They help businesses grow by improving revenue per send, conversion rates, and customer retention, mostly through better targeting, automation, and optimization.
Many businesses begin on a free plan to validate their audience. Agencies help transition from basic newsletters under a free plan to revenue-driving automation, segmentation, and lifecycle strategies.
According to the ZeroBounce report, 93% of people use email every day, and many say it actively improves their shopping experience.
For a small business, email marketing often delivers one of the highest returns compared to paid advertising channels.
Higher customer engagement leads directly to improved retention, repeat purchases, and lifetime value.
In Litmus' State of Email 2025 findings, 35% of marketing leaders report $10-$36 returned per $1 spent, 30% report $36-$50 returned per $1spent, and 5% report $50+ returned per $1 spent.
Unlike scheduled (non-automated) email campaigns, automated emails show:
In eCommerce datasets, automated emails drove 37% of email-generated sales while accounting for 2% of email volume, according to the Omnisend report.
By testing different email template variations and layouts, top email marketing agencies improve customer engagement and optimize conversion performance over time.
The Baymard Institute reports that the average documented online cart abandonment is 70.22%.
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.
The synergy between email and SMS marketing matters:
Using both strategically increases opportunities for touchpoints, meaning customers see your message in multiple places and multiple contexts, which improves brand recall and conversion likelihood.
Email marketing companies offer deep specialization in one channel (email), driving higher engagement and conversions through targeted campaigns and automation.
Full-service digital agencies offer a broad marketing strategy across many digital channels, aiming for unified brand growth and audience reach.
More specifically, these two types of agencies differ in the following:
| Email marketing companies | Full-service digital agencies | |
| Scope of services | Focus specifically on email as a channel. They build and manage everything tied to email performance. | Offer a broad suite of marketing and digital marketing services such as search engine optimization (SEO), pay-per-click (PPC) advertising, social media marketing, content marketing, web design/development, branding, and email marketing. |
| Depth vs. Breadth of expertise | Specialists; their entire skill set and resources are tuned to email performance, from list strategy to automated lifecycle campaigns. | Generalists across multiple disciplines. They manage many channels simultaneously but may not offer the same level of deep specialization on email alone. |
| Strategic focus and outcomes | Emphasizes long-term engagement and conversion via email automation, segmentation, and deliverability best practices. Their goal is to maximize email ROI specifically. | Aim for holistic digital growth. They integrate search, social, paid ads, content, and email into one unified marketing strategy to increase overall brand visibility, traffic, and conversions. |
| Integration with other channels | Specialist email agencies may integrate emails with CRMs, e-commerce platforms, and customer data platforms, but their primary metric is email performance. | Coordinate cross-channel strategies so that SEO, email, social, paid media, and other channels reinforce each other, helping brands create consistent campaigns |
The most-cited average benchmark is $36 returned for every $1 spent, which equals 3600% ROI.
Email marketing ROI also varies widely across industries.
The Litmus report shows the following ROI by industry figures:
Average ROI is high, but outcomes depend on execution
Litmus found that 41% of businesses use direct revenue attribution to email campaigns, while many still rely on engagement metrics like opens/clicks (59%).
DMA's Email Benchmarking Report from 2025 reports 98% delivery, 35.9% open rate, and 2.3% unique click rate, which is a useful context for what healthy programs can look like.
We have created a list of email marketing firms for you to choose from based on the different budget ranges they're offering:
| High budget: $50,000+ |
|
| Medium budget: $25,000-$50,000 |
|
| Low budget: $1,000-$10,000 |
|
Beyond the project budget, our agency directory lets you filter agency profiles by area of expertise, location, agency reviews, client types, and team size.
We suggest you ask email marketing firms the following questions before you sign the contract:
Rated 4.8 on Google and 4.7 on Trustpilot, DesignRush Agency Directory is a reliable resource for finding email marketing companies.

Hire an email marketing agency when your internal efforts aren't delivering the results you need, and you need to boost performance, save time, and improve ROI. Many small business owners begin with a free plan and basic campaigns, but hire an agency once email becomes a core revenue channel.
More specifically, you should hire an email marketing firm when:
The cost varies widely, depending on experience level, services included, list size, and campaign complexity. Email marketing firms usually charge $15 to $300 per hour, depending on the agency's expertise and location.
Per Email or Per Project
While free plans allow businesses to start email marketing at no cost, they typically limit the number of contacts, automation, and advanced analytics. Agencies, by contrast, focus on revenue optimization, making them a growth investment rather than a cost.
When choosing an email marketing firm, focus on measurable performance, strategic capability, and transparency. Here are the key criteria to consider:
Email marketing company prices are influenced primarily by:
If a business is still operating on a free plan, agency costs may initially include email marketing platform migration, list restructuring, or automation setup, which can increase onboarding pricing.
By understanding these factors, businesses can better compare proposals and choose an agency whose pricing matches the value and outcomes they expect.
