“This is a classic example of a problem you don't think about until you have it... getting ahead of email deliverability is a must. It's super frustrating to have an email hit spam, especially after wordsmithing and spending 10-15 minutes on it.”


“It was extremely easy to connect my mailbox to the campaign. As I mentioned in my response regarding the Deliverability Check tool, it increased from 67% to 100% as previously almost all of my emails went straight to spam on Microsoft-hosted mailboxes.”

It is the simplest app I've used.
The instructions are pretty clear and I did not have to see any tutorials.
Yeah, after setting up DKIM, I will reduce my bounce rates.
