Types of email service providers

Email service providers differ not only in their service, but also usually in the infrastructure used and in their spam control measures. The following types of email service providers provide a first orientation:

  • SMTP relay provider: SMTP relays are used every time an email is sent outside of your own address range, even in private communications. In the case of mass emails or mass mailings, SMTP relays are third-party providers that can exclude spam through authentication, licenses, and their own network. This means that email servers do not classify certain emails originating from that server as spam. Sometimes SMTP relays are used in conjunction with an API, which automatically reads customer data and provides reports[3][4].
  • Dedicated email service provider: Like dedicated servers, dedicated email service providers are designed to use their own infrastructure. The servers are used exclusively for sending emails. The advantage is that dedicated systems can enjoy high status due to their closed infrastructure and can be effective in fighting spam. Dedicated systems usually provide additional features such as records management or email delivery to a variety of server systems, such as PHP, ASP.NET, or Java. Using an API, mass emails can be automated. The technical resources used are for this case on the supplier side.[5]

An interface is normally included, which can be used by all workers in the company. Clients of cloud email services typically use them as software as a service across the enterprise and pay monthly fees. This means that using cloud email services is associated with relatively little effort and a high level of planning.
  • Integrated marketing platform: Some marketing programs and tools offer integrated solutions that allow marketing, web analytics and other functions to send mass emails. These solutions are usually designed for use in large companies. The prices are correspondingly higher, because the functionality is partly very high. Multi-channel marketing, data-driven marketing, and IOT apps can be part of the portfolio.

  • Templates can be created and edited.
  • It offers an infrastructure that works as a sending engine and handles the mass sending of email templates.
  • Opt-outs are automatically updated. The opt-ins are integrated according to the legislation.
  • Metrics such as open rate, delivery rate, or click-through rate are collected and the data is displayed in reports.
  • Tests can be performed to establish whether emails are retrieved from clients and server variants.
  • Various measures are taken for spam control and quality assurance.
  • Different types of MIME are supported. It is feasible to change emails dynamically, for example in the context of target group characteristics or seasonal campaigns.
  • Additionally, there are aspects such as a free trial stage, monthly contracts or various payment options, so that the costs match the client's requirements. Because some ESPs will set a limit on emails, others will bill based on the number of data sets or sending frequencies.

Legal issues

Depending on the country in which the email service providers and their clients are active, they should be observed very different legal conditions and requirements. For the US, the Acceptance Use Policy and the CAN SPAM Act should be mentioned. In Europe, the conditions for mass mailing are specified in Directive 2002/58 / EC (Data protection directive for electronic communications). Email service providers can also participate in other industry initiatives to help combat spam.

Relevance for online marketing

The figures for the sector speak for themselves. Email service providers are still useful and profitable when sending emails to customers in large quantities. The return on investment in email marketing is approximately $ 44 for a $ 1 investment.[8] Emails can have an impact on sales by precisely sending specific purchase incentives for each target group and relevant recommendations to a wide range of recipients. Therefore, the choice of an email service provider can be considered a critical factor.
