How to add an auto response to subscribe emails ko

Hello everyone, does anyone know if it is possible to do an automated response to those that subscribe to your e-mail newsletter? This is where I would like to thank them for joining and offer them a % off of their first order for joining. Thank you in advance for helping.

You can do this in two ways:

1st: Using a plugin from shopify store like “WebPanda Contact AutoResponder” which costs 5$ per month.

2nd: You can use the same email platform to respond to emails from the subscribers but you have to have a specific email only for the subscribe content, which you can respond to them and include a discount code in it after you generate from shopify.
