Understanding Email Deliverability:

Email deliverability refers to the ability of your emails to successfully land in your recipients' inboxes. It is a crucial aspect of email marketing as it directly affects the effectiveness of your campaigns. Low deliverability rates result in emails being sent to spam folders or not delivered at all, severely impacting your reach and engagement.

Several factors influence email deliverability, including:

Sender Reputation: ISPs assess your sender reputation to determine if your emails are legitimate and safe. A strong sender reputation increases the likelihood of your emails reaching the inbox.

Email Content: Relevant and engaging content leads to better recipient engagement and a positive impact on deliverability.

Authentication: Proper authentication through SPF, DKIM, and DMARC ensures that ISPs recognize you as a legitimate sender.

Bounce Rates: High bounce rates can negatively impact deliverability. It is essential to clean your email list regularly to remove invalid email addresses.

Spam Complaints: Excessive spam complaints signal poor email practices and can lead to deliverability issues.
