Authenticating your sending domain with DKIM and SPF records is vital for improving email deliverability. This process verifies the legitimacy of your emails, reducing the chances of them being marked as spam.

Monitor your sender reputation regularly. A good reputation ensures higher deliverability rates. Avoid sending spammy or unsolicited emails, as they can harm your reputation and lead to blacklisting.

Use the data you have about your recipients to personalize email content. This increases engagement and reduces the chances of your emails being marked as spam.

Design responsive email templates that render well on different devices. Ensure your emails are visually appealing and easy to read.

Always test your emails before sending them out. Check for rendering issues, broken links, and spelling errors. Use tools like Litmus or Email on Acid for testing.

7. Segment Your Audience

Segment your email list based on user preferences, demographics, or past behavior. This allows for more targeted and relevant emails, increasing engagement.
