If you’re considering hiring email marketing agencies, you might wonder if it’s worth the investment. After all, you can just handle email campaigns yourself with software, right?
While email marketing software helps you send campaigns, working with an email marketing agency provides more than this. You get strategic expertise, proven tactics, and insights backed by real data.
Email marketing agencies offer access to professionals who understand what works and what doesn’t. They can create strategies that cater specifically to your business needs.
This article covers 17 of the top full-service email marketing agencies in 2026. We’ll show you what makes these email marketing agencies stand out and why they could work for your business.
Combine Omnisend’s powerful automation with email marketing professionals

However, many top email marketing companies also handle automation, segmentation, A/B testing, and analytics. Some email marketing agencies even manage deliverability to ensure your emails land in inboxes instead of spam folders.

When you partner with the right email marketing agency, you can launch email marketing campaigns that align with your brand goals.

You need to partner with the right email marketing agency to maximize your campaign’s returns. It’s important to assess each agency based on key factors. Here are some essential criteria to keep in mind when making your decision:
Experience and expertise: Look for an email marketing agency with a proven track record in email marketing. Check how long it’s been in the industry and whether it has experience working with businesses similar to yours.
Team expertise and size: Look for an agency with a diverse team. The best email marketing companies have strategists, designers, copywriters, and deliverability experts working together.
Deliverability and technical skills: The best email marketing agencies will have a solid plan to fix deliverability issues. If you’re seeing low open rates, a good agency knows how to diagnose and resolve the problem.
Platform expertise: Verify that the agency is proficient in the email service provider your business uses. Some email marketing agencies specialize in specific platforms like Klaviyo, Omnisend, or Mailchimp.
Pricing and transparency: Compare pricing structures to ensure they fit your budget. A reliable email marketing agency should offer clear pricing without hidden fees. Look for flexible plans that align with your needs.
Industry specialization: Determine if the agency has experience in your specific industry. Email marketing agencies with expertise in your sector are more likely to understand your audience and create customized campaigns.
Client reviews and reputation: Read reviews on platforms like G2, Trustpilot, or Capterra to find out what other clients have to say. High ratings and detailed testimonials might show that the email marketing agency is trustworthy.
You should also check community forums for informal feedback. This helps combine formal reviews with community insights. For instance, see this review written by a client of Add People on Trustpilot:
Outsourcing your email marketing to a marketing agency can help you tap into the maximum potential of email marketing.
Hiring an agency tends to be most worthwhile if your business sends emails frequently and relies on email for a significant portion of revenue. In these cases, the expertise and time savings can drive substantial growth that justifies the investment.
However, if you only send newsletters occasionally or have a small email list, you might manage in-house first and consider an email marketing agency as you scale.
Meanwhile, many businesses wonder, “How much do agencies charge for email marketing?” before making their decision. Consider the pros and cons of hiring an email marketing agency compared to managing email marketing in-house before you seal the deal.
Here’s how they compare:
Hiring an email marketing agency
Pros
Expertise: Email marketing agencies bring experience, strategy, and data-driven insights that help you avoid costly mistakes and bring results
Time-saving: A marketing agency can handle most marketing aspects, freeing your in-house team for other tasks
Advanced tools: You’ll have access to advanced email marketing software without purchasing separate licenses
Access to the latest strategies: Email marketing agencies stay current with evolving trends in deliverability, automation, and AI personalization
Cons
Cost: Because they bring expertise, they can be expensive, especially for small businesses operating on tight marketing budgets
Less control: You may have less direct input on content and strategy decisions if you fail to communicate regularly
Handling email marketing in-house
Pros
Full control: You have complete control of content, strategy, and execution without needing external approvals for changes
Cost-effective: Avoid agency fees and allocate resources based on your budget while building internal capabilities over time
Brand familiarity: Your internal team understands your brand voice and audience better
Cons
Limited expertise: An internal team may lack specialized knowledge or experience in certain email marketing aspects
Tool limitations: You may need to invest in and learn how to use email marketing tools
Time-consuming: Doing it all internally can pull your team away from other tasks and strategic priorities
Tips for working with an email marketing agency
To cultivate a highly effective and mutually beneficial collaboration with your email marketing agency, here are some expert tips you can consider:
Set clear goals from the start: If your goal is to increase sales, improve customer retention, or something else, make sure to communicate it clearly. Knowing which metrics you’d like to improve helps the agency design the right strategy.
Define scope and budget upfront: Discuss pricing models, whether it’s project-based, retainer, or performance-based, to ensure transparency in all cost-related matters. Most email marketing agencies will hold a discovery session where you can outline your needs and ask about their pricing structure.
Communicate regularly and openly: Consistent communication on progress, insights, and strategy adjustments ensures that both parties are on the same page throughout the collaboration. This can minimize misunderstandings and build a shared understanding of goals and processes.
Be open to expert recommendations: An agency has a team of experts, so trust their advice and recommendations. Email marketing agencies bring experience from many campaigns. Testing their ideas could lead to better engagement and conversions.
Provide timely feedback and approvals: You should respond on time to email marketing agencies so you stay on track without delays, as this can derail campaign timelines. Provide prompt feedback and approvals on designs, copy, and campaign strategies to keep projects moving smoothly.
Establish KPIs and review progress: Set up regular check-ins to review performance reports and track key performance indicators, including metrics like open and conversion rates. This keeps everyone accountable and allows for data-backed strategy adjustments.

Factors affecting cost include company size, number of emails sent, subscriber list size, and campaign frequency.
3. Which is the best email marketing company?
If you’re asking what the best email marketing agencies are, the answer depends on your specific needs. Look for an agency with an impressive portfolio, proven results, and expertise in your industry.
