They confirmed that the emails were blocked due to a DMARC issue. It's a setting some senders use to prevent others from faking emails from them.

SpamHero is one of the best tools in the market I have ever used. This is really cost-effective tool and really easy to manage.

It's this incredible customer support and the effectiveness of the product that makes me want to tell everyone about SpamHero.

I love that this is a "set it and forget it" product. I can literally go months without visiting the site.

It just does what it is supposed to do which is block spam. If you do need help - customer support is top notch.

For the cost it does a great job filtering most of the spam.
