Heya, I’m monitoring my Activity Logs tab with a focus on ‘Failed to send email’.
I’ve just noticed that a lot of campaigns are showing the following reason for not sending, eg. reason: "To field: ".mike@gmail.com" is invalid"
Is there a way to filter out those invalid emails?
Thanks!

I haven’t used it. Looks like they may help with some automated list cleaning at the delivery level.
Hey Enrico,
Customer.io automatically filters emails that do not meet the RFC 5322 standard.
Customer.io doesn’t filter addresses beyond this standard, with the exception of profiles that return a hard bounce.
You may consider using a dynamic segment to filter addresses that do not return a hard bounce and have an invalid address.
For instance, a segment similar to the following should capture a majority of the failed addresses -
Note: I’ve added an “at least 10 times” condition to this example as you may want to safeguard against profiles that return a failed delivery as a result of malformed liquid in message content, etc…
As Travis is mentioning above the audience can be adjusted with customer segments. I’ve added a filter on the Trigger, not to let anyone further from the very beginning that doesn’t have a correct email. Then the segment itself includes a list of the most common email mis-spellings. This filter out most of the contacts quite ok.
