What is the Mailchimp Omnivore warning?
The MailChimp Omnivore warning is a message MailChimp sends to users when an email list is full of risky email addresses.
MailChimp won’t send your email campaign to your subscribers until you clean your list to meet Omnivore’s standards.
Omnivore is like MailChimp’s filter. It uses an artificial intelligence (AI) system that automatically scans every email list you upload to the MailChimp system.
In 2008, MailChimp debuted Omnivore and fine-tunes the algorithm regularly based on feedback and AI.
Omnivore looks for email addresses that might trigger complaints, high bounce rates, or blacklisting.
If your email addresses list has a high percentage of hard bounces, it will trigger an Omnivore warning.
You can see the MailChimp Omnivore warning via email or within the MailChimp SaaS. Once you receive a warning you’ll have to take action.
You can use an email verification service like Emailinspector to overcome the omnivore warning.
Emailinspector will help you detect which addresses are likely to bounce back and generate complaints.
Why Is Mailchimp Omnivore Necessary?
MailChimp doesn’t run Omnivore to be the villain.
Mailchimp Omnivore is a tool to protect Mailchimp’s reputation as well as yours!
Spammer reputation is bad news for both of you. Internet Service Providers (ISP) can block email systems for sending too much spam.
Mailchimp uses the Omnivore service for vetting email lists. This way Mailchimp avoids being a vehicle for spam.
Spam has negative effects across Mailchimp’s total client base because they use shared servers.
This translates to if one client has poor deliverability and gets flagged as spam, the sender reputation of Mailchimp, as an email service provider, is threatened, so their other clients may see a drop in their email effectiveness.
Mailchimp Omnivore’s role is to protect Mailchimp’s entire client base.
This copying mechanism can be an obstacle for new or existing Mailchimp users if the data in their email send lists isn’t good enough.
How Does Mailchimp Omnivore Work?
Mailchimp Omnivore reviews email send lists when you send an email campaign for the first time.
Either when you import new email addresses or via a sign-up form or app.
If an email list ‘pass the test’ the first time you import it, if this list is getting old and you aren’t cleaning the data, it may fail to pass the Omnivore test later on.
When you get an Omnivore warning, your Mailchimp account won’t remove or change your data in your list automatically.
However, Mailchimp Omnivore will put on hold on your lists until you resolve the issues identified by Omnivore.
You can continue your email campaign with your other email lists.
What Is Mailchimp Omnivore Warning?
Mailchimp Omnivore warning is a warning when your email addresses list is full of invalid, and inactive email addresses.
Mailchimp Omnivore scans and analyzes your freshly created email list for spam traps, hard bounce, and abuse complaint addresses.
If your list passes a certain threshold (one that Mailchimp does not reveal), Mailchimp will suspend your email list activity.
Mailchimp will notify you to remove the offending list, perform some cleanup and try to kick start your email campaign again.
But keep in mind, if your account is flagged three times in six months, Mailchimp will close your account once and for all.
The reason that Mailchimp is so aggressive, is because Mailchimp needs to protect its IP reputation, and spammy accounts will harm that reputation.
How to prevent Mailchimp Omnivore Warning?
All your email list need is hygiene. Taking care of it can keep you miles away from omnivore horror.
The simplest and most effective way to remove the warning is to use an email validation service to validate your email list.
1. Use Double Opt-Ins
Use double opt-in for new subscribers to your email list.
Double opt-in is when a new subscriber signs up to your newsletter, you send them a verification email.
Therefore, your new subscriber’s opt-ins will not be complete until they have clicked the verification link.
This is the proven only cost-effective and efficient method to build a ‘clean’ subscriber list.
Besides, you should also send these verification emails and follow-ups as quickly as possible.
Subscribers tend to forget about your value proposition and brand if you wait too long to send an email.
2. Avoid Generic Email Addresses
Role-based emails are associated with a specific role of a business or company.
Role-based emails are not managed by a single person; instead, Role-based emails have different managers in a single department.
For example, if an email list contains role-based email addresses, it makes a high bounce rate.
If your email list has a high number of role-based email addresses, Mailchimp considers it as unclean. Omnivore has a very low tolerance for role-based email addresses.
MailChimp’s Omnivore system won’t stop you from uploading role-based email addresses, but MailChimp’s Omnivore system will hold it against you.
For example, role-based emails are addresses such as [email protected] [email protected] [email protected], and so on.
If your email list isn’t passing Omnivore, try removing some role-based emails that can help you get your list unflagged.
Go to Excel. Use CTRL + F to find emails with role-based prefixes such as support, admin, contact, privacy, no-reply, etc.
MailChimp provides a list of role-based prefixes so you can search and remove them.
3. Use An Email Validation Service
An email validation service is a remedy for the Omnivore warning problem.
An email validation service cleans your email list immaculately.
An email validation service uses advanced tools like risk validator, spam traps removal, syntax checker, duplication checker, and MTA validation.
These tools save you from Mailchimp omnivore warning before you upload your list to Mailchimp.
An email validation service is an ideal solution for the Omnivore warning problem. Moreover, it will help you increase your domain reputation in the long run.
If you receive an Omnivore warning, you might be tempted to use your not scrubbed email list. Don’t send emails to your email addresses list to check the bounce rate. We don’t recommend it.
Your domain reputation will be damaged and your IP can be sent to the blacklist soon.
