The GTM intelligence gap

Your data is trapped

Getting answers from your outbound data means logging in, filtering, and reformatting. By the time you have the answer, the window has closed.

Signals without context

You're paying for intent data. But your reps still send generic outreach because they don't know what to say or why right now is the right moment.

No feedback loop

Which sequences are converting? Which reps have messaging that lands? That answer lives in your data, but no one has time to dig it out.

Ask. Get answers. Act.

01 Connect

Link Letterdrop to Claude Code, ChatGPT, or any MCP-compatible AI agent. Takes under 5 minutes.

02 Ask in plain language

"What accounts should my BDR reach out to this week?" "Which sequences have the worst reply rate?" Your AI agent queries Letterdrop directly and gets a structured answer.

03 Review and act

Your AI agent returns specific, contextual recommendations - not a dashboard to navigate. You review, approve, and act.

What GTM teams use it for

Outbound Performance Reporting

Ask your AI agent for a full reply rate breakdown by rep, sequence, and persona. Get the answer in plain language, not a pivot table.

Account Prioritization

Surface the accounts worth reaching out to this week - based on recency, context, and buying signals - ranked and ready for your team to review.

Contact Intelligence

Know when a past customer or contact has joined a new company. Your AI agent flags it so you can reach out in the window when they have fresh budget and goodwill.

Closed-Lost Re-engagement

Your AI agent surfaces deals that have hit their natural reconsideration window and tells you who to reach out to and why now makes sense.

Message Performance Analysis

See when your reply rates are trending down before it quietly costs you pipeline. Catch the pattern at 6 weeks, not 6 months.
