  • Email Health Check

    Gmail and Yahoo will enforce new sender authentication policies from February 1, 2024, targeting bulk senders—those emailing over 5,000 recipients daily. To combat spam, they require SPF, DKIM, and DMARC compliance, easy unsubscription options, and a spam complaint rate below 0.3%. Non-compliance may result in emails being marked as spam.

  • Campaign Precheck

    Mailster’s Precheck feature allows you to efficiently assess your campaign’s deliverability. It analyzes subject lines, links, images, and provides a SpamAssassin score. Additionally, it checks authentication methods and your server’s IP against over 50 blocklists, ensuring your emails reach their destination without compromising privacy.
