If you prefer to use MailChimp to send your email marketing campaign, you may know that Omnivore, the abuse-prevention program, will make it challenging to achieve 100% deliverability.

Below, we will highlight what Omnivore warning is and how it works, types of warnings and what you can do if you receive such a warning. Also, we recommend that you follow the guideline below to find out how to prevent it.

MailChimp Omnivore Warning

What is it?

MailChimp uses this program as a filter to check and prevent suspicious activity from every email list uploaded by you onto the system. Omnivore has been created with artificial intelligence to scan for bounce rates, spam traps such as overuse of keywords, malicious email addresses, and blacklisting.

If your list contains a high percentage of those spam triggers, you will receive an Omnivore warning. In this case, you simply cannot ignore it as it will not go away until you fix it. If you do not follow MailChimp guidelines, you will no longer be able to send your campaign to that particular list.

How Does it Work?

Omnivore was engineered in 2008 with algorithms that decide the level of risk that each email list has. If the algorithms decide that the percentage is high, MailChimp will not deliver your email campaign. One of the most significant disadvantages is the fact that it will not tell you which email addresses are perceived as high-risk. Therefore, you have to figure out where the problem lies. You have to fix it quickly if you want your campaign to be sent out.

Why Is Omnivore a Necessity?

It is essential to highlight that this program has not been created to be a burden. In fact, it has been engineered to help improve your sender reputation. As mentioned earlier in this article, having a bad sender reputation can be damaging to your business. If you send too many emails that are redeemed as spam, Internet Service Providers will ban you from ever sending an email again.

How Does It Look Like?

MailChimp will send this warning as a message to your Inbox whenever the email list is considered a high-risk.

You will be able to view the warning via email and you also have the option to view it within the MailChimp SaaS. You must always check for such a warning every time you create a campaign as it won’t send if you do not fix it.

What Triggers an Omnivore Warning?

There are three significant reasons why you can be classified as high-risk. The first can be either inactive email addresses, questionable email addresses, and spam traps.

Inactive Email Addresses

A list that has been created from invalid email addresses means that you will receive a higher bounce rate. A stale list means that you have not targeted them in a long period of time. Therefore, your sender reputation is likely to be damaged and you are also prone to trigger the spam filters.

Having inactive email addresses can be dangerous. People are unforeseeable, they will leave jobs and companies, making their email address invalid. Moreover, some inactive users will simply mark your campaign as spam as they are no longer interested in your content.

Keeping up to date with consumers in your mailing  list is essential if you want to avoid an Omnivore warning. Hard work is expected from you by MailChimp.

Questionable Email Addresses

Unfamiliar email addresses are common. Some people will put their job description rather than their names, some will misspell, and some will simply not insert the right email address. Each time you put a new email address into the system, Omnivore will scan to check them.

If Omnivore has detected a large threshold of such email addresses, you will receive a warning.

Spam Traps

You must ensure that your list does not have such traps if you want to avoid receiving a warning. The algorithms will scan for emails that are used by ISPs and spam organizations that often trigger complaints. It would be difficult to check for such email addresses by yourself as they do not necessarily look strange or questionable. Hence, it would be nearly impossible to decide for yourself whether it is a spam trap or an email address belonging to a real person.

How to Prevent Omnivore Warnings?

Fortunately, there are things that you can do to ensure that your list is 100% clean and you have high email deliverability.

Double opt-ins

We recommend that you apply a double opt-in process for those that want to sign up for your mailing list. This option will allow people to sign up and receive an email straight away and the sign-up process is completed only when they click a verification link in the email. This process is increasingly becoming popular because it’s fool-proof.

If you want to create an immaculate list, you must ensure that people have verified their email addresses. As well as, you have to make sure that every single recipient has agreed to receive your campaigns.

Check Email Addresses

Being safe is a good idea if you want to avoid such warnings at all costs. The algorithms will specifically check for role-based addresses and perceive them as a tell-tale sign of a bad list. The reason for this is because they usually have high bounce rates. The threshold exceeds Omnivore standards. In fact, in the majority of cases, numerous people receive such warnings due to the sizeable role-based email addresses.

Third-party Lists

First of all, you must remember that it is illegal to purchase a list from third-parties. However, some people will go around it and still use such a service. If you want to avoid an Omnivore warning at all times, you should create the list by yourself. Third parties collect stale addresses that are full of spam traps. If the system detects that you have used such a list, you will get rejected.
