Email marketing remains a powerful tool for reaching customers and prospects. When using the Mailjet Send API, it's crucial to follow best practices to ensure optimal email delivery. Here are 16 key best practices to keep in mind.

1. Authenticate Your Emails

Authenticating your emails with SPF, DKIM, and DMARC helps improve deliverability and reduces the chances of your emails being marked as spam. These protocols verify the sender's identity, enhancing trustworthiness.

2. Maintain a Clean List

Regularly clean your email list to remove inactive or bounced email addresses. This improves your sender reputation and reduces the risk of being flagged as a spammer.

3. Personalize Your Messages

Using the Mailjet Send API, you can easily personalize emails with recipient data. Personalized emails are more engaging and less likely to be marked as spam.

4. Segment Your Audience

Segmenting your email list allows you to send more targeted and relevant messages. This increases engagement and reduces unsubscribe rates.

5. Optimize Your Subject Lines

Craft subject lines that are clear, concise, and compelling. Avoid spammy words and phrases that might trigger spam filters.

6. Test Your Emails

Always send test emails to yourself or colleagues before sending to your entire list. This helps identify any potential issues with formatting, links, or images.

7. Monitor Your Sender Reputation

Regularly check your sender reputation using tools like SenderScore. A high sender reputation improves email deliverability.

8. Use Double Opt-In

Implementing a double opt-in process for new subscribers helps ensure that your email list consists of engaged and interested recipients.

9. Respect Unsubscribe Requests

Promptly remove recipients from your list when they unsubscribe. This is not only a legal requirement but also helps maintain a positive sender reputation.

10. Avoid Spam Trigger Words

Certain words and phrases, like "free," "win," or "guarantee," can trigger spam filters. Avoid using these in your subject lines or email body.
