If you have spreadsheets of contacts, you can upload them to sequences through importing CSV files. You can import contacts into new and existing sequences. 

This is the recommended format for CSV files:

You'll want to include the contact's first name, last name, email, title, company, and website. It's important to include the email and website columns, especially if you're planning to look up missing work emails. 

Additional columns can be added if you'd like to import additional information for the contact. Be sure to add custom fields to the sequence first before importing the CSV file so you can map the data correctly.

Importing contacts into a new sequence

If you're importing a CSV file into a new sequence, you can click on the "Import CSV" button once you've created a sequence. 

Importing contacts into an existing sequence

To import your CSV file into an existing sequence, select the sequence and then click "Import CSV". 

From there, you can drag and drop your file or click "browse" to upload it. The file must be saved with a .csv extension in order to upload it to your sequence. 

Mapping CSV columns to sequence custom fields

During the file import, you can select how to map the CSV columns to the sequence custom fields within Interseller. 

If your CSV file is missing some email addresses, you can toggle the "Lookup Missing Emails" option to locate the missing emails to add them in. Toggling this option on will count towards your lookup credits and can slow down your import, especially if you're importing over a thousand contacts. Once you click "Import CSV", your contacts will import and you should be all set. 

If your CSV file doesn't have any missing emails, you'll bypass the third step for looking up any missing emails and see the finished import.

If your CSV file only contains email addresses, you can still import the file. There's a 32MB limit for each imported file.
