I've been building a Machform for sign-up applications, and my client has just dropped the bomb on me that the applicant must now receive an email after completing my Machform to verify their email address to double-opt in to a bulk mail service. This is to allow them to bulk mail communications to all the applicants at once (not spam them with newsletters).
Is there any bulk mail integrations I can add, like Mailchimp?
As a workaround, if our bulk mailer gives us an opt-in form, can I embed it into my Machform?
Or am I stuck with just redirecting the applicant to the bulk mailer's signup form and having them fill out another form repeating some contact info and force me to manage the applican't's info across 2 separate databases?
