When importing a list into LeadGrabber for appending email or phone, you need two columns minimum and those are the contact's full name and company name.

If you have the web url or web domain of the company, you can import that too. This helps in the append email process, but this not mandatory.

You can append as many records as your license permits you. If you are short of the required append counts, reach out to us at support@egrabber.com for a top-up.
