Email remains one of the highest-ROI marketing channels. Litmus reports an average return of $36 for every $1 spent, far ahead of pay-per-click and social media advertising.
For semiconductor companies, it is especially valuable because buying cycles are long, decisions involve multiple stakeholders, and technical information needs to be delivered clearly over time.
Yet many email programs still underperform. The most common reasons are straightforward: too much reliance on open rate, low click-through, and sending the same content to every contact on the list.
The 2025 data points to a clear conclusion. Email is still highly effective. But better results in 2026 will come from sharper segmentation, stronger content, clearer calls to action, and metrics that reflect real buyer intent.
Email Marketing Still Delivers Strong ROI
Litmus reports an average return of $36 for every $1 spent on email marketing. By comparison, pay-per-click advertising returns around $2 per $1 spent, while social media advertising returns about $1.75.

For B2B technology companies, this matters because email supports long, technical buying journeys. It gives companies a direct way to share product updates, application notes, datasheets, supplier announcements, whitepapers, and webinar invites without depending on platform algorithms.
Why B2B Buyers Still Prefer Email
Email’s value is not just in ROI. B2B buyers still prefer it for direct, relevant communication from vendors.
Recent research shows:
- 59% of B2B marketers consider email their top revenue channel
- 73% of B2B buyers prefer email for vendor communication
- 81% of B2B marketers say email newsletters are their most-used form of content distribution
- 79% of B2B companies say email is their most successful channel for reaching the right audience

For semiconductor, electronics, and deep-tech companies, that makes sense. Engineers, procurement teams, and business stakeholders often need different information at different points. Email remains one of the easiest ways to deliver that information consistently.
Where Most Campaigns Fall Short
If email works so well, why do so many B2B campaigns underperform? Three issues stand out: misleading metrics, falling click engagement, and poor segmentation.
Open Rate Is No Longer Enough
Many teams still treat open rate as a key measure of success, even though it has become increasingly unreliable. Apple Mail Privacy Protection has inflated open rates by pre-loading email content on Apple devices, whether or not the recipient actually reads the message. A reported open no longer tells you much about attention, relevance, or intent.
That shift is already reflected in how marketers measure performance. According to Litmus:
- Only 17% of marketers now use open rate as their primary KPI
- 29% use click-through rate
- 24% use conversion rate
For B2B technology companies, better indicators include clicks, content downloads, replies, demo requests, and conversions.
Click Rates Are Falling
Recent email data shows a clear pattern: open rates have risen, while click rates have fallen, which usually points to a problem inside the email itself. The message may not be relevant enough, the CTA may be unclear, or the next step may ask for too much too soon.
CTA design matters. Emails with one focused call to action tend to perform better than emails with several competing options. In B2B technology, low-friction actions often work best, especially earlier in the buyer journey:
- View product details
- Download a datasheet
- Read an application note
- Register for a webinar
These actions match how technical buyers evaluate. A hard sales ask too early often reduces engagement.

Segmentation Is Still the Biggest Gap
This is where many B2B email programs lose the most value.
A power electronics engineer and a procurement manager should not receive the same newsletter with the same framing and CTA. Nor should a technical evaluator and a business lead.
Yet many companies still send one broad campaign to their full list. The result is predictable: some content feels partly relevant, but not relevant enough to drive action.
Most companies already have the data to improve this. Click patterns, downloads, topic preferences, and past engagement all show what subscribers care about. Platforms like HubSpot and Brevo support behavioural tagging and interest-based segmentation as standard features.
The issue is rarely data availability. It is how that data is being used.
How AI Makes Email More Effective
AI is now built into most email platforms. Tools like HubSpot and Brevo already offer subject line testing, send-time optimization, and behavior-based personalization. The gap is no longer access to these features. It is whether teams are using them well.
For B2B technology companies, AI is most useful when it improves segmentation and relevance. It can help teams use behavioural data to send different content to engineers, procurement contacts, and business stakeholders based on what they engage with. Most platforms already have that data. The gap is in using it consistently.
AI does not replace campaign thinking. Audience, message, timing, and goal still need to be defined first. Where AI helps is in execution: testing variations, automating follow-ups, and personalizing content at a scale that would be difficult to manage manually.
What Better Email Marketing Looks Like in 2026
Stronger email performance will come from more relevant campaigns, not more campaigns.
For B2B technology companies, that means:
- Segmenting by role, interest, and buying stage
- Matching content to what each audience actually needs
- Using one clear CTA per email
- Focusing on useful content, not generic promotion
- Measuring clicks, conversions, replies, and downloads instead of relying on opens
This brings email strategy back to the basics: clear structure, real authority, fresh information, and content that is genuinely useful.
Conclusion
Email remains one of the most effective marketing channels for B2B technology companies. The ROI is strong, buyer preference remains high, and the format still fits long, technical buying journeys.
But good results now depend on more than sending regular campaigns. They depend on relevance, segmentation, strong content, and metrics that reflect actual engagement.
For semiconductor, electronics, and other technology brands, that means building email programs around how buyers really evaluate and decide.
At Anion, we help semiconductor and deep tech companies build email programs that are more targeted, useful, and effective. That includes strategy, segmentation, newsletter planning, campaign execution, content development, lead nurturing, and performance analysis. We work with technical brands to build email programs that support awareness, strengthen engagement, and move the right audiences closer to action.
If your email campaigns are active but not delivering the engagement or pipeline they should, the issue may be in the strategy behind them.
