backbone of B2B digital communication, even as buying journeys get longer and more self‑directed. In 2025, there are around 4.6-5 billion email users globally, with 99% checking inboxes multiple times per day, giving B2B marketers unmatched, always‑on reach into decision‑maker workflows. Studies consistently show that around 59% of B2B marketers rate email as their highest revenue‑yielding digital channel, and average ROI estimates cluster near $42 for every $1 spent.

From the buyer side, email is not only tolerated but preferred. Between 73% and 77% of B2B buyers say email is their main or preferred communication channel with vendors, often by more than double any other channel. Subject line personalization can drive about a 9% uplift in opens, while sender‑name personalization (a real person vs a generic brand) can lift opens by around 27%. Even as privacy changes inflate open metrics, deeper indicators such as CTR (2-3.2%), CTOR (5.63-7.4%+), and conversion rate (≈2.5%) show that well‑targeted B2B email is still capable of moving pipeline at scale.
