Several factors can lead to lower deliverability rates:
Poor Sender Reputation: If your domain or IP address has a history of sending spam, it can affect your reputation and result in lower deliverability. Content Issues: Emails containing spammy words, excessive use of images, or suspicious links are more likely to be flagged. Inadequate List Management: Sending emails to an outdated or unengaged list can lead to high bounce rates and spam complaints. Lack of Authentication: Failing to set up SPF, DKIM, and DMARC records can make it easier for your emails to be rejected.
