In short: no — http://kb.mailchimp.com/lists/signup-forms/the-double-opt-in-process

Our signup forms require the double opt-in process, so there’s not a way to turn off or otherwise disable the Opt-In Confirmation Email. If you’d like more control over your opt-in process, you can use a 3rd party integration like Wufoo’s or host your own forms and use the MailChimp API to pass subscriber information back to your list.

Ah, there it is — subscribe is an array (weird!). You’ll have to check if($submission['subscribe'][0]=='Yes'), and probably wrap that with some isset if you get php warnings (when it’s not there).

Also, if you’re not planning on sending it, don’t map it. It’ll still be part of the $submission for your hook.

My guess is you’re not mapping the ’email’ field correctly – note the case in the “post form” section, and thus there is no email in the “post service” section because you have it looking for ‘Email’.

What does the form post section of the debug email show? Usually unchecked fields aren’t part of the submission, so your negative would never get triggered, and the default $use_submission is true.

You’d probably want to check for yes and return $use…, otherwise return false.

And if you have multiple services you’d want to wrap that in a check for the right $sid.

Hmm…can you post the (sanitized) debug email?

resolving; looks like a double-post with https://wordpress.org/support/topic/submission-to-mail-chimp-problems-1

Use the input name rather than id, so in the example you just posted ‘src’ should be “email-717” and ‘3rd’ should be “EMAIL”.

If that doesn’t work might also need the ‘submit’ value of “Subscribe” too.

Re: the “1” still appearing, is fine – that’s just the array index if the mapping entry, not the ‘val’ key.

“Array” just means it’s a list of values, like the rows of a spreadsheet – the stuff on the left are keys/indexes (i.e. columns).

You’ve still got a couple mistakes:
[val] => 1 <– means you’ve incorrectly checked the checkbox “is value”, which means it’s going to send whatever you’re entered in the src column *as a value*, which you can see in the “post (submission)” array. So uncheck this
[lbl] => The email address
[src] => Enter your email. <– should be Email, the same as the key of the array in the “post (form)” array that you want to send
[3rd] => mce-EMAIL <– this is what mailchimp will see the mapped value under; is this the correct field name they expect?
