Hi there,
In case that anyone comes across this in the future, whenever I hit such a problem, I usually send an email to the https://www.mail-tester.com/ website.
The Mail Tester site will provide you with a report on how you could increase your email deliverability rate and give you suggestions that you could follow to make some changes.
Best,
Bobby
