How to Choose an Email Marketing Platform

Email marketing is one of the fastest-growing trends on the planet, and it’s no surprise. Last year, the number of email users clocked in at 3.9 billion, and that number is projected to rise to 4.3 billion within a couple of years. Anyone can see email as the marketing goldmine that it is, but it takes a smart marketer to take advantage of this opportunity to reach their target audience, leads, and customers faster, more efficiently, and more effectively than ever before. Whether you are running a small business or a large-scale operation, leveraging the right free business tools is critical.

The trouble is that when it comes to email marketing software, there are enough choices to keep your head spinning indefinitely. And there is a boatload of features that you can get from each of the various services. Regardless of the size of your company’s email needs, which industry, and who your target audience is, there are a few features that you just can’t (or shouldn’t) do without. Check out these 3 necessary email marketing features.

Integration

Manual data input and actions are so 2010. Today’s digital society runs at breakneck speed, and that means your marketing campaigns need to run even faster just to stay ahead of the competition. This is why integration is so important. You need to make sure your email marketing platform can converse easily, seamlessly, and automatically with your customer relationship management software (CRM). Whether managing a paid or free mailing services solution, the platform should sync with other tools effortlessly.

You obviously wouldn’t have an office where team members weren’t able to communicate with one another about projects, assignments, and resources. In the same vein, you need to ensure that all of your “team members,” e.g., CRM, free email systems, analytics, and any other business management tools you use, can all communicate effortlessly with one another at all times.

Automation

Next up on your shopping list for top email marketing platform features is automation, and here’s why. People are uber busy these days. Nobody wants to wait around for a response, and nobody will wait around to be sold to. When a lead takes the initial clickbait, shows interest in a product, and takes the first step into the sales funnel, a market has to work fast if they want to gain that lead’s business. Tools like a free email signature generator or pre-built workflows are invaluable for this purpose.

But you’ve got hundreds of other tasks on your to-do list and (hopefully) thousands of leads to nurture. How is any marketing team supposed to juggle all of that simultaneously without missing a beat? Automation, baby. Automation means you never miss the opportunity to nurture the lead. The right free business system can automatically send out the right message at precisely the right moment and with exactly the right content for gently nudging the lead along to the next stage. From aggregated customer responses to a well-timed discount code, the best automated free company emails can help you close the deal like nobody’s business.

Responsive Designs and Layouts

It’s no surprise that so many marketers are tailoring their campaigns to fit with the mobile trend. Mobile is quickly becoming the king of content consumption. Today 4 out of 5 Americans do their shopping online, 60% of consumers use their mobile devices to do online research, and most relevant to our conversation, close to 50% of email users open those messages on their mobile devices. And best of all, free email tools often support responsive design to optimize mobile compatibility.

Bottom line, if you want consumers to relate to your product or services, you had better be mobile-friendly. Of course, your email marketing platform needs to accommodate this ever-growing need. Check that your emails look good on the various mobile devices out there, your images load properly, layout isn’t cut off or reduced, and elements are not misplaced when being viewed on smartphones or tablets.

Email Marketing Software Pricing: What to Expect

Like all things, email marketing platforms come in a range of pricing options. There are basic plans and premium ones that will come with a wider range of features and services. For businesses looking to maximize their budget, there are also options for free mailing services or trial accounts. You can find a lite plan from Constant Contact that lets you send 10 emails to your contacts and provides basic eCommerce tools for just $12 a month. Some platforms even allow you to create a free business email solution, ideal for startups or small ventures.

For those seeking budget-friendly options, many platforms offer free email systems for new users, including pre-made templates to help you get started. Whether you're looking for premium features or tools to design professional campaigns, don’t overlook options like free newsletter templates, which are both economical and effective.

Omnisend, for example, has a free plan that includes 250 contacts, 500 emails per month, more than 250 email templates and great reporting tools. Or you can opt for a company like Hubspot to get free email signature generator tools to complement your campaigns. An email signature generator free of charge can be a small but impactful addition to your outreach efforts.

Email Marketing Software: The Game Changer You’ve Been Waiting For

It really just depends on your budget and what you want to get out of your email marketing service. The best rule of thumb is to find a platform that has a decent amount of features to fit your needs while still working within the price range you can comfortably afford. Options like free professional email accounts or free company email setups can provide value to small businesses without straining their budgets. Additionally, tools like free newsletter templates can simplify the design process for marketers.

Email marketing is a big priority, and marketing experts the world over will tell you that a good platform is worth investing in. Whether it’s about leveraging automation or taking advantage of free email systems, every business can benefit from using the right tools. So bear that in mind when making your calculations.
