Here are the limits for each way of adding a list.
| How you add it | Limit |
|---|---|
| Upload a CSV file | Up to 100 MB |
| Paste rows | Up to 10 MB of pasted text |
| Link to a file | A public CSV file, up to 100 MB |
What file should I use?
A CSV file works best. Most spreadsheet programs can save your data as a CSV: open your spreadsheet and choose Save As (or Export), then pick CSV. The first row should be your column titles, like "Email" and "Name".
My file is too big
- Split it into smaller files and add them as separate lists.
- Remove columns you do not need before saving — a list with just emails is much smaller.
- If you regularly work with very large lists, you can use our API instead, which is built for big jobs. See the API & developers section.
