Import contacts from CSV or XLSX
SubsiMail accepts both plain CSV and Excel (.xlsx) files, with a column-mapping step in between so your spreadsheet's headers never have to match SubsiMail's field names exactly.
1. Upload the file
Go to Contacts → Import and choose your file. For .xlsx files with multiple sheets, you'll get a sheet picker; you can also set a start row if your real header row isn't row 1 (useful for exports with a title or logo row above the data).
2. Map columns
Each column in your file gets its own row on the mapping screen, with a preview of its first few values so you can confirm what you're actually looking at. For each column, choose where it goes:
- Name, Email, or Company — SubsiMail's built-in fields
- An existing custom field
- Create new field — adds a new custom field on the fly, named after the column header
- Ignore this column
SubsiMail pre-suggests a mapping based on header text (a column called "E-mail" or "Company Name" maps itself), so most imports just need a quick review rather than manual mapping from scratch.
3. Choose duplicate handling
If a row's email already exists in your contacts (case-insensitive match), choose whether to:
- Skip it, leaving the existing contact untouched, or
- Update the existing contact with the new row's values
You also choose whether imported contacts go into an existing list or a brand-new one you name on this screen.
4. Confirm
Submitting shows a summary: how many contacts were created, updated, skipped as duplicates, or skipped for missing/invalid email addresses.
