Emails getting blocked or sent to Spam
Most of my emails are getting blocked, placed in spam, gmail promotions, or showing as unverified sender. Use a few sites that check domains for spam, and here are the issues. Not sure how to fix it. I'm using Outlook 365 and SendGrid to send some automated emails.
Reverse Entries for MX records
WARNING: Found mail servers with inconsistent reverse DNS entries. You should fix them if you are using those servers to send email.
All mail servers should have a reverse DNS (PTR) entry for each IP address (RFC 1912). Missing reverse DNS entries will make many mail servers to reject your e-mails or mark them as SPAM.
All IP's reverse DNS entries should resolve back to IP address (IP → PTR → IP). Many mail servers are configured to reject e-mails from IPs with inconsistent reverse DNS configuration.
Connect to Mail Servers

Check DMARC record
NOTICE: Domain doesn't have DMARC record. DMARC (Domain-based Message Authentication, Reporting & Conformance) helps reducing potential of email-based abuse such as spam and phishing e-mails.
No DMARC Record found
spfmowdays.com Too many included lookups (16
spfmowdays.com A null DNS lookup was found for include (mail.mowdays.com)

All of your DNS records are correct on our end. I see that you did add a DMARC.
Sometimes, on shared hosting where many customers use the same email servers, they get detected as contributing to spam and unnecessarily get blacklisted by a few recipient email servers and RBLs. We do have a system in place that monitors our mailout server IPs for their reputation at RBLs that sends out reports periodically. Our Network Operations team rotates the blocked IPs automatically and that should resolve any blocks our servers may have, given time. We do recommend trying to resend the bounced emails.
Additionally, we have already informed our engineering team regarding this issue and our engineers are working towards a fix on increasing the reputation. I'm afraid we do not have an ETA on this. We appreciate your patience while we resolve this issue.
