A snapshot of the email service provider landscape
While there are clear market share leaders in the email service provider (ESP) and marketing automation platform (MAP) industry, brands still have a long list to choose from. How long? Respondents to Litmus’ 2020 State of Email survey mentioned more than 230 ESPs when asked which platforms they use to send marketing emails.
Twelve companies were used by at least 1% of respondents. Three years ago, there were 20 used by at least 1%—which goes to show how the ESP landscape is constantly changing with mergers, acquisitions, and new players.
In order of popularity among our respondents, the top 12 ESP brands are:
- Salesforce (includes Salesforce Marketing Cloud, Salesforce Pardot, and Salesforce Core): used by 18.1% of respondents to Litmus’ State of Email survey
- Mailchimp (includes Mandrill): 11.1%
- Adobe (includes Marketo, Adobe Campaign, Magento, and Adobe Sign): 7.6%
- Oracle (includes Oracle Responsys, Oracle Eloqua, Bronto, NetSuite, Siebel, and Dyn): 6.2%
- HubSpot: 5%
- Campaign Monitor (includes Emma and Delivra): 3.5%
- Constant Contact: 3%
- Twilio (includes SendGrid): 2.8%
- Acoustic (formerly Watson Campaign Automation/Silverpop): 2.8%
- ActiveCampaign: 1.5%
- Iterable: 1.2%
- Act-On: 1%

Please note that the list above is based on user market share, not user value market share.
That means the comparative market shares listed do not necessarily reflect the comparative size of these ESPs as companies. Additionally, these listings don’t consider past changes in market share, the strength of future offerings, your unique business and team requirements, or a myriad of other factors that may be critical to comparing or selecting an ESP. For those reasons and others, these listings shouldn’t be considered as an endorsement or recommendation of one ESP over another.
Litmus works alongside any email service provider and is proudly ESP-agnostic.

The ESP industry’s long tail
While those ESPs control the vast majority of market share, there’s a healthy long tail of ESPs in the marketplace as well. Some are up-and-comers; some specialize in serving organizations in a particular industry vertical; some offer special functionality; some offer email as part of a much larger service. It’s a rich and diverse landscape.
In some cases, it’s also interesting which vendors our respondents described as ESPs. It’s evidence that the definition of an ESP is changing.
