Self-managed email server or Third-party email services?

Should you have a self-managed email server or use a third-party email provider?

This is a very important question to ask yourself, as there are pros and cons to each option, and we are here to discuss those pros and cons. The goal of this article is to provide you with the necessary information to be able to make this decision for your business.

Using a Third-Party Email Provider


  1. Ease of Use: Third-party providers offer user-friendly interfaces and simple setup processes, requiring minimal technical expertise.

  2. Security and Compliance: Reputable providers invest heavily in security and are often compliant with major regulations, reducing the burden on you to manage these aspects.

  3. Deliverability: One of the most significant challenges of managing your email server is maintaining compliant deliverability. Emails sent from self-managed servers can often be flagged as spam by receiving servers due to non-compliant send practices. Third-party help clients navigate the ever-changing landscape of email deliverability requirements, ensuring that your emails reach their intended recipients.

  4. Integrated Features: Many providers offer additional features such as spam filtering, antivirus protection, and productivity tools.

  5. Reduced Maintenance Overhead: The maintenance overhead of managing your own email server can be intimidating. It involves regular software updates, security patches, disk space maintenance, and troubleshooting. All of this requires time and expertise. Third-party providers handle all these aspects, without any effort on your part.


  1. Cost: While convenient, third-party services can become costly, especially as your organization grows and requires more mailboxes.
  2. Less Control: You have limited control over the server settings, data storage practices, and security measures.
  3. Data Privacy Concerns: Hosting sensitive data with a third party can raise privacy concerns, depending on the provider’s policies and data handling practices.
  4. Vendor Lock-in: Migrating to another service can be difficult, especially if you’ve become heavily integrated with a provider’s ecosystem.

Self-managed an Email Server


  1. Full Control: You have complete control over your email infrastructure, including server settings, security measures, and data storage policies.
  2. Customization: You can customize the email server to fit your specific needs, from the user interface to integration with other services.
  3. No Vendor Lock-in: You’re not tied to the terms, conditions, or price changes of a third-party provider.
  4. Cost Efficiency at Scale: For large organizations, self-hosting might be more cost-effective at scale compared to paying per-user fees to a third-party service.


  1. Complex Setup and Maintenance: Requires technical expertise to set up, secure, and maintain. This can be resource-intensive and time-consuming.
  2. Hardware and Infrastructure Costs: You’re responsible for all hardware, software, and infrastructure costs, including maintenance and upgrades.
  3. Security Risks: You bear the full responsibility for securing your email server against spam, malware, and hacking attempts. All of these items can impact your email reputation and sending capabilities.
  4. Spam Management: Dealing with incoming spam and ensuring your outgoing emails are not flagged as spam can be challenging. This involves setting up proper spam filters and maintaining IP reputation, which requires constant attention and tweaking.
  5. Deliverability Issues: Ensuring that your emails reach their intended recipients and don’t end up in spam folders can be challenging, especially when email blacklists or poor server reputation come into play. Proper setup and regular monitoring of sender’s reputation are required to mitigate these issues.

In conclusion, the choice between using a third-party email provider and a self-managed solution should be guided by your organization’s specific needs, technical capacity, and long-term strategic goals. If you are prioritizing Ease of Use, reduced maintenance overhead, and integrated features, and do not want to have to be worried about security and compliance, then you would probably want to consider a 3rd-party provider. However, if you are a larger organization that has the technical ability and resources to manage a self-managed email server and can afford the maintenance overhead, then a self-managed email service might be right for you.
