For SDR teams

More conversations from the same list.

SDRs are measured on conversations and meetings, and dialing numbers that won't connect costs both. Check the list before the session and spend the dials where people pick up.

What they’re trying to do

Sales development reps and the managers who run their calling blocks.

  • Book meetings from live conversations
  • Spend calling blocks on people likely to pick up
  • Keep every prospect in a sequence, even when the phone won't reach them
The problems

What gets in the way.

Calling blocks full of dead air

Voicemail, no answer and wrong numbers eat the block before the first real conversation.

No way to tell numbers apart

The export lists a mobile, a direct dial and a switchboard the same way, so every number gets the same effort.

Bad numbers hide in good lists

A list that looks clean in the CRM can still carry reassigned and disconnected numbers.

Where it fits

In the workflow.

  1. 1

    Build the list

    In your data tool or CRM, as you do today.

  2. 2

    Check it

    Upload the CSV, or have RevOps call the API when contacts are created.

  3. 3

    Dial High chance and Low chance

    Load them into your dialer or call list.

  4. 4

    Sequence Bad data

    Email and LinkedIn, so nobody drops out.

What matters most

The features that help.

One answer per contact

High chance, Low chance or Bad data. Nothing to interpret mid-block.

Name match

Know the number belongs to the person before you ask for them by name.

Works where you work

CSV upload, API, or inside Claude, ChatGPT and Cursor over MCP.

Example

What it looks like in practice.

A morning calling block

  1. 1

    Before the block

    Export the day's list and check it.

  2. 2

    Load the dial list

    Put the High chance and Low chance contacts into the dialer.

  3. 3

    Dial

    Bad data contacts are already in an email and LinkedIn sequence.

Example

What your reps open each morning.

A checked prospect list with an outcome and a next action on every row, ready to hand to a dialer
An example result for an SDR list: every row says whether to dial or to use another channel. Names and numbers are invented.
FAQ

Questions, answered.

Do SDRs need to change how they work?

No. Checking happens before the session. Reps dial the same way, from a list that's already sorted.

Can a manager check lists for the whole team?

Yes. Check the file once and share it, or have RevOps call the API so contacts arrive checked.
