Everything You Need to Know Before Hiring an Email Marketing Agency
How can an email marketing company help businesses grow?
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.
Email marketing agencies turn email into a measurable revenue channel
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.
They build automations that outperform "one-off" campaigns
Unlike scheduled (non-automated) email campaigns, automated emails show:
- 52% higher open rates
- 332% higher click rates
- 2,361% better conversion rates
In eCommerce datasets, automated emails drove 37% of email-generated sales while accounting for 2% of email volume, according to the Omnisend report.
Email marketing firms increase revenue with segmentation and personalization
- Segmented campaigns can deliver a 760% increase in revenue, according to Campaign Monitor.
- Among marketers who segment, 39% report better open rates and 24% report more sales leads.
By testing different email template variations and layouts, top email marketing agencies improve customer engagement and optimize conversion performance over time.
They recover sales lost to cart abandonment
The Baymard Institute reports that the average documented online cart abandonment is 70.22%.
- According to Contentsquare, cart abandonment emails often show strong performance: 39.07% opens, 23.33% CTR, and 10.7% conversion rate.
- Klaviyo's abandoned-cart benchmarks report $3.65 revenue per recipient and 3.33% placed order rate for abandoned cart flows.
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.
Expand reach with multi-channel strategies
The synergy between email and SMS marketing matters:
- Email is great for detailed storytelling, newsletters, and rich content.
- SMS excels in immediacy, alerts, and real-time engagement.
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.
What's the difference between an email marketing company and a full-service digital agency?
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 |
What is the average return on investment (ROI) of email marketing?
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:
- Retail/eCommerce/consumer goods: 45:1
- Marketing, PR, and advertising agency: 42:1
- Software and technology: 36:1
- Media/publishing/events/sports/entertainment: 32:1
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.
How do I find a B2B email marketing agency on DesignRush that fits my budget?
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.

What services do email marketing agencies provide?
They offer a suite of services that help businesses engage audiences, drive conversions, and measure email marketing campaign performance.
- Email marketing strategy and planning: Developing end-to-end email strategies, from audience targeting and segmentation to campaign calendars and lifecycle planning (e.g., welcome series, promotional campaigns, re-engagement flows)
- Email campaign creation and management: Designing email templates, writing copy and subject lines, and setting up campaigns with proper personalization. According to Litmus, newsletters remain one of the most common email types, used by about 68% of marketing teams in email programs, making it a staple service for many email marketing firms.
- Marketing automation: Around 50-71% of businesses use drip sequences, triggers, and customer journeys. Email marketing firms help set up and optimize these workflows for better engagement and efficiency.
- List growth and segmentation: Splitting lists by behavior, purchase history, or demographics is critical for relevance. Segmented campaigns can generate up to 760% more revenue than non-segmented campaigns, according to NPD Group.
- Deliverability and inbox optimization: Monitoring sender reputation, spam filters, and domain authentication (e.g., SPF, DKIM) to improve inbox placement, by reducing bounce rates and helping more emails actually reach subscribers.
- A/B testing: Running A/B tests on subject lines, content blocks, layout, and send timing to boost engagement metrics like open rates, CTR, and conversions. Agencies test multiple email template variations through A/B testing.
- Analytics and reporting: Providing dashboards and insights on open rates, click-through rates (CTR), conversion rates, and revenue attribution help clients measure ROI and refine future campaigns.
When should I hire this agency?
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:
- Your key email metrics, such as open rates, are significantly below 30-40%, or your click rates are under 2%.
- ROI from email is lower than expected compared with channel standards; the average ROI is around 3600-3800% (about $36-$38 return for every $1 spent).
- The internal team is stretched thin or inexperienced.
- You lack advanced capabilities like email marketing automation, segmentation, or personalization.
- You're currently using a free plan from your email platform, and you've hit subscriber limits, maxed out monthly send caps, and lack advanced automation features.
- You want measurable revenue growth.
How much do email marketing companies charge for their services?
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.
- Basic to mid-level agency: $1,000-$3,000/month for smaller businesses or limited campaigns.
- Standard full-service range: $2,500-$10,000+/month for ongoing work, including strategy, email automation, and reporting.
- Specialized email marketing services: $1,500-$3,000/month for 2-3 campaigns or $5,000- $15,000/month for enterprise-level management.
- High-end retainers can exceed $10,000/month when they include advanced segmentation, data integrations, or multi-channel automation.
Per Email or Per Project
- Per email: Roughly $250-$700 per campaign/email created.
- Per project: Starting around $1,000+ for a defined one-time engagement.
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.
What should I look for when hiring an agency?
When choosing an email marketing firm, focus on measurable performance, strategic capability, and transparency. Here are the key criteria to consider:
- Demonstrated performance results
Top email marketing agencies will show measurable outcomes, so look for case studies that include revenue lifts, conversion improvements, or ROI figures. Email marketing typically delivers $36 in revenue for every $1 spent, so agencies should tie results to actual financial impact. - Baseline benchmarks and gap analysis
Email marketing companies should compare your performance to current benchmarks and explain how they plan to improve your metrics. - Segmentation and personalization expertise
Segmented campaigns can see up to 760% more revenue than non-segmented ones, and personalized subject lines can boost open rates significantly. Look for clear segmentation strategies aligned with buyer behavior. - Automation and lifecycle strategy
Automated flows such as welcome series, cart abandonment, and post-purchase messaging are proven winners: automated email campaigns often outperform basic sends with higher opens and conversions. Choose an agency that builds and optimizes automation workflows. - Data-driven measurement and reporting
A B2B email marketing agency should establish KPIs, including conversion rate, revenue per recipient, and list growth, and report them regularly. Avoid vendors that focus only on vanity metrics like opens without linking to business outcomes. - Testing and optimization process
Continuous A/B testing should be part of their execution plan, as it's essential for growth over time. - Technical and platform expertise
Ensure the agency knows your email platform, be it Constant Contact, Klaviyo, Mailchimp, or HubSpot, and fundamentals like deliverability, authentication, compliance, and list hygiene. - Transparent scope and pricing
Know what email marketing services are included and what costs extra before you sign. Clear deliverables, timelines, and reporting expectations avoid surprises later.
What factors affect an email marketing firm’s pricing?
Email marketing company prices are influenced primarily by:
- List size and email volume
- Email marketing service and automation complexity
- Agency experience and reputation
- Frequency of campaigns
- Email marketing tools and integrations used
- Billing model and team composition
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.
