CSV Upload lets you add contacts from your own tables - CRM exports, event sign-ups, webinar attendees - directly to a Lusha Engage sequence. No Lusha credits are consumed when uploading a CSV.

​
CSV file requirements

Each contact must include at minimum: First Name, Last Name, and Email Address. Including additional fields like Company and Industry is recommended - they can be used as personalisation variables in your emails. File limits: CSV format only, up to 20 MB, maximum 10,000 rows, maximum 50 columns, at least 2 columns of data per contact. Each sequence can hold up to 2,000 contacts - split larger tables across multiple sequences if needed.
Use Lusha’s CSV Enrichment to fill in missing data points before uploading, so your contacts are fully profiled when outreach begins.
