What Can I Do to Improve Email Deliverability?
Enhancing email deliverability is crucial to ensure that your messages reach the recipients' inboxes and avoid being flagged as spam. One effective approach is to implement SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records for your domain. These authentication mechanisms help in verifying the legitimacy of your emails and building trust with email service providers.
You can generate SPF and DKIM records using online tools like SPF Record Generator and DKIM Core Key Generator. Once you have obtained the records, add them to your domain's DNS settings to authenticate your email sending domain.

Incorporating HTML content in your emails allows for more visually appealing and engaging communication with your recipients. When crafting HTML emails using PHPMailer, remember to set the isHTML property to true to indicate that the email content is in HTML format.

You can enable debugging mode in PHPMailer by setting the SMTPDebug property to 2 for verbose output. This will log detailed information about the SMTP transaction, allowing you to identify any errors or anomalies in the email sending process. Here is how you can enable debugging in PHPMailer:
