Before we look at the best email marketing tools, let us know why we need email marketing.

Why do we need email marketing?

Email marketing offers the simplest way of establishing a connection or relationship with customers, prospects, and leads. Here the customers can be both existing and, past customers, and prospects are your potential customer who might have showed interest in your product or services. A lead can be considered as a potential prospect who is yet to get any information or idea about your products or services.
According to studies, few years ago, more than 34% of the entire population of the world, which is roughly 2.5 billion people were using email services. But according to recent studies, half of the world’s population, that is 50% of the entire world’s population use email services. This translates to a whopping 3.9 billion users worldwide. And this number is just going to grow in the years to come. And among the billions of emails sent, a major part of mails are business emails. In short, access to email is more than that of any other marketing method. Therefore, leaving out email from your list of marketing techniques is one of the biggest mistake you can make as an online campaigner.
As mentioned earlier, email is one of the very few marketing tactics where you connect with the audience personally. If you consider PPC, the audience after seeing your ad will see it just as a random ad. But when you send mail to their inbox, might also sit along with the mails from that individual’s friends or family. But to make it feel personal, the message you include in your mail must be personalized, rather than making the receiver feel as a recipient of some bulk messaging campaign. This kind of personalization will consume lots of time when done manually. But this can be done in the matter few clicks when you choose an bulk email marketing tool.

Advantages of email marketing over Other marketing channels


1. Highly cost effective and economical

One of the biggest advantages of email marketing has to be its cost-effectiveness, making it one of the most economical options out there. You can reach a large audience by spending not even half of what you would have to spend with other marketing channels. Well, let us focus more on the effectiveness of this type of marketing in the section. But for the money that you spend, you reach a very large number of people if you choose the right best bulk email service provider.  

2. More effective than other marketing channels

Since sending an email is the most personal form of marketing, the effectiveness of email marketing has grown significantly. The acquisition rate is very high compared to other marketing channels like social media and others. According to studies for every dollar you spend on email marketing, you can expect an average return of $42. This stat itself holds the mirror to the effectiveness of email marketing. But this will not be the same when you consider other marketing channels. Because, some methods will require you to spend a huge amount of money without any guarantee of customer acquisition.

3. Effectiveness is measurable

One of the greatest things about PPCs is that you get complete analytics of all user behaviours. Just like that with an email marketing tool, you can track the users that have opened your mail, the details of the links that were clicked, and more. You get a clear idea about what to do next, how much to spend and if your business really needs email marketing.

4. Easy to reach wide range of audience

Email marketing has one great advantage as a large number of people use their phone more often than using their computers. Mobile devices are something that almost everyone owns and your target audience does not have to be only the business people on their computers. Most of the businesses have non-PC users as their customers and email is the best way to reach these users. According to IBM, more than 49% of emails that are opened, are opened on mobile phones.

5. Old but reliable method

Email marketing has stood the test of time. It has existed right from the beginning and was of one of the earliest methods that were used in online marketing. Even before other concepts that are very popular and highly used, were introduced, email marketing has proved its worth time and again and has also proved to be one of the most reliable ways of online marketing. The reason we call email marketing reliable is, other paid marketing channels might make you waste a huge amount of money, if you invest in them without expertise. But that’s not the case with email marketing. You just have to invest in the right tool. 
Below, we have defined some of the important terms that you will come across in the following sections.

What is SMTP?

SMTP stands for Simple Mail Transfer Protocol. SMTP is a set of community guideline or protocols that allow emailing software to transfer an electronic mail over the internet. In short SMTP is a protocol for sending emails between servers. 

What is External SMTP?

External SMTP is where you send mails from some other IP, instead of sending from you ESP.

What is ESP?

ESP stands for Email Service Provider. ESP is any company or firm that offers email services. 
To make the task of choosing the right tool easier, below are our picks for best email marketing companies.

The most basic package is priced at $11.89/mo. for subscribers ranging from 0-600. And you can send unlimited emails with every premium package. If your subscribers range from 2501-3500, then you can choose the plan that is priced at $37.39/mo., which is the costliest among the listed plans.

ActiveCampaign has impressed us a lot with its best-in-class automation features. In addition to being powered by highly sophisticated auto-responders, ActiveCampaign also allows the automation of all your subscriber list and all your contacts. And to help you build next level connection with your customers or prospects, ActiveCampaign offers customer message feature where you can send targeted and customized messages to the inbox of your website visitors.

When it comes to pricing, it is worth mentioning that ActiveCampaign is not the best option for small businesses.

With ActiveCampaign, you no longer will have to worry about your emails being not delivered to your customers or prospects. With some other email marketing tools, there are chances of your mail being landed into spam folder. But the mails sent using ActiveCampaign end up in the main inbox on almost all email services like Gmail, Yahoo and more. 
And you can choose from up to 40 highly responsive and modern templates that are highly customizable.

8. ConvertKit

ConvertKit is a high-end email marketing that is best suited for professional bloggers and large-scale businesses. ConvertKit is loaded with advanced feature that make it one of the best email marekting tools in the market, but its high price tag make it out of the reach for small businesses and startups and choosing ConvertKit when you have higher email marketing only makes sense. ConvertKit helps you create beautiful landing pages even if you do not have any website. And their best-in-segment support team compliments the price tag at which ConvertKit plans are priced at. 

ConvertKit Highlights

• Specially meant to be used for large scale businesses 
• Loaded with class-leading features
• Lets users create landing page without having website
• Not quite suitable for small email marketing campaigns due to high pricing
ConvertKit Pricing
Free plan: Available
Premium: Priced start at $29/mo.
Supports up to 1000 subcribers
Premium Support
(Prices go on increasing as the number of subcribers increases.)
As mentioned earlier, ConvertKit is for the ones with a limited budget as their most basic plan is priced at $29/mo and this is not all the recommended option for beginners but if you run an established business or with a higher budget, you can choose ConvertKit without any second thoughts. But if you look at the brighter side, ConvertKit offers a free plan too and this free plan despite coming with a restricted number of subscribers, comes loaded with long list of features. And with the $29 plan, you can manage upto 1000 subcribers and the price tag goes higher as the number of subcribers increases. 
One thing that we are not so fan of ConvertKit is the number of the email templates on offer, that is just 3. And moreover, these are text-based and you cannot include any visual content or dynamic content, a feature that is on offer in cheaper tools. But ConvertKit high when it comes to ease-of-use as most of the features is very easy to use and do not require much technical knowledge. 


Just like many other tools, even email marketing tools come with their own unique feature, distinct feature sets, and prices ranging between different scales. You can choose the lower-priced tools if you are running a small-sized business or if you own a startup. But there are some tools like Benchmark Email that are priced relatively low yet offer high value for money with incredible features. And the higher-end tools are extremely robust and powerful, with the support for a higher number of subscribers. So this is our list of best email marketing software that you can choose and but it all comes down to you to decide which one is the best for you.
