I tried setting up Google Workspace for the first time

Introduction

Google Workspace comes packaged with various services, and I find it quite convenient for small businesses to implement.
This time, I wanted to test several Google Workspace Admin (administrator) functions, so I tried setting up the initial configuration from scratch myself.

Test Environment

• Google Workspace (initial 14-day free trial)
• Domain (Route53)

Google Workspace Initial Setup

Initial Domain Verification CNAME Record Registration

First, we start with verifying the domain you own.

1. Enter your Domain
2. Add Username
3. Select Domain host
4. Register CNAME record on Domain host (Route53 in this case)
5. Verify CNAME registration

Register MX Records for Mail Server

Next is the setup to enable receiving emails.

1. Press the Proceed with activation button
2. Register MX records on Domain host (Route53 in this case)
3. Verify MX record registration

Something to be careful about here. Since Priority is specified as 1, you need to enter the MX record Value as follows:

1 SMTP.GOOGLE.COM

Register DKIM Records for Reliability

Finally, to increase the Reputation (reliability) of the emails you send and prevent spam filtering, proceed to Set up DKIM.

1. Press the Set up DKIM button
2. Select Domain host
3. Press the Generate key button to generate a key
4. Register TXT record on Domain host (Route53 in this case)
5. Confirm TXT record registration

A tricky point here. The DKIM Value is quite long, and since it exceeds 255 characters, you may get an error when trying to register it as is in Route53 or similar services.
In that case, you need to split the string using double quotation marks "" as follows:

"v=DKIM1;k=rsa;p=MIIBIjANBgkqhkyKW""TSNSkxmSe4dRfWDCxGQ7i9It"

Even if you split and register it using two pairs of "" like this, it will eventually be properly combined and recognized as one full value, so don't worry.

Completion

If you proceed to Gmail now, you should be able to use your Gmail account with your custom Domain set up instead of google.com.

That's it
