If your Sender Score is lower than desired, there are several steps you can take to improve it:
Reduce Complaints: Make it easy for recipients to unsubscribe rather than marking your email as spam. Clearly state the purpose of your email and only send to those who have opted in. Minimize Bounces: Regularly clean your email list to remove invalid addresses. Use double opt-in methods to ensure the validity of email addresses. Avoid Spam Traps: Do not purchase email lists, and be cautious about how you grow your list to ensure all subscribers are genuine. Monitor Blacklists: Regularly check if your sending IP or domain is listed on any blacklists and take steps to get delisted if necessary. Maintain Consistent Volume: Avoid sudden spikes in sending volume, as this can be a red flag for email providers.
