New subscribers not being added to mailchimp list

When people submit their email addresses my Mailchimp list is not getting updated. I have recently installed Gravity forms and the add-on so it is not a new issue, it has never worked.

I've trawled through the support forum and have checked that the versions of Wordpress and Gravity Forms are all the latest, tested theme and plugins, and checked my API key.

I'm new to Mailchimp so don't know if any of my settings there may interfere with Gravity forms but my list is a pretty simple email sign-up.

So it finally worked, just after a long delay of a few hours. Is this the standard timeframe for communication with Mailchimp? As a subscriber it would seem a bit weird to get a confirmation email a few hours after subscribing. Up to an hour maybe but 5 hours later, not really. I think you should warn people about this somewhere in your documentation as I think expectations in this day and age are for a more instant transaction.

But other than this no complaints, it is working just as advertised and updated my Mailchimp mailing list. If there are problems in the future then I will use the logging plugin.

Thank you for your quick response.

I am having the same issue, but time does not fix the problem. The registrations show up as entries on Wordpress, the confirmation e-mail is being sent immediately from MailChimp, but the names never show up on the MailChim list.

What could be the challenge and how do I fix it. A generic recommendation to contact MailChimp is just passing the buck and this is an integration problem that both sides should know about.

Thanks!
