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

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

What Is Such Warning?

MailChimp uses this program as a filter to check and prevent suspicious activity from every email list uploaded by yourself 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 won’t go away until you fix it. If you don’t follow MailChimp guidelines, you will no longer be able to send your campaign to that particular list.

How Does It Work?

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

Why Is Omnivore a Necessity?

It’s important to highlight that this program hasn’t been created to be a burden. In fact, it has been engineered to help with your sender reputation. As mentioned in the (articol intern), 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 warning every time you send a campaign as it won’t send if you don’t fix it.

What Triggers an Omnivore Warning?

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

Inactive Address

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

Having inactive addresses can be dangerous. People are unforeseeable, people will leave jobs and companies so their address will remain even though they leave. As well as, some inactive users will simply mark your campaign as spam as they’re no longer interested in your content.

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

Questionable Addresses

Unfamiliar addresses are common. Some people will put their job description rather their names, some will misspell, and some will simply not input the right 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 addresses, you will receive a warning.

Spam Traps

You must ensure that your list doesn’t have such traps if you want to avoid getting 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 addresses by yourself as they don’t necessarily look strange or questionable. Hence, it would be nearly impossible to decide for yourself whether it’s a spam trap or a real person.

How Can TheChecker Help Me?

It would be very difficult for you to check every single email address by yourself. This is why you should consider our email verification service.  The innovative algorithms will check for inactive addresses, bad syntax, and addresses that have been marked as spam-traps.

One of the biggest advantages is the fact that your sender reputation will remain undamaged. Thus, you will limit the possibility of getting blocked by Internet Service Providers.

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 to the 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 a truly clean list, you must ensure that people have verified their email address. As well as, you have to make sure that every single recipient has agreed to receive your campaigns.

Check 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 insanely high bounce rates. The threshold exceeds Omnivore standards. In fact, in the majority of cases, numerous people receive such warnings due to the large role-based email addresses.

Third-party Lists

First of all, you must remember that it’s 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’ve used such a list, you will get rejected.
