This is an extract from a conversation with one of our user in regards to this recipe : https://www.workato.com/recipes/45019-emails-to-mailchimp
"Then I started the recipe and expected to add 1.9k contacts, but only 5 were added. Maybe the settings are wrong?"
It turns out that the MailChimp will send an email to the contacts and only if the contact clicks accept in the email, will Mailchimp considers it as a subscribers. The email they will receive will look something like this:
Please Confirm Subscription Yes, subscribe me to this list. If you received this email by mistake, simply delete it. You won't be subscribed if you don't click the confirmation link above.
So if you face the similar situations where the jobs are completed but the contacts are not added, please do note on this situation. If you need any help, do feel free to post a topic on our forum and one of our Workato Experts will get back to you as soon as possible.
I believe this would not happen if the Double opt-in option is set to false in the action part of the recipe. By default it is set to true.
