I have my list of emails first being run through an email verification filter to minimize bounces. I even go through periodically and export all of my old verifieds to make sure they’re still valid before sending to them. I know that PHP list has a first pass filter that detects if an email is valid or not. I’m assuming it just goes through the RFC standards of what an email address is supposed to look like. A couple of questions:
- Is there a way to add parameters to that filter: Say, “if firstname.lastname@example.org” mark as invalid or blacklist
- I imported a couple of lists as CSV that were formatted as "email@example.com" with the quotes in the CSV. But one of the files I’m importing continues to mark all emails as invalid, even though they follow the same format and on the preview import screen appear without quotes. Anyone seen this yet?
