# Is there a limit to the size of the CSV file I can upload to import my contacts?

Notifyre allows you to import contacts via CSV for easy bulk management. While there is **no hard limit** on the file size, we **recommend a maximum of 25,000 contacts per CSV upload** to ensure smooth processing and avoid potential performance issues.

 

You can still store **unlimited contacts** in your Notifyre account, this suggested limit applies only to each individual import.

 

### Best Practices for Importing Contacts

- If you have more than 25,000 contacts, split them into multiple CSV files.
- Make sure your file is correctly structured before uploading. Refer to [our guide  for detailed instructions on how to format your CSV file.](https://support.notifyre.com/contacts/how-to-import-contacts?hsLang=en)
- Check for duplicates before uploading to keep your contact list clean.
