SpamRate
SpamRate
SpamRate is an email deliverability testing platform for teams that send newsletters, transactional messages, and marketing campaigns. Users send a test message to a set of seed mailboxes at Gmail, Outlook, Yahoo, and Zoho, and SpamRate reports where each copy was placed, separating the inbox from spam and from tabs such as Promotions. Every test also runs technical checks on the sending domain, covering SPF, DKIM, DMARC, MX, PTR, BIMI, MTA-STS, and DANE records, together with domain and IP blacklist lookups and an analysis of message content and authentication headers. The results are combined into a spam rate score alongside the specific issues that lowered it, and every test is stored so changes over time stay visible. Scheduled monitors repeat the tests and send alerts when placement or authentication changes. A WordPress plugin brings the same checks into the WordPress admin, and a set of DNS and domain diagnostic tools is available without an account.Starting Price: $19.99/month -
