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 before selecting a capability.

Call SandBase capabilities

Use the capability identifiers below as discovery hints, not MCP tool names. Find the matching endpoint with sandbase_discover(q: "<provider and capability>"); use its returned name in sandbase_inspect(name: "<returned name>"). Read inputSchema, pricing, and execute_as, then call sandbase_run using execute_as.arguments.name and schema-defined arguments. If a run_id is returned, poll sandbase_run_get(run_id: "<returned run_id>") within the task budget until completed or failed; report pending or failed runs without resubmitting them automatically.

Capability identifiers

• 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. Resolve each selected capability with sandbase_discover, then inspect the returned name with sandbase_inspect to confirm the schema and pricing.
3. Follow execute_as with sandbase_run; collect async results with sandbase_run_get as described above.
4. Synthesize findings into a clear, evidence-backed answer.
5. Cite sources, note evidence gaps, and separate observations from interpretations.

Guidelines

• Always call sandbase_inspect 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.
