Email retention laws in the United States require businesses to keep copies of emails for many years. There are federal laws that apply to all businesses and organizations, data retention laws for specific industries, and a swathe of email retention laws in the United States at the individual state level. Ensuring compliance with all the appropriate email retention laws in the United States is essential. Non-compliance can prove incredibly costly. Multi-million-dollar fines await any organization found to have breached federal, industry, or state regulations.

Email archiving is absolutely necessary as a result of these federal, state and industry email retention laws. Retention periods vary depending on the regulations that govern your industry sector. Email retention laws require all organizations to quickly execute a legal hold on archived email and provide data in the case of litigation.

All electronic documents must be retained by U.S organizations, which extends to email, in case the information is required by the courts. eDiscovery requests often require large volumes of data to be provided for use in lawsuits and the failure to provide the data can land an organization in serious trouble. Failure to present the requested email can result in hefty fines, sanctions and reputational damage.

For decades, U.S organizations have been required to store documents. Document retention laws are included in numerous legislative acts such as the Civil Rights Act of 1964, the Executive Order 11246 of 1965, the Freedom of Information Act of 1967, the Occupational Safety and Health Act of 1970, and the Reform and Control Act of 1986 to name but a few; however, just over a decade ago, data retention laws in the United States were updated to expand the definition of documents to include electronic communications such as emails and email attachments.

What is the Best Way to Store Old Emails?

Storing emails for a few years is not likely to require masses of storage for a small business with a couple of members of staff. However, the more employees an organization has, the greater the need for extensive resources just to store emails. The average size of a business email may only be 10KB, but multiply that by 123 – the average number of emails sent and received each day by an average business user in 2016 (Radicati email statistics report 2015-2019), and by 365 days in each year, and by the number of years that those emails need to be stored, and the storage requirements become considerable.

If any emails ever need to be accessed, it is essential that any email archive or backup can be searched. In the case of standard backups, that is likely to be an incredibly time consuming process. Backups are not designed to be searched. Finding the right backup alone can be almost impossible, let along finding all emails sent to, or received from, a specific company or individual. Backups have their uses, but they are not suitable for businesses for email retention purposes.

For that, an email archive is required. Email archives contain structured email data that can easily be searched. If ever an eDiscovery order is received, finding all email correspondence is a quick and easy task. Since many email archives are cloud based, messages are deduplicated, and files are compressed, they also do not require huge storage resources. Emails are stored in the cloud, with the space provided by the service provider.

Increasing Dependence on Email

  • Number of emails sent and received daily in 2020: 306.4 billion (Radicati)
  • Amount of business-critical data residing in emails: 60 percent (IDC)

With the rise of remote working, the reliance on business email has grown. More than ever users are treating their inbox as an archive to find documents or information. Email is a centralized store of sensitive data. Consequently, companies use email as a form of information retention, referring back to old emails to find vital information.
