Keep bad emails out of your CRM

Verify prospects before reps reach out. Every contact gets a result and a reason, so your CRM only holds addresses worth emailing.

The problem

Why bad addresses cost you

What goes wrong when a list is not verified.

Reps waste time on dead contacts

Every bounced email is a prospect your rep thought was real.

Bad data spreads

One wrong address gets synced to every tool connected to your CRM.

Reports get skewed

Bounced outreach makes reply and meeting rates look worse than they are.

How it works

How SimpleCold fits in

Three steps, using the tools you already have.

  1. 01

    Export or import a list

    Upload a CSV from your CRM, or import a HubSpot list straight into a verification job.

  2. 02

    Read the reasons

    Every contact gets a category and a plain reason.

  3. 03

    Update the records

    Import the results back and map Result and Reason to contact fields you can filter on.
