To avoid email spam folders, send relevant content, use a clear sender name and subject line, and give readers an option to unsubscribe. It’s also essential to regularly clean your mailing list of inactive users. Another thing you can do is follow email authentication protocols like SPF, DKIM, and DMARC to increase email deliverability. Proper email domain configuration will maximize your chances of landing in the right inbox folder. In general, email content should be relevant, personalized, and valuable to subscribers. Make sure that they’re targeted based on subscriber behavior and preferences, and don’t contain any deceptive or misleading information.
