Hi all! In an effort to combat some deliverability issues, we are trying to create a brief instructional document for our customers on how to whitelist Marketo to ensure they receive our Customer Success/Marketing communications. I have been looking around the various Marketo doc pages for instructions on this and cannot seem to find anything for this use case, only instructions for whitelisting internally (ex. for test emails from Marketo to our company domain.)
Anyone have any ideas or examples they could share?
