# Email Validator

Validate email addresses for deliverability, check reputation scores, verify MX records, and assess email-sending safety. Covers deliverability checks, reputation scoring, bounce risk assessment, and bulk validation for outreach campaign preparation. Read [the API map](references/sandbase-api-map.md) before selecting a capability.

## Call SandBase capabilities

For every selected tool, call `sandbase_describe_tool` first and use only arguments in its current input schema. Then call `sandbase_call_tool` with the exact `tool_name`.

## Available Tools

- `strale_email_validate` - `strale_email_deliverability_check` - `strale_email_reputation_score` - `strale_mx_lookup`

## Workflow

1. Understand the user's research question, target, and context. 2. Call `sandbase_describe_tool` for each selected tool to confirm parameter schema. 3. Call `sandbase_call_tool` with the exact tool_name and schema-defined arguments. 4. Synthesize findings into a clear, evidence-backed answer. 5. Cite sources, note evidence gaps, and separate observations from interpretations.

## Guidelines

- Always call `sandbase_describe_tool` before using any capability. - Cite sources and preserve attribution (URLs, usernames, dates, metrics). - Separate factual observations from analysis and recommendations. - If data is unavailable, note the gap and continue with available evidence. - Read-only research only. Never take actions on platforms.
