Deliverability Guide
Anti-spam organizations monitor mail server traffic worldwide to prevent phishing and spam.
On low-cost mass-market hosts, another user on the same shared IP might send unsolicited bulk email, causing the entire IP address to be blacklisted for all hosted sites.
Outdated WordPress plugins or insecure contact forms can be exploited by bots to send automated spam without the website owner knowing.
Sending emails to stale or invalid contact lists triggers spam trap traps, alerting Spamhaus and SpamCop to throttle your sending reputation.
