No guarantee. We do not guarantee inbox placement, deliverability, or any specific outcome. Filtering decisions are made by recipient mail providers.
Data captured. When you send an email to a test address, we store the raw message (headers and body) so we can generate a permanent results page.
Retention. You may configure retention and deletion later. Until then, treat test messages as potentially stored. Do not send sensitive personal data.
Acceptable use. Do not use this service to send spam, malware, phishing, or unlawful content. Abuse may be blocked.
