Hi,
After trying out your product for a week, every email practically ends up in the Spam folder. I'm testing it out using a list of contacts based on Gmail, Hotmail, and individually owned domains. After examining the received email's raw data in Claude.ai to analyse it's spam score, the results are very, very bad (scores 41 points to Spam score), 38 of which being because "SPAMHAUS_DBLACK: 38 points - Contains a URL (wemailtrack.com) listed in the Spamhaus DBL blocklist" and 2.5 points for "URIBL_DBL_SPAM: 2.5 points - URL listed in the Spamhaus DBL spam blocklist". FYI Spamhaus is one of the most respected anti-spam organizations, and their DBL specifically targets domains associated with Malware distribution, Phishing attempts, Spam operations and Known botnet command & control servers.
I think you must have very bad IP ranges that have been polluted, but either way we cannot use this service for deliverability. Otherwise 2 tacos because the interface is neat.
