Although the omnivore system set up by MailChimp is reliable and effective, however, the matrix is mistaken by signaling legitimate accounts as being suspicious. You are explained here how to prevent your email campaigns from being interrupted and your hanging MailChimp account.

MailChimp omnivore, what is it?

It is through the famous US mail service provider MailChimp that each year passes an incalculable number of emails. To prevent abuse that is often encountered in emailing, the platform has created a baptized omnivore system, responsible for ensuring that the rules are well respected by the sender.

If, for example, your company sends emails for a campaign, omnivore will check both the sender and addresses of recipients on a list that you have newly created and imported. Omnivore will analyze potential spam traps, hardbounces and complaints for spam. Basically, this system will control if all the good practices of emailing are well put in place before sending, in order to protect the IP reputation of its users.

What happens if I get an Omnivore warning?

Receive a warning on the part of Omnivore does not mean that your MailChimp account will necessarily be suspended, you still have margin.

The Omnivore Warning is here to warn you that the emails of your campaign can not be sent to the selected list, so the campaign is temporarily blocked. This warning therefore concerns a particular list, which means that you can still, despite the warning, send emails to other lists that have been validated after omnivorous analysis.

In the case where your campaign would be suspended, you will need to delete the relevant list, cleaning from it taking into account the problems reported by MailChimp. Once your list is verified, you can try to send your emails again.

Be careful, although a warning does not result in the suspension of your MailChimp account, three warnings received within six months will result in a definitive closure of your account. Hence, the importance of applying the good practices of emailing, but also to consider omnivore returns in the event of a warning.

What to do to avoid triggering an omnivore warning?

The most important thing is to always check your lists before sending your campaign. It is enough for an @ too much, a misplaced sign, of a forgotten space, so that the address is invalid. Small, sometimes subtle mistakes that can, if they are too numerous, block your campaign and severely start your reputation as sender.

Here are the omnivore mailchimp triggers:

  • Hardbounces emails
  • Keyboard typos
  • Bad syntax
  • Disposable emails
  • Emails Roles: admin@, support@, contact@…

With regard to syntax errors (very common), the analysis of your contact list can be done manually in Excel. On the other hand, in order to verify the validity of the addresses as such, you must use specific tools designed for this purpose (like CaptainVerify). These will help you for example to identify hardbounces addresses, role addresses, typing faults, etc., and will always be more reliable and accurate than a manual verification.

we will never say enough: Do not buy and do not rent no contact listings because they are often full of bad addresses and will probably result in a faulty warning if you use them for your campaign. Although this system can give some cold sweats to emailing managers, it is useful and highly beneficial for the company as for the recipients. The first can maintain a good reputation as a sender, while the second will be better protected from the daily pollution that constitutes the massive shipment of emails.
