These Terms of Service (“Terms”) govern your use of SenderSignal, operated by Info Science Labs Corp (“Company”). By using our service, you agree to these Terms.

1. Service description

SenderSignal is a deliverability and reputation platform for email-sending teams. Depending on your plan, the Service includes:

Reputation Shield: monitoring of domains and sending IPs against blocklists, DNS checks, uptime probes, alerts, reports, and status pages.
Reputation Builder: DNS setup guidance and domain verification for domains you control.
Inbox Boost: domain warmup workflows you configure for domains you control.
Inbox Intelligence: inbox placement testing and deliverability insights.

SenderSignal is a monitoring and deliverability platform. It is not a general-purpose SMTP relay. Warmup and sending features run only when you enable them and only for infrastructure you authorize.

2. Account responsibilities

You must provide accurate registration information.
You are responsible for maintaining the security of your account credentials.
You must not share workspace access with unauthorized parties.
