This article will introduce comprehensively introduce you to email archiving, elaborate on it and aid you in locating the best email archiving service to suit your business needs.

Why Archive Emails?

When managing emails, most people refer to two options – saving or deleting them. Archiving email messages has proven superior to those two options, as it manages your emails in a far more efficient format. How? Archiving email messages both saves and deletes them. 

A sender would prefer to delete emails to keep the inbox clean, and ensure everything is read and replied to. A sender who saves emails understands that any email, either read or replied to, could be useful in future. However, archiving removes emails from the inbox, eliminating visual clutter, yet storing them for future use.

Legal Reasons

In most cases, organizations archive due to compliance, which is enforced by legal regulation. Every country has its own regulations on employment, and a significant part of important communication among employers and employees occurs through email. This is particularly important for multinational companies, that have to consider international legislation. 

Email audit and electronic discovery are also legal reasons to archive your emails. If an authority requires access to your email, rejection is not an option, especially during legal investigations. This brings us to another reason – litigation protection during lawsuits, where the court might request an email.

Economical Reasons

By archiving emails you reduce storage and licensing costs. This also aids in internal workflow optimization, where an employee will no longer need to contact the IT department for email recovery. Archiving your emails allows an employee to access the archive itself and retrieve the email, otherwise, the retrieval would take hours or even days.

Archiving emails also supports the protection of company data, since no information exchanged via email will be lost upon deletion. And gives an option to freely migrate to another emailing platform, without losing any content on the previous one.

Technical Reasons

Moving your emails to an archive instantly improves your email server performance by unloading data from the exchange server. Leading to de-duplication and optimized back-up, alongside better management of the PTS files.

On-Premise or Cloud-Based Email Archive?

Traditionally, emails have been archived on-premise, however, cloud-based options are receiving increased popularity. But why might a cloud-based archive be better for most organizations, than an on-premise one?

Aside from the cloud-based option being lower in cost, there are several pros and cons between on-premise and cloud-based email archiving services. 

On-Premise Solution

  • Market Stability: the on-premise email archiving services have been around since 2000. This allowed the market to develop and provide archiving services with better email server integration.
  • Direct Control: as the on-premise archiving solution is available in the house, you have complete control over the archiving process and direct management over the business-critical data. 
  • Stable Payment: aside from the initial investment in the hardware, with the on-premise solutions, you are only required to pay an annual maintenance fee, which at times is even offered freely by the vendors.
  • Administrative Resources: the on-premise solution requires various IT infrastructure and administrative resources to manage and maintain the archive efficiently.
  • Higher Cost: the initial purchase of the archiving hardware is higher. Due to that reason, the initial on-premise email archiving appliances are considered a capital expenditure.
  • Difficult Trial: as the initial implementation takes more finance, time, and effort, testing the solution prior to the purchase is practically impossible.

Cloud-Based Solution

  • Easier Payment: cloud-based services are usually charged on a monthly or yearly basis, which makes budgeting an easier and more convenient process.
  • Simple Deployment: Implementing a cloud-based archive solution is quick and requires little to no effort from your end.
  • Effortless Maintenance: the cloud-based archiving services are maintained, secured, and regulated by the service provider, leaving you without concern for it.
  • Unstable Charges: cloud-based archiving services charge per inbox, which can constantly alter your costs, depending on the human resource changes in your organization.
  • Security Risk: since your cloud-based service might archive your data in another country’s organization, the security of your data will depend on that organization.
  • Limited Customization: few cloud-based archiving services offer add-ons for media content or instant messages, which could be important to some organizations.

It is important to review all of these pros and cons before deciding if an on-premise or cloud-based archiving service is best suitable for your organization. 

First, understand the size of your organization, cloud-based services tend to be more cost-effective for small or medium-sized organizations. Larger organizations, especially ones that handle legal matters, prefer on-premise archiving solutions for a more secure backup of personal data.
