Warmer
AI sales enrichment that turns prospect CSV files into researched, personalized outreach messages.
About Warmer
Warmer is a B2B sales enrichment platform for turning prospect lists into personalized outreach. Teams upload a CSV, and the service adds social-profile and company information before generating a distinct message for each lead. Email validation can check deliverability, while CSV and JSON exports help move the enriched records into sales workflows. API access supports custom integrations, and the site names Salesforce, HubSpot, Pipedrive, Outreach, Salesloft, and Zapier as compatible parts of the wider sales stack. Credit-based subscriptions scale from 500 to 10,000 credits per month. Growth is the entry plan for smaller campaigns; Professional adds email validation, API access, and priority processing; Scale adds priority support, custom API limits, and a dedicated account manager. This structure suits outbound teams that want to reduce manual research while retaining control over where enriched records are sent. Adoption still requires a recurring subscription, sufficient credits for campaign volume, and a workflow for reviewing AI-generated personalization before sending it.
Best for
Best use cases
A campaign begins with a CSV of names and companies and needs enriched records before outreach messages are drafted.
An outbound workflow needs social and company context, email validation, and personalized copy before records move into a CRM.
A high-volume operation needs to export enriched data or connect processing to custom tools through a REST API.
Compare before choosing
Credit-based tiers make monthly capacity explicit, but campaign volume must fit within an allowance of 500, 2,500, or 10,000 credits.
CSV and JSON exports offer broad workflow portability, while direct API access begins with the Professional subscription.
The product combines enrichment and message generation, reducing tool handoffs but keeping AI-copy review inside the sales team workflow.
