Or maybe you’re a seasoned pro and are looking to switch to something new. Either way, I’ve got the best online email marketing tools covered. So, let’s get started…

What is Email Marketing Automation?

Email marketing automation refers to the process of automating email marketing. 

An automated campaign consists of a series of marketing emails that are sent automatically to subscribers based on their actions.

The purpose of email marketing is to create email messages that reach the right people at the right time without you having to work every time.

It allows businesses to target people based on factors such as previous sales, behavior, and preferences.

Email marketing is not like email blasts or broadcasts as they offer the same level of personalization that individual emails do.

There are quite a number of email marketing automation systems available in the market today.

 3/5 – Average

Drag & Drop Editor:
Mobile-Friendly Editor: 
Yes, browser

Ease of Use

Here’s a brief summary of our testers’ experience with ConvertKit: “ConvertKit’s user experience is very simplistic, maybe even too bare-bones. You miss out on some modern features like a drag and drop editor tool or a more comprehensive selection of templates, but you can get the job done fast. Also, the clean look and feel aren’t that confusing for beginners.”

You can build your email list in three ways: add individual contacts, upload emails in bulk from a CSV file, or import your email contacts from another service. Even though there isn’t an option to copy-paste your data, you can easily create a CSV file to bypass this inconvenience. ConvertKit only supports one list of contacts, and you can organize them by using tags.

Building your email is where things get a bit clunky. ConvertKit doesn’t have a modern drag and drop tool you can use, and the only options are plain text and custom HTML code. There’s also a confusing process for selecting a template, and there are only three options. However, we like that the plain text editor is robust and not cluttered with endless possibilities that can confuse beginners. You can still access several editing options by highlighting a line of text.

ConvertKit email editor

The next step takes you to the preview area, where you can see the full message and double-check if it’s ready to go. You then have the option to send the email immediately or schedule it to a later date.

Mobile Editor

ConvertKit doesn’t have a dedicated mobile application. However, their email editor and dashboard are easy to access from the mobile browser with full functionality.


ConvertKit’s feature list is quite typical for a modern email marketing service. They greatly emphasize supporting your growth and even have a cleverly crafted course for building and launching your email marketing campaigns.

ConvertKit lets you send out an unlimited number of emails to your contacts. The other main features are email automation options, personalized content, sign-up form builder, tag-based customer segmentation, and 70+ integrations with various 3rd party applications.

Their customer support is available over live chat during business hours. However, you can create an email ticket to contact support outside of this time. You get upgraded support features with the paid plans, namely Premium and Priority support. ConvertKit also has a wide array of useful marketing articles and a knowledge base that you can use for further information about the service or email marketing in general.

Pricing & Plans

ConvertKit offers both free and paid plans. The paid plans are subscriber-based, and they also provide you with a free migration option if you need to move your data from another email marketing service.

ConvertKit pricing plans

The cheapest paid plan starts at $9/month (annual payment) with 300 contacts.

Yes and no

Ease of Use

A brief summary of what our testers thought of GetResponse: “The whole process from start to finish feels smooth, is user-friendly, and you have a ton of options along the way. However, the experience would be even better with a built-in image editor.”

You can add your contacts easily through the quick-action buttons from the dashboard. You can choose to upload your contacts individually or import them from a file. Depending on your contact list’s size, the importing may take a couple of seconds up to a few hours.

Building your email is relatively straightforward, and you can pick a pre-designed template, start from a blank template, or insert your HTML code in the editor. Working with a template gives you access to drag and drop tools and the building blocks toolbar. We especially enjoyed the block’s name display when hovering over an inserted building block. You can also preview your created emails in the desktop or mobile view making sure the content looks great on all devices.

GetResponse email editor

GetResponse also gives you access to thousands of free stock photos and an integrated Shutterstock gallery. However, the latter doesn’t come free, but you can purchase the desired image after previewing it in the editor. Unfortunately, they lack an internal image editor, so when you upload your image, make sure you’ve already edited it.

Once you create your email, you are directed to the summary page. Here you can name your campaign, write the subject line, and add your email recipients. Most of these options open a popup window and don’t redirect you to a different page, except when you want to redo the editing phase.

Mobile Editor

GetResponse has a mobile application that you can use to access data, create emails, and manage your contacts. However, the email editor in the app is disappointing. The customization options are minimal, and you can only create text-based messages (minus some emotions).


GetResponse focuses heavily on webinars and eCommerce sites. In fact, you get tools for both with even the starter plan. Of course, that doesn’t mean that this service isn’t working with other businesses – quite the opposite.

Since the pricing model is based on the subscriber count, you can send out an unlimited number of emails to your list. The other main features are a drag and drop email design tool, mobile-friendly emails, dynamic content based on customer segmentation, and automated email options with blog digests.

GetResponse’s customer support is available 24/7 over the live chat and email, which is reassuring, especially if you’re new to email marketing. Once you opt for a custom plan, you also get the additional phone support, Slack channel option, and a dedicated support person.

Pricing & Plans

GetResponse’s pricing model is based on the number of contacts you have on your list. You can get the best prices with a 2-year commitment.

GetResponse Pricing Plans

The cheapest plan starts at $10.50/month with 1,000 contacts ($0.0105/contact).

GetResponse doesn’t have a refund policy with their paid plans, but you can try out their service for 30-days. The trial version doesn’t require your credit card details, either.

 MailerLite (

The MailerLite website.

The free plan lets you have up to 1,000 subscribers, and there’s a $15 per month option that includes up to 2,500 subscribers.

MailerLite is a good option if…

All in all, MailerLite is one of the best and most well-rounded options available.

It provides plenty of help creating your emails, managing your list, and automating your campaigns, while keeping the cost low. There are also email marketing webinars to educate you on some aspects of the trade.

Why Does Email Automation Matter?

Email automation matters because it offers better results. Here are five reasons why you should consider email marketing automation:

Create Segmented Mailing Lists

Email automation allows businesses to create segmented mailing lists based on CRM data and subscriber activities.

Effective segmentation allows marketers to send out relevant marketing messages to their customers and potential clients. 

Automation lets brands understand what clients are interested in. Segmented campaigns have 14.3 percent higher open rates and 100.9 percent higher CTRs than traditional campaigns.

Improve Your Conversion Rate

Email marketing is very effective because about 60 percent of customers still prefer emails as a method of contact. It can prove to be a great nurturing tool if used right.

Automated emails generate 110 percent higher click rates than broadcast emails. Plus, sending a series of automated emails offers 13 percent more revenue than sending a single email.

Companies can choose a variety of campaigns from special offers to birthday wishes. The latter can boost conversion by up to 60 percent. You can’t always have a person sending special birthday wishes to your clients, especially if you have thousands of clients.

You can feed this information into a software that can send your automated email message on the given date.

Improve Engagement

Email automation allows marketers to send out timely, personalized, and appropriate messages to their subscribers. This helps to improve engagement. 

Businesses spend a lot of time and money to improve engagement since engaged customers are more likely to convert

On top of that, they are also more loyal and can help bring new buyers to a business.

Automation tools provide marketers with data that can help them identify links or assets within their campaigns that get favorable responses.

Marketers can use this information to create emails that generate curiosity and keep readers engaged by building positive brand impressions, reducing the number of bounces and subscribes.

Increase Efficiency and Revenue

Automation makes the job of sending emails less tiring and more efficient while also improving the bottom line. It allows marketers to automate boring and repetitive tasks, which helps save effort and time. 

Some of the activities they can handle include storing customer data, tracking customers, determining interest level, re-establishing contact, and calculating ROI.

This information helps improve revenue by adding personalization fields to the email such as name, company name, location, etc. 

Customization has been proven to be effective in increasing revenue. It improves open rates by up to 26 percent and can boost loyalty as well as personalized emails lead to 600 percent increase in transaction rate. 


When it comes to email marketing, there are a lot of platforms you can choose from. In fact, more than one hundred platforms are available online. Given these numbers, it becomes hard to decide which platform is the best among the rest. Now, I’m not saying that there aren’t differences between each one of them. It’s just that choosing the right platform for your business isn’t an easy thing to do.

It is a well-known fact that email marketing is one of the most effective digital marketing methods that generates the highest ROI. Thus, a well-executed online email marketing campaign will allow your business to see good performance. If you want to start sending email campaigns, then you should use the best email marketing platform.
