Gmail Options

1. Forwarder: set up a forwarder so emails are sent on to the relevant Gmail account.

• You will be able to receive (but not sent) mail from @yourdomain.com addresses
• You will only be able to send mail from your existing Gmail account. 
• This is easiest approach but has the fewest benefits.
• Good for supporting addresses you want routed to your main inbox.

2. Mail Import: Set up a mail account on the web server to run @yourdomain.com addresses then use Gmail to pull in this mail into your inbox.

• You will be able to receive and send mail from @yourdomain.com addresses
• Because Gmail is pulling in mail from another Inbox there is a lag between a mail being sent and it arriving in your inbox.
• Requires a bit more set up but a good middle ground between functionality and cost. 

3. Use Gmail as your Mailserver: Make Gmail your primary mailserver for @yourdomain.com addresses.

• Makes best use Gmail integration with zero lag time, spam filtering and deliverability.
• Requires a GSuite account (additional costs).
