Usage

Your newsletter form template can look something like this:

<form method="post" id="mailchimp">
    {{ csrfInput() }}
    <input type="hidden" name="tags" value="Tag_1,Tag_2">
    <input type="text" name="name">
    <input type="email" name="email">
    <button type="submit">Submit</button>
</form>

The only required field is email, all the rest is optional

use the vanilla js example below:

const form = document.getElementById('#mailchimp')
form.onsubmit = (e) => {
    e.preventDefault();
    fetch('/mailchimp/send', {
        method: 'post',
        body: new FormData(this)
    })
    .then((r) => r.json())
    .then((r) => {
        if (r.success) {
            alert(r.msg)
        } else {
            alert(r.msg)
        }
    })
    .catch((e) => {
        console.error(e);
    });
};

or jquery/ajax...

$('form#mailchimp').submit((e) => {
    e.preventDefault();
    $.post({
        url: '/mailchimp/send',
        data: $(this).serialize(),
        success: (r) => {
            if (r.success) {
                alert(r.msg)
            } else {
                alert(r.msg)
            }
        },
        error: (e) => {
            console.error(e);
        }
    });
});
