Hello @user88568 ,
If you recently changed the way your emails are authenticated, it can affect your delivery temporarily. The only real way to resolve this is to just continue to send emails, so the safe sender reputation improves over time.
If the customers you’re sending to are part of major corporate or governmental organizations, they’re also likely using an Outlook program. If so, your contacts will likely have to explicitly approve downloading / displaying images in emails. They may even have to copy links and open them manually in their browser. This will vary wildly between their personal Outlook settings, as well as their organization’s IT settings. We have an article regarding common display issues, which includes programs like Outlook blocking images (among other elements) as a default.
If they’re “missing” your emails, they may also need to check if their email program is sorting your emails into other folders / categories (e.g. Gmail's categories). If so, moving your emails into their regular inbox should teach their email program that’s where they should be delivered. Similarly, if they find your email in their junk/spam folder, they can mark it as not spam to teach the email program’s algorithm.
Beyond all this, if you’re wanting more in-depth, specialized insight on your current deliverability, it’d be worth speaking directly with one of our Deliverability agents.
