ISPs track your sending behavior to determine future inbox placement.

Major providers require proper authentication to accept your emails.

FAQ
An email deliverability score is a metric that indicates the likelihood of your emails reaching the recipient's inbox. It's based on factors like DNS configuration, authentication protocols (SPF, DKIM, DMARC), and domain reputation.
To improve your score, ensure you have valid SPF, DKIM, and DMARC records configured. Also, monitor your domain's reputation, avoid sending spam, and maintain a clean email list.
A score above 90 is considered excellent. Scores between 80-90 are good but may have room for improvement. Scores below 80 indicate potential issues that could lead to emails landing in spam folders.
