How to Choose the Right Email Marketing Agency

Creating an effective email marketing campaign takes time and effort. A good ecommerce email marketing company can handle this responsibility and help you create a campaign that drives spectacular results for your ecommerce business.

Before choosing an email marketing agency, you need to consider several factors, including:

1. Look for a portfolio

A portfolio offers insights into the company's work. Make sure you see the samples of an agency before deciding if it is a good fit. In addition, when researching email marketing agencies, look for client testimonials to evaluate how the company treats its clients. 

2. Ask about their email tools

Some ecommerce email marketing agencies use outside sources, such as Mailchimp and Klaviyo, while others use their own software. Whenever you contact an agency, you want to inquire about the tools they use to run their campaigns to ensure they have the right email marketing software for your business. 

3. Check their pricing page

You want to ensure that the email marketing agency pricing is within your budget. You can contact them to identify their package pricing and negotiate based on your marketing needs.

4. Check out their company values

You will spend a lot of time with the email marketing agency you settle for. So, you must ensure that their values align with yours to collaborate well. 

5. Look for additional services

As you research different email marketing agencies, see if they offer additional services. Along with email marketing, most companies provide other services, such as web design services and search engine optimization. You may decide later than you want to include additional services to help your email campaign perform better.


Email remains a critical marketing strategy for most businesses. So, choosing an email marketing service agency can make or break the success of your campaigns. Before you approach the email agency of your choice, ensure you have put together a clear set of objectives for your email marketing campaign or program. Additionally, ensure that you evaluate various aspects of the agency to ensure it is the right fit. At Thooja, we start by understanding your business, goals, and target audience. This way, we can provide custom campaigns tailored to the needs of your audience.
