Email is the leading channel for securing leads, nurturing them, and a close second for converting them. It is also an integral part of the entire sales process, not just the early stages of content marketing.
Statistics show that nearly 4.5 billion people worldwide used email in 2025, and this number is projected to reach over 4.8 billion by 2027. This scale is one of the main reasons email marketing companies continue to deliver strong, measurable ROI across industries.
Out of all marketing and advertising channels, email accounts for 39% of usage, making it one of the top 5 most used channels, right after social media marketing with 52%, social media ads with 47%, and search advertising and SEO accounting for 40% and 39% respectively.
According to the ZeroBounce report, 93% of people use email every day, and many say it actively improves their shopping experience. For businesses working with email marketing firms, this daily engagement creates consistent opportunities to influence purchase behavior:
While having a catchy subject line is important, it’s only the second reason why people open your messages, the 2025 email marketing statistics reveal.
According to reports, 46% of people open their inbox regularly to check relevant emails, while 43% open it because of a catchy subject line.
21% said they open emails regardless of the content.
Only 14% interact with their inbox out of fear of missing out, and 7% presented other reasons for checking their emails daily.
Experienced email marketing agencies use open rate, click rate, delivery rate, unsubscribe rate, and bounce rate metrics to evaluate campaign health, engagement quality, and long-term list performance.
Open rate measures the percentage of recipients who open an email and reflects subject-line effectiveness and sender trust.
Average open rates typically range from 15% to 25%, though reliability has declined due to Apple’s Mail Privacy Protection.
Best practices include personalization, keeping subject lines under 40 characters, and A/B testing.
Click-through rate (CTR) tracks engagement by measuring clicks divided by emails delivered, while click-to-open rate (CTOR) measures clicks divided by opens.
A healthy CTR is usually 2%–3%.
Personalization is crucial, as 40% of respondents report frustration with irrelevant content, and emails with visuals can increase CTR by up to 300%.
Delivery rate indicates how many emails are successfully accepted by inbox providers.
The goal for everyone is to reach a 100% deliverability rate, but that’s usually unattainable because many emails end up in spam folders that users often don’t filter through.
With an expert B2B email marketing agency, you can expect to reach a 99% deliverability rate, assuming it follows best practices.
According to the ZeroBounce survey, 78% of users mark an email as spam if the email "looks like spam".
So, even if it doesn’t immediately go to the spam folder, an email will not be considered successfully delivered when the user doesn’t get to it.
As of 2024, Gmail and Yahoo require authentication (SPF, DKIM, DMARC) for bulk senders, making deliverability a shared responsibility between senders and ESPs.
Unsubscribe rates under 2% are considered normal, as Campaign Monitor suggests.
Segmentation, personalization, preference centers, and re-engagement campaigns for contacts who have been inactive for 6+ months help reduce churn.
Bounce rate should stay below 2% and include soft bounces (temporary issues) and hard bounces (invalid addresses).

Double opt-in, list hygiene, segmentation, and secured signup forms (e.g., reCAPTCHA) are key to maintaining list quality.
It's more effective than it’s been in years, according to Omnisend’s 2025 eCommerce marketing report, which shows global email open rates increased 6% year over year, reaching 26.6%, marking the fourth consecutive year of growth.
This sustained increase suggests that consumers are actively engaging with it, especially when messages are relevant and timely. This is why many brands continue to invest in trusted email marketing providers to manage performance at scale.
Click-to-conversion rates grew by 27.6%, indicating a shift in consumer behavior where people are clicking less impulsively, but when they do click, they’re far more likely to purchase.
In other words, email is attracting higher-intent, more purchase-ready traffic.
The revenue impact becomes even clearer when looking at automation.
The report found that automated emails generated 37% of all email-driven sales while accounting for just 2% of total email volume.
One in three people who clicked an automated email made a purchase, compared to one in 18 for scheduled campaigns. This highlights how modern email success is driven by strategy and timing, not sheer send volume.
Email also benefits from being a first-party channel, giving brands direct access to their audience at a time when paid media costs are rising, and third-party data is becoming less reliable.
With growing engagement, stronger conversion efficiency, and unmatched ownership of customer relationships, email remains one of the most reliable and scalable marketing channels in 2025, especially when paired with automation and lifecycle targeting.
We have created a list of agencies for you to choose from based on the three different budget ranges they’re offering:
| High budget: $50,000+ |
|
| Mid budget: $25,000-$50,000 |
|

DesignRush data shows that email projects can cost between $50 and $200 per hour. More clearly, projects start under $5,000 for 2-6 months and scale to $20,000–$100,000 and 12-24 months as complexity increases.
You can expect to get $36 for every $1 spent on email marketing, achieving a 3600% ROI.
According to an Omnisend report, buyers who click automated emails convert at a rate of 1 in 3, compared to 1 in 18 for scheduled campaigns, highlighting how strategic automation dramatically improves returns.
Email remains the top revenue-driving owned channel. The Omnisend report also found that automated emails generated 37% of email-driven sales from just 2%of total email volume, outperforming both SMS and push notifications in overall revenue contribution.
Email automation is the single biggest revenue lever in eCommerce marketing. Omnisend’s report shows automated messages outperform campaigns with:
This is why top email marketing agencies prioritize automation before increasing send volume.
They typically use a wide range of email service providers (ESPs) and marketing automation platforms, depending on the client’s size, industry, and technical needs.
