We’re trying to create an automation in Airtable that sends an email from Gmail.
Is there a way to hyperlink text with a URL that’s generated by a formula field?
Basically each email that sends out will contain a unique URL that’s hyperlinked.
Welcome to the community, @Chachie_Pabalan!
Unfortunately, this is not possible in Airtable. 
I would recommend emailing support@airtable.com to ask them to please support this feature. All of my Airtable consulting clients are in desperate need of this, too.
The workaround for all of us is to use a professional automation platform like Integromat for all of automation needs.
(Note that I am a professional Airtable consultant and a Registered Integromat Partner, and the Integromat link contains my personal referral code.
