_Emails form the backbone of business communication_. If the organization faces a disaster or a cyber-attack, business continuity largely depends on [email continuity](/content/email-continuity). An email failover service can provide a solution independent from the primary email system and _ensures that the crucial communication systems are operational during a crisis_.

### Types Of Email Failover Services

An **email failover service** constitutes one of the critical components of an organization’s robust and affordable [disaster recovery plan](https://www.networkworld.com/article/3411457/what-is-disaster-recovery-how-to-ensure-business-continuity.html). They ensure that the employees can access their mailboxes during the primary email system’s failure. They also provide correspondence history when the system gets restored, doubling as a [business continuity email](/content/email-continuity/business-email-continuity) service. There are two types of email failover services

#### MX Backup

The MX [email backup service](/content/email-continuity/email-backup-service) stores the incoming emails and delivers them to the user when the primary email system is restored. However, _it does not allow the exchange of emails during the outage_. Its functions include

- Prevention of email bounce backs
- Prevention of loss of emails
- Functioning automatically
- Deploying **email security** measures for filtering out spam

#### Email Continuity

The [email continuity definition](/content/email-continuity/email-continuity-definition) says that it is a backup email system that allows users to _communicate using their primary email addresses even when there is an outage_. It has the following features

- Prevention of loss of emails
- Prevention of email bounce backs
- Allowing users to send and receive emails in case the primary email service isn’t working due to an outage
- Deploying email security measures for filtering out spam and **phishing emails**

_Email failover solutions are crucial to maintaining business continuity during an unplanned outage_. They can also be useful during maintenance or when the enterprise decides to migrate its emails to a new system to **prevent any loss** of emails.
