And last but not least, we will take a look at Mailvio, one of the most powerful ESPs available to digital marketers. 

But first, here’s a quick breakdown of the four (4) different types of email service providers.

Types of Email Service Providers

Email Service Providers vary based on the services they offer, niche, and general use. 

  • SMTP Relay Provider. These ESPs use an SMTP Relay each time an email is sent. They are particularly useful in eliminating spam. This is done by the means of authentication, licensing, and their own networks. 
  • Dedicated Email Service Provider. These email service providers have high reputations with email clients and are effective in the fight against spam. They use their own infrastructures only for the sending of emails. They make it easy to manage emails and deliver bulk campaigns to many servers such as PHP, ASP.NET, or Java.
  • Web-Based Email Service Provider. These platforms are mostly used for internal business communications and are very cost-effective. A good example of a web-based esp is Outlook. 
  • Email Autoresponders. Autoresponders are designed specifically for digital marketing needs. They have robust features that allow users to communicate effectively with subscribers. They have many high-level features such as automated workflows and detailed reporting systems.

What Makes A Good Email Service Provider

Making any buy for your business requires detailed inspection and comparisons to get the best deal. When choosing an ESP you need to consider some specific aspects as listed below:

Ability To Customize And Personalize Emails

To stay relevant and competitive you need to have a brand development strategy as well as the ability to relate to your customers. 

In email marketing, this is facilitated by customizable email templates and personalization features. 

A good ESP will include these capabilities so that you can firmly establish your brand and gain your subscriber’s trust. 

Storage Space

The number of emails in your inbox also determines how much storage space you have for messages. 

More complex emails need more room than simple text ones. 

Not only does sent items not store all your emails, but it’s also possible that other folders like inbox and archive message. 


mobile friendly autoresponder

Since over 49% of all emails are opened on mobile phones, it is essential that your email service providers are mobile-friendly. 

This will help in user experiences and ensure that all your email content can be delivered as intended.

Great Support

Without great support, you will stumble along your email marketing journey. Support is the backbone of any successful business. If a company overlooks the needs of its customers, it’s likely that it will not provide quality products either. 

Custom Domain

If you have a business, use a custom domain for your email. It will make your company look more professional, and people will trust you more. 

It is easy to remember too! Your ESP should allow you to add a custom domain to your sender’s address. 


affordable autoresponder

Needless to say, your ESP must provide value for money. Take into consideration all you are getting and decide if it’s worth the price. 

Many ESPs charge way more than a fair price for what they offer. Others will remove much-needed features in an attempt to lower the cost. Ideally, you want to use a service that is both affordable and rich in features.

Now, while the above email service providers are great for personal and business use…

A completely different type of ESP is needed when it comes to digital marketing. To achieve worthwhile results, digital marketers need to make use of an email autoresponder. 

Let’s take a closer look at autoresponders and specifically, our very own Mailvio.

Email Autoresponders

An autoresponder is a tool that allows you to send marketing campaigns automatically to a mailing list based on specific rules at defined intervals.

They allow you to establish profitable and long-term relationships with customers through branded email interactions. Increasing brand awareness and customer loyalty. 

One of the main reasons for using an autoresponder is that they help to improve deliverability rates. The more of your emails that get delivered, the better your results will be. 

You’ll have higher open rates, more engagements, and better conversion. Combine that with the ability to personalize each email interaction with your subscribers…

And you have a winning system that marketers cannot find with just any email service provider. 

And most autoresponders provide detailed reporting systems so you can analyze your campaign’s performance. 

Email automation drives up to a 14.5% increase in sales on average and 80% of users see an increase in their leads. 

A while back we interviewed some top marketers at various stages of their business and asked what they think makes a perfect autoresponder. 

And we got the same three (3) answers over and over again:

  1. It should have great deliverability 
  2. It should have world-class features like Active Campaign does
  3. And most importantly, it should be affordable, especially in the current economic climate.

Based on these answers we went out and created the Perfect Autoresponder – Mailvio
