CSV and Excel import

Mail merge from a CSV or Excel file, columns and all

Upload a CSV or Excel file straight from your computer and match its columns to fields — no Google Sheets step. Fusomail checks every address, merges duplicates and keeps your extra columns for personalising emails.

What it does

  • CSV or Excel, no Sheets

    Save your list as .csv or .xlsx from Excel, Numbers, a CRM or Google Sheets, and upload the file. Nothing has to live in Google Sheets.

  • Match columns once

    Tell Fusomail which column holds the email address and the name. Every other column is kept as a field.

  • Addresses checked

    Addresses that cannot work, such as ones without an @ or with spaces in them, are flagged before they waste a send.

  • No duplicates

    The same address twice in a workspace is merged into one contact, so nobody gets your email twice.

  • Lists and opt-outs

    Keep contacts in lists, such as “Agencies in Pune” or “Event 2026”. Contacts who unsubscribed earlier stay unsubscribed, even if they appear in a new file.

  • Export and delete

    Download your contacts whenever you like, and delete any contact or list for good.

Questions about CSV and Excel import

Do I need Google Sheets?

No. Upload a .csv or .xlsx file from your computer. If your list is in Google Sheets, download it as CSV or Excel first. Older .xls files need saving as .xlsx or CSV.

Do you sell or share my contacts?

No. Your contacts are used only to send your own campaigns. We never sell them, share them, or email them ourselves.

Can I import a list I bought?

No. Our terms forbid bought, rented or scraped lists. You need a lawful reason to email each person on your list.
