What is MailChimp Omnivore?


MailChimp’s world-leading email marketing service provider owns an AI-based abuse prevention system know as “Omnivore “, which comes into play when you import email lists in the MailChimp account. The Omnivore system checks the email list based on certain parameters, few of them are –

  • Holds invalid and bad emails,
  • Honey spot or spam traps email,
  • Disposable emails,
  • abuse complaint emails,

….and many more parameters which MailChimp will never be going to make public. The only way to import an email list to your MailChimp account is by fixing the Omnivore warning.

How to resolve the Omnivore warning?

“Precaution is the cure”. These lines perfectly fit a person who is dealing with MailChimp Omnivore’s warning.

The foremost thing you need to keep in mind is to never go for the purchased email list. You will not only get your MailChimp account suspended but also end up wasting a lot of money and time. Make sure to always build your list and take proper consent for sending emails. For example, you can put subscriptions form over your website and get their email addresses.

Apart from this, the only and trusted way of resolving the Omnivore is by cleaning your email list before uploading it to your MailChimp account. By cleaning your email list, you will ensure that all bad and invalid emails, bounced emails, honey pot emails and spam emails that could result in Omnivore warning are removed out.

To be precise, cleaning of the email list comprises procedures where each email is triggered out manually and their receiving server sent back a response whether they can receive the trigger or not. These responses are then recorded back and read, based on which a clean email list is provided which comprises all valid emails.

You can then upload the clean email list in your MailChimp account, which will be surely uploaded without any warning issues.
