To explore this you need to recognise some technical terms such as Split delivery and Dual delivery options. Utilising dual delivery option, incoming mails at the first go, hits the primary mail server which would be directed to the relevant email inbox and then the message would be governed to the secondary mail server which would be dropped in the secondary mail inbox. However, in split delivery, the incoming mail is either governed to the primary or the secondary mail server. This amenity makes efficient work while migrating from any other mail server to Google.

The hybrid plan allows you to bring into service the 2 step authentication which secures the system. You can take advantage of DKIM, as well as configure SPF(Sender Policy Framework) and DMARC(Domain-based Message Authentication, Reporting and Conformance) to get rid of spoofing, phishing, thereby making qualitative deliverability. In addition, you can take advantage of the SSL.
