How do I send a coupon when a customer signs up for my mailing list automatically?

How do I send a coupon when a customer signs up for my mailing list automatically? Square marketing only has an automation to send a welcome email after first purchase. How do I automate an email that gets sent immediately after someone subscribes?

@Juicy  I believe if you go to marketing. And then contact collection you will

be able to turn on an incentivized email sign up. So when people sign up they can receive a $5 off coupon.
