 Email Marketing Automation Service

What Makes an Email Marketing Automation Software Option a Great One?

An email marketing platform can be considered a great one if it provides a reliable set of automation features. This means that your email platform should be able to offer you the ability to create or implement ready-made email sequences. These workflows will handle the customer engagement process without your intervention. Based on the action subscribers take after reading each email in the sequence, the tool will automatically send them a series of personalized emails. 

Complex reporting and testing features are also important. To know how your email campaigns are working, you need accurate data on how many people have read your emails, clicked on your links, unsubscribed, etc. Being able to perform A/B split testing or to test your emails’ deliverability is a key factor in crafting successful email campaigns.

The number of contacts you can use the platform for is another criterion that can make the difference between a good platform and a great one. The best services allow you to use their tools with a large or unlimited number of contacts for a reasonable price. 

Why Is Choosing the Best Email Marketing Automation Software Important? 

The best email marketing automation software for your email campaigns shouldn’t be a choice, but a must-have. There are multiple reasons why any company regardless of its size should be using such a tool. The most significant one is the fact that email marketing is still an efficient method to promote your business. 

Nowadays, people are more connected than ever and while social media or Google advertising can help you get some of the leads you aim for, these probably shouldn’t be the only strategies you focus on. People pay close attention to what’s happening in their inbox, most check their emails on a daily basis. Therefore, if you write well-targeted emails that manage to get past spam filters and deliver them on time, periodically, you’ve got good chances to engage your contacts and convert them into buyers. You can achieve this more easily if you automate your campaign using an email marketing platform. 

This tool will help you save time, optimize your content, deliver your message at the perfect time, and keep track of your open rates. Email marketing is still the main marketing strategy for approximately 80% of small businesses. This says enough about its effectiveness. 

Email Marketing Automation Features

What Features Should I Look for in an Email Marketing Automation Tool?

  • Automation is the core feature you should be looking for when your main aim is to put your email campaigns on autopilot. Through automation, you can implement different workflows that will help you save time and walk your leads through the conversion funnel easier based on their actions. 

  • Segmentation features are important because they allow you to divide your contacts list based on their specific behavior, website activity, previous purchases, demographics etc. in order to craft targeted emails that are more likely to lead to a purchase. 

  • Integration is one of the main features to be looking for when purchasing an email marketing automation platform. The software you decide to use should allow you to easily connect it to other marketing tools, social platforms, CRM systems or WordPress to facilitate multi-channel marketing activities.

  • Reporting capabilities are a good starting point when you have to decide which email marketing software to work with. Platforms that provide in-depth reports and strong analytics are great, especially for advanced marketers who need to get plenty of insights to be able to optimize their email campaigns. 

  • An intuitive dashboard might be for many marketers another must-have feature. Although you need to be at least a bit tech-savvy to start automating your email campaigns, this doesn’t mean you’ve got a lot of time to learn how to use an intricate system. The best way to automate your campaigns stress-free is with an intuitive platform that streamlines your user experience. 

  • A/B testing and spam detection tools are other useful features to watch out for when you want to buy email marketing software. These tools will allow you to test different emails to see which ones are more engaging and make sure they’re not blocked by spam filters. 

  • Customer service also plays an important role when it comes to buying an email marketing tool. While most services in this niche offer a vast array of educational and training resources to help you out, it’s important to know that there’s also a customer department you can contact. The best platforms offer multiple contact options including live chat, email, and phone support.
