Oct 7, 2021 - By Skirmantas Venckus


Email is the primary communication and marketing channel for most businesses.

Sending out offers, newsletters, and other client-facing communication is primarily done through email marketing platforms and tools. Ensuring that these service providers deliver a great product is just one piece of the puzzle.

Most email marketing services will keep a close eye on their premium IPs and delivery servers. However, significant differences will begin to appear once you start comparing them according to price, features, and user experience.

In this blog post, we will go over several email marketing service providers, their plans, features, benefits, and drawbacks. Additionally, we will carefully consider the needs of both smaller and larger businesses as budget constraints and required features will differ greatly.

Best Email Marketing Services for Small Businesses

Going through absolutely every email marketing platform and analyzing every small difference would take a considerable amount of time. Additionally, for over 90% of cases, such an in-depth overview wouldn’t be as useful as most businesses go for the standard plans. Thus, we decided to pick 5 providers and go over their standard plans.



Well, you know it’s us. We’re an email marketing platform that thinks everyone else is either too expensive or too complicated. Sender gives you everything you need to optimize email campaigns from start to finish, maintain high deliverability, automate workflows, and much more.

Top Email Marketing Services for Free

While most standard plans from email service providers don’t cost a fortune, for some businesses any price is just a tad too high. Luckily, there are plenty of email marketing services that provide their platforms free of charge for a smaller amount of subscribers and, possibly, reduced features.

We decided to compare 3 of the most prominent email marketing platform provider free plans. For those looking for a free email marketing service for ecommerce or any other use case, one of these three will definitely be enough. Additionally, upgrading from free plans will be hassle-free as all of these providers have great standard plans.

While the decision to pick one of these three service providers should be based on highly specific circumstances, businesses in nearly any sector or industry will be able to find the perfect fit-out of the ones outlined above.

Opt-in Email Marketing Services

Ever since GDPR was released, having consumers and customers opt-in to any marketing activity has become a necessity. Any business that works with European citizens is required to uphold GDPR requirements. In practice, every digital business has to have an opt-in feature.

Email marketing is no different. Customers have to be able to both opt-in and opt-out. Sending unsolicited marketing emails can cause a whole host of issues – primarily, legal ones. According to official sources, the fine for sending unsolicited emails or failing to uphold the GDPR laws can land a hefty fine – €20 million or 4% of yearly revenue, whichever is higher!

Clearly, failing to adhere to GDPR can cause significant harm to any company’s financials and reputation. However, some non-EU-based email marketing platform and service providers have no opt-in features. If such a feature doesn’t exist, any email, sent to an EU citizen, could potentially be breaking GDPR laws.

Thus, there are three email marketing service providers that we know for sure have opt-in features – Sender, Omnisend, and Mailerlite. These tools offer ways to collect visitor consent and opt-in contacts using embedded sign-up forms or popups. Thus, if any subscriber is (or potentially will be) from the EU, using the tools outlined above is a necessity.

Enterprise Email Marketing Service Providers

Finally, out of all businesses, the ones with the highest requirements will often be enterprises. Simply picking a provider based on price and basic features is no longer enough. 

As change in enterprises, even agile ones is significantly slower than in smaller businesses, carefully weighing the options is necessary. Once a decision is made, changing the provider quickly is nearly impossible. Thus, we recommend to look out for several features for enterprise businesses:

  • Dedicated account managers. The needs of enterprise-level companies are significantly higher. Any disruption or any other issue needs to be taken care of as quickly as possible. Therefore, finding an email marketing service provider that will give a dedicated account manager should be one of the primary objectives.
  • Dedicated support for migration & onboarding. As movement will be slow and a large number of accounts will have to be migrated (and a lot of people trained), efficient onboarding and migration will be key.
  • Unlimited user seats. One thing that will quickly grind everyone’s gears will be getting disconnected due to too many users. Limited user seats will greatly negatively impact efficiency and overall satisfaction.
  • Full API documentation. Enterprise-level businesses will implement a lot of automation and integrate email marketing platforms into other tools. In-depth documentation will be something that developers need.
  • Unlimited access to automation. Enterprises have no time to fiddle around with limited automation or failures to implement complex workflows.

These are the most important features for any enterprise-level business. Of course, the regular email marketing platform benefits are a nice added bonus. However, they will commonly have dedicated developers that can take care of any features that might be necessary for marketing departments.
