What is an email marketing service?

An email marketing service is essentially a piece of software that enables your company to send emails so you can engage with customers and market your goods or services more effectively. There are a wide range of plans to consider, from cheap and easy-to-use platforms to those with more advanced features - like automated campaigns, custom landing pages and tools that gather valuable marketing data about your customers.

How can I choose the best email marketing service?

Here's a list of considerations to think about when it comes to your ideal email marketing service:

  • Features. Given the high level of competition on the market, these vary a lot. Basic features include how easy it is to add an email sign up, while more complex features can include the ability to integrate with your email service with other marketing platforms, such as Salesforce, Gmail or WordPress. Some providers will even help you to migrate your existing email marketing service over to them.
  • Functionality. Depending on your needs, you may want access to a wide selection of ready-made templates. On the other hand, you may prefer to utilise a platform with a great drag-and-drop builder.
  • Price. Most email marketing platforms offer a range of tiered plans and free trial periods. Providers will typically peg a rate based on the number of subscribers on your list. As you continue to add subscribers to your list, the price will go up. So, it's important to plan your budget to account for business expansion.
  • Customer Support. The support you're able to access can vary depending on the plan you've chosen with a provider. Ideally, you'd want round-the-clock live chat access, phone and email support. Many providers go the extra mile in terms of professional training services that can be accessed with a few clicks or via video support.
