A client contacted me earlier today regarding not being able to send a Mailchimp email campaign. When he went to send his email marketing email he received the following message:
Mailchimp’s abuse prevention system, Omnivore, has identified some issues with the addresses on your Newsletter that have never been sent to through our system.
Omnivore has indicated that these addresses may cause high abuse complaints or bounce rates, and could contain spamtrap addresses. These are serious issues when it comes to email marketing and delivery. The issues with these addresses will need to be resolved before the list can be sent to.
Upon clicking the resolve button next to the error as above, the following warning was received:
Before you can send to your Example Newsletter list, the addresses that have never been sent to through our system will have to be reconfirmed.
Clicking the Reconfirm button below will temporarily remove these addresses from the list and allow you to send this campaign to any existing subscribers.
You may also contact our compliance team at firstname.lastname@example.org for further insight into what may be causing this detection.
This client had exported the subscriber list from a different email marketing service and had imported the list into Mailchimp. For good reason, Mailchimp is more stringent when it comes to preventing the potential of spam messages being sent from Mailchimp clients. With the reconfirmation process as above, Mailchimp wasn’t blocking the client from sending but was rather noting that any email addresses unknown by Mailchimp would need to be reconfirmed before Mailchimp would send to the unconfirmed email addresses.
