I’ve struggled with this on my site too - I don’t want to custom code a solution so I’ve been using Mailchimp but Mailchimp is gross (it keeps people’s emails even if they unsubscribe) SendGrid is cool and allows for much more flexibility with emails like custom variables, I recently rebuilt my email templates with MJML but I really wish there was just an easy service that allowed you to POST to an endpoint, supported double opt in and gave you that level of control. After researching it became clear I was going to have to setup some kind of custom backend for my Gatsby site or use a server less function service and write the code myself.
