Top 50 Email Marketing Service Providers & Best ESPs in 2024

When we first built SendView, one of the most requested features was identifying which email marketing platform sent each email. Since then we’ve created rules for over 300 Email Service Providers (ESPs) to pinpoint which tool was behind the marketing emails you receive in your inbox. With so many providers to choose from, shopping for one yourself can feel like a daunting task that leaves you with all sorts of questions.

  • Which email marketing services are other brands using?
  • How many of them are using each service?
  • Which email marketing tools are the most popular?
  • Who are the up and coming ESPs?
  • Which are the best free email tools?
  • Are there email service providers for businesses like mine?

When you combine datasets from SendView and ESP Finder, we’re looking at hundreds of thousands of emails sent by thousands of different brands. Which means that we can rank the most frequently used ESPs fairly reliably. So whether you’re looking for a new email marketing platform or just curious about how they stack up, here’s where things stand based on our data set in 2024.

What are the best email marketing services?

What’s unique about email marketing companies is that many are tailored to very specific industries or verticals. They do this because the email needs of an independent publisher are very, very different than that of a B2B software company, even though both heavily rely on email marketing. As a result, the tools, features, and functionality of each marketing platform are often built specifically for the unique email needs of the exact users they’re hoping to serve. For example:

  • Klaviyo is built specifically for retail businesses
  • ConvertKit is built specifically for creators
  • Loops is built specifically for SaaS companies
  • Pardot is built specifically for B2B sales

In other words, there are many services that would be considered best email marketing platforms because each company is the best for a specific type of user. For the email platforms listed below, we’ve added a little bit of context to better understand the strengths (automations, deliverability, etc.), user types (b2b, retail, etc.), and pricing for each one.

What are the best free email marketing services?

When trying to nail down the best free ESPs it’s important to think about what your goals and constraints are. For example, if you plan to send a lot of emails to a small list, a free tier that doesn’t limit your email volume is probably best. On the flip side, if you send few emails to a large list, a free tier that doesn’t limit your contacts is probably the way to go. Let’s look at a few good choices based on those two criteria.

Which ESPs have free tiers with email limits?

  • Sender has one of the highest limits at 15,000 emails / month
  • ConstantContact limits free users to send 100 emails before they need to pay.
  • Brevo allows free users to send 300 emails a day.

Which ESPs have free tiers with subscriber limits?

  • Sender also has one of the highest limits at 2,500 subscribers
  • MailChimp’s free tier allows up to 2,000 subscribers.
  • Klaviyo offers a free tier with up to 250 subscribers.
  • Omnisend allows up to 250 subscribers on their free tier.
  • ConvertKit’s limit is 300 subscribers for free plans.
  • MailerLite’s limit is 1,000 subscribers on their free tier.
  • GetResponse has a free tier that includes 500 subscribers.

Which ESPs have free tiers with both email and subscriber limits?

  • EmailOctopus allows you to store up to 2,500 contacts and send up to 10,000 emails per month on their free plan.

Is there such thing as a free email marketing service?

There really is no such thing as a truly free ESP. Instead, there are paid ESPs that offer free tiers for their service. The good news is that email is such a good way to generate sales and revenue that once you get a few hundred subscribers it should be easy to generate enough cash to afford a paid plan. So instead of shopping for an ESP solely because of their free tier, look for an ESP that has all the features you need at a price you feel comfortable with and offers a free plan to get you started.
