Hi, I'm currently setting up a workflow with MailChimp and NeverBounce using callin.io. The goal is to automatically delete or unsubscribe emails that are invalid upon signup, preventing any automations from starting.

So far, it's working, but I'm encountering an issue when using the callin.io filter option. I can only seem to filter emails marked as invalid, but I also need to filter emails categorized as:

Disposable

Catchall

Unknown

However, these options don't appear to be available in the filter settings.

I did consult ChatGPT about this, and it suggested that these options should be available. It's possible the information is outdated, and the current functionality might only support filtering for invalid emails.

Filter help: https://zapier.com/apps/filter/integrations#help

 

The Filter condition will not evaluate to true, as you are comparing an email address value from Mailchimp to a verification result value (e.g., invalid) from NeverBounce.

WRONG: [1. Email] exactly matches [2. Verification Result]

 

RIGHT: (NOTE: without the quotes around the value)
[2. Verification Result] exactly matches “invalid”
OR
[2. Verification Result] exactly matches “disposable”
OR
[2. Verification Result] exactly matches “catchall”
OR
[2. Verification Result] exactly matches “unknown”

My apologies if this is a simple oversight on my part, but I don't appear to have the option to select a verification result:

It's the variable you had already chosen in the callin.io Filter condition; it seems that needs to be the top/left condition instead of [1. Email].

Fantastic! Thanks for confirming that the resolution provided got the callin.io workflow running. This will be a great reference for our Community members facing the same issue.
