Why Choosing The Best Email Marketing Service is Important?

Email marketing is one of the most cost-effective marketing strategy for small businesses. Among other digital marketing strategies, email marketing has the highest ROI, with a whooping average of $38 profit per $1 spent (1). In fact, the Direct Marketing Association says that, email marketing on average sees a 4,300% return on investment (ROI) for businesses in the United States (that’s $43 for every $1 spent on marketing!)

This is because email marketing is easy to manage, relatively cheap, gives you full control, and allows you to establish a direct contact with your customers. Not convinced on email marketing? See these reasons why building an email list is so important today.

Getting such a Return On Investment is largely attributed to how effective your emails actually are. And this has a lot to do with the software you use.

It’s fundamental to understand that a lot of your success with email marketing depends entirely on the email marketing software you choose because they are responsible for making sure that your emails actually get delivered. According to email tool tester, 14.2-16% of emails sent in 2020 never reach the inbox. This number varies with the marketing software being used, telling you how important it is to choose right.

If you aren’t careful, you will end up paying a lot more money for fewer marketing features and terrible email deliverability rates (which causes you to lose even more money).

What to Look for in a Good Email Marketing Tool?

Before jumping in to pick an Email service provider, here are 7 things you must look for in an email marketing software.

Vast Amount Of Email Templates

Really, no serious minded entrepreneur has the time to sit down and build a customized email from scratch. This makes it very important to choose a software that has a lot of templates that can serve different email formats. From promotions to newsletters, there must be a list of mind-blowing templates to choose from. Beyond this, the templates must have features like personalization and dynamic content to make your subscribers feel appreciated and important.

Easy To Use But Powerful Email Builder

You might want to send out these emails yourself, without hiring an extra hand. Therefore, you need a software that is very easy to use, with simple drag and drop features like CTA’s, text, images, etc.

Mobile Friendly

Frankly speaking, you are in for a huge loss if your email templates are only desktop optimized.  As at 2018, 46% of all emails were opened using a mobile phone while desktop opens was estimated at 18%. In fact, at least 30% of professionals check their emails on their mobile phones 2. This shows you how important it is for your email to be mobile optimized and this depends on choosing the right software.

Practical Monthly Limits

As a growing business, you will want an email software with room for growth. Therefore, you should go for one that has more sends per month than you need. You might also want to go for a software that has unlimited offer so that when your business booms, you will avoid the hassle to switching to a different email marketing software.

Good Reporting Metrics

Email marketing is one of the most easy to monitor marketing mediums out there. If your marketing software does not provide reports with click through rates, subscribed and unsubscribe rates, open rates, spam reports, etc. Then it is not the right one for you.

Integrations And Plugins (Add-ins)

Getting an email marketing tool that can easily work with other software or can add extensions for better features is a very important part of choosing the best ESP for your business.

High Deliverability Rate

Most importantly, a good email service provider ensures that your email campaigns are actually delivered and do not end up in the spam folder.

Bonus Tip: Improve Your Email Deliverability

All the email newsletter tools that we have shared in this article have great email deliverability rates.

However there are few things you can do to make sure that your marketing emails always get delivered.

1. Use a Professional Email Address

Email platforms like Gmail, Outlook, and others have algorithms that look for spammy behavior. One of them is the sender email address.

As a business, it’s important that you use a professional business email address (like yourname@yourcompany.com) and not a generic hotmail or gmail address.

This will help make sure that your email deliverability rate is higher than industry average.

2. Send Targeted Emails based on Interests

It’s very important that you personalize your emails based on user segments. Email marketing software like Constant Contact allows you to easily group your subscribers into segments such as most active, not-active, interested in specific topics, custom segments, etc.

This will help your email marketing campaigns have the highest open rate and click through rate which is a big factor in future email deliverability.
