Email Service Providers we like

An email service provider (ESP) is a company that offers bulk email software and services. 

An ESP may provide tracking information showing the status of email sent to each member of an address list. ESPs also often provide the ability to segment an address list into interest groups or categories, allowing the user to send targeted information to people who they believe will value the correspondence.

ESPs may have similar basic features and functionality, but vary in volumes, policies, and deliverability, which makes the selection of an appropriate ESP critical to both the success of an email marketing campaign and the cost effectiveness of its implementation.

ESPs policies, also known as terms and conditions (such as an Acceptable Use Policy), are meant to prevent abuse by users in order to ensure that no spam is sent through their systems. This is intended to result in the best possible delivery rates, with no messages blocked as spam. 

An ESP will provide a service which may include the following features:

  • Ability to create templates for sending to contacts and/or the use of templates pre-made
  • A subscriber list, which is uploaded by the user for distributing messages. This may be enhanced with custom fields in order to hold additional information for each subscriber for filtering and targeted messaging purposes
  • A send engine, which allows users to distribute their message to the subscribers
  • Updating of the subscriber list to suppress those requesting to be unsubscribed
  • Statistical reviews of each email sent to measure the success rate of the campaigns
  • Testing of templates for compatibility with email applications
  • Spam testing to gauge the score of the email against known factors that will place the template at risk of being blocked
  • The ability to send both html and plain text formats to improve delivery success rates (known as Multi-Part MIME)
  • The ability to customise dynamically the content of emails that are sent out, to tailor personalised and relevant communications
  • The level of service provided can be according to the above basic features, or the number of subscribers uploaded, or the frequency of use – or any combination of the above criteria.

Some ESPs cooperate with Mailbox Providers, through organizations such as the Messaging Anti-Abuse Working Group, to ensure compliance with legislation and best practices, and get feedback on the messages they send.
