Email is like gold. Once you have an email address, you can contact this person pretty much for free. Data shows that email marketing generates $42 for each $1 invested. And it makes sense! Everyone uses email. Your business has probably built an email list and with the right email marketing agency, it can be turned into a profit-generating machine.

Unfortunately, most companies fail at using email marketing effectively. Their emails go to spam, their content doesn't produce sales. They don't have the knowledge to run effective email marketing campaigns.

That's why even multi-8-figure brands work with one of these email marketing agencies.

How to Choose the Perfect Email Marketing Agency?

Not every email agency is a good fit. Based on the type of business you run, you have 2 kinds of email agencies to consider.

B2B Email Agency

B2B email marketing is vastly different than B2C email marketing. These agencies focus on sending cold emails to enter new prospects into a sales funnel.

If you don't have an email list or you've purchased a lead list - you're essentially sending cold emails. In these cases a B2B email agency is the only choice for you. As cold emails have a vastly different approach from regular email agencies.

However, if you've built an email list from having users abandon checkouts or fill out lead forms, a B2C agency will be a better fit.

B2C Email Agency

B2C email agencies use your existing email list to nurture & convert your email list. This is a good fit if you run an eCommerce brand or a SaaS company.

Once you've picked the right email agency type, answer these 6 questions to ensure you find a quality partner.

1. Do they have a real plan?

How does your email agency know they can help, if they haven't done an audit? Or they haven't built a real plan of improvement.

Great email marketing agencies won't even offer prebuilt packages. They create custom-tailored solutions based on your email setup and results.

The quality of the plan is an indicator of the quality of their work.

Your plan should include deliverables, timelines, and expected results.

2. What services do they offer?

It often seems tempting to work with companies that provide an array of services: paid ads, social media marketing, and email marketing. But that's rarely a good idea.

A master of everything is a master of nothing. Agencies providing all services cost an arm and a leg while delivering subpar results. The best agencies specialize in 1-3 services. Any more than that and it becomes impossible to work with multiple clients with multiple services.

3. Are their emails persuasive?

Content is key to success with email marketing. So when you're deciding upon your preferred email partner, always be sure to see examples of their work.

4. Have they worked with brands like ours?

Make sure the agency you decide to work with has a great reputation & portfolio. Agencies who've worked with brands similar to yours would have experienced all the difficulties before.

This will allow them to solve issues quicker and deliver better results faster. You can often see this on the company's website or by asking questions to their team.

5. What are their results?

Each great agency will be able to share case studies of brands they've helped. Great results superseded any words.

If a company cannot show any clear case studies or results, they may not be trusted.

6. Know Their Team

Before you sign a contract, ask questions about their team. Often on sales calls you may be talking with a business owner. You may think they're a good fit, but sometimes they've hired subpar contractors and outsourced all the work to them.

Great companies will be able to give you information on the team and their experience. If you can trust their team, you know their company can take good care of you.

Reasons to Hire an Email Marketing Agency

Email marketing is important, but hard. Most brands have little to no experience when it comes to creating email strategies, writing, and designing emails. Brands often see subpar results because of the lack of knowledge limiting them from getting better results.

You can be sure our email marketing agency will hyper-optimize every little aspect of your business preventing you from losing money.

  • New product launches
  • More marketing adspend
  • More A-list team members

Working with us is easy. Each month we'll create a content calendar with email ideas for you to approve. Then we'll write all the copy and create the email designs and you'll be able to fine-tune the copy & the design to your liking.
